Red wine could mask testosterone levels, experts warn

Jan. 7, 2013 ? Red wine could give athletes and players a boost in the sports arena by increasing the amount of performance-enhancing hormone testosterone in their bodies, according to researchers from London's Kingston University.

However not only could the beverage help them to trophy success, it could also allow them to beat anti-doping tests. A team led by Professor Declan Naughton, from the University's School of Life Sciences, found that red wine might reduce the amount of testosterone excreted by the body, which could distort the findings of drug tests taken from urine samples.

Testosterone is a naturally-occurring steroid hormone present in both men and women. It can increase muscle mass, boost stamina and speed up recovery. Sportspeople, however, are prohibited from taking it, or a synthetic version of it, to try to gain a competitive edge.

Although red wine is not a banned substance away from the sports field, Professor Naughton's team has referred its findings to the World Anti-Doping Agency because of the newly-discovered side effect of potential change to the amount of testosterone in the body.

"Previous research has shown the effect over-the-counter anti-inflammatory drugs can have on enzymes," Professor Naughton explained. "Since many of these drugs are derived from plants, we decided to look at the effect particular foods and beverages can have on enzymes involved in testosterone excretion. We chose green tea and then red wine because both have a huge variety of natural molecules and we wanted to see if they affected the amount of testosterone excreted in urine."

The team found that a compound in red wine, known as quercetin, partially blocked the action of an enzyme called UGT2B17, which looks for testosterone and then sends a message to the kidneys to excrete it.

Professor Naughton stressed that the research had so far been conducted in test tube experiments and had yet to be trialled on humans. "A full clinical study would be needed to determine the effects on people but, if the same results were found, it would confirm that compounds in red wine can reduce the amount of testosterone in urine and give a boost to testosterone levels," he explained.

The effect of red wine on an individual would vary because of factors such as weight, fitness, health and diet, making it hard to estimate how much was needed to improve performance, Professor Naughton said.

Teetotallers are not exempt from the effects. In fact, the alcohol content of red wine has very little impact because non-alcoholic molecules are responsible for inhibiting testosterone excretion.

The team also found the results were the same for red wine extract in supplement form. The active compounds such as quercetin are found in many foodstuffs as well as supplements.

The findings have been published in leading international journal Nutrition. The research follows an earlier study from Professor Naughton's team which showed that green and white tea could also inhibit testosterone excretion.

Cup Color Tricks Taste Buds

60-Second Science

The same hot chocolate served in an orange cup was rated more 'chocolatey' than when it was served in cups of other colors. Christopher Intagliata reports.

More 60-Second Science

If you've ever dined with a stuffy nose, you know that what you smell strongly influences what you taste. But what you see matters too. Even the color of a cup can trick your taste buds. That?s according to research in the Journal of Sensory Studies. [Betina Piqueras-Fiszman and Charles Spence, The Influence of the Color of the Cup on Consumers' Perception of a Hot Beverage]

Researchers prepared store-bought hot chocolate, and served it in red, orange, white and cream-colored cups to 57 volunteers. The study subjects rated the sweetness, aroma, flavor and overall likeability of each cup of cocoa. Turns out hot chocolate in the orange cup was rated more likable and 'chocolatey' than the others?even though each cup had the same stuff.

Previous studies also suggest color matters. Increasing the yellow hue of a 7-Up can, for example, makes people think the drink tastes more lemony. Likewise, researchers say the orange cup might enhance the 'chocolatey' brown color of the cocoa, and enhance flavor. Since much more of the brain's cortex is devoted to vision than taste, what you see could matter as much as what your taste buds experience. So next time you're really savoring something, try feasting your eyes on something else?and see if the taste passes the test.

Conservative Rep. Todd Rokita Named Chairman of K-12 Panel

Rep. Todd Rokita, a
conservative Republican from Indiana, has been tapped to oversee the
House education subcommittee on K-12 policy.

That puts him in a powerful position for education policy?particularly if Brokedown Congress surprises everyone and somehow makes significant headway on the reauthorization of the Elementary and Secondary Education Act this year.

