NUTRITION for 6 TH CLASS Making Healthy Decisions
WHAT IS NUTRITION? Nutrition is the science of food, the nutrients in foods and how the body uses those nutrients. It includes the process of ingestion, digestion, absorption, metabolism, transport, storage and excretion of those nutrients. It also includes the environmental, psychological and behavioral aspects of food and eating.
NUTRIENTS There are six classes of nutrients include: carbohydrates, proteins, vitamins & minerals, fats and water. Now were going to look at where we get these nutrients from and what they do for our bodies.
CARBOHYDRATES What are carbohydrates? Your body uses carbohydrates (carbs) to make glucose which is the fuel that gives you energy and helps keep everything going. Your body can use glucose immediately or store it in your liver and muscles for when it is needed The healthiest sources of carbohydrates are; Fruits Vegetables Breads, cereals, and other grains
PROTEIN What is Protein? Proteins are part of every cell, tissue, and organ in our bodies. These body proteins are constantly being broken down and replaced. The protein in the foods we eat is digested into amino acids that are later used to replace these proteins in our bodies Protein is found in the following foods: meats, poultry, and fish legumes (dry beans and peas) tofu Eggs & milk nuts and seeds
VITAMINS AND MINERALS Vitamins are organic substances (made by plants or animals) Minerals are inorganic elements that come from the earth; soil and water and are absorbed by plants. Animals and humans absorb minerals from the plants they eat. Vitamins and minerals are nutrients that your body needs to grow and develop normally Each vitamin and mineral have a unique job; Eg. Vitamin D helps your body absorb the amount of calcium (a mineral) it needs to form strong bones. The best way to get enough vitamins is to eat a balanced diet with a variety of foods. You can usually get all your vitamins from the foods you eat. u eat. - V -
WATER Where do I get the water I need? Most of your water needs are met through the water and beverages you drink. You can get some fluid through the foods you eat. For example, broth soups and other foods that are 85% to 95% water such as celery, tomatoes, oranges, and melons
WHAT DOES WATER DO IN MY BODY? What does water do in my body? Water helps your body with the following: Keeps its temperature normal. Lubricates and cushions your joints. Protects your spinal cord and other sensitive tissues. Gets rid of wastes through urination, perspiration, and bowel movements.
HOW CAN I INCREASE MY WATER INTAKE? Under normal conditions, most people can drink enough fluids to meet their water needs. If you are outside in hot weather for most of the day or doing vigorous activity, you may need to increase your fluid intake. If you think you're not getting enough water each day, the following tips may help: Carry a water bottle for easy access when you are at work or running errands. Freeze some freezer-safe water bottles. Take one with you for ice-cold water all day long. Choose water instead of sugar-sweetened beverages. This tip can also help with weight management. Substituting water for one 20-ounce sugar-sweetened soda will save you about 240 calories. Choose water instead of other beverages when eating out. Generally, you will save money and reduce calories. Give your water a little pizzazz by adding a wedge of lime or lemon. This may improve the taste, and you just might drink more water than you usually do
WHY DO I NEED FAT?? Fats are essential for normal body function. Some fats are better for you than others. Trans fats, saturated fats and cholesterol are less healthy than polyunsaturated and monounsaturated fats.
FRUIT & VEGETABLES "Eat your fruits and vegetables." Your parents probably tell you this all the time! Research shows why it is good advice: Healthy diets rich in fruits and vegetables may reduce the risk of cancer and other chronic diseases. Fruits and vegetables also provide essential vitamins and minerals, fiber, and other substances that are important for good health. Most fruits and vegetables are naturally low in fat and calories and are filling. Did you know that ½ of your plate each meal should be fruits and vegetables?
