The Most Common Protein Mistakes Young Athletes Make

Protein is a hot topic among young athletes. Just the other day a mom emailed me and asked, “What do you think about {specific protein supplement}? My son wants to take it to bulk up.”

Other parents ask me how much protein their young athlete needs, which foods are the best sources of protein, or they complain they can’t get their athlete to eat it.

In the world of sports, protein has a magical aura. Some young athletes believe protein is the nutrient they cannot live without, and the one that should be maximized at all costs.

Don’t get me wrong. Protein is important to the young athlete, but it isn’t as enchanting as its reputation may lead you to believe.

All nutrients matter. For the swimmer who is growing, I could argue that carbs, protein and fat are all important. Eating too much of one nutrient or too little of another doesn’t work in the long run for athletic performance, and may even have some drawbacks.

Here are the most common mistakes I see young athletes make with protein:

1. Not enough protein in the diet

Picky eaters, dieters, and vegetarians—I am talking to you. If you are picky about protein foods like meat or beans, are prone to dieting, or are a vegetarian who shies away from plant sources of protein (read: beans and tofu), you may be at risk for low protein intake. Too little protein can compromise growth and development, impair performance and recovery, and place the young athlete at a higher risk for illness.

2. Add too much protein to the diet

Many young athletes who want to bulk up look to adding extra protein to their diet. A driving force behind this is the belief that extra protein will translate to more muscle.

It doesn’t.

Exercise, weight training and a healthy diet are what help young athletes gain muscle strength and mass. For younger children, muscles don’t bulk up, but they do get stronger. It isn’t until the teen years, when hormone levels peak that muscles start to get larger.

When protein is overdone, it becomes a calorie source. Too many calories may end up causing unwanted weight gain. Excess protein can also be a danger to young athletes, causing dehydration and taxing the kidneys, in some cases.

3. Choose fatty sources of protein

Have a hankering for fried chicken, Buffalo wings, or even bacon? While you might be justifying these foods as a protein source, the reality is they also offer a hefty dose of fat (and sometimes very little protein). Extra fat may mean extra calories and potentially some unhealthy fats (read: saturated and trans-fat). Instead, choose lean sources of protein most of the time.

4. Use protein supplements instead of food

Research tells us that young athletes generally don’t need extra protein. In fact, they get two to three times their protein requirements simply from eating food, and without even thinking about it.

Just like eating too many high protein foods, adding protein supplements to the diet of a young athlete may lead to unwanted weight gain, dehydration and a toll on the kidneys and liver.

One of my teen volleyball clients couldn’t understand why she had gained weight over the summer. She had added a protein shake in the morning and afternoon to her regular diet on the advice of her fitness trainer. The extra protein shakes tipped the calorie balance to the high side, which resulted in weight gain. She, like many young athletes, didn’t realize that adding protein to her diet also meant adding calories.

5. Unevenly distribute protein throughout the day

I call this a protein binge, and it looks like this: no protein at breakfast, a little bit at lunch, and a lot at dinner. This isn’t an effective way to use protein in a sports diet. Under normal conditions, the body builds and repairs tissue constantly. If you distribute protein evenly throughout the day (some at all three meals and with snacks), your body will get a steady supply of protein so the job of building and repairing tissue and muscle can happen most effectively.

What’s the biggest protein mistake you see young athletes make?

A lot of nutritionists are rethinking their views on fat, saying certain kinds of fat are not so bad. Any thoughts?

Yes, the idea that saturated fat is bad is dying a painful death.

Jill Castle, MS, RDN

Certain types of saturated fat (from animal sources), particularly dairy sources, are being highlighted as healthier than we thought–more research is needed, though. Best bets: plant fats, ie, vegetable oil, canola oil, olive oil, olives, avocado, and nuts.

Thanks Jill for this excellent article! Really appreciate it as it is a constant struggle as a registered dietitian and a swim parent to get coaches, parents, and athletes to understand this. With the heavy marketing and billion dollar supplement industry it continues to be a challenge but your article is perfect! Thanks!

Jill Castle, MS, RDN

You’re welcome! I could write a whole other article on the supplement industry!! Check out my book, I devote a whole chapter to supplements, focusing specifically on what information and research is available about the young athlete (under 18).

Eating bacon on Sunday Morning… Does it contain a lot of fat compared to protein?

Jill Castle, MS, RDN

I’d say yes, more fat than protein. However, if you pair it with eggs, you can get your protein there. 🙂
