Some people plan their eating based on the 'correct' amount t of carbs, fats and proteins and micro-nutrients - vitamins and minerals . Others, prefer to focus in eating good food without caring about what a label, if any, would say.
A good example, is the consumption of butter. Some would avoid it simply because it is high in saturated fats. While others would appreciate a good quality (minimally processed) butter regardless.
What sort of healthy eating you do or want to do? Nutrient-based or food-based?
