  1. Picture This… • Think of your body as a coal furnace for a moment. At night, before bed, it’s as fired up as a bull rider on ephedrine (commonly used as a stimulant), right? Then, slowly but surely through the night, things cool way down. When you wake up, some red embers still flicker in the fireplace, but the house is as cold as the North Pole. So you go down, throw some more coal in the furnace, and fuel it. Gradually, you prod the fire back to life, and the house starts warming up again.

  2. Unit 1 - Nutrition

  3. Vocabulary Overview • Nutrition – The process by which the body takes in and uses food • Calories – Units of heat that measure the energy used by the body and the energy that foods supply to the body • Nutrients – Are substances in food that your body needs to grow, repair itself, and to supply you with energy • Antioxidant – A substance such as vitamin C or E that removes potentially damaging oxidizing agents in a living organism • Daily Value – The Daily Value serves as a basis for declaring on the label the percent of the DV for each nutrient that a serving of the food provides • Fad Diet - A reducing diet that enjoys temporary popularity

  4. New Food Pyramid

  7. What is a “Fad Diet?” • A reducing diet that enjoys temporary popularity or a diet designed to help you lose weight (especially fat) Examples are… • South Beach Diet (designed to get the body loosing weight and train the user to eliminate cravings), • The Acai Berry Diet (The acai berry diet is promoted as a weight loss plan that is high in antioxidants to improve general well being and boost metabolism) • The Atkins Diet(form of dieting that reduces carbohydrates – mostly from sugar, flour and high-fructose corn syrup), • Weight Watchers(Meals are planned to not exceed a certain calorie count for the day and there are resources for the dieters to plan their meals accordingly)

  8. Problems With the American Diet • Sugar - Americans consume more sugar today than ever before. The amount of sugar consumed per person every year in 2009 was 180 pounds--double what it was in 1900Read more: • High-fructose corn syrup is increasingly being used in foods instead of sugar because it is cheaper and more easily transported. • Fructosecan be metabolized only by the liver, which causes many serious issues for the body and leads to the metabolic syndrome, which is a cluster of conditions--hypertension, elevated insulin levels, excess body fat around the waist, abnormal cholesterol levels and the metabolic disorder dyslipidemia--that increases your risk of heart disease, stroke and diabetes. • Food processing refers to any process our food goes through after it is grown and harvested, from cooking to the addition of chemical ingredients. Refining refers to the breakdown of whole food into parts, such as the breakdown of grain into flour.

  12. Essential Nutrients • Protein - Should account for 10% to 20% of the calories consumed each day. Protein is essential to the structure of red blood cells, for the proper functioning of antibodies resisting infection, for the regulation of enzymes and hormones, for growth, and for the repair of body tissue. • Calories - Are needed to provide energy so the body functions properly. The number of calories in a food depends on the amount of energy the food provides. The number of calories a person needs depends on age, height, weight, gender, and activity level. People who consume more calories than they burn off in normal daily activity or during exercise are more likely to be overweight.

  13. Continued… • FAT- Should account for 30% or less of the calories consumed daily, with saturated fats accounting for no more than 10% of the total fat intake. Fats are a concentrated form of energy which help maintain body temperature, and protect body tissues and organs. Fat also plays an essential role in carrying the four fat-soluble vitamins: A, D, E, and K. • CHOLESTEROL - Intake should not exceed 300 milligrams a day. Individuals differ on their absorption of dietary cholesterol, what is important is one’s level of blood cholesterol. High blood cholesterol has been linked to the occurrence of atherosclerosis. Atherosclerosis is a buildup of fatty deposits in the coronary arteries and other blood vessels, and is a leading cause of heart attacks.

  14. Continued… • SODIUM- Intake is recommended to be less than 3,000 milligrams daily. One teaspoon of table salt contains about 2,000 milligrams of sodium. The difference between "sodium" and "salt" can be confusing. Sodium is a mineral found in various foods including table salt (sodium chloride). Table salt is 40% sodium. • POTASSIUM is essential for maintaining proper fluid balance, nerve impulse function, muscle function, cardiac (heart muscle) functionSources: bananas, raisins, apricots, oranges, avacadoes, dates, cantaloupe, watermelon, prunes, broccoli, spinach, carrots, potato, sweet potato, winter squash, mushrooms, peas, lentils, dried beans, peanuts, milk, yogurt, lean meats

  15. Continued • VITAMINS AND MINERALS- Are required for the regulation of the body's metabolic functions, and are found naturally in the foods we eat. Many foods are fortified in order to provide additional nutrients, or to replace nutrients that may have been lost during the processing of the food. Most people are able to obtain satisfactory nutrition from the wide selection of foods available in the United States.