Case in point? One of Rokita's predecessors?Rep. Mike Castle of Delaware?was a member of the "Big 8" group of lawmakers targeted by the administration back in 2009 to help move an ESEA renewal. (In fact, Castle oversaw the K-12 subcommittee for years and was able to help put a significant stamp on federal K-12 policy?he was a major author of the bill that helped create the Institute of Education Sciences, and was a lead writer of the most recent renewal of the Individuals with Disabilities Education Act.)

But while Castle was known as a moderate, Rokita seems to have a lot more in common, politically, with conservative Rep. Duncan Hunter, who was at the helm of the subcommittee in the most recent Congress.

In fact, back in the winter of 2012, when the House education panel marked up bills to renew the ESEA law, Rokita stood out as one of the most conservative members of a very conservative bunch of lawmakers. He introduced an amendment to reduce the number of employees in the U.S. Department of Education, which was added to the bill.

What's more, he put forth?then withdrew?a game-changing provision that would have basically repealed the entire decades-old ESEA law?not just the No Child Left Behind Act of 2001. The legislation would have essentially allowed states to opt out of federal education programs and return the money to taxpayers.

Rokita, who as the former secretary of state in Indiana, has a lot of political experience, was elected to Congress in 2010, as part of the big, "tea party" wave. And he was seen as emblematic of his freshman class. Check out Rokita's interview with the Washington Post's Jennifer Rubin.

So far, Rokita hasn't sponsored any education bills. (Here's a glimpse at the ones he has put forward.) But he's co-sponsored quite a few, including a bipartisan piece of charter school legislation that passed the House and a bill to slim down the Education Department by eliminating more than 40 programs.

He's also supported the "A-Plus Act", which would allow states to opt out of federal accountability measures, and a bill to make English the official language of the United States, which could have implications for the education of English learners.

It sounds like Rokita, the father of two young children, is excited to take over the subcommittee. And he thinks the Hoosier state, which recently embraced vouchers and a host of other changes, is on the right track when it comes to ed policy.

Here's a snippet from his recent statement:

New Year, New Career: 5 Most Popular Fitness ... - Diets in Review

The American Council on Exercise (ACE) conducted a survey and discovered that for most fitness professionals, this career was not their first job. Many had pursued other avenues only to find that the fitness industry was where their true passions lied. It assumed that many find their love for fitness later in life. Many in the business will tell you that since they were devoting the hours of a full time job to their own fitness, they decided they might enjoy getting paid along the way.

?I was in banking for 15 years before making the leap to personal training full time,? said Pamela Hernandeez, a personal trainer at ThriveFit.com. ?In 2009, when the financial services industry collapsed, I was fortunate not lose my job but a lot of people I worked with did. It made me step back and realize how much I had come to dislike my job.?

She kept both jobs for a while as she she pursued her ACSM CPT fitness certifications and to ensure her passion and the clients would be there to pay the bills. As a banker, she says she hated what she was doing and how it didn?t offer any real value for people?s lives. With a full-time fitness career, she gets to make a huge impact on the lives of others. ?I knew I had found my calling. I was able to quit my banking career in June 2011. I have never looked back!?

Sound like you?

Some of the most popular careers in the fitness industry include health coach, personal trainer, dietitian, spin instructor, and Zumba instructor. Before you consider taking one of these paths this year, learn more about what each profession entails.

DIETITIANS

John LaRosa, who has 20 years of experience tracking and analyzing diet programs at MarketData, shared some helpful tips about these careers. When it comes to getting certified for these positions, some require much more than others. LaRosa noted that dietitians have to be licensed by the American Dietetic Association, or the Academy of Nutrition and Dietetics as they just changed their name in 2012. The Academy states that a registered dietitian must complete a bachelor?s degree or higher and more than 900 hours of training, while a dietetic technician is required to complete an associate level degree and 450 hours of training.

SPIN INSTRUCTOR

Spin instructors are often certified by the gym in which they teach. This can often require consistent training in order to remain apprised of the new findings and the best ways to safely teach novice athletes. A benefit to becoming a spin instructor is that in most cases, in order to teach, you have to do the same workout with the class. A great case of getting paid to workout.

ZUMBA INSTRUCTOR

When it comes to Zumba, things are different. Since Zumba is a franchise, LaRosa pointed out that the Zumba website states, ?Anyone interested in becoming a Zumba instructor must attend a Zumba Instructor Training course, and then must keep their instructor license current through a variety of courses offered by the Zumba Academy, or by joining the Zumba? Instructor Network (ZIN?).?

