Motivation: Don't Give Up If You Fail at First
Are you one of those people who tries something just once? If you succeed then you are very happy. However, if you fail at first, you tend to give up very quickly and says something like, "I'll never be able to do such and such."
You then carry around the internal message that you will never be able to succeed in what you have just failed to do. Just think for a moment about a baby learning to walk. Do you remember seeing a toddler trying to stand, warbling through moment and then falling over. Do they say to themselves, "that's it I failed I'm never going to walk." No, they keep on trying. They get up and fall over many many times take the steps they are striving to do.
So you too, as an adult, must bear in mind the scenario of a young child learning to walk. If you do something and fail to achieve what you wish for then be prepared to try again and again. Each time you can learn from the time before, so that you adapt the next attempt in a way more likely to succeed. People say that there is no such thing as failure, only a learning experience.
If you feel you've failed something, ask yourself how you could achieve the same result in a slightly different way. Think about your other options and do something differently when you try again. Sometimes it's about where you were trying to do something or whether you have the skills to do so. If your skills are lacking then that is the area you must address for you try again.
You may not have succeeded because of your own mindset about your own capability and whether somebody such as you could actually achieve what you are striving for. Look around and find other people who have achieved what you want and discover what they did which was different from the way you approach the task. Although everyone has their own individual way of achieving something, you can always learn by observing people who have already achieved success in that area.
So don't give up when you metaphorically fall over. Get yourself up, brush yourself down, take a few deep breaths and start all over again. Say a few positive affirmations to yourself such as "I can do this."
You may be amazed about how much you can achieve when you get into the right mindset for success.
Stress - Personal Traits - Lack of Confidenc
BY Dr. Ron Bailes
In my experience, people reading and body language are critical when assessing an individual. Personal traits stress, such as lack of confidence, can be exemplified in an individual's behaviors and attitudes. Even those who seem to be very confident lack self-assurance on some level. The difference between those who allow it to debilitate them and those who don't is the courage to continue on, in spite of their fears. Lack of confidence is just one of the many ways to express fear.
One way to overcome fear or lack of confidence is to not let it hold you back. Learn to release the idea and the thoughts of "if something goes wrong", (and it probably will) or "what if it doesn't work, I'll look stupid or it will look like I don't know what I am doing". By simply developing the idea in your subconscious that "If something goes wrong, I'll figure out a way to fix it", you begin to release the fears that have invaded your ability to think positively.
When you resolve within yourself the idea that if something goes wrong or doesn't turn out the way you had planned, it simply means that there were parts of the equation that you miscalculated or you were unaware of part of the process. With this attitude you gain the knowledge to move forward. An example would be, to produce a projection of a completion date on a project that you are working on but are unfamiliar with the details. As you are unable to meet the deadline, due to the factors that you had no knowledge of or control over, you can make the adjustments and keep on track. Entrepreneurs seem to inherently have this capacity or belief within certain areas of their lives.
I have first-hand knowledge from developing my body language video course. Having never tackled such a project, I was continually making unrealistic deadlines and constantly having to adjust them. I never became discouraged, I knew going in that I was in an area that would require additional learning on my behalf. Even though I know the subject, and know it well, the planning, filming, editing, producing and marketing required tenacity and the self-confidence that no matter what happened, I or my team would overcome the obstacles.
Also, working from the premise that if there is a problem you can learn from the experience and make proper changes to move forward. Confidence must be intrinsic, it comes from within oneself. As you become more relaxed and less tense and release the fear, you begin to develop more confidence in yourself. With this self-assurance you will develop your ability to do what you normally have to do each day without fear of failure, without fear of consequences, and without fear of unnecessary anxiety.
What I'm saying here is, stop being afraid to try something new or chase your dreams. Even if you know very little about what is involved, do your homework and give it your best shot. You can always make changes and adjustments as you proceed. Pay attention and learn from what doesn't work. Keep this in mind, when you fail to chase your dreams because of a lack of confidence and fears, you give others control and power over your life. By learning from the experience, it is no longer a failure. And of course, with a change of attitude and the willingness to learn from mistakes, you build confidence in other areas of your life as well.
Lack of confidence goes hand-in-hand with insecurity. It can have roots as far back as childhood. It may come from experiences in school or adolescent issues, as we muddle our way through puberty. Being fired from a job may even rock or destroy one's confidence. It can be shattered from a divorce, especially after being in a long term relationship or marriage. Entering the dating scene in your late 30's or 40's, or even older, with only "left-over tools" that you acquired in your teens can cause you to lack confidence in yourself. Lacking the skills to deal with workplace politics can have a negative effect on your self-confidence and your financial future.
