- 1. Why Do We As Humans Eat? Made by Dragan Angov 2-C
- 2. The Role of Food • Food is a necessity in life, like water and air. • Your food choices affect all 3 sides of your health triangle. • Ex. not eating breakfast. • Physical- Low on energy • Men/Emo- Trouble focusing • Social- Grumpy and irritable
- 3. • Nutrients: are substances in food that your body needs. • They help build new tissue, repair damaged cells and produce energy. Food, Nutrients and Nutrition • Nutrients nourish the body in two ways: • 1) They provide energy (proteins, carbohydrates, and fats) • 2) They help your body run smoothly (vitamins, minerals, and water). • Nutrition: the process by which your body takes in and uses food.
- 4. Appetite and Hunger • Appetite: the psychological desire for food. • aroma of freshly baked bread makes you crave bread when you are full. • Hunger: the body's physical need for food. • It is important to learn the difference between appetite and hunger so you can make healthy food choices.
- 5. • Emotions can also influence the way we eat. • If someone is feeling sad or stressed out they might turn to food to feel better. Food and Emotions
- 6. Meeting Nutrient Needs • All bodies need the same nutrients, but not the same amount..Depends on age, gender and activity level • Teens vs Adults, Olympians vs Average Joes • Most people in the US get enough food to eat but don't get the nutrients they need. This is because of foods that are high in fat and added sugar. • We want to get the most nutrition out of our calories – nutrient dense • Eating low-nutrient foods, along with overeating can lead to obesity, heart disease and cancer.
- 7. How your body uses nutrients?: • good nutrition can affect your lifelong health by helping you avoid weight gain – type 2 diabetes • The energy provided by food is needed by teens for growth and activity • To heal, build/repair tissue • To transport oxygen to cells • To regulate body functions
- 8. • Scientists have found more than 40 different kinds of nutrients. • The six main categories of nutrients are: 1. Carbohydrates 2. Proteins 3. Fats 4. Vitamins 5. Minerals 6. Water Nutrients and Nutrition • Eating a variety of healthy foods will help you get the nutrients you need. • Nutrients that provide energy are carbs, fats and proteins
- 9. • Carbohydrates: sugars and starches found in foods which provide your body’s main source of energy • Made up of sugar molecules • Nutritionists suggest that 45%-65% of daily calories should come from carbs. Carbohydrates
- 10. Simple vs. Complex Carbohydrates Two types of carbs: 1. When molecules stay separate it forms simple carbs. 2. When molecules join together they form long chains called starches or complex carbs. - beans
- 11. • Fiber: a tough complex carbohydrate that the body cannot digest. • As fiber moves through the digestive system it pushes other food particles along. • fruits, veggies and grains • Should contain 10-19 percent of your daily value to be a good source Fiber
- 12. • Proteins: are nutrients your body uses to build, repair and maintain cells and tissues. • They are made up of chemical building blocks called amino acids (20 that the body use). • Muscles repair themselves and build new tissue after a workout. • Proteins also help fight sickness and disease because parts of our immune system are made of proteins. • Complete proteins contain all 9 essential amino acids. Examples are animal based meats Proteins
- 13. Fats • Saturated Fats: are fats that are solid at room temperature. • Ex, Butter, cheese, and fatty meats. • Eating too many saturated fats increase your risk of heart disease. • Unsaturated Fats: are fats that are liquid at room temperature. • Ex, Olive oil, nuts, and avocados • Promote healthy skin and normal cell growth and they carry vitamins to where they are needed in the body. • can actually help lower your risk for heart disease • Help maintain healthy skin and hair
- 14. • Cholesterol is both a fatlike substance found in food and a fatty substance in the blood. • Cholesterol in food only comes from animal-based foods like eggs, meat, poultry, fish and dairy products. • Eating too much food cholesterol can raise blood cholesterol, clog arteries and lead to heart disease. Cholesterol
- 15. • Vitamins: compounds found in food that help regulate many body processes • Minerals: elements found in food that are used by the body. Vitamins & Minerals There are two categories of vitamins: 1. Water-Soluble dissolve in water and your body cannot store them. Ex: Vitamin C and B Complex 2. Fat-Soluble are stored in the body until needed. Ex: Vitamin A, D, E & K.
- 16. Vitamins & Minerals • Vitamin A- healthy skin and vision • B Vitamins- healthy nervous system, produce and maintain new cells. • Vitamin C- healthy teeth, gums and bones. Helps health wound and fight infection. • Vitamin D- strong bones and teeth, helps absorbs calcium. • *****Vitamin E- helps protect cells. Builds up in the body • ******Calcium- build and maintain strong bones and teeth. osteoporosis • Fluoride- strong bones and teeth, prevents tooth decay. • Iron- Hemoglobin in blood cells. • Magnesium- strong bones; releases energy for muscles. • Potassium- regulate fluid balance in tissues; promotes proper nerve function. Functions in the body Sources from food • Dark leafy greens; dairy products; eggs; yellow-orange fruits and vegetables. • Poultry; eggs; meat; fish; whole- grain breads • Citrus fruits; strawberries; mangoes; tomatoes; broccoli; potatoes • Milk; salmon; egg yolks; liver • Dark leafy greens; fish; nuts; seeds; vegetable oils. • Dairy products; dark leafy greens; canned fish with edible bones. • Fluorinated water; fish with edible bones. • Red meat; poultry; dry beans; nuts; eggs; dried fruits; dark leafy greens. • Dark leafy greens; beans and peas; whole-grain breads and cereals. • Bananas; oranges; dry beans and peas; tomato juice.
- 17. Water A nutrient that is needed in large amounts • Moves food through the digestive system • Digests carbs and proteins • Transports nutrients and removes wastes • Storing and releasing heat • Cooling the body through perspiration • Cushioning eyes, brain and spinal cord • Lubricating the joints "If it were possible to drain all the water from a 160 lb. man, his dehydrated body would weigh only 64 lbs."~Bethesda Health & Fitness Center
- 18. Guidelines for Healthy Eating • MyPyramid Food Guidance System: is an interactive guide to healthful eating and active living. • Created by the United States Department of Agriculture (USDA). • The pyramid is divided into six sections: • The 5 main food groups (grains, vegetables, fruits, dairy, meat/beans) are labeled with colors • The 6th section represents fats and oils. • It also has a figure walking up steps to show that you need exercise everyday to stay healthy.
- 19. USDA replaced the MyPyramid in 2011 with Choose My Plate http://www.choosemyplate.gov/
