Here’s an interesting case of scientific research backtracking on a long held view about nutrition. Some things to think about are why science can do so much research to confirm a belief that turns out to be wrong. This article discusses various ways in which scientists come to conclusions including animal testing. What’s also interesting to consider is the role of intuition in belief. Because the plaque that builds up on your arteries is partially composed of cholesterol, it’s intuitively believable that cholesterol in your diet would be bad for you. Even though these warnings about cholesterol will be rescinded, people’s long held beliefs will not change so quickly.