I have dealt with this from both males and females in all age groups. The lack of confidence in their ability to even go about meeting someone new and starting over can bring on an enormous amount of stress. This also spills over in other areas of their life. The stability of their home life and the routines that they have created for themselves, gave them the confidence that they needed to take on and tackle just about anything that entered the picture. They had the perceived backup that is now no longer a part of their life. Finding ways to rebuild your confidence will certainly help you deal with those progressive accumulating events, customary anticipated life events, as well as the unexpected life events.
One suggestion that I recommend in an effort to begin to build your self-esteem and self-confidence, is to make an asset list. Not an asset list of your things and possessions, but an asset list of who you are and who you would like to become. Begin with two pieces of poster board. On one board, at the top title it "Who I AM", with the other "Who I am BECOMING". Be sure to underline the titles and write it big enough to see it several feet away.
Now start the list of "Who you are" and "Who you are becoming." For example, are you kind? If so, write it under "Who I am", if not, write it under "Who I am becoming." Are you forgiving, understanding, happy, positive, confident, do you have self-esteem? Write them under their respective headings. Only write down the positive of what you are. If you are "unhappy", then write "happy" under the heading of what you are becoming. I think you get the picture.
You can also write your accomplishments under the "Who I am" title. During the day, as you think of something you are or would like to become, while you're work or on the go, jot it down on a piece of paper and add it to the asset list when you get home. If you deal with jealousy, write on the "Who I am becoming"-- less jealous. The same goes for feelings of insecurity and inadequacy. Simply add to "Who I am becoming" list, more secure and more adequate. It is very important to only write the positive of what you are or what you are becoming.
Hang your asset list on your bedroom wall, so you can see it first thing when you wake up in the morning, as you get ready for your day, and the last thing you see before you go to sleep. Everyday, sit in front of your asset list for 30 minutes and do a meditation or simply sit quietly, where you can think undisturbed. The meditation that I use the most is an undirected meditation. This is where I sit in front of my asset list, and stare at it. Sometimes I might focus on a particular word or words on the "Who I am" list and other times I am drawn to the "Who I am becoming" list.
Lack of confidence can be overcome simply by reprogramming yourself. It doesn't have to come from the reassurance of others. It is you making the changes and becoming the person you desire to be and not through the want of approval from others and what they think you should attain in life.

The Beauty of Friendship
BY Karishma Kristina Tannan
Friends are people who will be there for us when we really need someone the most, but then there are a few who are to enjoy with us and run away when you need someone the most. There are the some that let us be ourselves but there is always that one person who is so close to you and you know that this person will understand even your silence. This person is more as a family to you and you know even at 3:00 AM you can make this one phone call and this person will still be there for you.
Friendship is one of the most beautiful relations you can have. And it is even better with that special friend who you love the My best friend and I fight like crazy, at times I even pull her leg saying that I am going to get married to her. We both share one main thing in common, we both love dogs and the best part is she has one of the pups that my lab had given birth to.
We both keep on talking about the pups and telling each other how naughty they are. Sometimes she even asks me what to do if a dog is not well since she feels that I know a lot about dogs since I have had them for the past 11 years.
Apart from our dogs, we talk about our problems, about things that bother us. We make it a point to talk on a regular base. No doubt, there are days where she gets upset with me or vice versa, but then in the next second, the anger is gone and we are happy again. Between the both of us, I am short tempered but with her around, I cannot be angry for too long, she will always find a way to make me laugh.
Life has not been fair to both of us, but we still are able to trust each other and know that no matter what happens there is this one person on this earth to whom we do not need to prove ourselves. There is one person you do not need to explain what and why you did it. Who does not care if you are right or wrong but still stands by you in front of everyone and shouts at you if you are wrong when no one is around.