Again, Zumba is a great way to stay fit while you work.

HEALTH COACHES

Health coaches are a popular profession, but the level of training isn?t clear cut. Not all organizations require coaches to be certified, according to LaRosa. He referred to Medifast as a company that trains their own coaches, yet he referenced a degree for health educators that may be necessary for many looking to seek this profession.

PERSONAL TRAINERS

Personal trainers are required to go through certification. There are a number of certification programs and options. As well, some gyms require more than just the certification and may also require college degrees in the field.

Trainer?Kalene Smith, ACE, CPT, owner at GoTimeTraining.com, gave some great insight into her career and those interested in becoming a personal trainer. Outside of the skills, Smith explains that training isn?t for the shy or timid.

?If you are that person who just likes to workout but doesn?t want to interact with others, personal training might not be your first pick.?

She explained that knowing how to take someone through an effective workout is just part of the game, and being able to really connect is very important in her career. ?People invest a lot of money in personal training and aside from a good workout, most clients are looking for someone to confide in, share their daily problems/frustrations, and sometimes they are looking for a shoulder to cry on,? Smith explained. The job requires catering to clients around the clock, according to Smith, as they need support with mental struggles, nutrition, motivation, and consistency. ?Personal training really is so much more than the one hour in the gym.?

Finally, Smith raised the point that you have to walk the walk in the training industry. ?A personal trainer needs to be a role model for their business/product, so make sure you?re in shape and live a healthy lifestyle ? nobody wants a trainer who is out of shape and doesn?t practice what they preach.?

All of these professions seem to be booming this year. Not all fitness trends last, and when considering a new career consider longevity, too. LaRosa feels a career as a registered dietitian would have the most job security.

He said, ?They don?t just deal with weight loss and can work in private practice, for health clubs, hospitals, diet companies, corporate wellness programs, etc.?

Is this the year you make fitness your business?

Self Improvement Strategies That Will Work For You | Set Yourself ...

It can be quite difficult to begin any personal development plan. There are so many attributes that make up your personality; which one do you decide to improve first? The following paragraphs will give you the direction you need to achieve the personal development you have always wanted. You will find numerous tips to help you reach your self improvement goals.

Do not shop because you are bored. If you practice something you like instead of shopping, you will not spend a lot of money and get into debt.

TIP! Do away with unneeded aggravation in your life. When something happens try not to go overboard and over-react.

One key to improving your lifestyle through personal development is to set goals that are reasonable. Take your weaknesses and focus on eliminating them and your self-esteem will rise.

Ask other people about their accomplishments instead of bragging about your own. You will be amazed to hear some of the wonderful and interesting things the people around you have done in their lives, and you will earn new respect for them by understanding their true character.

TIP! A great listener can be just as valuable as a proficient speaker. This is particularly true if you want to improve yourself.

Always try do do the best you can at whatever you do. Passion leads to greatness, so be sure to be passionate. It is easier to make the changes that mean the most to you, even if you aren?t the best. Try to boost your worth in your field of work, and enjoy the benefits your self-esteem will get from it.

Do you abuse alcohol? Is smoking or anything else harming your body? The body is a source of great wonder and is vital to our life, as such respect is what it deserves. Improve your life by eliminating unhealthy habits. Take a hard look at your daily life and find things that could benefit from a positive restructuring.

TIP! Many people struggle with personal development because their goals are difficult to figure out or just too vague. Set a clear, well-defined goal for yourself.

Keep in mind the well-known saying that you can?t please everybody all of the time. Your main concern should be yourself. You are responsible for making yourself happy. While it is important to remember this, you shouldn?t step on other people. If you are true to yourself and stick to your morals, you will end up happier on your path to self improvement.

Read good articles about personal development. A good personal development book can give you great advice and ideas that can change your life. Before you pick a book, read the reviews to make sure that it is worthwhile because some personal development books are better than others.

TIP! If you notice that you are consistently failing to meet your goals and live up to expectations, you should attempt to diagnose the probable causes. Look for stories of other people who have successfully achieved goals similar to your own, then compare your approaches.

