Foods that Fight
This principle is very simple and easy to implement. It is likely the very first health change I introduced to my partner a number of years ago. She started to follow it and once she did anytime she deviated from it she really felt the negative effects of combining foods that fight. To test the truth of this nutritional principle all you have to do is experiment on yourself by following it for 14 days. Afterward return to how you normally have eaten and take note of how you feel.