This person just loves you for whom you are. This one person can see things, which you also may not be able to see. This one person knows you so well that even if someone comes and tries to tell them something bad about you, it still does not change a thing since they know who you really are and is confident about whatever you do and will always stand by you. This person is always there for you no matter what the situation is and advises you or goes out of their way to help you. This person is your guide, your friend. To this special person I must say a big thank you who thought me the BEAUTY OF FRIENDSHIP. So in short of you had to say what a friend is then:-
F-forgiveness
R-respect
I-Impartial
E-Emotional
N-Nurture
D-Dependable
And Friendship would be
F-Fun
R-Rational
I-Intuition
E- Endurance
N-Never Ending
D-Devotion
S-support
H-honesty
I-inspiration
P-Perfect
Couple Communication - Learning to Identify Feelings As a First Step in Communicating Them
BY Peggy Ferguson
Couples often come into counseling with one spouse complaining about the other spouse's lack of emotional involvement in the relationship. They each give very different meaning to the interaction that they have in their relationship. The spouse that has been described as emotionally unavailable or uninvolved, often views the other partner as critical and demanding, and feels as if s/he is in a no-win situation.
In some ways each party is probably trying very hard to show the other partner that he or she is loved. The problem is that each brings to the relationship beliefs, attitudes, and emotional baggage about how to go about it. Unfortunately, most couples will not share the same beliefs, attitudes, and early life learning. So, of course their ideas and their methods will not match the other person's expectations. They won't give the same meaning to the same events.
Each party wants to feel loved, important, valued, and respected. Many times, one or both partners expect the other partner to know what they want or need, and to give it to them without having to ask for it. This expectation of mind-reading gets in the way of feeling loved and important. It gets in the way of effective communication and problem solving. It virtually guarantees that the person expecting the other "to know" will be hurt and disappointed. Most couples are not so "tuned in" to each other that they finish each other's sentences. Yet that is often an expectation of the one of the partners.
It is crucial when trying to communicate, and ultimately to problem solve on relationship issues in your life, that you have the ability to identify and communicate feelings. Many people have a difficult time identifying exactly what it is that they do feel. Some people have had inadequate training in recognizing that they are having a feeling then appropriately labeling that feeling. It is very difficult to tell someone else what you are feeling if you don't have the vocabulary to accomplish it. To assist in correctly identifying and labeling the feeling, use this exercise:
Remember a recent event when you felt angry. Then explore these questions:
- What does anger feel like in your body?
- Does your heart beat faster/race?
- Does your breathing quicken?
- Do you breath more shallowly or more deeply?
- What does your stomach/guts do? Are they churning; do they feel hard, or do you feel nauseated?
- What do your muscles do? Are you tense? Does your hand ball up into a fist?
- Does Your blood pressure go up? Do you turn red? Do you have a vein that sticks out and throbs.
- Is your chest tight?
- Do you experience high energy or low energy. Do you feel compelled to take some action? What kind of action?
What does your body feel like when you experience fear? Does your body experience some of the same things that you do with anger? What is the difference? Can you tell the difference when you experience either feeling?
What does hurt feel like?
- Heart beat/pulse fast or slow
- Breathing fast or slow; deep or shallow
- Stomach/Guts nausea or churning or knotted
- Muscles tense, weak
- Temperature hot or cold
- Chest tightness or heaviness
- Energy high or low
- Action compelled to act or unable to act
Use this list of physical reactions of feelings to identify how your body reacts to each of the feelings listed below. This list encompasses common reactions for emotions, but there is a great deal of variability possible. You might high some different physical reactions to feelings that are not given here. It is important to identify what your body does with a specific feeling so that you can correctly label the feelings you have.
- Fear
- Anger
- Shame
- Guilt
- Hurt
- Sad
- Lonely
- Helpless
- Joy
It is vitally important to know appropriate labels for your feelings. If you only know two labels for feelings-angry and happy-and you experience hurt, the label that you choose to communicate your feeling of "hurt" to your loved one will probably be "anger". Your communication of anger will probably hamper your attempts to effectively reveal what is going on with you. Your loved one probably will not be able to read between the lines and see the "hurt". They will probably take you at your word, that you feel "angry". You will not have successfully communicated your feeling.
It is important to be able to distinguish between and among feelings because feelings often get paired up quite quickly. Common pairings are "fear and anger" and "hurt and anger". Sometimes people experience different feelings in rapid fire fashion. It can happen so quickly that you may not even be aware of the first feeling before it turns to something else - usually anger. Often, the first feeling that you experience is the most important one to communicate with significant others. The second feeling may be a defense or a guard against experiencing the first feeling. An example of how the first feeling may have more significance for the relationship is when a parent has been waiting up all night for an adolescent who has missed curfew, to get home. When the adolescent opens the door at 3:00 in the morning, the abject terror and fear of what might have happened to the child, gives way to the anger. It is, of course, typically the anger that is expressed. If the fear gets expressed at all, it is usually much later. The erring child hears the anger and not the fear.
