Why should you eat a well balanced diet every day? To replace nutrients used daily by the body.

Fundamentals of Nutrition Nutrition= digestion, metabolism, circulation, and elimination Nutritional status refers to the state of ones nutrition. Wellness= State of good health with optimal body function (requires good nutrition)

Nutrition pleats a large role in determining: Height Weight Strength Skeletal & Muscle Development Physical Ability Resistance to Disease

Nutrition plays a large role in determining: Appetite Posture Complexion Mental Ability Emotional and Psychological Health

Immediate effects of good nutrition Include: Healthy Appearance Good Attitude Proper sleep and bowel habits High energy level Enthusiasm Freedom from anxiety

Good Nutrition may delay or prevent the following: Hypertension Atherosclerosis Osteoporosis Malnutrition Obesity

Essential Nutrients Composed of chemical elements found in food. Used by the body to perform body functions. Nutrients in foods replace those used by the body.

6 Groups of Essential Nutrients Carbohydrates Fats Proteins Vitamins Minerals Water

Carbohydrates Major source of human energy Starches or sugars Easily digested, grow well in most climates, keep well without refrigeration.

Carbohydrates Main sources: bread, cereals, pasta, crackers, potatoes, corn, peas, fruits, sugars and syrups Cellulose: It provides bulk in the digestive tract and causes regular bowel indigestible carbs, provides bulk (bran, whole-grain cereal, fibrous fruits & veggies)

Fats Lipids Concentrated form of energy Help maintain body temperature by providing insulation Help cushion organs and bones

Fats Aid in the absorption of fat-soluble vitamins Provide flavor to meals Main Sources: butter, margarine, oils, creams, fatty meats, cheeses, and egg yolks Classified as saturated or polyunsaturated.

Fats Cholesterol- Fatty substance found in body cells and animal fats- found in egg yolk, fatty meats, shellfish, butter, cream, cheese, whole milk, & organ meats. *Excess cholesterol is believed to contribute to atherosclerosis.

Proteins Build and repair body tissue Provide heat and energy Help produce antibodies Made up of 22 amino acids (9 essentials) Main sources/complete proteins: meat, fish milk, cheese, eggs/ Incomplete proteins: Cereal, soybeans. Dry beans, peas, and peanuts

Vitamins Organic compounds that are essential in life. Regulate body functions. Repair body tissues. Only a small amount required-well balanced diet provides required vitamins. Excess or deficiency can cause poor health. Water soluble or fat soluble. Someone who eats a fat free diet could become deficient in : Fat-soluble vitamins.

Minerals Inorganic (nonliving) elements found in all body tissues. Regulate body functions. Build and repair body tissues. They include: calcium, phorphorus, Sodium, potassium, iron, Flourine and others.

Water Found in all body tissues Essential for digestion. Makes up most of blood plasma Helps body tissues absorb nutrients. Helps move waste material through body. Average person should drink 6-8 glasses of water a day. Nutrient that helps the body tissues absorb other nutrients.

Utilization of Nutrients                                See full-size image. scruss.com/.../wp-content/fast_food_kills.png 550 x 425 - 13k Image Utilization of Nutrients Digestion- breaks down the foods we eat Mechanical or Chemical Peristalis Absorption- process of taking in nutrients by the body. Most absorption occurs in the small intestine. Water, salts, and some vitamins in large intestine.

Utilization of Nutrients Metabolism- use of nutrients by the body. Basal metabolic rate (BMR) Measuring Food Energy 2. Calorie- the amount of heat produced during metabolism. Most people use an average of 3,500 calories per day. To lose weight, a person must take in fewer calories then are burned. To gain weight, a person must take in more calories than the body uses.
