What Is Nutrition?. The study of how your body uses the food that you eat..

Nutrients. What are nutrients? A nutrient is a chemical substance in food that helps maintain the body..

Structure and function: Carbohydrates are sugars and starches that the body uses for ENERGY! PLANTS are the major source of carbohydrates in the food we eat..

Simple Carbohydrates. Sugars that are quickly digested and provide a BOOST of energy for the body Foods with LOTS of sugar: oranges, milk, cookies, candy.

Starches that are composed of many sugars linked together They provide the body with long-term energy since they are digested more slowly than sugars..

[image] Starch foods. 16. Sources of Carbohydrates.

Protein. Structure: Proteins are made from many amino acids connected together in different arrangements. Function: Provide the building materials your body needs to grow and repair itself.

Essential Amino Acids. 9 of the 20 amino acids are called essential amino acids because you must obtain them from the foods you eat since your body cannot make them..

Complete proteins: Foods containing all the essential amino acids Examples: fish, meat, eggs, milk, cheese Incomplete proteins: Foods that are missing some essential amino acids Examples: Legumes, nuts, whole grains.

Functions: ENERGY source for the body (more than carbs and proteins) Help protect and cushion vital organs as well as joints Insulate the body.

Fat. Structure: Fats belong to a group of organic compounds called lipids which are substances that do not dissolve in water. Fatty acids are the building blocks of fats..

Unsaturated fats: Contain fatty acids that are missing hydrogen atoms At room temperature, they are typically in liquid form..

Saturated fats: Contain fatty acids with the MAXIMUM amount of hydrogen atoms At room temperature, they are typically in solid form..

Diets with TOO MUCH saturated fat have been known to cause heart disease. Foods with a lot of saturated fat: beef fat, egg yolks, dairy products.

Fiber Non-digestible carbohydrates (chains of monosaccharides) Refining removes fiber from whole grains and other foods. Benefits Helps lower risk of Bowel irregularity Obesity Heart disease Cancer Diabetes mellitus.

Calories. What is a calorie? The energy obtained from carbohydrates, proteins, and fats is measured in units called calories..

Calorie Calculations. Carbohydrates 1g = 4 calories Protein 1g = 4 calories Fat 1g = 9 calories.

Sample Calculation. A slice of bread has 9g of carbohydrates, 2g of protein, and 1g of fat. Get out a piece of paper and see if you can do the calculations…...

9 grams carbohydrates x 4 calories/gram = 36 calories + 2 grams protein x 4 calories/gram = 8 calories + 1 gram fat x 9 calories/gram = 9 calories _________________________ Total calories = 53.

Calaroies Count. Normal Calorie require is 2000 kcal for men. Normal Calorie require is 1800 kcal for women. Depending upon the work calorie changes For less work 1800 kcal For medium work 2500 kcal For heavy work 3000 kcal..

Do you know the MOST IMPORTANT nutrient? It’s Water! 60%-80% of the human body is WATER!.

Function: Assists with the transport of materials in the body by making up most of the liquid part of blood (plasma), helps regulate body temperature, and helps break down food in the digestive system Food sources: vegetables, fruit, milk.

Micronutrients. Minerals and vitamins are called micronutrients since they are needed by your body in SMALL amounts. The minerals and most of the vitamins your body needs must be obtained from the FOODS you eat since your body cannot make them..

Micronutrients: Minerals. Minerals are INORGANIC substances that are required by your body in order to develop and grow properly. Some Important Minerals: Calcium Iron Potassium Magnesium.

Micronutrients: Minerals. Calcium Function: Helps build strong bones and teeth, regulates blood clotting Food sources: dairy products, leafy and green vegetables.

Micronutrients: Minerals. Iron Good sources: meat (especially lean red meat), liver and offal, green leafy vegetables, pulses (beans, lentils), dried fruit, nuts and seeds, bread and fortified breakfast cereals. Iron from meat sources (haem iron) is readily absorbed by the body. Vitamin C helps the body to absorb iron from other sources (non-haem iron)..

Micronutrients: Minerals. Potassium Function: Helps regulate fluid balance in the body, assists with the normal functioning of muscles and nerves Food sources: bananas, carrots, milk.

Micronutrients: Minerals. Magnesium Function: Involved in the metabolism of proteins and carbohydrates, assists with bone growth and proper muscle functioning Food sources: milk, meat, nuts.

Micronutrients: Vitamins. Vitamins: Group of complex compounds that help your body maintain normal metabolism, growth, and development Two Groups of Vitamins: Water-Soluble Fat-Soluble.

Water-Soluble Vitamins: Vitamins that dissolve in water and are NOT stored in your body for future use Vitamin B and Vitamin C.

Examples of Water-Soluble Vitamins: Vitamin C: Fights against infection, maintains healthy gums, strengthens and maintains blood vessel structure Food sources: citrus fruits, tomatoes, leafy vegetables.

Micronutrients: Vitamins. Vitamin B Complex/Folic acid: Helps prevent birth defects, and is needed in the formation of red blood cells and nucleic acids Food sources: beets, broccoli, avocado, turkey, bok choy, and lentils..

Fat-Soluble Vitamins: Vitamins that dissolve into and are transported by fat They can be stored in fat tissue, the liver, and the kidneys. Vitamins A, D, E, and K.

Examples of Fat-Soluble Vitamins: Vitamin A: Maintains good vision, promotes body cell growth, helps protect teeth Food sources: green vegetables, dairy products.

Vitamin D: Promotes the development of healthy bones and teeth Food sources: eggs, salmon, fortified breakfast cereal. Other sources include sunlight.

Functions of food. Carbohydrate = Energy giving foods: -cereals, sugars, fats, oils etc. Protein = Body building foods: -meat, milk, poultry, fish, eggs, pulses etc. Vitamins and minerals = Protective foods: -vegetables, fruits, milk, etc..
