Oxford Scientists: Conjugated Linoleic Acids Kill Cancer Cells
Numerous journals have reported that conjugated linoleic acids (CLAs) have ‘anti-proliferative qualities’ for cancer cells. CLAs are dietary fatty acids, an Omega 6, that have both anti-mutagenic and anticarcinogenic qualities. For men with prostate cancer (currently the second most prevalent type of cancer in Western countries) this is great news. While scientists can’t figure out exactly why CLAs help to dissolve cancerous cells and keep them from multiplying, the news is still helpful and positive.
“The aims of this study were to examine the anti-proliferative effects of different concentrations of a commercial preparation of conjugated linoleic acids (CLA) mixture of isomers [cis-9, trans-11 CLA (c9,t11 CLA): trans-10, cis-12 CLA (50:50)] and their constituent isomers on PC-3, a human prostatic carcinoma cell line, and to study their effects on gene expression (mRNA and protein levels) of different enzymes and oncoproteins involved in oncogenesis and progression of prostate cancer.”
CLAs also stop estrogen signaling which can cause tumors to grow in breasts, causing lead to breast cancer.
“Conjugated linoleic acid (CLA), a mixture of positional and geometric isomers of linoleic acid found in dairy products and meat from ruminants, has been widely shown to possess anticarcinogenic activity against breast cancer both in vitro and in animal models…Taken together, these findings demonstrate that CLA compounds possess potent antiestrogenic properties that may at least partly account for their antitumor activity on breast cancer cells.”
Yet another study found that CLAs can help stop colon cancer by affecting protein kinase C (PKC) and nuclear factor kappa B (NF-kappaB) signaling pathways.
“Conjugated linoleic acid (CLA) has anti-carcinogenic effects in a variety of cancers including colon cancer….In conclusion this study indicates that chronic CLA treatment inhibits DCA-induced PKC and NF-kappaB activation in colon cancer cells. These data suggest mechanisms by which CLA may influence the course of colonic cancer.”
CLAs can also lower high blood pressure, reduce bad cholesterol, and even regulate insulin in diabetics. It is sometimes also used to aid in weight loss since it helps to regulate blood sugar levels, and thus stop sweet cravings. Additionally, CLAs reduce food allergies in many people.
CLAs are normally found in dairy products, but there are other ways to consume them (since much of our dairy has been contaminated with hormones and antibiotics). Grass fed meat also contains CLAs (again, make sure you get the antibiotic and hormone-free, non-factory farm meat) as well as some vegetable oils and fortified eggs.
If you want to reduce your chance of multiple cancers, lose weight, regulate metabolism and more, you can start eating your cheese, yogurt, and other organic dairy products. They just might save your life.
