  1. Basic Nutrition Understand the fuel your body needs and how it is used.

  2. Topics of Discussion • Why is proper nutrition important? • What nutrients does your body need to run efficiently? • What are some key concepts to an effective nutritional program? • What are the results of poor nutrition?

  3. Why is proper nutrition important? • All living things need food and water to live. • All human beings need “good food” to live well. • Food = energy (measured in calories) • Carbohydrates - 1 gram = 4 calories • Protein - 1 gram = 4 calories • Fats - 1 gram = 9 calories • Proper nutrition provides the body with the nutrients necessary to build, maintain, and repair tissues.

  4. Types of Nutrients • Macro-Nutrients – essential for human survival and growth • Carbohydrates • Proteins • Fats • Water • Micro-Nutrients – essential for growth and enhance the function and usability of macro-nutrients • Vitamins • Minerals The difference between macro and micro nutrients is the amount your need each day. Macro-nutrients must exceed one gram per day.

  5. Carbohydrates • Provide energy for your body by converting to glucose. • Three types of carbohydrates: • Simple – one or two units of sugar • Complex – more than two units of sugar • Dietary fiber – complex carbohydrates that are not a source of energy and add no calories to your diet. • Protect your muscles. • Regulate the amount of sugar circulating in your body. • Assist in the body’s absorption of calcium. • May help lower cholesterol levels and regulate blood pressure.

  6. Proteins • Used for tissue growth and repair. • Two types of Proteins: • Complete Proteins – contain sufficient amounts of all essential amino acids. • Incomplete Proteins – missing or do not have enough essential amino acids. • Amino Acids are the building blocks for protein (20 different types). • Within six months, every protein molecule in your body is broken down and replaced. • The more intensely you train, the more protein is required for repair and growth. • Consuming more protein than the body needs can result in an increase in fat storage.

  7. Fats • A healthy body needs fat. Major uses for FAT • Provides a source of stored fat. • Gives shape to your body. • Cushions your skin. • Acts as an insulator in order to reduce heat loss. • Protects your organs if you fall or are injured.

  8. Vitamins and Minerals • Vitamins and minerals act as regulators and catalysts for a variety of bodily functions. • Vitamins are essential for: • Building body tissues such as bones, skin, glands, nerves, and blood. • Assisting in the metabolizing of proteins, fats, and carbohydrates so you receive energy from food. • Promoting healing • Preventing nutritional deficiency diseases. • Minerals are essential for: • The formation of strong bones and teeth • Helping to control the nervous system • Fluid balance in tissues • Muscle contractions • Minerals and most vitamins must be supplied through diet since they are not made in the body.

  9. Water • Your overall body is between 70 - 80% water. • Your muscles are about 75% water • Your body needs water to: • Digest food • Carry waste products out of your body • Regulate body temperature • Lubricate moving parts • Your body does not store water so you must take in a new supply every day. • The National Research Council’s Food and Nutrition Board recommends one milliliter (ml) of water for each calories of food we consume.

  10. Key Concepts to an Effective Nutritional Plan • Breakfast is the most important meal of the day. • Attempt to eat 4-6 meals per day. • Minimum of 8 glasses of water per day. • Attempt to consume carbohydrates, proteins, and fats in every meal. • Vegetables are the best source of vitamins and minerals. • Read labels and understand serving sizes. • Supplements should be used as supplements. • Make a lifestyle change – diets often fail.

  11. Examples of Highly Nutritious Snacks • Peanut butter and jelly on wheat bread • Apples and peanut butter • Low fat yogurt • Cheese sticks • Granola / trail mixes • Turkey Roll-ups

  12. Results of Poor Nutrition • Obesity • Heart Disease • Hypertension • Diabetes • Osteoporosis • Bones may break due to a lack of calcium • Gums may bleed due to low Vitamin C • Low Iron count
