The JAMA study is a review and meta-analysis of 13 studies. Nine examined B6 intake, and four examined blood levels of PLP, the active form of B6. All the studies compared B6 status to cases of colorectal cancer.
In the new JAMA meta-analysis from Sweden’s Karolinska Institutet it showed that a higher B6 intake and blood PLP levels were linked to lower colorectal cancer risk, and the higher the PLP levels, the stronger the link.
B6 however is not only linked to reduced risk of colorectal cancer, it has been on the map for many years as ‘nature’s healer’.
In his book, “Vitamin B6 Therapy: Nature’s Versatile Healer.” Dr. John M Ellis explains that PLP is a coenzyme that activates many crucial enzyme systems. In fact, nearly 120 enzymes need B6 to function properly, and 19 out of your body’s 20 amino acids require B6.
That’s why it’s no surprise that B6 also plays a key role in many other health issues, including immune function, hormone function, and cognitive function, as well as the prevention of heart disease, depression, kidney stones, breast cancer, and prostate cancer.
The two best sources are bananas and chicken breast meat. Fish, red meat, beans, and a wide variety of other plant foods also contain B6, but Dr Ellis suggests that we still supplement our diet with even higher levels. As a water soluble vitamin it is non toxic because we cannot store it in our body.
