  • Slide 1
  • Six Essential Nutrients
  • Slide 2
  • Food provides your body with NUTRIENTS. NUTRIENTS are substances that the body needs to 1.Regulate bodily functions 2.Promote growth 3.Repair the body tissues 4.Obtain energy. Your body requires many nutrients for these tasks but SIX ARE ESSENTIAL. An ESSENTIAL NUTRIENT is a nutrient that your body can not make so it must be consumed through a dietary source.
  • Slide 3
  • 6 ESSENTIAL NUTRIENTS: Fuel Nutrients Macro Regulatory Nutrients + Micro 1.Carbohydrates 2.Fats 3.Proteins 4.Water 5.Vitamins 6.Minerals Fuel Nutrients = Body uses to supply energy Regulatory Nutrients = Necessary in order for the body to function normally Macro-nutrients = Body needs them in LARGE amounts DAILY Micro-nutrients = Required in only small amounts (grams, mg and micrograms)
  • Slide 4
  • When your body uses the nutrients in foods, a series of chemical reactions occurs inside your cells. As a result, energy is released. Metabolism is the chemical process by which your body breaks down food to release this energy.
  • Slide 5
  • The amount of energy released when nutrients are broken down is measured in units called CALORIES.
  • Slide 6
  • 1. CARBOHYDRATES = SUGARS AND STARCHES FOUND IN PLANT AND DAIRY PRODUCTS THE FUNCTIONS AND BENEFITS OF CARBS : The bodys MAIN SOURCE OF ENERGY Fuel for the brain Fuel for muscles Low in calories (4 calories per gram) High in nutrients and fiber Contains no cholesterol 55-65% of total daily calories 4 calories per gram
  • Slide 7
  • TWO KINDS OF CARBS: 1.COMPLEX CARBS: - Starches and fiber (bread, pasta, potatoes, rice, etc. - Provide your body with the most energy - Refined (white bread, pasta) vs. Unrefined (whole wheat, grains) - Should try to eat unrefined carbs because fiber and nutrients have not been removed
  • Slide 8
  • 2. SIMPLE CARBS: - Natural Sugar provide energy but are usually high in calories - Fruit and veggies high in nutritional value - Candy and sugars- empty calories with no nutritional value
  • Slide 9
  • Fiber: Carbohydrates contain dietary fiber Fiber can not be digested but it assists digestion and strengthens intestines Fiber has many health benefits (helps with weight control, heart disease, diabetes, cancer and intestinal diseases) Best sources are from whole grain cereals and skins of fruit and vegetables
  • Slide 10
  • 2. FATS 30% of total daily calories 9 calories per gram Functions of Fat Source of energy but NOT the first source Provides essential fatty acids Support and cushion vital organs (protection) and insulates against heat and cold Cell membrane construction Oil in skin and hair Flavor and satiety (feeling of fullness, digested slowly) Transports fat soluble vitamins Regulates cholesterol usage
  • Slide 11
  • Most fats are a mixture of SATURATED AND UNSATURED FATS 1.Saturated Fats: The bad fat Solid at room temperature Causes build-up in arteries Comes mostly from animal products- lard, butter, milk and meat fats
  • Slide 12
  • 2. Unsaturated Fats: Liquid at room temperature Contain essential fatty acids- The good fats- Polyunsaturated (fish, sunflower, corn, whole grains) - Monounsaturated (nuts, olive, canola, peanut oils) ***SHOULD AVOID TRANS FATS (industrialized hydrogenated oil)
  • Slide 13
  • Cholesterol Fat related substance: Contained in saturated fat Is needed for cell and nerve make up, hormone and bile production Body produces adequate amounts already Body can handle an excess of 300 grams a day, then tends to build up Two Types of Cholesterol: 1.HDL- High Density Lipoprotein (Good cholesterol) {>35 is good} 2.LDL- Low Density Lipoprotein (Bad cholesterol) CLOGS ARTERIES {
