Carbohydrates

Carbohydrates are one of the main types of food. Your liver breaks down carbohydrates into glucose (blood sugar). Your body uses this sugar for energy for your cells, tissues and organs.

Carbohydrates are called simple or complex, depending on how fast your body digests and absorbs the sugar. You get simple carbohydrates from fruits, milk products and table sugar. Complex carbohydrates include whole grain breads and cereals, starchy vegetables and legumes. Complex carbohydrates and some simple carbohydrates provide vitamins, minerals and fiber. Products made with refined sugar provide little nutrition. It is wise to limit these products.

Cancer

Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.
Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Treatment plans may include surgery, radiation and/or chemotheraphy.
