Document Summary
Essential nutrient: nutrients that must come from diet; if they are absent from diet = death!!! Amino acids: make up proteins; there are essential and nonessential forms. Triacylglycerols: makes up fats :) (3 fa + glycerol) Pufa/mufa: fatty acids have double bonds; poly-unsaturated fatty acids (ex. Canola + soybean oil)/mono-unsaturated fatty acids (ex. olive oil) 2 pufas: linoleic acid (omega-6) + alpha-linolenic acid (omega-3) (*number refers to positioning of double bond) Long-chain omega-3 fatty acids: can be synthesized from alpha linoleic acid - dha (docosahexaenoic acid), epa (eicosapentaenoic acid) - multiple double bonds. Micronutrients: vitamins + minerals (micro = needed in small amounts) Fat soluble vitamins: adek (can be stored in liver and adipose tissue + not rapidly depleted by body) - months, toxic in excess. Water soluble vitamins: b & c (cannot be stored, rapidly depleted except b12) - weeks, no worries ya poop it out. High-fructose syrup - 1:1 mixture of glucose + fructose (often labelled as glucose/fructose)
