1. Nutrition By: Sabrina and Elizabeth Grade 8

2. Table of Content • Slide # … • 1- tittle page • 2- table of content • 3- carbohydrates • 4- carbohydrates • 5- fats • 6- fats • 7- protein • 8- protein • 9- fibre • 10- fibre • 11- bibliography

3. Carbohydrates • Energy source for body • 2 types : • Complex (starches) • Simple (sugars) • May cause health problems (e.g. diabetes, and heart disease) • Releases insulin, sugar can be stored for energy

4. Carbohydrates • Complex • helps you feel full • carbohydrate foods are better choices than others • Simple • contain vitamins • found in refined sugars

5. Fats • compound comprised of glycerol • Energy source-muscles • 3 types - Unsaturated fats (oil) • Saturated fats (dairy) • Trans fats(baked goods) • include nuts, oil, butter, and meats • Kids need fat so the brain and nervous system develop • fuel the body and help absorb some vitamins

6. Fats • Unsaturated • good for heart health • in olive oil, peanut oil, canola oil, albacore tuna, and salmon • Saturated • used in commercial baked goods • can raise blood cholesterol levels • Trans • listed on the food label • raise cholesterol and increase risk of heart desise

7. Protein • builds up the tissues in your body • make hemoglobin that carries oxygen to every part of body • beef, poultry, fish, eggs, dairy products, nuts, seeds, and legumes • amino acids break down protein • Only 1 type

8. Protein • body will grab protein from each meal. • maintain muscles, bones, blood, and body organs • FUN FACT! • To figure out your protein needs, multiply your weight in pounds times 0.5 or you can just take your weight and divide by 2

9. Fibre • found in oats, citrus fruits, apples, barley, psyllium, flax seeds and beans. • 3 types - Soluble (dissolve water) - Insoluble (moves material to colon) - Lignin (phenols chemicals) • helps the easy elimination of waste from body • Made up of complex carbohydrates • Reduces risk of bowel problems

10. Fibre • Soluble • help lower blood cholesterol levels • helps to control blood sugar • Insoluble • helps in weight control • No calories in fibre • Lignin • There aren't calories in fibre • branches of chemicals called phenols

11. Minerals Calcium, Iron, Magnesium ,Phosphorus, Potassium Selenium, Sodium, Zinc chemical elements from living organisms two categories: fat soluble and water soluble 1 . Helps bones and teeth develop 2. salts regulating body fluids Living things need meat, dairy products, and vegetables

12. Minerals (Calcium) most common mineral in the human body 99% in the body is found in bones and teeth age 30 the body gradually loses calcium critical of maintaining a healthy skeleton Adults-1000 milligrams per day (ages 19-50 years). Sources -kale, broccoli, bokchoy, cabbage, mustard, and turnip greens

13. Minerals (Potassium) -also known as an electrolyte -capable of conducting electricity -adults-4.7 grams every day -richest sources-fruits and vegetables -tight control of cell membrane is critical for nerve impulse transmission, -muscle contraction, and heart function

14. Vitamins Vitamin D-milk helps bones Vitamin A-carrots helps you see Vitamin C-oranges helps body heal Vitamin B-leafy vegetables helps make protein and energy Two types-fat soluble and water soluble Vitamin A ,Vitamin B1 ,Vitamin B2 ,Vitamin B3 ,Vitamin B5 ,Vitamin B6 ,Vitamin B9 ,Vitamin B12 ,Vitamin C ,Vitamin D ,Vitamin E ,Vitamin K,Vitamin H

15. Vitamin A occurs in two forms in nature found in foods such as fish oils and liver beta-carotene (provitamin A) is found in plants liver regulates the blood level of vitamin A protein and fat intake is required for a good absorption Function: -Vitamin A is needed for new cell growth, healthy skin, hair, and tissues, and vision in dim light

16. Vitamin B also known as thiamin helps your body convert blood sugar into energy keeps mucus membranes healthy essential for nervous system Women-1.1 milligrams per day Men-1.5 milligrams per day

17. Water scientific word-H20 an odourless, tasteless, transparent liquid covers 70% of the earth's surface only 3% is fresh water a compound of hydrogen and oxygen necessary for life

18. Water(sources) -beverages -vegetables -cooked rice -fruit -cooked pasta -soup -milk -desserts
