1. Foods You Don’t LikeIf your current diet involves regularly eating food that you don’t like, you’re probably not going to be following that diet for very long. If a particular food doesn’t taste good, there’s no rule that says you have to eat it. Yes, it may very well have a number of nutritional benefits. But there are probably many other foods out there that provide the exact same benefits. There’s no need to keep eating a certain food you hate just because you’ve been told it’s “good” for you.
