N UTRIENT A nutrient is a chemical that an organism needs to live and grow or a substance used in an organism's metabolism which must be taken in from its environment.

N UTRIENTS There are six classes of nutrients: Carbohydrates Fats Minerals Protein Vitamins Water

C ARBOHYDRATES Carbs are sugars and starches that the body uses for energy. Plants are the major source of carbs in our diets

S IMPLE C ARBOHYDRATES Sugars that are quickly digested and provide a boost of energy for the body.

S IMPLE C ARBOHYDRATES Foods with lots or sugar: oranges, milk, cookies, and candy

C OMPLEX C ARBOHYDRATES Starches that are composed of many sugars linked together. They provide the body with long term energy since they are digested more slowly

C OMPLEX C ARBOHYDRATES Complex Carbohydrate Foods: rice, beans, potatoes

P ROTEIN Provide the building materials to help the body grow and repair itself. Proteins are the basis of many animal body structures (e.g. muscles, skin, and hair) Proteins are made from many amino acids connected together in different arrangements.

C OMPLETE P ROTEINS Foods containing all 9 of essential amino acids Examples: fish, meat, eggs, milk, cheese

I NCOMPLETE P ROTEINS Foods that are missing some essential amino acids. For example: Legumes, nuts & whole grains

F AT ENERGY source for the body (more than carbs and proteins) Fats belong to a group of organic compounds called lipids which are substances that do not dissolve in water. Help protect and cushion vital organs as well as joints Insulate the body

U NSATURATED F ATS Foods with a lot of unsaturated fat: canola, safflower, and peanut oils, avocados

S ATURATED F ATS Contain fatty acids with the MAXIMUM amount of hydrogen atoms At room temperature, they are typically in solid form.
