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

Carbohydrates • Complex • helps you feel full• carbohydrate foods are better

choices than others• Simple• contain vitamins• found in refined sugars

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

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

Protein• builds up the tissues in your body• make hemoglobin that carries

oxygen to every part of body• beef, poultry, fish, eggs, dairy

multiply your weight in pounds times 0.5 or you can just take your weight and divide by 2

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

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

• 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

Minerals

• 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, bok choy, cabbage, mustard, and turnip greens

Minerals (Calcium)

• -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

Minerals (Potassium)

• 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 solubleVitamin 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

Vitamins

• 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

Vitamin A

• 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

Vitamin B

• 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•

Water

-beverages-vegetables-cooked rice-fruit-cooked pasta-soup -milk-desserts
