A few lesson ideas A Macronutrient We eat it in (relatively) large amounts Provides energy (that means Calories) Contains nitrogen Important tissue in the body Molecules (with nitrogen) that have important functions in the body Carriers MUSCLES Enzymes that make reactions happen Forms the basis of bones and teeth Antibodies and Immune System Give structure to some foods Provides calories Gives a feeling of satiety, so that eating can stop Tends to even out blood sugar Proteins in Foods What Does A Protein Look Like? Starts as strings of amino acids 20 different ones are used 9 need to be provided by the diet Strings are twisted, folded, held together so that protein has a shape Shapes determine what the protein is able to do Meats, fish, poultry 7 grams / ounce Dairy Products 8 grams / cup milk Eggs 7 grams / egg Legumes 15 grams / cup Grains 3 grams / ounce Seeds, nuts, and most vegetables also have some We need to get 9 of the 20 amino acids from our food Animal proteins have all of them So does soy Other sources are low in one or two Digestibility also counts That’s how easily the body can get to those amino acids Fiber and other plant substances in nonanimal foods decrease digestibility Fiber—both Soluble and insoluble Saturated Fat Cholesterol Total Fat (Unless fat-free, it’s all there) Other Nutrients (varies, too) B vitamins (Not B12, but Folate) grams per day 60 50 40 30 20 10 0 1-3 Years 4-8 Years 9-13 Years Girls, 14-18 Boys, 14-18 Women, Men, 1919-70+ 70+ But, that assumes Calories are adequate And person is healthy And normal weight and height Another way to figure is to multiply weight in kilograms by 0.8 gm protein Or multiply weight in pounds by 0.4 gm protein And how much FOOD is that? A day’s food intake including 4-7 ounces of meat, fish or substitute and 2 cups of milk 28-49 g protein from meat, 16 g from milk, plus more from grains Daily Values aren’t given for foods unless they are meant for kids under 4.
