Scene 12 (1m 31s)

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

Scene 13 (1m 45s)

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..

Scene 14 (1m 53s)

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.

Scene 15 (2m 8s)

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..

Scene 16 (2m 10s)

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

Scene 17 (2m 35s)

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.

Scene 18 (2m 41s)

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..

Scene 19 (2m 47s)

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.

Scene 20 (2m 56s)

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

Scene 21 (3m 5s)

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..

Scene 22 (3m 14s)

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

Scene 23 (3m 19s)

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

Scene 24 (3m 28s)

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.

Scene 25 (3m 43s)

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.

Scene 26 (3m 55s)

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

Scene 27 (4m 5s)

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

Scene 28 (4m 12s)

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…...

Scene 29 (4m 29s)

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.

Scene 30 (4m 32s)

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..

Scene 31 (4m 42s)

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

Scene 32 (4m 44s)

Scene 33 (4m 52s)

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..

Scene 34 (5m 2s)

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.

Scene 35 (5m 5s)

Scene 36 (5m 7s)

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)..

Scene 37 (5m 9s)