Determine what kinds of things are getting in the way of you being successful. This is hard to do for a lot of people. Having the ability to identify weakness is very important and can help us to make positive changes in our lives. If you get rid of the things that might stand in your way, you can find the way to clear your path.

Pick out what you wish to do in life and go do it. Sitting and thinking about the life you want will not get you that life. Fulfill your dreams and make what you desire a reality.

TIP! You will be healthier and you will go further than you ever thought possible. When you are healthy, you feel better and have more energy.

Stay organized and keep up with how you are doing. When you can break down your goals, it becomes much easier to achieve them. Keep a daily journal on your goals and their progress, so that you know where you stand at all times.

One of the most basic requirements for your effective personal development is to willingly choose to change who you are. If you want to change and grow, accept it, and do it.

TIP! Use your time efficiently so you can get more done in a shorter amount of time. Something you can do is to increase the amount of short breaks you take throughout the workday.

Take a notebook around with you to jot ideas in. Paper is an old fashioned way to record notes, but it never runs out of battery power. Write your thoughts down when they occur, and then you can refer back to them later when the time is right.

Taking occasional risks, on a small level, can help you lead a happier life! Many people wind up feeling unfulfilled because they don?t want to risk failing or being rejected. When you take a risk, you are showing yourself that you have courage, which is important to finding happiness.

TIP! By using love, you can re-energize your faith and get closer to your personal development goals. They stem from one another; you must have love to have faith.

Before you say anything you may regret, count to ten. Breath deeply and think calm, peaceful thoughts. Calm yourself in order to avoid saying things you will later regret.

Take a notebook around with you to jot ideas in. Carrying a small notepad with you everywhere can be a great idea. Write your thoughts down when they occur, and then you can refer back to them later when the time is right.

TIP! As hard as it may seem, you must eliminate worry from your life. When you worry, you create a made-up situation inside of your mind that hasn?t yet happened, and in all likelihood, probably never will.

Therapy is indicated if you feel you cannot deal with your problems. While self-help books help to a certain degree, seeing a therapist has more personalized substance to it. Talking can be the motivation that some need in order to be successful. Books can?t talk back like a trained professional, after all.

We all make mistakes which includes making poor food choices once in a while. Try to do better next time, and don?t worry about that cheesecake you had last night. Today is a new day.

TIP! You can?t please all of the people, and there?s no use in trying. Please yourself first! This means that you are accountable for your satisfaction with life, not that you should sacrifice other people?s happiness for the sake of your own.

Humility is essential to your success. Compared to the immense universe we are really very small. It is impossible to know everything. We can all learn and grow. Remember this and stay open for new chances to learn. When you go into something with a unbiased mind, you can learn a lot from people.

Are you having problems meeting someone that is right for you? You should consider using the Internet. There have been quite a few couples these days that have met on the web. It is possible that certain someone is looking for you. Each has pros and cons.

TIP! How healthy your body is, affects how healthy your mind is. Partake in regular exercise and stick to a nutritious diet.

All people are susceptible to food temptations. Admit your poor choices, and move on with your life.

An extremely important key to personal development is knowing what you want to do with your life. Having long-term goals is great, because you could have a big change in your perspective.

TIP! Being healthy will allow you to focus on other areas of your personal development. When your body communicates a need such as hunger, pain or thirst, it is important that you address it as soon as possible.

Make an honest effort to become more organized. If you are able to get your life organized and keep it that way, you will see a real boost to your self-confidence. In addition, you won?t stress out anymore from the messes. There is something very calming about knowing that everything is in its place.

Without taking care of yourself, you will be unable to care for others. Whatever point you may be at on your journey, it is important to properly care for yourself.

TIP! Read books that promote your sense of well-being. Some people see it spiritually, whereas others just find it inspirationally.

As you can see, self improvement is simpler than it looks. By breaking your personal development process into small, manageable goals, you?ll find yourself closer to your goals by the end of every day. You?ll be able to practice what you?re seeking to adopt as habit, and you?ll increase your own morale to continue. These tips are only a springboard, it?s up to you to build a better life.

You should always strive to be the best in your area. When you are looking for ways to become a better person, follow your passions. You can?t be the best at everything, but you can inspire people in the same field as you. By increasing your value within your field of study or work, you can enjoy benefits including higher self-esteem.

Humbled by the flurry of internet success in the last three years.
