Dietary goal = increase intake of indigestible cho. Two essential fatty acids, alpha-linoleic (n-3) and linoleic (n-6) Key roles as precursors for signaling molecules, structural role in membranes, etc. Goal is to decrease intake of total fat (especially sfa and trans) and increase of. Provides aas for protein synthesis and other areas of metabolism. 21 proteinogenic aas (used to make protein) 22 aas in reality (but pyrrolysine is used by bacteria, not humans) Histidine was the last aa to be added to the essential list.
