#11. Carotene

There are now fourteen ongoing prospective randomized studies sponsored by the National Cancer Institute that look at the anticancer potential of carotene in high risk patients. Over thirty studies have shown that people who consume foods with high amounts of carotene have a low risk for developing cancer.

Carotene has also been shown to be the most potent antioxidant, i.e., which neutralizes free radicals and also single oxygen radicals. In addition, it has been shown to be one of the more important enhancers of the human immune system and can also reverse precancer conditions.

Food

Carrots, sweet potatoes, yams, pumpkins, squash, kale, broccoli, cantaloupe

Protective Action

Neutralizes free radicals and singlet oxygen radicals; enhances immune system; reverses pre-cancer

#10. Indoles

Indoles, found in the cabbage family, can destroy or otherwise inactivate estrogen. Estrogen is known to initiate new cancers, especially breast cancer.

Food

Cabbage family: cabbage, broccoli, cauliflower, mustard green, etc.

Protective Action

Destroys estrogen, known to initiate new cancers, especially breast cancer.

#9. Isoflavones

This is one of the more exciting areas of cancer prevention. Isoflavones, predominantly found in legumes, have been shown to inhibit or block estrogen receptors thereby prohibiting the cell from its normal cellular function without estrogen.

Isoflavones also inhibit estrogens from being effective in the first place, and have been shown to destroy certain cancer gene enzymes that can propagate and transform a normal cell into a cancer cell.

Food

Legumes: beans, peas, peanuts

Protective Action

Inhibits estrogen receptor; destroys cancer gene enzymes; inhibits estrogen.

#8. Lignans

ignans are predominantly found in flaxseed, walnuts, and fatty fish. Each of these is an excellent source of omega-3 fatty acids, which are known to inhibit the production of prostaglandins, hormones that modulate cell metabolism.

Numerous studies have shown that omega-3 fatty acids have been used to reduce cholesterol, hypertension, heart disease, and the risk for developing breast cancer, rheumatoid arthritis, and multiple sclerosis. Lignans have also been shown to inhibit the action of estrogens on cells that are responsive to estrogen.

Food

Flaxseed, walnuts, fatty fish

Protective Action

Inhibits estrogen action; inhibits prostaglandins, hormones that cause cancer spread.

#7. Polyacetylene

Polyacetylene, mainly found in parsley, inhibits the action of prostaglandins and destroys a potent carcinogen called benzopyrene.

Food

Parsley

Protective Action

Inhibits prostaglandins; destroys benzopyrene, a potent carcinogen.

#5. Quinones

Quinones are mainly found in rosemary, and these chemical agents have been shown to inhibit carcinogens and co-carcinogens, chemicals that help carcinogens work more effectively to cause cancer.

Food

Rosemary

Protective Action

Inhibits carcinogens or co-carcinogens.

4. Sterols

Sterols are mainly found in cucumbers, especially the skin of cucumbers. Sterols have been shown to decrease cholesterol; and by lowering the cholesterol, you lower most of the fat content that is linked and associated with multiple cancers, including colon and rectal cancer, breast cancer, prostate cancer, and cancer of the uterus, endometrial cancer.

Food

Cucumbers

Protective Action

Decreases cholesterol.
