It is understandable that many people are confused or cynical when they hear about a new study that contradicts what they thought was accepted science. One suggestion would be to look at nutritional guidelines on websites of organizations such as the American Heart Association or the American Diabetes Association. Those guidelines tend to be very carefully discussed and research is carefully evaluated, and the guidelines are a bit on the conservative side, which I think makes sense.
