Today's guest post is by our office's own Rob Lazzinnaro who will be reviewing Jill Castle's Eat Like a Champion (which she sent me for review).I work with families on a daily basis who are troubleshooting around how to provide proper sport nutrition for their kids - kids who are often also faced with weight issues. So when I was given the opportunity to review Eat Like a Champion by Registered Dietitian Jill Castle, I jumped on the chance as I'm also a big fan of Jill Castle's previous co-authored book Fearless Feeding: How to Raise Healthy Eaters from High Chair to High School, and currently enjoy following her blog Just The Right Byte.
Jill’s new book, Eat like a Champion, focuses on recommended dietary approaches for young athletes. From high level athletes to gym class, the book is meant to be resource for any child that engages in regular physical activity. The question of what to feed their active kids is one I hear often in my office from parents regarding nutrition around sports, but parents soon learn that it is more complex than just the “what.” In her new book Jill Castle does dedicate a well deserved portion of the book to the “what” but also tackles the difficult food environment for athletes and how paying attention to a multitude of factors around eating can ingrain healthy habits in your young athlete for a life time.
The book is divided into ten chapters:
- The Growing Athlete Body and Brain
- The Starting Lineup: Major Nutrients
- The Second String: Vitamins and Minerals
- The Relief Pitcher: Fluids and Hydration
- Game Plan - One, Two, Three Meals
- Take a Time Out - Top Off with Snacks
- Foul Play - Supplements and Performance Aids
- Getting Off the Bench - Healing the Body with Food
- The Special Diet Dilemma
- Changing the Youth Sports Nutrition Landscape
Matching Calories for Growth and Sport
Every person who picks up this book will have a child with different needs and energy requirements - there is no one size fits all when it comes to eating. The key is not to become overly obsessed with these numbers but hopefully use them as rough guidelines to help assess whether you're offering your child too little or too much - peace of mind really. Of course, the parent would have to loosely track the child's intake for 4-5 consecutive days (hopefully w/o the child knowing) to see where they are landing. The author also includes a useful table for changes in calorie requirements depending on the sport played.
Busting the Myth about Carbohydrates
Apologies Paleo adherents and wheat haters but this chapter focuses on evidence, which points to carbs not being inherently evil and how they can be a joyful part of our dietary lives. An excellent overview of choose most often carbs compared to choose less often is detailed here as well; aka, not all carbs are created equal. Finally, in children with high activity levels, carbohydrates can become vital for peak performance, as children are limited in their ability to store carbohydrates.
Foul Play - Supplements and performance aids
This section is a vital resource for parents wondering about the safety and efficacy of performance supplements. Hint: most supplements are not worth anyones time or money; and many are detrimental not beneficial to health. Good reference charts on supplements provided here.
Diets, Dieting and the Young athlete
The most important chapter in this book. Young athletes can set themselves up for a lifetime of dieting, body image issues, and eating disorders with the wrong information and ideas about ideal weight for sport and how weight is managed. In this chapter the author helps bust myths about the efficacy of popular diets and presents, more importantly, the dangers that come with a dieting mentality
Changing the Youth Sports Nutrition Landscape
I was absolutely thrilled this chapter was in the book because the field has become the tipping point around the normalization of junk food. We have all had the after game Slurpee, ice cream, or other frozen treat, and it was great when those items were indeed treats that we had less often. Nowadays when kids are playing sports 2-5 days a week and being offered treats after every game (these on top of the treats likely offered for every other event however small in their daily lives) they have become excessive. Point is, the exercise = food reward is not a positive behaviour we should be teaching our kids.
And there are also a few themes in the book that I struggled with:
1. Chocolate Milk
Throughout the book chocolate milk is recommended as a high protein healthful snack. Regardless of whether or not your children are elite athletes or just regular organized sport lovers, chocolate milk is a treat, and I fear that providing it to a child under the guise of it being a good fuel for sport may provide the wrong message. p.s An 8 oz glass of chocolate milk has 12 g or 3 tsp of added sugar - a 500ml carton - 25g or ~6 tsp added sugar.
2. The Focus on Micronutrients
I feel the chapters around the vitamins and minerals might be useful for an RD, but I wonder whether or not they'll provide much utility to the average family or child athlete.
3. Protein Supplements
There is some vilification of protein supplementation. Truth be told, I am not a strong advocate of protein supplementation, but there is no evidence that I'm aware of that would suggest unadulterated protein powders are unsafe for children to use, e.g. to balance a fruit smoothie with. If said protein powder is adulterated and has a sketchy wt.loss or endurance supplement added to it, then yes, please steer clear.
In summary, Jill Castle has once again provided a valuable resource on child nutrition, whether you are reading it as a health professional or as a curious parent. The book lays down a solid resource on what to eat and how to fuel yourself within varying degrees of activity. However where I found the most value was in the closer look at how we eat, supplementing safely, the dangers of dieting, and the treacherous food environment that all child athletes must face these days. Just in time for the school year, go Dillon Panthers! ;)
