body 0 give us energy 0 Food sources of carbohydrates 0 Grains fruit starchy vegetables legumes milk 0 How many kcalgram o 4 kcalgram What is the AMDR 0 4565 0 Be able to calculate recommended intake levels 0 2000 kcals x 50 0 Names composition and food sources of the o Monosaccharides don39t require digestion in simplest form Glucose Fructose Galactose o the disaccharides simple sucrose table sugar glucosefructose lactose milk sugar glucosegalactose maltose o the oligosaccharides complex 0 the polysaccharides complex Starch from plant sources Glycogen from animal sources Cellulose indigestible from plant cell wall 0 The difference between a simple carbohydrate and a complex carbohydrate 0 Simple made of just 1 or 2 sugar molecules quickest source of energy easily digestible ie sugar candy soft drinks 0 Complex sugar molecules strung together rich in fiber found in whole plant foods a lot le whole grains green vegetables ect The difference between a refined grain and a whole grain o Refined grain after the bran amp germ are removed longer shelf life 0 Whole grain contains bran sperm amp endosperm very nutritious The difference between lactose intolerance and a milk allergy o Lactose intolerance not having enough of the enzyme lactase needed to break down lactose 0 Milk allergy allergic reaction to protein in milk What foods could a person consume with lactose intolerance vs a milk allergy o Lactose intolerance small amounts of dairy dairy free foods 0 Milk allergy avoid all dairy casein whey lactulose lactalbumin ghee Know the difference between starch glycogen including where is it stored amp what is does for the body and cellulose as well as food sources of each 0 Starch a carb rice potatoes wheat power brain give you energy digested into blood

hydrogenated oils on ingredient list 0 raise LDL bad amp lower HDL good cholesterol levels increases risk of developing heart diseasestroke risk of developing type 2 diabetes 0 fried foods baked goods margarines spreads frozen pizza 0 made from turning liquid oils into solid fats Know the functions of cholesterol in the body and food sources 0 Cell walls need it to produce hormones vitamin D amp bile acids that help digest fat 0 Animal products meat amp dairy eggs beef chicken cheese burgers Know the relationship between fatty acid intake amp risk of CVD good vs bad fats o Decrease risk of heart problemsheart disease 0 Fish oils increase risk of mercury contamination Be able to explain why a lowfat food might not be healthier than a fullfat food 0 Some could have a lot of additives
