Eat Your Wheaties(?)



An article that just came out in the Journal of the International Society for Sports Nutrition touts the advantages of eating Wheaties after a workout, saying it helps the body recover from exercise better than a sports drink.

In their recent (May 14) article entitled Cereal and nonfat milk support muscle recovery following exercise, researchers from the Exercise Physiology and Metabolism Laboratory at The University of Texas at Austin examined the effects of eating cereal and (nonfat) milk or a sports drink immediately following exercise on the body's ability to make glycogen (muscle fuel) and protein (a building block for muscle growth).

In the experiment subjects either drank two 20-ounce bottles of a 6% carbohydrate sports drink or ate a bowl (73 grams) of Wheaties with 350 ml nonfat milk (and some additional water).

The subjects then exercised by riding stationary bicycles and blood and muscle tissue studies were performed before and after they ate/drank either the cereal and milk or the sports drink to analyze how well their muscles recovered from the exercise.

The authors concluded that their results "suggest that Cereal is as good as a commercially-available sports drink in initiating post-exercise muscle recovery." and went on to say the "readily available foods such as cereal and nonfat milk can provide postexercise supplementation and be used in lieu of a commercially-available sports drink after moderate exercise. Cereal and nonfat milk provide a less expensive whole food option as compared to sports drinks. It also provides easily digestible and quality protein in the milk, which could promote protein synthesis and training adaptations, unlike a carbohydrate sports drink. This is a potential option for individuals who refuel at home".


OK. I agree with all that they say, but let's take a closer look at the real-world implications.
While this may be an option for people who run/bike and finish their workout at home, not every basketball player is going to be that close to a cupboard and refrigerator when they're out on the court or at a tournament.

More importantly, the authors aren't really comparing eating cereal and milk to the "gold standard" recovery drinks that include protein (and not just carbohydrate-only drinks like in this study).
And what about just plain old chocolate milk?

To their credit, the authors admit that "Although muscle response during recovery to a carbohydrate-protein drink may be similar to that seen after whole-grain cereal and nonfat milk, we chose to compare a carbohydrate-only drink."

Why?

Because "Recreational athletes may be more familiar with carbohydrate drinks due to high product awareness and accessibility, and may not understand the benefit of added protein in post-exercise supplementation."

I think that's taking it a little out there, but it's understandable that a conclusion like this would be reached in a study that was supported by Wheaties and the General Mills Bell Institute of Health and Nutrition.

While this may be true for many recreational athletes, I hope that readers of this blog will know better and will understand the difference between sports drinks that rehydrate and "recovery drinks".

One other implication of using cereal and milk to refuel - it usually takes the stomach longer to process/digest solid foods like cereal than it does liquids. So think twice about eating cereal and milk if you don't have much time between games of a tournament, unless you don't mind cramping up on the court.

All that being said, I think that Wheaties and milk is an excellent option for breakfast (and late night snacks).

Breakfast of Champions? Absolutely.
The best Post-exercise recovery option? I'm not convinced.

P.S. - Congratulations to the 2008-2009 UNC Men's Basketball Team. I guess the Wheaties Box pictured above needs to be updated to 6-Time National Champions (5 men's and 1 women's).

Nutritional Supplement Use in the UK

Journal of the International Society of Sports Nutrition, December15, 2008

In an article published earlier this week in the Journal of the Internation Society of Sports Nutrition , researchers from Kingston University in London reported on nutritional supplement use among young (ages 12-21) elite athletes in the United Kingdom.


Athletes take supplements for different reasons: to improve their health, enhance their performance, round out their diet, and increase their energy.
One concern I have is that many young athletes take the wrong supplements, in the wrong amounts, at the wrong times.

In this study, young elite athletes most often reported taking (in descending order) energy drinks, vitamin C, multivitamins, whey protein, creatine, echinacea, caffeine, iron, ginseng, and melatonin. Often, though, they weren't able to correctly match their reason for taking a supplement with the supplement needed to reach their goal .


Take a look at the graph above.
When asked about the source of advice to take three of the most popular supplements (creatine, whey protein and energy drinks) most young athletes reported they took them without advice from others. While it's comforting to see that the second most reported source of advice was their coach, the coaches themselves, while well intentioned, might not be giving out correct advice.


What about health care provider's advice? Nutritionists were the 3rd most common source of advice (after NONE and coaches). Team doctors and general practitioners? Way behind even fellow athletes and friends.


This needs to change. Athletes, especially those who are still growing, need credible, reliable advice on ways to safely optimize their health and performance. Doctors are partly at fault, because most are not up to date with current evidence-based sports nutrition. Hopefully, health care professionals can work to translate the latest research results to the everyday player so that s/he can make informed decisions about what, and what not, to put into their bodies.

*********************************************************************
Looking more critically at the article, it's notable that the response rate (those who sent back their answers) was only 1/4 of the 1,674 athletes who received the questionnaire. For our interests, it's also important to know that basketball players were not studied here ("Game On"?) . I also don't know what constitutes "energy drinks" in the UK (are they hydration drinks, recovery drinks or something like Red Bull - ugh). I've asked the lead author to answer this last question. Will let you know when I do.

B*U*R*P


An Espn.com article last month described Derrick Favors (one of the top-ranked high school players in the country) as his team's "meal ticket" .

Unfortunately, he and his teammates were never taught what type of meals they should, and should not, eat before games.
The article describes what happened to him and his teammates before a state tournament game last year where they lost in the first round.
They "had a transportation issue before that first-round game. The bus was late by 90 minutes or so. The Hornets arrived about 30 minutes before tipoff, and perhaps worst of all, somebody -- a parent, a fan, nobody seems sure -- decided to try to help by buying dinner. Those bacon cheeseburgers were good."
Ah, if only they had read my post from last year ("You Are What You Eat"- August 2007) and gone to some of the websites about nutrition for basketball players, they would have known that you don't eat greasy bacon cheeseburgers any time before an important game or practice.
What you eat before games depends upon how long you have to digest the food. Carbohydrates are the best and most easily digested types of pre-game meals. A little protein can be added if you've got a while before gametime.
And the bacon cheesburgers?
"four players suffered cramping problems during the game, Favors landed in foul trouble, and the Hornets -- who averaged 83 points per game last season -- scored six points in the fourth quarter".
Moral of the story? You are (and might play like) what you eat.
Moral #2: Bacon cheesburgers should NEVER be (or be eaten by) your meal ticket.

The Big D


No, this post is not about Dallas.

It's not about defense either (although defense does win games).

It's about Vitamin D.


You know, the vitamin that's found in fish, eggs, and fortified milk.

The vitamin that may reduce your risk of osteoporosis.


Here's the news.

Last week, the American Academy of Pediatrics doubled the recommended dose of vitamin D for infants, children and adolescents from 200 IU (international units) to 400 IU.


If you can't get enough in your daily diet (and by spending 10+ minutes outside in the sunlight each day), then you should take a vitamin that has the new, increased amount in it.


But how is this going to help my crossover? My jumper?


It's not.


But it may decrease your risk for osteoporosis as an adult (women are 4 times more likely to develop brittle bones as men) and it may also help prevent infections, autoimmune diseases, cancer, and diabetes.

That should be a good enough reason for you to make sure you're getting enough of the Big D every day.

You Are What You Eat


A recent article by Nancy Clark got me to thinking about some of my favorite basketball nutrition articles and resources.

Here's a short list that I've also added to my link section (lower right hand corner of this blog) .

While these links provide good general information, none of it takes the place of having a sports dietitian work with you to optimize your nutrition.
