Be careful about the “facts” shared on the Internet that are not based on real science. Nutrition advice can drive sales for a “nutritionist” touting a diet or detox or supplements but waste your money or actually be unsafe. Many states don’t require formal training for nutritionists, so that title can be used freely. Always check credentials to make sure they are registered dietitians or physicians. Even then, it is a good idea to corroborate their findings or recommendations with others in their field.
