In addition to recommendations about what to eat and drink, and when to eat and drink it, Nutrition for Cyclists contains a good deal of information about why these recommendations make sense based on how the body works. This information is designed to give the rider a better understanding of why their body is doing what it’s doing. The more you understand about how food and drink fuel your ride, the better you will be at figuring out what the problem is when things go wrong. The better you get at figuring out what went wrong, the better you’ll get at fixing it during the ride and making sure it doesn't happen again.
The information in Nutrition for Cyclists is based on research published in peer-reviewed scientific journals in the fields of human physiology, and nutrition and exercise science. The internet is awash with assertions, recommendations, and unsubstantiated claims about exercise nutrition. Some of this advice is supported by sound research. Much of it, including a number of widely cited and uncritically accepted ideas, is not. Limiting our focus to information that is well supported by sound research does not mean that everything in Nutrition for Cyclists is “right” or “true”. It means that this information is the best we have based on the current state of scientific research on exercise nutrition.
While Nutrition for Cyclists is directed toward bicycle riders, the nutritional information in the book will be useful to people engaged in athletic endurance activities of any kind.
