The label on a bag of salt-free pretzels indicates that their chips are "low-fat." this means the pretzels provide 3 gram(s) of fat or less per serving.
Low-fat diets are diets in which the fats are reduced. Low-fat diets are produced in order to prevent diseases such as obesity and heart diseases. Food manufacturers usually use nutrient claims such as '‘low fat’' to indicate the nutritional value of their products. A ‘low fat’ food contains not more than 3g of fat per 100g of food (for solids) and not more than 1.5g fat per 100g (for liquids).
