Document Summary
Chapter 14: nutrients involved in blood health: trace minerals. Erythrocytes (red blood cells: transports oxygen. Plasma (fluid portion: blood volume, iron. Blood health: transports o2 and co2 in the hemoglobin, storage of o2 in the myoglobin. Heme (animal products: beef, poultry, shellfish. Non-heme (plant based sources: the darker shade of green vegetable means the more iron it contains, mushrooms, legumes, enriched grain products. Enhancers: vitamin c, low iron stored in small intestine, mfp factor (meat, fish, poultry)- heme iron. Inhibiters: foods high in fiber (phytates, soy protein, high calcium intake. Ferrous is best absorbed as an iron supplement. Gi tract distress from too much: zinc. Compounds that prevent free radicals damage by: donating electrons to fr or destroying the fr. Antioxidant activity: donates electrons to free radicals. Antioxidant activity: donates electrons to free radicals, decreased ldl oxidation. Excess amount in blood can cause plaque formation which can lead to atherosclerosis. Oxidation of ldl increases cholesterol buildup in arteries.
