YOU ARE WHAT YOU EAT

- What is a Calorie?
Each food you eat not only contains more than one nutrient, but also a different number of calories. Calories are a unit of energy. Fat, protein, and carbohydrates provide calories, or energy as well as building blocks.
- What is a Carbohydrate?
Carbohydrates are sugars and starches. These substances are used by your body to create energy. After being eaten, they are broken down and are used as fuel. Carbohydrates are often described as simple or complex. Simple sugars are carbohydrates that are made up of sugar. Simple sugars are found in foods like candies, soft drinks, fruit juices, and fruit. Complex carbohydrates are found in foods like rice, potatoes, tortillas, and bread. Other foods which contain carbohydrates include carrots, corn, and bananas.


- What are Proteins?
Proteins are a major component of most tissues including muscles, bodily organs,

and cells. Proteins have to be eaten on a regular basis for your body to maintain itself. Animal sources of protein like meat, fish, dairy products, and eggs contain all nine essential amino acids. Non-animal sources of protein are beans, nuts, and some vegetables. Proteins are crucial in the re-building of muscle tissue.


- What are Vitamins?
Vitamins are important for the machinery of your body. They are chemical substances that help the body use energy, build proteins, make cells, and repair injuries. Certain vitamins help with specific parts of the body. Vitamin A is necessary for eyes, bones, and skin. Vitamin D is necessary to make bones, teeth, and allows your body to use the calcium that you eat. Vitamin E is important for healing wounds and to fight against bodily toxins. Vitamin C is important for fighting infection and for using the stored energy in your body. It is generally found in citrus fruits and other vegetables like tomatoes and peppers. The B vitamins are important for building blood cells, nerve cells, and are vital for many of your body’s chemical reactions. In general, a balanced diet can provide all the vitamins you need.


- What are Fats?
Fats are also necessary for health. Fat is an important source of stored energy in your body. Although fats are important, not all fats are as healthy for you as others. Eating too much saturated fat can increase your cholesterol and raise your risk of heart disease. Saturated fats come from meat, dairy products, and some kinds of vegetable oils. Unsaturated fats do not have as great an effect on cholesterol and do not increase the risk of heart disease as much. These fats are found in fish and in vegetable oils like olive, peanut, and corn oil. In general, it is a good practice to have most of your fat calories come from unsaturated fat. This means eating leaner meat, skim or low-fat milk, and avoiding fried foods.
