Achieving a healthy diet is popularly misperceived as being attainable by eating 'healthy foods'. Many people[attribution needed] falsely believe that there are 'good' and 'bad' foods; they develop bad diets because they think that abundant eating of foods they consider 'healthy' will create a healthy diet. However, this is far from the truth.
Although a healthy diet is based upon nutrition, people eat foods and not nutrients; as few people know which foods supply which nutrients, allowing people to self-regulate their diets means that they run the obvious risk of deficiency. Due to past difficulties of educating people about nutrient intake, governments have opted to counsel on what foods to eat rather than on what nutrients to ingest.
