Many of us were never taught what eating healthy is. Children learn their eating habits from their parents. It is a learned behavior. It is not a chore. It’s not yucky. It doesn’t mean taking vitamins, or supplements. (If you have to take those every day it means that you are eating wrong.)
We as a culture have gone so far away from eating right that we have forgotten how. Most individuals who want to eat right feel the need to research it so that they know what to do. Now, if the culture around you has not taught you how to prepare foods like this then research may be needed. There are thousands of diets out there that will tell you what and how to eat. All of them seem to be backed by scientific research and all of them will probably be proven and disproven multiple times over the next few years. I recommend moderation in your diet. I have found, when you ask people how to eat better they already know. They’ll tell you that they should be eating less and what they should be eating is more vegetables and fresh food not processed or fast food. The principle is that basic.
Eating right will help reduce our risk of cancer, diabetes, heart disease, and a host of other diseases. If we teach our children this habit then in a few generations these diseases could actually become rare rather than the most common diseases in our country.
