I’m not the biggest fan of fads in general, but health fads are more likely to tick me off. There are a number of people in the world with real and serious gluten intolerances. Then there’s a much larger number of others who think eliminating something from your diet will make it healthier. Substitute products or “fake foods” which emulate the presence of something that is not there are never better for you, and as alluded to in the article, most gluten substitutes have a higher glycemic index, which can have a negative impact on your metabolism and odds of developing diabetes later in life.
If you don’t have celiac disease, there’s no reason to go gluten-free. If you do have celiac disease, eating whole foods without gluten (like pretty much every vegetable and fruit we cultivate, not to mention all meat ever) will be healthier than “gluten-free” fake bread.
