What are nutrients? �A substance that performs a job in your body Wet Pink Cars Move Very Fast (water, protein, carbs, minerals, vitamins, fats)
What do nutrients do? �Provide Energy �Build and Repair Body Cells �Regulate Body Process
From Food to Body �Our bodies digest food and nutrients are absorbed through the bloodstream. (6 nutrients, 6 steps of absorption) 1. 2. 3. 4. 5. 6. Mouth-break down begins Esophagus- carries to stomach Stomach- breaks down food chemically Sm. Intestines- absorbed into the bloodstream Liver- from bloodstream to cells Lg. Intestines- removes water, potassium and sodium, the rest is eliminated
Wet = WATER �Water carries nutrients �Regulates body temperature �Lost through breathing, sweat and waste �Source: juice, milk, soups and water �Boys need more than girls
Pink = PROTEIN �Build and repair cells for growth �Fight disease �Some energy �Excess stored as body fat �Complete Proteins- have 9 essential amino acids, found in animal products �Incomplete Proteins- lack essential amino acids, found in plants
Cars = CARBOHYDRATES �Main source of energy �Simple- sugars, quick energy, fruit & milk, added sugar �Complex- starch and fiber, prolonged energy, plant sources
Move = MINERALS �Body’s processes, cells, fluids, muscles, bones �Bones- calcium, phosphorus, magnesium �Osteoporosis- weakening of the bones due to loss of calcium �Need for calcium is highest during teen years �Anemia- not enough red blood cells to carry oxygen, feel tired and weak, need iron
Very = VITAMINS �Regulate body processes and help other nutrients work �Water soluble- dissolve in water B Vitamins and Vitamin C Folate is needed during pregnancy to prevent birth defects �Fat soluble- dissolve in fat (stores in fat and liver) Vitamins A D E and K
Fast = FATS � Provides energy, transports vitamins, slow digestion � Body makes fat from excess fat, carbs, protein � Insulates and cushions � Too much = risk of heart disease and health problems � Cholesterol- body makes enough for body processes, from animal products, too much = heart disease � Saturated- solid, from animals and tropical oils, raise cholesterol � Unsaturated- liquid, from vegetable oils, nuts, olives and avocados, lower cholesterol, fatty acids are good for your heart � Trans Fat- hydrogenated (processed) like margarine, raises cholesterol
