CLA and Cancer
Studies have suggested that a high dietary intake of
CLA may decrease the risk of
colorectal cancer and, perhaps, even
breast cancer. However, it is not known if taking CLA supplements is as effective as obtaining CLA through dietary means.
Some forms of CLA may affect muscle and fat cells by decreasing fat storage and possibly increasing muscle mass. CLA may also help suppress the appetite. Additionally, there is some evidence that CLA may be toxic to cancer cells. There are different forms (or isomers) of CLA, and some seem to be more beneficial than others. In fact, synthetic CLA (the kind usually found in supplements) usually has much higher levels of the form of CLA that seems to be responsible for some of the negative effects of CLA.
CLA is safe for children when consumed in normal food amounts. However, it is not known if CLA supplementation is safe for children, as the long-term effects of using CLA supplements are not known.
