This video explains the 6 basic nutrients - carbohydrates, fats, proteins, vitamins, minerals, and water - and how they affect the body's health. It discusses the role of nutrients in providing energy, building and maintaining body tissues, preventing chronic diseases, and the difference between physical need and psychological desire for food.

Vocab • Minerals- Inorganic substances that the body cannot manufacture, but that act as catalyst, regulating many vital body processes. • Nutrients- provide you with substances you need to grow & develop • Vitamins- compounds that help regulate many vital body processes • Carbohydrates- the starches & sugars found in food • Proteins- nutrient that helps build and maintain body tissues • Fats- a natural oily or greasy substance occurring in animal bodies
OBJECTIVES • Students will know the 6 basic nutrients. • Students will understand how proper nutrition affects the health triangle. • Students will be able to explain and describe what each basic nutrient does for the body.
Why do You Eat?The body has a physical need for food. Many peoples eating habits are ruled by their appetite. Your eating habits stem from both a physical need for food and a psychological desire. Learning to recognize the difference helps you make more healthy food choices. • Physical Need • Hunger- natural drive which protects you from starvation • When your stomach is empty, its walls contract stimulating nerve ending…THIS IS WHY YOUR STOMACH GROWLS.
DESIRE FOR FOOD • Desirefor food is called appetite • Appetite is desired– rather than a need. - Appetite is learned-shaped by emotions & environment. -Most people eat past the point of feeling full because their appetite continues to be stimulated after their hunger has been satisfied
NUTRITION THROUGHOUT LIFE 1. Nutrition-process by which the body takes in & uses food. a. nutrients in food provide you with substances you need to grow & develop. 1.enables you to have energy, feel & look your best, and stay mentally alert. 2.Prevents chronic diseases-heart disease, stroke, cancers, and diabetes. b. Calories- A unit of energy.
BMR- Basal Metabolic Rate • The number of calories you'd burn if you stayed in bed all day or did not move. • The rate at which the body uses energy while at rest to keep vital functions going, such as breathing and keeping warm. • a regular routine of cardiovascular exercise can increase your BMR, improving your health and fitness when your body's ability to burn energy gradually slows down (when you get old).
6 Basic Nutrients • Carbohydrates • Fats • Protein • Vitamins • Minerals • Water
Carbohydrates- the starches and sugars found in food. • Body’s preferred source of energy • 4 calories per gram of carb. • 2TYPES OF CARBS: • Simple- Present in fruits, some veggies and milk. • fructose (fruit) • Sucrose (table sugar) • lactose (dairy products) • Candy, soda, cookies, jelly • Complex- Starches-made from sugars linked together. • Rice, pasta, grain, seeds • Potatoes and yams • During digestion starches break down into sugars
Fiber- special form of complex carb that aids in digestion. • Helps waste move through the body • Prevents constipation & appendicitis • Cannot be digested • Whole grain breads, vegetables, fruits and seeds
Protein- nutrient that helps build and maintain body tissues • Builds the framework of your body, including muscles, organs, bones, and connective tissues. • In the form of enzymes, it helps your body digest food. • As a hormone, it tells your body when to use food as energy and when to store it as fat. • It transports oxygen through your blood to your muscles and organs. • As an antibody, it protects you from illness when viruses and bacteria attack.
3. • FATS ARE THE MOST CONCENTRATED ENERGY FORM AVAILABLE. IT DELIVERS 2 TIMES THE ENERGY OF CARBS OR PROTEIN (9 CALORIES FOR EVERY GRAM OF FAT) • Lipids- fatty substance that does not break down in water FAT
2 Types of Fat 1. Saturated Fat- BAD FAT 2. Unsaturated Fat- GOOD FAT
Saturated Fat: BAD!!! • Solid at room temp. • Animal Fat (beef, pork, egg yolks, dairy foods) • Solid at room temp. (ex. animal fat, butter) • Tropical oils- (ex. Palm or Coconut) • Butter and shortening • High intake increases your chance of heart attack/ disease • Tend to be stored rather than burned
GOOD FAT- Unsaturated Fat • Liquid at room temp. • Vegetable • olive oils • margarine
CHOLESTROL • Cholesterol- fatlike substance produced in liver of all animals- found only in foods of animal origins. • Causes heart and other circulatory diseases.
Vitamins • Compounds that help regulate many vital body processes, including digestion, absorption, and metabolism • 2 TYPES OF VITAMINS • Water soluble- can’t be stored (ex. C and B) • Fat soluble- stored in fat (ex. A,D,E, & K)
Water Soluble Vitamins • Dissolve in water and pass easily through the bloodstream • Vitamin C and all B vitamins • Cannot be stored, but taken in daily. Excess are secreted in urine.
FAT SOLUABLE VITAMINS • Dissolve in fatty materials • Vitamins A, D, E, and K • Stored in the body’s fat tissue • Occurs naturally in foods. • Vegetable oil • Liver • Eggs
Minerals • Inorganic substances that the body can’t manufacture, but act as a catalyst, regulating many vital body functions • Body requires some in large amounts and others as trace minerals (tiny amounts) • Important when growth is rapid as teens • Essential for hemoglobin • Iron • Iodine • copper
Most important mineral=Calcium • Develops and maintains bone strength • Found in dairy products and green leafy vegetables • Aids in muscle contraction, blood clotting, functions of nervous system • Comes from: milk and most dairy products, leafy green vegetables • Helps weight loss • Harvard research showed that those that got daily recommendation of calcium were 60% less likely to be overweight • Calcium seems to limit the amount of new fat that your body can produce • Lack of calcium leads to osteoporosis- bones become brittle and weak
6. Water- A regulator and vital to everybody’s function. • Regulator and vital to everybody’s function • Carries nutrients and transports waste from cells • Lubricates joints • Enables you to digest food • Your body uses up to 10 cups of water daily • Water is the nutrient that makes up the greatest percentage of the body • Should drink 6-8 cups daily
