2What Is Nutrition-Nutrient: A chemical substance in food that helps maintain the body.-Nutrition: The study of how your body uses the food that you eat.-Malnutrition: is the lack of the right proportions of nutrients over an extended period
3What is a Nutrient(A nutrient is a chemical substance in food that helps maintain the body.)Some provide energy. All help build cells and tissues, regulate bodily processes such as breathing. No single food supplies all the nutrients the body needs to function.Deficiency Disease: failure to meet your nutrient needs.
4The six Classifications of Nutrients VitaminsMineralsWaterProteinCarbohydratesFatsSugarsStarchesCellulose
5Carbohydrates The body’s chief source of energy Sugar Starches Fiber Simple CarbohydratesGlucose: BloodFructose: FruitGalactose: MilkSucroce: Table sugarStarchesComplex CarbohydratesFiber
6Fats Important energy source Lipid family which includes fats and oilsHydrogenation: adds hydrogen atoms to unsaturated fatty acids (liquid) turning them into more saturated solid fatsCrisco and margarine sticksCholesterol: fatlike substance found in every cell in the bodyImportant… found in skin tissue, produces hormonesTwo types: Dietary and Blood
7Fat MoleculesFats are large molecules made up of elements - Carbon, Hydrogen, OxygenFatty acids found in animal triglycerides are saturated onesFatty acids found in plant triglycerides are unsaturated ones ( exception - tropical oils)
8Proteins Provide energy, encourage growth and tissue repair Made up of small units called amino acids20 important to the human body: 9 your body can’t make and 11 it canComplete protein: animal foods and soyIncomplete proteins: plant foodsMust pair 2 foods together: beans and rice
10Vitamins Are complex organic substances Normal growth, maintenance, and reproductionYour body cannot produce all vitamins you can get those by eating a nutritious diet.Fat-soluble vitamins: carried in fatty parts of foods and dissolve in fats (body stores them in fat... build up can be dangerous)Water-soluble vitamins: dissolve in water (body does not store them)
11Fat-Soluble VitaminsVitamin AVitamin DVitamin EVitamin K
13MineralsIn addition to vitamins your body also needs 15 minerals that help regulate cell function and provide structure for cells. Major minerals, in terms of amount present, include calcium, phosphorus, and magnesium. In addition, your body needs smaller amounts of chromium, copper, fluoride, iodine, iron, manganese, molybdenum, selenium, zinc, chloride, potassium and sodium.Amounts needed for most of these minerals is quite small and excessive amounts can be toxic to your body.
14mineralsCalcium:A mineral important for strong teeth and bones and for muscle and nerve function. The major mineral constituent of bone.sources: milk and milk products, fish with bones that are eaten, turnip and mustard greens, tofu, almonds and broccoli.Chloride: A mineral that regulates body fluid volume, concentration and acid-base balance. Balance intertwined with that of sodiumChromium: A mineral important in regulating blood glucose. sources: brewer's yeast, whole grains and meatsCopper: A mineral that is important for nerve function, bone maintenance, growth, blood formation and utilization of glucose.sources: organ meats, sea foods, nuts and seedsFluoride: A mineral that is important to dental and bone health. Greatly improves resistance to cavititessources: fluoridated water, foods cooked in or containing fluoridated water, fish with bones that are eaten, and teaPhosphorus: A mineral essential to bone formation and maintenance, energy metabolism, nerve function and acid balance.sources: meat, poultry, fish, eggs, dairy products and cereal products.Potassium: A mineral that is essential for nerve function, muscle contraction and maintenance of normal blood pressure.sources: fruits and vegetables.
15mineralsIodine: A mineral essential for the production of thyroid hormones.sources: sea foods, iodized salt and foods containing iodized saltIron: A mineral that is an essential constituent of blood and muscle and important for the transport of oxygen. Certain groups can be at risk of having low iron levels. These include young children and early teens, women with heavy menses, women with multiple pregnancies, and people with conditions that cause internal bleeding, such as ulcers or intestinal diseases.sources: liver, red meat, egg yolk, legumes, whole or enriched grains and dark green vegetables.Magnesium: A mineral found mainly inside muscles, soft tissues and bone. It functions in many enzyme processes.sources: nuts, legumes, whole grains and green vegetablesManganese: A mineral that is important for growth, reproduction, formation of bone, and carbohydrate metabolism.sources: whole grains, fruits, vegetables and tea.Molybdenum: A mineral involved in many enzyme processes, nerve function and protein metabolism.sources: milk, beans, breads and cereals.
16MineralsSelenium: A mineral associated with antioxidant properties and fat metabolism. It has been claimed to help prevent cancer and cardiovascular diseasesources: seafoods and organ meats.Sodium: A mineral that regulates body fluid volume, concentration and acid-basesources: table salt (sodium chloride), foods processed with table salt, milk, milk products, eggs and seafoodsZinc: A mineral involved in wound healing, taste sensation, growth and sexual maturation and part of many enzymes regulating metabolismsources: meat, liver, eggs and seafood (oysters).
17WaterWater is your body's most important nutrient, is involved in every bodily function, and makes up % of your total body weight. Water helps you to maintain body temperature, metabolize body fat, aids in digestion, lubricates and cushions organs, transports nutrients, and flushes toxins from your body.Everyone should drink at least 64 ounces per day, and if you exercise or are overweight, even more. Your blood is approximately 90% water and is responsible for transporting nutrients and energy to muscles and for taking waste from tissues.