As with any skill, practice makes for improvement. Human beings experience a range of emotions, not just "anger" and "happy". The more skilled that people are at identifying and communicating this range of emotions, the better able they are to problem solve and work through feelings. The less skilled that you are in identifying and communicating feelings, the more likely you are to act them out in ways that are detrimental in various areas of your life.
Adolescence Obesity
BY James Rouse
Do we have reason to be concerned about adolescent obesity? Over the past three decades the number of overweight and obese children has nearly tripled. Statistically adolescent obesity accounts for over 17% of those numbers. Overweight children have a higher risk of developing lifelong health problems more than their adult counterparts because obesity during childhood is associated with an increased rate of illness and even death in adulthood. Adult obesity is far more difficult to treat which means if adolescent obesity is not treated the consequences could be grave.
There are many reasons for the increase in adolescent obesity one particular reason is the world that we live in. Technologically we have advanced and gurus are always trying to find ways of simplifying our lives. The problem is that because of the almighty dollar some of the technological advances are targeting our youth. Video games, computers, and big screen television sets have all contributed to sedentary lifestyles. The lure and excitement of these gadgets also come at a price with advertising. Particularly the internet and social networking which entices adolescence with free ring tones and other offers to gain access to an e-mail address. The result is e-mail marketing for convenience foods and fast foods that are high in fat and calories. The most common cause, of course, is eating too many calories and not getting enough exercise.
Everyone needs and has some fat tissue in their bodies but when teens have too much it results in adolescent obesity. There are several different methods used to calculate body fat percentage the most commonly used method is called the body mass index. This is a measurement of an individuals height in relation to weight. The result is a figure that is used to determine their body mass index. There are three categories of obesity. Class I obesity is defined as a BMI score of 30-34.9, and Class II obesity is defined as a BMI of 35-39.9. Lastly, Class III obesity, also known as morbid obesity or severe obesity, is defined as a BMI score of 40 or higher. Based on these numbers, as many as one-third of all Americans are considered obese.
Adolescent obesity takes no prisoners. It effects all ethnic groups, religious groups, genders, financially secure and insecure families, educational levels and more. There are many influences for the increase in overweight children such as environmental factors. Parents are spending less time with their children because of the need for two income sources and they are unable to monitor the eating habits and exercise that their children get. Issues in school with peer pressure and taunting or teasing. Many overweight children get picked on leading them into isolation and contributing to adolescent obesity. Family conflict also contributes to obesity in children. When families are struggling many times children become secondary and they turn to food to nurture hurt feelings. Parents become less aware of the effects of the conflict on their adolescents and how they are venting their anger and pain.
Solving the problem of adolescent obesity can be accomplished with the help of schools, the community and most of all the parents. Focusing on healthy eating, healthy lifestyles, exercise, and doing it as a family. It all starts at home. Parental involvement and support is critical for adolescents to gain control of their weight.
Teen Pregnancy
BY Celia Namart
Besides the stress of knowing that she is pregnant, there is also the fact that now she has another life to think of and care for. Girls that engage in unprotected sex often end up confused, lonely and in great need of guidance in coping with teenage pregnancy. This seems to hold true for almost 34% of all teenage girls in America who get pregnant before the age of 20. Even more shocking is the situation in England where one out of every 5 births recorded is to a teenage girl. Since these statistics alone prove that these teenagers are lacking in knowledge and are participating in unprotected sex, there needs to be action taken, more of a community approach to providing proper knowledge to teenage girls about pregnancy prevention.
Even in this modern age, people are still embarrassed to talk to their children about sex and its consequences. While this is natural and difficult initially, in the long run it would be very help the teenager avoid making a serious mistake. Having an open-minded, educational talk will not only prevent your teenage child from getting pregnant, but might also eliminate the possibility of sex at too early an age. It will also educate your child about the various sexually transmitted diseases [HIV, aids, etc.] and make them more cautious about engaging in sexual activities. Your child will be a lot more aware of the consequences and will be prepared to take appropriate action.
There are various ways for women to avoid pregnancy, using contraceptives being one. Contraceptive birth control pills, This is the form of birth control method where "pills" are taken by girls to stop production of certain hormones that cause ovulation. While this is a useful technique, requiring the person to take a pill everyday to prevent ovulation, it does not eliminate the chances of getting infected or infecting someone else with a sexually transmitted disease.
