Cancer fighting foods are relatively common. Eating a diet for cancer may mean making a few simple adjustments to your existing diet. Foods that fight cancer are readily available at supermarkets and can be delicious additions to your favorite recipes.
I heard a joke the other day that the four food groups are alcohol, sugar, caffeine and fat. For some that is sadly true. Many of the things we put into our mouths cannot be considered food. They have little resemblance to anything in nature. Additives, preservatives, and the like can act in the body to burden the liver, raise blood pressure and even stimulate cancer cell growth. Food - fruits and vegetables, grains and nuts - are incredibly un-sexy nowadays though they provide all the nutrients the latest 'discoveries' tell us we need to be healthy. 'Food' has the ability to replenish nutrient shortages, hydrate and detoxify the body, build blood, muscle and bone, create natural energy, boost immunity, fight infection and build the enzymes needed to repair DNA. Breast cancer begins with damaged DNA. So, whatever protection we can provide to our DNA is worth the effort.
Let Your Food Be Your Medicine. Wiser words were never spoken. Even the common apple is chock full of quercetin, a natural chemical that has been shown to reduce the risk of heart disease and cancer. As if understanding this principle, the Food and Drug Association considers botanicals to be food products. Proper food choices can delay the onset of cancer through myriad pathways (i.e. enhancing DNA repair), protect normal cells from damage done by chemotherapy and radiation, decrease side effects and destroy cancer cells.
Food Superstars for Maintaining Breast Health and Fighting Cancer
Mushrooms
Maitake mushroom literally means 'dancing mushroom'. Historically, Maitake was so rare that people danced when they found it. Along with other mushrooms in the family (Cordyceps, Coriolus, etc), Maitake contains natural sugars which stimulate cancer fighting NK and T cells.
Turmeric
The turmeric plant gives curried dishes their distinctive yellow color and contains a potent antioxidant called curcumin. Curcumin has multiple cancer fighting mechanisms including downregulating COX-2 (inflammation), EGFR and HER-2 (proliferation triggers). Chronic inflammation has been shown to progress to cancer particularly in the stomach and bladder.
Broccoli, Cauliflower, Brussel sprouts
Broccoli, Cauliflower, Brussel sprouts belong to the Brassica family and contain the chemopreventive agent brassinin. Chopping and light steaming make broccoli's bioactive compounds more available. Organically grown cruciferous vegetables show higher levels of phytonutrients than conventionally grown.
Grapes
Grapes are one of the most commonly consumed foods worldwide. Grape seeds, along with peanuts and mulberries, contain resveratrol. Resveratrol has been shown to possess chemopreventive and anti-tumor properties in laboratory studies.
Leaf Vegetables (spinach, kale)
Doctors recommend getting sufficient amounts of folic acid during pregnancy to protect against anemia. Following this recommendation before and after pregnancy as well can improve breast health. Folate (dietary methyl) is a nutrient that helps to regulate DNA methylation. This accessory modification then partly controls which genes are switched on or off. It is important that the so called 'tumor suppressor genes' such as BRCA-1 are properly regulated. Thus genes can be influenced by compounds in the foods we eat.
Onions and Garlic
Onions and garlic contain allyl sulfides—compounds that make cells sensitive to the stress of cell division. Because cancer cells divide so frequently they undergo more stress and create more stressors. They are thus more susceptible to damage by allyl sulfides. The effective compounds are best concentrated at home by crushing or finely chopping the garlic and waiting about 15 minutes before cooking.
Soy
Soy has been associated with inhibition of breast cancer cells in some but not all laboratory studies. Soy (tofu, tempeh, etc.) contains phyto estrogens which mimic the body's natural estrogen. It is believed that its tumor inhibiting properties are invoked by binding to estrogen receptors and blocking their growth stimulatory signals.
Herbs
Special foods, called herbs, typically have little nutritive value but possess potent functional characteristics. Pharmaceutical companies have already harnessed the Pacific Yew tree and Periwinkle plant to create drugs like Taxol and Oncovin. Several other species have significant potential in cancer prevention and treatment.
- Astragalus has a long history of use and seems to enhance the immune system by restoring suppressed immune T cell function.
- Baikal skullcap (Scutellaria baicalensis) inhibits cancer cell proliferation in research studies.
- Mushrooms (Codyceps, Coriolus, Maitake, etc.) show immunomodulating effects. They contain sugars such as polysaccharide-K (PSK) which have been used in Japan as an adjunct to chemotherapy.
- Graviola (Annona muricata) may also be known as soursop. These tropical plants contain the Annonaceous acetogenins which stimulate apoptosis (programmed cell death) and seem to convey Graviola's anti-tumor abilities. Studies also demonstrate Graviola's capacity to inhibit the removal of cancer drugs from the cells.
Breast cancer is a complex health challenge and should be approached with the help of a qualified health practitioner.
Editor's note:
"Foods that fight Cancer" should not be construed as "foods that TREAT cancer'. These are two completely different things. This article is NOT a treatment plan for cancer. Rather, it identifies compounds found in the foods we should be consuming anyway, as part of the 5-9 a day recommendation, that have been found to have an effect on cancer. This is a very important point.
