Right and people are always looking for a quick fix and "just a pill to take". My understanding is that how nutrition affects the body is a poorly understood complex mechanism and isn't as simple as all fat is bad or all carbs are bad or red meat is poison. Keeping a diversified diet that is rich in real food and very little processed food is a good thing. Exercising is a good thing. Beyond that it seems like micro-optimizations with very little benefit.
