Adherence

Higher general nutrition knowledge is significantly associated with meeting fruit and vegetable intake recommendations and consuming a diet lower in fat.

Understanding nutrition guidelines is a strong predictor of eating healthier, but knowing the rules isn't enough to change your diet. To actually improve your intake of fruits, vegetables, and lower-fat foods, you need to go beyond just reading labels or guidelines and actively work on interpreting and applying that information in your daily life.
