Why are fats & oils rated differently than the other foods in the store?
The model used to evaluate general foods and beverages would not differentiate the fats in a meaningful way as it does not include attributes such as monounsaturated fatty acids, and omega 3 fatty acids which distinguish the healthiest fats. It is recommended that intake be between 20% and 35% of total calories. Fats & oils are very calorie dense (typically about 100 calories per tablespoon) so only a few tablespoons a day is enough.
