Novak Djokovic touts it. Some Olympic athletes tout it. It is a gluten-free diet. While it’s questionable as to whether he has celiac disease or may just have some gluten sensitivity (if he had celiac disease, I doubt he could have risen to the top of the tennis world while eating breads and pasta his whole life) Djokovic claims that switching to a gluten-free diet a while back improved his endurance and physical strength. He won 4 straight major tournaments after his gluten-free regimen. (Now, he’s lost in his last two majors plus the Olympics tennis competition).
Many athletes and people who don’t have celiac disease are trying gluten-free eating anyway, claiming it can improve energy levels, improve sleep quality, etc. Yet, there are warnings that simply going gluten-free without a health condition to warrant it, may not be good for you. Grain-based foods add fiber to the diet, something that may be missing in gluten-free. Fiber and grains help feed the gut’s beneficial bacteria, a basic need for helping drive proper digestion, nutrient absorption and immune function.There’s no strict rule on this. If you try gluten-free, just make sure you do so with a licensed nutritionist’s help, and be aware of what you’re giving up