While it may be portrayed socially and by the media that contraception completely eliminates the chances of pregnancy, it is not true. There is still a 3-5% chance of getting pregnant. So the best possible way to prevent teenage pregnancy is to practice abstinence. Abstinence means not having sex at all. By abstaining from sexual intercourse, many unwanted births will be prevented. This is the best way to avoid being infected by sexually transmitted diseases and possible infections in the vagina and uterus. While there is a good chance that their friends might pressure them into having sex, having the right knowledge and the courage to say no is all that matters.
Overall, the young people today are being bombarded by the television and advertisements everywhere on sexual issues, the natural feelings and the teenage drive many to make costly mistakes, what is needed is better understanding of the consequences of early pregnancy and the information about trying practicing safe sex. Since it is sometimes difficult to approach teenagers, the young people should make their own decisions out of the knowledge they have gained.
Sleep Makes Your Memories Stronger, and Helps With Creativity
ScienceDaily (Nov. 12, 2010) — As humans, we spend about a third of our lives asleep. So there must be a point to it, right? Scientists have found that sleep helps consolidate memories, fixing them in the brain so we can retrieve them later. Now, new research is showing that sleep also seems to reorganize memories, picking out the emotional details and reconfiguring the memories to help you produce new and creative ideas, according to the authors of an article in Current Directions in Psychological Science.
"Sleep is making memories stronger," says Jessica D. Payne of the University of Notre Dame, who co-wrote the review with Elizabeth A. Kensinger of Boston College. "It also seems to be doing something which I think is so much more interesting, and that is reorganizing and restructuring memories."
Payne and Kensinger study what happens to memories during sleep, and they have found that a person tends to hang on to the most emotional part of a memory. For example, if someone is shown a scene with an emotional object, such as a wrecked car, in the foreground, they're more likely to remember the emotional object than, say, the palm trees in the background -- particularly if they're tested after a night of sleep. They have also measured brain activity during sleep and found that regions of the brain involved with emotion and memory consolidation are active.
"In our fast-paced society, one of the first things to go is our sleep," Payne says. "I think that's based on a profound misunderstanding that the sleeping brain isn't doing anything." The brain is busy. It's not just consolidating memories, it's organizing them and picking out the most salient information. She thinks this is what makes it possible for people to come up with creative, new ideas.
Payne has taken the research to heart. "I give myself an eight-hour sleep opportunity every night. I never used to do that -- until I started seeing my data," she says. People who say they'll sleep when they're dead are sacrificing their ability to have good thoughts now, she says. "We can get away with less sleep, but it has a profound effect on our cognitive abilities."
Friendships, Peer Influence, and Peer Pressure During the Teen Years
Facts About Friendships, Peers, and Adolescence
- Parent relationships are not necessarily undermined by peer relationships. During adolescence, relationships between parents and teens are more often re-negotiated rather than rejected. During adolescence, teens become increasingly autonomous and take on more adult roles. They also develop their own ideas and start mapping their own lives. They begin to spend more time with and value their friends more than they used to. Thus, it might seem as if they are starting to cut ties with parents and reject their ideals. In fact, rather than cutting off ties, teens are just renegotiating the parent-child relationship. What this means is that they are beginning to shift the relationship to incorporate their increasing independence and maturity. As teens become more mature, the type of relationship they have with their parents naturally begin to shift as the teen begins to mature.
- While it seems that teens are influenced by their peers, parents continue to be the most influential factor in their lives. Despite fears parents have about their teens rejecting their values and beliefs, parents continue to be of significant influence. Teens report having political, religious, and general beliefs similar to their parents, and consider their parents as being highly significant and influential in their lives. Positive relationships between parents and teens also equip youth to have healthy relationships with friends. Teens who have high quality relationships with parents also report having a positive relationship with their peers.
- Parent-adolescent conflict increases between childhood and early adolescence; although in most families, its frequency and intensity remain low. Typically, conflicts are the result of relationship negotiation and continuing attempts by parents to socialize their adolescents, and do not signal the breakdown of parent-adolescent relations. Parents need to include adolescents in decision-making and rule-setting that affects their lives.
