Natural CLA from milk products is a better cancer-fighter than CLA pills

Many people are not aware that there are many types of the cancer-fighting fat CLA, depending on minute differences in molecular structure. It now appears that, in test tube studies, the kind of CLA found in butter and animal fat is the most potent cancer-fighter. Human breast cancer cells were incubated in milk fat high in CLA or in an isolated form of CLA without any milk fat. The high CLA milk fat decreased cancer growth by 90 percent but the isolated CLA decreased it by only 60 percent. When the cells were incubated in linoleic acid, the kind of fat that is most abundant in grain and grain-fed animals, cell growth increased by 25 percent.

Milk products from 100 percent grassfed cows are as much as seven times higher in cancer-fighting CLA than ordinary milk and far lower in cancer-promoting linoleic acid.
