So what are some biases that affect nutrition that aren't related to nutrition? I think we need to realize these biases, especially in ourselves, and Beware of them in others.
Personal taste. Some people just really like eating meat, fat, sugar, bread, etc. Studies are going to have an uphill battle convincing people to accept evidences that seem wholly unpalatable.
Environmental concerns. There are a lot of people that push non-meat diets for reasons that have nothing to do with nutrition, but because they believe that eating meat hurts the environment. This should be completely unrelated to nutrition.
Ethical concerns about eating animals. There seem to be some people that push plant-based diets, or vegan or vegetarian diets, due to the fact that they think that eating animals is morally wrong. This should be completely unrelated to nutrition.
What else am I missing??
Answer
Culture is unavoidable. I love eating from other countries/cultures but sometimes the texture or color or flavors are not to my taste. I remember when a babysitter gave my little brother yoghurt, which I’d never seen. I thought it was disgusting. I can’t imagine eating bugs, but some seafood is not far from them in looks.I don’t think eating vegan is in my future even though I agree we eat too much red meat. Moving away from grain feeding cows would be good for us, and them, and the environment.More vegetables always.
