ALL ABOUT NUTRITION!Definitions Nutrition: Its the study of how your body uses the nutrients in the foods you eat.

NUTRIENTS
3Research has shown over the test of time just how important the foods you eat are for your health and well-being.
In Spring 2011, research revealed that the foods a child eats the first 5 years of life sets the stage for the types of illnesses he/she will develop as an adult.
In Fall 2011, research also found a link between certain health ailments of children based upon the foods the mother ate while pregnant.The saying, You are what you eat is true in many ways.

5Our bodies building materialsEnergy to do thingsHealth protection
The foods we eat give:
Helps build & repair body tissue. When in excess supply, protein can be used for energy (or when we dont eat enough carbs or fat). Protein is found in EVERY cell of your body from hair to finger nails andmuscles.
PROTEIN7Protein Food Sources meat, poultry, milk products, eggs, dried beans, peas, lentils, peanuts, peanut butter and other nuts, tofu
CarbohydratesMajor source of energy for body activitiesGive us heat energy for maintenance of body temperatureIf we dont eat enough carbohydrates, our body will burn protein instead.Simple Carbohydrates: (produce instant, but short term energy) sugar, honey, molasses, syrups, jams, jellies, and candy
Complex Carbohydrates: (produce longer term energy for endurance) from the starch in cereals, pasta, rice, grains and vegetables, such as potatoes & corn.
Food Sources of Carbohydrates
Provide us with that satisfied feeling after eating. Fats have 9 calories per gram, which take longer to burn than proteins and carbohydratesSource of stored energy and the carrier of essential fatty acids and vitaminsProvide protection for internal organsExcess fat intake is stored as body fat, which forms a cushion around the body for padding, as well as insulation from hot and cold temperatures.FATSButter, margarine, vegetable oils, salad dressings, mayonnaise, meat and dairy products.
We need just 1 Tablespoon of fat each day in order to digest and absorb certain nutrients.
Sources of FatType of FatsSaturated Fats: come from animals (the bad kind of fat with cholesterol) Animal fat is solid at room temperature. Think about what happens to bacon fat when it cools? Unsaturated Fats: come from vegetables (the healthy fat).Healthy vegetable fats are liquid at room temperature
MINERALSFurnish building materials and help regulate body functions. Its similar to needing oil in a carit makes the parts move smoothly and freely.
**Minerals= Calcium, Phosphorus, Iron, Iodine**
Remember MIPIC (my/me pic)
CALCIUM Necessary for strong bones and teethAlso needed for blood clot formation to form a scab to heal woundsImportant for maintaining normal muscle and nerve functionsMilk and dairy products, broccoli, dark green leafy vegetables (especially spinach), salmon, sardines and enriched breads, cereals, and grains.
Sources of Calcium
Food Sources: liver, meat, fish, poultry, eggs, milk, cheese, whole grain bread and cereals, nuts.Phosphorus Works along with calcium Important for development of nerve tissue
Necessary for the formation of hemoglobin (protein in red blood cells that carries oxygen) in the blood
You will become anemic if you dont have enough iron, causing you to feel very weak and tired, and possibly cause the whites of your eyes to turn yellow.IRONFood Sources of Iron red meats, liver, kidneys, egg yolks, oysters, dried beans, whole grains and enriched breads and cereals, dark green leafy vegetables, raisins, dried apricots, and other dried fruit
Helps thyroid gland to function properlyDeficiency causes goiterthe thyroid gland tries so hard to absorb iodine in the foods you eat, it enlarges and creates a tumor that has to be removed.
Food Sources: Iodized salt and SeafoodIODINE
*VITAMINS*Help regulate the chemical processes in your body
Help your body store and use energy for growth and development
Needed for general health maintenanceA, B, C, D, E, K
Fat Soluble Vitamins: A, D, E, KThese vitamins will only dissolve in fat in order for our body to absorb them.
Water Soluble Vitamins: B & CThese vitamins will only dissolve in water in order for our body to absorb them.Classifications of Vitamins

How Vitamins are AbsorbedFat soluble vitaminImportant for proper vision, especially in dim light. (helps your eyes adjust to darkness when you turn out the lights)Prevents night blindnessHelps maintain smooth, healthy skinNecessary for growth and reproduction and normal bone developmentVitamin A
Food Sources for Vitamin AAll foods that are yellow or orange, or were yellow or orange before ripeningLiver, egg yolks, dark green and yellow vegetables, sweet potatoes, carrots, milk, butter, margarine, apricots, yellow-orange fruits
Water soluble vitamin
The 3 most important types of Vitamin B to prevent an assortment of types of malnutrition are:Thiamin (B1)Riboflavin (B2)Niacin (B3)
Vitamin BPromotes the normal working of the central nervous systemAids in digestion and promotes healthy appetiteKeep the eyes, skin and mouth healthyFunctions of Vitamin BMeat, pork, fish, liver, dried beans, peas, whole grain and enriched breads and grains, & cereals, eggs, dark leafy veggies, peanuts
Food Sources for Vitamin BWater soluble vitaminNecessary for strong body cell and blood vessel development and maintenanceImportant in healing woundsOffers protection and resistance to stress and illnessVitamin C
Citrus fruits, strawberries, blueberries, cantaloupe, broccoli, cabbage, tomatoes,kiwi, green peppers, potatoes, & dark leafy vegetables Sources for Vitamin CFat soluble vitamin
Enables the body to use the minerals, calcium and phosphorus in a normal way in building sound bones and teeth.
This is the only Vitamin our body can make. The body can convert the rays from the sun on your skin into Vitamin D. Vitamin D
Sunshine on our skin, eggs, cheese, milk that has been fortified with Vitamin D, fish (tuna, mackerel, sardines), fish liver oils, boxed ready to eat cereals Sources for Vitamin DFat Soluble VitaminServes as an antioxidant- protects cells from damageVitamin E is put in many skin care products for healthier and more youthful looking skin by slowing down oxidation of the skin cells, so the face looks smoother and younger longer.
Vitamin EEgg yolks, vegetable oil, whole grain bread and cereals, liver, leafy green vegetables
Sources of Vitamin EFat soluble vitamin needed for normal blood clotting. (Do you remember which other nutrient helps clot blood? Hint: C _ _ _ _ _ _ ).Food Sources: pork, liver, spinach, broccoli & other dark leafy veggies, egg yolks, cauliflower, brussel sprouts
Vitamin K
Aids in regulating body temperatureCarries nutrients to body cells and waste products awayWe need to drink 6 to 8 glasses of water a day. More than 80% of our body is made up of waterAids in digestion92% of our blood is made up of water
WATERCelluloseNeeded in our digestive track for roughage
Food Sources: the little fibers in celery or leafy vegetables (When you break apart celery and other leafy vegetables, you can see the little strands of cellulose)
Needed for roughage in colon and intestinesPrevents colon cancerFood Sources: whole grains and brans, flax seedFiberA measure of energy value in food (it tells you how much energy that can be generated from eating food items)Growth, breathing, and physical activity involve some sort of expenditure of energy.Weight is maintained by burning off the exact number of calories that you take in each day.
