I am a big fan of Matt Fitzgerald's writing, have quite a few of his books. He doesn't jump on the bandwagon of every fad or trend that comes along in the endurance athletics world; he investigates for himself, and reports from that investigation and from his own experience. He just seems to me to be a real genuine person. His books and articles are very well written, understandable to interested athletes, and entertaining as well.
Matt wrote an article recently for Competitor.com entitled "The 10 Biggest Sports Nutrition Myths." REQUIRED READING for all my distance runners!!
Here is the list, but follow this link to read the article for yourself; Matt says it much better than I can.
The 10 Biggest Sports Nutrition Myths are:
1. Taking in simple sugars during exercise is bad.
2. There is an optimal macronutrient ratio.
3. It's necessary to carbo-load before races.
4. You should drink to completely prevent dehydration.
5. Eating more fat will increase your endurance.
6. Muscle cramps are caused by dehydration.
7. All sports drinks are the same.
8. Most runners eat enough carbohydrate.
9. Runners need to eat as carefully as non-runners.
10. Supplements are necessary for maximum performance.
Here are a few books Matt's written (or written with others) that I recommend runners to read. If you click on the book it will take you to Amazon.com where you can purchase the book.