- Parents who continue to communicate with their teens, even when there are conflicts, actually maintain closer relationships. While it might seem futile to talk to teens when it leads to conflicts and disagreements, most teens continue to report having a close relationship with their parents, and as mentioned earlier, they still report parents as being a significant influence on their lives. So parents need to continue talking to their teens and maintaining an open line of communication, rather than simply trying to avoid disagreements.
- Teens often have multiple layers and groups of friendships. Unlike in childhood, when friendships usually meant two or more close friends, teens often have multiple friends and belong to multiple groups. They might have intimate and close relationships with one or a handful of individuals, and might also belong to one or more ‘cliques’ or groups of friends that have similar demographics (sex, race, socioeconomic status), orientation towards school, and other interests.
- Peer friendships are dynamic. This simply means that peer friendships may change. For instance, while teens can have friendships that are long term, they often move from one clique to another, and they might develop new friendships and lose others.
- Peers tend to choose those who are similar to themselves. Whether it is gender, age, socioeconomic status, ethnicity, or interests, teens tend to gravitate towards those who are more similar to them.
- Peer friendships can be a healthy venue for positive youth development. Peer friendships can be a safe place for youth to explore their identity, learn about social norms, and practice their autonomy. Healthy friendships provide youth with social support for dealing with some of the challenges of adolescence, and can also provide youth with some of the most positive experiences during those years. Many teens report having some of the happiest and most fun moments with their peers, likely due to shared interests as well close relationships.
Effective Strategies for Coping with Peer Pressure
- Nurture teens’ abilities and self-esteem so that they are equipped to foster positive peer relationships and deflect negative pressures. Adolescents with positive self-concept and self-worth will be less likely to be easily swayed to follow others’ negative influences. It is essential that these aspects of positive development should be encouraged in youth.
- Encourage positive relationships between significant adults and teens. Parents, teachers, school counselors, other relatives and professionals should try to have constructive and positive relationships with teens. These can serve as good models for healthy relationships, and can be a venue through which the teens can feel valued and where they can develop positive views about themselves. Youth should know that they can go to these caring adults for help or advice about their peer relationships.
- Encourage diverse relationships. Parents, teachers, community leaders, and clergy can model appreciation for ethnic, gender, socioeconomic status, religious, and other differences and support cross-group friendships. Schools and youth organizations can assist by encouraging youth from diverse backgrounds to work and play together.
- Support parent education programs for families with teenagers. Parents need to be better informed about the dynamics of adolescent peer groups and the demands and expectations teenagers face in peer relationships. Information is available through various sources including books, some parenting magazines, and other publications such as this one. Keep your eye out for programs particularly targeted towards families and teen issues that might be available. Seeking information is not a sign of weakness, and showing interest in these issues might actually show your teens that you are concerned about them.
- Equip youth with the skills necessary to resist negative behaviors, as well as to make good decisions. Teens will inevitably be confronted with situations where they will have to make a decision whether or not to engage in certain behaviors, whether to give in to peer pressure, and also to make other difficult decisions. It is essential that youth are given the necessary skills to analyze the situation and make the appropriate decision. This includes helping youth develop the skills for ‘costs vs. benefits’ analysis — teaching them to look at both the negative and positive sides to making a decision. For instance, if being pressured to smoke, the teen should be able to think about what the possible desired outcomes are (e.g., peer acceptance, looking “cool,” feeling excitement about trying something new) with the possible undesirable outcomes (e.g., becoming hooked, the health issues, smelling bad, the financial costs).
- Teaching youth exit strategies or ways to say ‘no’ to negative pressures. It is best to try to deal with peer pressure before it even happens. Talk to youth about potential scenarios, and think through strategies together on how to deal with those scenarios if they arise. This could be done by discussing hypothetical scenarios or even role-playing. It is helpful to think about these things ahead of time rather than dealing with situations as they occur or trying to recover after they happen.

Coffee and a Sweet Treat to Think Better? Caffeine and Glucose Combined Improves the Efficiency of Brain Activity
ScienceDaily (Nov. 23, 2010) — The combination of caffeine and glucose can improve the efficiency of brain activity, according to a recent study in which functional magnetic resonance imaging was used to identify the neural substrate for the combined effects of these two substances.
The study, which was published in the journal Human Psychopharmacology: Clinical and Experimental, is led by the researchers Josep M. Serra Grabulosa, from the Department of Psychiatry and Clinical Psychobiology at the UB and a member of the August Pi i Sunyer Biomedical Research Institute (IDIBAPS); Ana Adan, a lecturer from the same department and a member of the UB's Institute of Brain, Cognition and Behaviour (IR3C); and Carles Falcón, a member of the Biomedical Research Networking Center in Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN).
