Nutrition
The science of food and the ways in which a body uses food.
Nutrients
Substances in food that provide energy or help form body tissues. They are necessary for life and growth.
What is a calorie and how many does each of the nutrients with calories have
A unit of measurement for energy
Carbs – 4 cal/gram
Protein – 4 cal/gram
FATS - 9 cal/gram
Simple carbohydrates
Simple sugars do not need to be broken down in the metabolic process
Complex carbohydrates
3 or more sugars attached to form long chain molecules. They need to be broken down and take time to digest and be used as energy.
What type of carbs are we able to use faster and easier after eating them
Simple
What percent should carbohydrates take up of daily calories and why
50% or more
They are a major source of energy and also help repair tissues.
What is dietary fiber
It is a complex carbohydrate but it is not digested. It is made up of the parts of plants we cannot digest.
Why does fiber do
Helps speed up food moving through the digestive tract. It prevents constipation and makes a person feel full
What do high fiber diets help prevent
Colon cancer
What kinds of foods is fiber found in
Fruits, vegetables, grains and beans
Why do we need fat
Stores energy Pad and protect organs Insulate body from cold Important ingredient in several hormones Necessary for storage and transport of certain vitamins throughout the body
What fat do we want to avoid
Saturated fat
Saturated fat
-Solid fat
Is solid at room temperature except for coconut oil and palm oil. It clogs arteries with plaque formation and contributes to heart disease. It is animal fat, milk fat and some oil fats
Unsaturated fat
-Liquid fat
Is liquid at room temperature and is from plant sources like veg. oil, corn oil, peanut oil. It is cholesterol free.
Trans fats
Hydrogenated oils (trans fats) are vegetable oils that have been altered to make them more useful in commercial food processing – they are solid oils
Where is trans fat
Found in margarine, chips, cookies, and other snack foods.
What can hydrogenated oils do
Raise blood cholesterol levels as much as saturated fats
What is Cholesterol
A fat-like substance in some foods of animal origin. It is produced by the liver and other organs. Our bodies make all the cholesterol we need.
What is HDL
High-density lipoprotein (HDL)
Good cholesterol, carries cholesterol from blood stream to the liver, where it is broken down to be used or removed from the body.
What is LDL
Low-density lipoprotein (LDL)
Bad-cholesterol – carries chol. And other fats from the digestive system through blood to the body’s cells. Excess cholesterol builds up on the walls of blood vessels – clogged arteries result.
Proteins
Made of carbon, hydrogen and oxygen, but also contain nitrogen. Necessary for growth and repair of body tissues. Made of amino acids. There are 20 total amino acids, 11 can be made in the body, 9 others must be supplied by food: called essential amino acids
Complete proteins
what is is it and where is it found
Contain all 9 essential amino acids
Meat, poultry, fish and milk products – complete proteins
Incomplete proteins
Contain only some of the 9 essential amino acids
Vitamins
Compounds that help regulate certain chemical reactions in the body. Only vitamins the body makes are D and K.
