A substance in foods that helps with body processes

NUTRIENTS

What are the 6 essential nutrients?

A unit of ENERGY is called a calorie3500 calories equal 1 pound of fat.

1 gram of protein yields 4 calories1 gram of carbohydrates yields 4 calories1 gram of fat yields 9 calories

CALORIC INTAKE: the number of calories a person takes in from food and beverages

LUCKY CHARMS

PROTEIN

Nutrient that is needed for GROWTH and to BUILD and REPAIR body tissue.

COMPLETE PROTEIN: contains all the essential amino acids.

MeatFish

PoultryEggs

PROTEIN

INCOMPLETE PROTEIN: from plant sources that does not contain all the essential amino acids.

GrainsNuts

BeansSeeds

PROTEIN

Amino Acids: the BUILDING BLOCKS that make up a proteinYour body needs 20 amino acids to function properly

11 out of 20 amino acids are produced by your body

9 out of 20 amino acids must come from food sources.

PROTEIN

For teens 14-18 who get less than 30 minutes per day of exercise:Girls need 5 ounces per day.Boys need 6 ½ ounces per day.Examples are 1 oz.. of meal, fish or poultry; 1 egg; ¼ cup of beans; 1 tbsp.. Of peanut butter; ½ oz.. of nuts or seeds equal 1 oz. of protein.

RECOMMENDATION

CARBOHYDRATES

Nutrient that is the main source of ENERGY

Includes sugars, starches, and fiber

Excess carbs are stored as fat.

SIMPLE CARBOHYDRATES: Sugars that enter the bloodstream rapidly and provide quick energy.

Digested/enters bloodstream rapidly

Provides calories, but very few vitamins and minerals

“Empty calories”

CARBOHYDRATES

EXAMPLES?

COMPLEX CARBOHYDRATES: provide long-lasting energy. Ex: starches and fiber

More than two sugars linked together

Should be the body’s main source of caloric intake

CARBOHYDRATES

EXAMPLES?

A starch is a food substance that is made and stored in most plants. provides long-lasting energy

STARCH

When broken down in the mouth by saliva and digestive juices, these complex carbs are converted into GLUCOSEGlucose is used by cells to provide ENERGY and HEAT to the body

Remaining glucose is converted into GLYCOGEN to be stored in muscle tissue in order to be utilized later on for energy

GLUCOSE

FIBERCannot be DIGESTEDHelps move food through the digestive system

2 Types:SolubleInsoluble

Soluble:Reduces levels of CHOLESTEROLOatmeal, beans, and barley

FIBER

Insoluble:Binds with WATER to help produce bowel movements

Reduces risk of colon cancerWheat products, leafy vegetables, fruits

FIBER

Orange Soda - 12 oz. Welch’s Grape Juice - 11.5 oz.

Gatorade - 20 oz. Froot Loops Cereal

Starbucks Grande Mocha Frappacino 16 oz.

Yoplait Yogurt – 6 oz. (flavored 99% fat free)

ANSWERS

A nutrient that provides ENERGY and helps the body store and use VITAMINS

FATS

The Dietary Guidelines for Americans 2010 recommend that Americans:Consume less than 10% of calories from saturated

fats.Replace solid fats with oils when possible.Limit foods that contain synthetic sources of trans

fatty acids (such as hydrogenated oils), and keep total trans fatty acid consumption as low as possible.

Eat fewer than 300 mg of dietary cholesterol per day.

Fat intake should not EXCEED 20% of daily caloric intake.

HOW MUCH TOTAL DIETARY FAT DO I NEED?

SATURATED FAT: type of fat found in dairy products, solid vegetable fat, meat, and poultryUsually solid form at room temperature

FATS

CHOLESTEROLCholesterol is found in every cell of the body and has important natural functions. It is manufactured by the liver but can also be taken in from food. It is waxy and fat-like in appearance.The parcels of cholesterol are carried by two types of lipoprotein:2 • Low-density lipoprotein (LDL - cholesterol

carried by this type is known as 'bad' cholesterol)

• High-density lipoprotein (HDL - cholesterol carried by this type is known as 'good' cholesterol).

UNSATURATED FAT: type of fat found in plant products and fish

Usually liquid form at room temperature

Two kinds:Monounsaturated- sunflower, corn, and soybean oils.

Polyunsaturated- olive and canola oils.

TYPES OF FATS

TRANS-FATTY ACIDS: fatty acids that are formed when vegetable oils are processed into solid fats such as margarine or shortening.HYDROGENATION : process of converting vegetable oils into solid fats

FATS

RESULTS

Helps the body use its sources of ENERGY but does not directly provide ENERGY.

Two Types:Fat-solubleWater-soluble

VITAMINS

Dissolves in FAT and can be stored in the body:

Vitamin AVitamin DVitamin EVitamin K

FAT-SOLUBLE VITAMINS

Vitamin A: keeps eyes, hair, and skin healthy: Found in dairy products and fruits

Vitamin D: aids in formation of bones and teeth: Found in meat and dairy products

FAT-SOLUBLE VITAMINS

Vitamin E: helps maintain and form cells: Found in green vegetables and whole-grains

Vitamin K: necessary for normal blood clotting: found in cheese and leafy green vegetables

FAT-SOLUBLE VITAMINS

Dissolves in WATER and cannot be stored in the body in significant

amountsVitamin CVitamin B Complex

WATER-SOLUBLE VITAMINS

Vitamin C: helps strengthen blood vessel walls, strengthens your immune system, and aids in iron absorption.

WATER-SOLUBLE VITAMINS

Vitamin B1: thiamin: responsible for nerve function and is found in whole grains, eggs, and poultry

Vitamin B2: riboflavin: helps body use energy and is found in yeast, fish, and dairy products

Vitamin B3: niacin: helps body use energy and can be found in yeast, fish, and dairy products

WATER-SOLUBLE VITAMINS

Vitamin B6: helps body use fat/take in protein and can be found in whole grains and leafy vegetables

Vitamin B9: aids in the formation of hemoglobin and can be found in liver, green vegetables, and whole grains.

Vitamin B12: necessary for the formation of red blood cells and can be found in meat and dairy products

WATER-SOLUBLE VITAMINS

A chemical that REGULATES chemical reactions in the body

Essential in METABOLISM and NUTRITION

MINERALS

Macro Minerals:Minerals needed in amounts greater than 100 mg

The major minerals are sodium, potassium, calcium, phosphorus, magnesium, manganese, sulphur, cobolt and chlorine.

Micro-Minerals:Also known as TRACE MINERALSNeeded in small amounts
