Chapter 8 – Food and Nutrition
FOOD SUPPLY Food provides your body with nutrients. These substances your body needs to regulate body functions, promote growth, repair body tissues, and obtain energy. Your body requires 40 different nutrients to accomplish these tasks. The process by which the body takes in and uses these nutrients is called metabolism.

FOOD SUPPLY ENERGY When your body uses the nutrients in foods, a series of chemical reactions occur inside your cells as a result energy is released. Metabolism is a chemical process by which your body breaks down food to release energy. The amount of energy released when nutrients are broken down is measured by calories.

vitamins, minerals, and water
The 6 Basic Nutrients nutrients % of daily food intake carbohydrates 40 % proteins 35 % vitamins, minerals, and water 15 % fats 10 %

CARBOHYDRATES: supply energy for your body
SIMPLE ALSO KNOWN AS Sugar Found in fruits, vegetables and milk . It provides energy for your body cells. COMPLEX STARCHES Found in potatoes, rice and grains. Your body breaks these down to simple sugar. FIBER Found in cereals, whole grain, veggies, nuts and beans. Prevents constipations, colon cancer, and heart disease.

YOUR BODY’S ENERGY RESERVE
Extra carbohydrates that your body does not use create extra glucose. If you eat too many CARBOHYDRATES, and the GLYCOGEN stores are full the excess carbohydrates are stored as FAT.

Fats supply your body with energy, form your cells, maintain body temperature and protect your nerves. FATS

Function of Protein: GROW AND REPAIR BODY TISSUE

vitamins and minerals Vitamins: Nutrients made by living things and assist in chemical reactions. Minerals: Nutrients that occur naturally in the rocks and soil – the body only needs small amounts of these.

Minerals deficiency Osteoporosis – lack of calcium resulting in weak and brittle bones Anemia – lack of iron resulting in the person becoming tired and weak easily

All of your body’s processes require water!
You can lose 6-8 cups of water during every hour of exercise! Dehydration is serious reduction in the body’s water content Symptoms include weakness, rapid breathing and weak heart beat Now... Figure out how many ounces of water you should drink every day! YOUR BODY WEIGHT = __________ / 2 = __________ OUNCES OF WATER YOU SHOULD DRINK EXAMPLE YOUR BODY WEIGHT = 140 / 2 = 70 OUNCES OF WATER YOU SHOULD DRINK

POP vs. WATER What do you drink???
Do you know how it can help or hinder your daily activities? Lets find out

Water 75% of Americans are chronically dehydrated.
In 37% of Americans, the thirst mechanism is so weak that it is mistaken for hunger. One glass of water will shut down midnight hunger pains for almost 100% of the dieters studied in a University of Washington study. Lack of water, the #1 trigger of daytime fatigue A mere 2% drop in body water can trigger fuzzy short-term memory, trouble with basic math, and difficulty focusing on the computer screen or on a printed page. Drinking 5 glasses of water daily decreases the risk of colon cancer by 45%, plus it can slash the risk of breast cancer by 79%., and one is 50% less likely to develop bladder cancer.

Coke In many states the highway patrol carries two gallons of Coke in the trunk to remove blood from the highway after a car accident. To clean a toilet: Pour a can of Coca-Cola into the toilet bowl and let the 'real thing' sit for one hour, then flush clean. The citric acid in Coke removes stains from china. To remove rust spots from chrome car bumpers: Rub the bumper with a rumpled-up piece of Reynolds Wrap aluminum foil dipped in Coca-Cola. To clean corrosion from car battery terminals: Pour a can of Coca-Cola over the terminals to bubble away the corrosion. To loosen a rusted bolt: Apply a cloth soaked in Coca-Cola to the rusted bolt for several minutes.

WHAT DO YOU PUT IN YOUR BODY?
Coke #1 the active ingredient in Coke is phosphoric acid. It will dissolve a nail in about four days. Phosphoric acid also leaches calcium from bones and is a major contributor to the rising increase of osteoporosis. #2. To carry Coca-Cola syrup! (the concentrate) the commercial trucks must use a hazardous Material place cards reserved for highly corrosive materials. #3. The distributors of Coke have been using it to clean engines of the trucks for about 20 years! WHAT DO YOU PUT IN YOUR BODY?

High Blood Pressure/Cholesterol Diabetes
Weight and Management Overweight: BMI over 30 Health Risks High Blood Pressure/Cholesterol Diabetes Heart Disease, stroke, certain cancers More people are overweight because their calorie consumption has increased and their calorie usage has decreased. Underweight: BMI under 14 Anemia Heart irregularities Trouble regulating body temperature Think *pair*share

Healthy Weight Management
An average person needs 2500calories to have enough energy to perform daily tasks. Any additional calories taken beyond those required for their BMR can be stored as fat_. 1 pound = 3500 calories If a person wants to lose 1 pound, they must BURN or use 3500 calories. If a person wants to gain 1 pound, they must CONSUME 3500 extra calories above their BMR. The healthiest way to lose weight is to lose 1 to 2 pounds a week. In order to lose 1 pound a week you must reduce your calorie intake by 500 calories a day. Complete the word problems at bottom of page in the packet.

Food Label on page 6 of packet
Use the % Daily Value (% DV) column: 5% DV or less is low, and 20% DV or more is high. Keep these low: saturated and trans fats, cholesterol, and sodium. Get enough of these: potassium and fiber, vitamins A, C, and D, calcium, and iron. Check the calories: 400 or more calories per serving of a single food item is high. Food Label on page 6 of packet
