Deficiency occurs when fat intake falls below 10% of daily nutrition. Various types of fatty ac-ids have significance for health and for the incidence of disease and are referred to in dietary guidelines. Linoleic acid and arachidonic acid are important for metabolic processes but are man-ufactured by the body when linoleic acid is available. Most animal fats have high proportions of saturated fatty acids, whereas vegetable fats have higher amounts of unsaturated and polyun-saturated fatty acids.
