A presentation on foods that help reduce the risk of getting cancer and dietary risk factors.

Why am I telling you about foods and cancer? Most people are not aware of how they can lessen the risk of obtaining cancer.

30% of all cancers are due to tobacco use, and between 35 to 50% of all cancers are associated with diet. These cancers are preventable.

Fiber Dr. Dennis Burkitt Colon Cancer Western Nations Animal Products Plant Products

How Does Fiber Work To Prevent Cancer? Moves food quickly through the digestive tract. Pulls in water. Water and fiber make carcinogens more diluted. Binds to Bile acids.

Fiber and Breast Cancer Studies show that breast cancer is less common to those that have a diet high in fiber. Estrogens –Normally secreted into the digestive tract. –High levels are associated with breast cancer.

Whole grains, beans, peas, lentils, vegetables, and fruits are the best sources of fiber. Foods should also be closest to their natural state, which is unrefined and unpeeled, to have the highest amount of fiber. They take 26 nutrients out of whole wheat to make white flour, but they only add 4 back.

Whole Wheat Excellent source of fiber. Contains insoluble fiber. Experts suggest that you should have around 6-11 servings of grains a day. –Of this, you should have 3 or more servings of whole grains.

Dietary Fat Populations with the highest levels of fat consumption also have the highest death rates from breast and colon cancer. Risk and Survival Rates Animal Fat vs. Vegetable Fat

Fat and Cancer Increases hormone production. Stimulates bile acid production. The average American diet is about 37% fat. Fat intake should be below 30% in order to prevent cancer.

Vegetables! Vegetables are low in fat and high in fiber and they contain many cancer-fighting substances.

Sprouts Alfalfa Sprouts –Contain Phytoestrogens –Including Lignans Induction of cancer cell differentiation, inhibition of tyrosine kinase, and suppression of angiogenesis

Broccoli Broccoli has multiple cancer-fighting properties High in Fiber. Phytochemicals –Indoles Medium Size Stalk –220% of daily value of Vitamin C –15% of daily value of vitamin A – Beta Carotene.

Carrots Contains Cartenoids –Acts as antioxidants Contains Beta- carotene –traps free radicals to help prevent cancer

Cauliflower Indoles –Turns off estrogen hormones Sulforaphane –Immune system Folic Acid –Cell division –Immune system Vitamin C –Antioxidant properties –Immune system

Spinach High Amounts of Vitamin A and K –Helps regulate cell division and communication –Immune System Also contain the cartenoid Beta- Carotene –Anti-oxidant properties

Vitamins and Cancer Beta-carotene –Lung, bladder, mouth, larynx, esophagus, and breast cancers Vitamin C –Cancers of the mouth, larynx, esophagus, and stomach. Selenium –Prostate, Colon, and Lung Cancers.
