Macronutrient Outline INTRODUCTION Questions for students: 1. Have you heard of macronutrients? a. Breakdown work to help define what a macronutrient. 2. What have you heard about macronutrients? 3. Can you think of some foods that are good sources of these nutrients? What are macronutrients? Macronutrients are energy that comes from fats, carbohydrates and protein. o Our energy supply comes from macronutrients. o Macro = large and our bodies need large amounts of these nutrients to function and thrive. Food is mainly made up of 3 different nutrients: o Carbohydrates o Fats o Proteins Macronutrients are found in all foods in varying amounts. Water is found in all foods, but the foods that contain the most water are fruits and vegetables. o Water is not a macronutrient, but essential for every day living. Which macronutrients are good for you? All of the macronutrients are good. Carbohydrates, fats and proteins all give your body energy in the form of calories! Now we are going to learn some interesting facts about the four macronutrients. 1 CARBOHYDRATES QUESTION: Can anybody name any examples of carbohydrates? Carbohydrates are the body’s preferred and quickest source of energy. They provide the largest amount of energy that our body’s use when we are being active. They are also they only source of energy which feeds the brain o This is one why reason why it is so important to eat a nourishing breakfast! Food Sources Foods that are good sources of carbohydrates: o Fruits – bananas, apples, pineapples o Vegetables – potatoes, corn, peas (starchy) o Grains (especially whole grains) – especially whole grains: Brown rice Whole wheat bread Oats Whole wheat pasta o Dairy – milk, cheese, yogurt Foods that also have the macronutrient carbohydrates include candy, cookies, soda and sugary cereals. o These foods include added sugars and NO other nutrients o Not heart healthy because often contain a lot of unhealthy fat 2 FATS QUESTION: Can anybody name an example of fats? Fats are also used for energy. We primarily use energy from fat when we are performing low-energy activities, like sitting, walking leisurely, or playing video games. Having healthy fats in our diet is important to help keep us warm. It also helps us absorb important vitamins in our food that are called fat-soluble vitamins: o Vitamin A – help your eyes see at night and in color o Vitamin D – make your bones strong o Vitamin E – help to protect your cells against pollution in the environment o Vitamin K – and help with blood clotting There are healthy fats and unhealthy fats. o The unhealthy fats include trans fats and saturated fats. These fats are bad for you because they can clog up the arteries and veins that carry blood throughout your body and cause disease in your heart. o The healthy fats are unsaturated fats including polyunsaturated and monounsaturated fats. Food Sources Fats are mostly found in the milk, meat and beans, and oil food groups. Naturally found in nuts, seeds, and fatty fish like salmon: o These are very healthy fats and also a good source of protein. Also found in oils and butters: o Choose soft margarines over butter or shortening, and choose canola and olive oils. Found in fried foods, baked goods, and meats where the fat has not been removed: o Can hurt your heart over time. 3 PROTEIN QUESTIONS: Can anybody name any examples of protein? Protein helps providing building blocks for growing tall and developing muscles so it is important to eat a diet with adequate amount of protein. Proteins are used to build, repair, and maintain body tissue and muscles. Can be a source of energy. Food Sources Proteins are mainly found in the meat and beans food group. When choosing foods with proteins, it is important to choose lean proteins: o Extra lean ground beef, skinless chicken, beans, lentils, chickpeas, nuts and nut butters, and low-fat milk. o Lean proteins are low in unhealthy fat and are heart healthy 4 WATER Water is essential to live! o Without it our bodies would not live very long. Fortunately, water is everywhere! Water is found in all of the foods that we eat and all of the beverages that we drink. Water has a BIG JOB: o It carries the nutrients around in our body o It helps us breathe o Helps us keep a normal body temperature To get enough water, be sure to choose fresh fruits and vegetables often, and choose milk and water as a drink. o Some berries are made up of 85% water. o Fruit juice does contain some good nutrients, but it is also high in sugar so choose it less often. o Milk is made up of 87% water. CONCLUSION These macronutrients work best in our bodies when they are eaten together at a meal. Balanced meals include all of these macronutrients. 5
