Nutrients Chemical substances in food that helps maintain the body Some supply energy, while others repair and build tissue You need over 50 nutrients for good health No food provides all the nutrients needed for the body. That is why a VARIED diet is so important Types of Nutrients Protein Carbohydrates Fats Vitamins Minerals Water

Proteins Functions: Sources: How much is needed? 20% of total calories Protein is found in EVERY cell Provides amino acids which are essential for growth, maintenance and repair of tissue Regulates body processes (fluid balance) Can be used for energy if carbohydrates and fat are not available Sources: 20 essential amino acids 9 have to come from food (essential amino acids) Complete protein Examples: Meat, eggs and dairy Incomplete protein Legumes, grains and vegetables Must be made complete or body can’t use it How much is needed? 20% of total calories Best Choices: lean protein (chicken, salmon, turkey, )

Carbohydrates Functions: Sources: How much is needed? Simple Carbs: look for “ose” to identify hidden sugars! Glucose, Fructose, Lactose, Sucrose Complex Carbs: Starch, Glycogen, Fiber Functions: Primary source for the body’s energy Helps digest fat Used for growth and maintenance Rich in fiber help prevent cancer and intestinal problems Sources: Vegetables, Pasta, Seeds, Nuts, Fruit, Legumes (peas, beans) How much is needed? 55-65% of your calories should come from carbohydrates (mainly complex)

Fats Best Choices: lean protein (chicken, salmon, turkey, ) Functions: Provide energy Carry fat soluble vitamins Needed for healthy skin Provide protection to organs Help regulate body temperature Sources: Visible sources (accounts for 40% of fat calories consumed) Butter/margarine Salad dressings Oils and shortening Invisible sources (accounts for 60% of fat calories consumed) Eggs, cream baked products, avocados How much is needed? No more than 15% of daily calories…..CHOOSE MONO AND UNSATURATED FAT SOURCES Best Choices: lean protein (chicken, salmon, turkey, ) SATURATED (animal based: cheese, butter, etc) and TRANS FAT( used during manufacturing process, in lots of processed types of foods, crackers, cookies, etc. ELIMINATE THESE )

Fat also… Provides protection to organs Helps to regulate body temperature Regulate certain hormones Coating on nerves and the membranes that surround body cells Adds taste and texture to foods Helps you feel full for several hours after you eat

Fat soluble vitamins A,D,E,K stored in fat in the body A for vision D comes from sun needed for bones E found in fatty food is an antioxidant K needed for clotting blood

Minerals Chemical elements that are needed for certain body processes, such as enzyme activity and bone formation Calcium Chromium Copper Fluoride Iodine Iron Magnesium Potassium Phosphorus Selenium Sodium Sulfur Zinc

Water Soluble Vitamins Contain carbon and are needed in small amounts to maintain health and allow growth B vitamins – use for cell metabolism & energy Folate – especially important during pregnancy Biotin – helps metabolize enzymes C vitamins – helps produce collagen which repairs skin, bones and muscle, also helps the immune system function properly

Water About 60% of your body Need about 2 ½ quarts (8 ½ cups) per day Some water comes from food Prevents Dehydration – Warning Signs Thirst Headache Fatigue Loss of appetite Dry eyes/mouth Dark urine color Nausea Difficulty concentrating Confusion Disorientation Can cause death

Calories Units of energy 1 calorie = the amount of energy it takes to raise the temperature of 1 gram of water 1 degree C Carbohydrates 1 gram = 4 calories Fats 1 gram = 9 calories Protein
