1 Creative Cuisine Notes: Proteins, Water, Carbohydrates, Fats, Digestion, Absorption

2 A nutrient is a chemical substance in food that helps maintain the body. Nutrition is the study of how your body uses the nutrients. Malnutrition is a lack of the right proportions of nutrients over an extended period. A person who is malnourished may be underweight or overweight.

3 You can divide the nutrients into six groups: Carbohydrates – simple and compex Fats Proteins Vitamins – Water Soluble: C and Bs – Fat Soluble: A, D, E and K Minerals – Macro, need more than 100 mg daily – Micro, need less than 100 mg daily Water

4 Fortified foods are a food to which nutrients are added in amounts greater than what would naturally occur in the food.

5 Carbohydrates Body’s chief source of energy. – Three main types: sugar (glucose, fructose, gallactose, sucrose, lactose and maltose), starch and fiber Fiber is a form of complex carbohydrates from plants that humans can’t digest. Doesn’t provide the body w/energy but provides bulk and promotes normal bowel function.

6 Sources: Sugars: sweets (not too many), fruits Starch: bread, cereal, pasta, rice corn, potatoes, beans, peas Fiber: fresh fruits, vegetables, whole grain cereal products Deficiencies are rare. Too many = weight gain

7 Fats Important energy source. Belong to a group called lipids. Cholesterol is a fatlike substance found in every cell of the body.

8 Functions: provide energy, store energy, carry fat-soluble vitamins, carry flavor to make foods taste good, fat under skin provides insulation Deficiencies are rare in U.S. We need to limit excess fats

9 Proteins Made up of small units called amino acids. There are 20 amino acids: 9 of these are considered essential amino acids. The body cannot make some essential amino acids 11 of these are non-essential amino acids, body can make them fast to meet the needs

10 Complete proteins contain all 9 essential amino acids: animal foods and soybeans Complete proteins support growth and normal maintenance of body tissue. Incomplete proteins will NOT support growth and normal maintenance of body tissue.

11 Sources: lean meats, poultry, fish, milk, cheese, eggs, dried beans, peas and nuts Complete: Incomplete:

12 Water Function: 50 to 75% of body is water found both inside and outside of cells – Aids in proper digestion, cell growth and repair – Help regulate body temperature.

13 Sources:54% comes from liquids you drink 37% comes from foods Excretes through kidneys. Most people need about 8 glasses of water a day.

14 Digestion Digestion is the process of breaking down food into simple compounds the body can use. Digestion starts in the mouth and ends in the rectum. Peristalsis: waves of muscle contractions that push food through the digestive tract.

15 Absorption & Metabolism Absorption is the process of taking in nutrients and making them part of the body Metabolism: the chemical process that takes place in the cells after the body absorbs nutrients.