"Our main finding is that the combination of the two substances improves cognitive performance in terms of sustained attention and working memory by increasing the efficiency of the areas of the brain responsible for these two functions," explains Josep M. Serra Grabulosa. This supports the idea of a synergistic effect between two substances, in which each one boosts the effect of the other.
Specifically, the team found that individuals who consumed caffeine and glucose in combination showed reduced brain activation associated with the task in the bilateral parietal cortex and the left prefrontal cortex -- two regions that actively participate in attention and working memory processes. The reduced activity and the fact that no drop in behavioural performance was observed during the task suggests that the brain is more efficient under the combined effect of the two substances, since it needs fewer resources to produce the same level of performance than required by those subjects who were administered the placebo or who took only caffeine or glucose.
For the study, the team of researchers from the UB used functional MRI to analyse brain activity during the n-back task, which evaluates sustained attention and working memory -- basic capacities in improving everyday cognitive tasks. In a double-blind randomized design, participants were tested after drinking a study beverage containing either caffeine, glucose or the two combined or a placebo consisting only of water. Tests were conducted with a sample of 40 healthy volunteers at the Diagnostic Imaging Centre of the Hospital Clínic de Barcelona.
An earlier study by the same research team on the effects of caffeine and glucose consumption revealed improvements in attention span and declarative memory without significant alteration of the participants' subjective state. The conclusions suggested that a combination of caffeine and glucose has beneficial effects on attention (sequential reaction time tasks) and learning and on the consolidation of verbal memory, none of which were observed when the substances were consumed separately.

Less Salt in Teenagers' Diet May Improve Heart Health in Adulthood
ScienceDaily (Nov. 15, 2010) — Eating smaller amounts of salt each day as a teenager could reduce high blood pressure, heart disease and stroke in adulthood, according to research presented at the American Heart Association's Scientific Sessions 2010.
Conducting a sophisticated computer modeling analysis, researchers projected the nationwide health effects of a 3-gram reduction in dietary salt from processed foods consumed by adolescent boys and girls.
Teenagers eat more salt each day -- more than 9 grams (3,800 milligrams of sodium) -- than any other age group, researchers said. The American Heart Association recommends no more than 1,500 milligrams of sodium per day for most Americans.
By reducing the salt teenagers eat each day by 3 grams, researchers projected through modeling a 44 percent to 63 percent (380,000 to 550,000) decrease in the number of hypertensive teenagers and young adults. They estimated a 30 percent to 43 percent decrease (2.7 to 3.9 million) in the number of hypertensives at ages 35 to 50.
"Reducing the amount of salt that is already added to the food that we eat could mean that teenagers live many more years free of hypertension," said Kirsten Bibbins-Domingo, Ph.D., M.D., lead author of the study and associate professor of medicine and epidemiology at the University of California, San Francisco. "The additional benefit of lowering salt consumption early is that we can hopefully change the expectations of how food should taste, ideally to something slightly less salty."
A one-gram-per-day reduction in salt consumption results in a small drop of systolic blood
pressure of 0.8 mm Hg, she said. "Reducing the salt in the teenage diet from an average of 9 grams to 6 grams would get teenage boys and girls to appropriate levels of salt intake."
Measurable health benefits over time as teenagers reach age 50 would include:
7 percent to 12 percent reduction in coronary heart disease (120,000 to 210,000)
8 percent to14 percent reduction in heart attacks (36,000 to 64,000)
5 percent to 8 percent reduction in stroke (16,000 to 28,000)
5 percent to 9 percent reduction in death from any cause (69,000 to 120,000)
About 80 percent of salt comes from processed or prepared foods -- 35 percent of that in cereals, breads and pastries.
"The hidden places of salt in our diet are in breads and cereals, canned foods and condiments, and of course fast foods," said Bibbins-Domingo, also co-director of the UCSF Center for Vulnerable Populations. "Most of the salt that we eat is not from our salt shaker, but salt that is already added in food that we eat."
Pizza is the biggest culprit of salt for teens according to data from the National Center for Health Statistics.
Manufacturers should continue to reduce salt in their foods in cooperation with local, state, and federal regulatory agencies, she said. Many major companies have already joined the National Sodium Reduction initiative and have voluntarily agreed to work to lower the salt content that is already added to processed and prepared foods.
