1 CARBOHYDRATES

2 Carbohydrates Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products. They are one of the basic food groups; crucial for a healthy life. However, they are often maligned in trendy diets nowadays.

3 Carbohydrates Carbohydrates are macronutrients - they are one of the three main ways the body obtains energy, or calories. Macronutrients are essential for proper body functioning, and the body requires large amounts of them. All macronutrients must be obtained through diet; the body cannot produce macronutrients on its own. Carbs are found naturally in some forms of dairy and both starchy and nonstarchy vegetables. For example, nonstarchy vegetables like lettuces, kale, green beans, celery, carrots and broccoli all contain carbs. Starchy vegetables like potatoes and corn also contain carbohydrates, but in larger amounts. 

4 Carbohydrates  They are called carbohydrates because, at the chemical level, they contain carbon, hydrogen and oxygen.

5 *Carbohydrates provide fuel for the central nervous system and energy for working muscles. They also prevent protein from being used as an energy source and enable fat metabolism. *Carbohydrates are important for brain function. They influence mood, memory, etc., can be a quick energy source. In fact, the recommended daily amount (RDA) of carbohydrates is based on the amount of carbs the brain needs to function. *Fiber is essential to digestion. Fibers promote healthy bowel movements and decrease the risk of chronic diseases such as coronary heart disease and diabetes.

6 Carbohydrates are classified as simple or complex
Carbohydrates are classified as simple or complex. The difference between the two forms is the chemical structure and how quickly the sugar is absorbed and digested. Simple carbohydrates contain just one or two sugars, such as fructose (found in fruits) and galactose (found in milk products). These single sugars are called monosaccharides. Carbs with two sugars — such as sucrose (table sugar), lactose (from dairy) and maltose (found in beer and some vegetables) — are called disaccharides.

7 Simple carbs are also in candy, soda and syrups
Simple carbs are also in candy, soda and syrups. However, these foods are made with processed and refined sugars and do not have vitamins, minerals or fiber. They are called "empty calories" and can lead to weight gain, spikes in blood sugar level or sugar highs. Complex carbohydrates have three or more sugars. They are often referred to as starchy foods and include beans, peas, lentils, peanuts, potatoes, corn, parsnips, whole-grain breads and cereals. They provide more sustained energy.

8 Though carbs are often blamed for weight gain, the right kind of carbs can actually help you lose and maintain a healthy weight. This happens because many good carbohydrates, especially whole grains and vegetables with skin, contain fiber.  Good carbs are: *Low or moderate in calories *High in nutrients *Devoid of refined sugars and refined grains *High in naturally occurring fiber *Low in sodium *Low in saturated fat *Very low in, or devoid of, cholesterol and trans fats
