Giving Your Body What it Needs
Everything we eat contains nutrients.The body uses nutrients in many ways:
As an energy sourceTo heal, build, and repair tissueTo sustain growthTo help transport oxygen to cellsTo regulate body functions
There are 6 different types of nutrients.
1. Carbohydrates
Starches & sugars found in foods, which provide your body’s main source of energy.
45-65% daily calories should come from carbohydrates
1g = 4 calories
Role of Carbohydrates:Body breaks them
down to simplest form, glucose. Glucose is the main fuel for the body’s tissues
Glucose can be stored in the body’s tissue & used later.
Simple Carbohydrates
Sugars that provide quick energyFructose (found in
fruits)Lactose (found in milk)Naturally occur in
honey & maple syrupAdded to cold cereals,
bread, bakery products
Complex Carbohydrates
Long chains of sugars linked togetherTake longer to break
down = longer source of energy
Found in breads, pastas, beans, & root vegetables (potatoes)
Fiber
Tough, complex carbohydrate that the body cannot digest
Moves waste through the digestive system
Helps you to feel fullReduce risk of cancer,
heart disease & Type 2 Diabetes
Need 20-35 grams/day
2. Protein
Nutrients the body uses to build & maintain its cells & tissues
10-15% daily calories should come from protein
1g = 4 calories
Amino Acids
Amino acids are the building blocks that make up proteins 9 are considered essential
—your body cannot produce them & must get them from food
11 are considered nonessential because the body can produce them
Complete Proteins contain all of the 9 essential amino acids Found in animal sources
(meat, eggs, dairy) and from soy
Incomplete Proteins are missing 1 or more essential amino acids Plant sources (grains,
nuts, seeds, legumes) are usually missing 1 amino acid
Role of Proteins
Basic building materials of all body cellsProtein helps body growMaintains muscles, ligaments, tendonsCarries oxygen (Hemoglobin in red blood
cells)Can be used as an energy source, but
doesn’t provide it quickly or easilyAct as hormones to regulate body systems
