Conjugated Linoleic Acid
(CLA)- The Fat of the Future?
Daena C. Wichell
Conjugated linoleic acid (CLA) is a
group of positional and geometric isomers of linoleic acid. In our diet, CLA is
predominantly found in ruminant meats and dairy products and, in recent years, has been
found to possess several unique characteristics. Using various animal models, CLA has been
found to act as an anticarcinogen, reduce atherosclerotic progression, increase feed
efficiency, alter body composition and affect immune function. Its anticancer properties
have received a great deal of attention because these effects are present at levels that
could potentially be achieved in the diet. Difficulties exist, however, in extrapolating
these health benefits to humans because virtually all animal studies to date have utilized
diets which have a macronutrient composition that is not representative of what humans
eat. Specifically, the level and composition of fat fed to animals in these studies are
not consistent with current intake or recommendations by various nutrition agencies.
The current study will examine whether CLA exerts its anticarcinogenic effects in the
context of current human fat recommendations and actual North American dietary fat
consumption patterns. In addition, this study will examine the possible effects of CLA on
various components of the immune system as a mechanism underlying its antitumorigenic
properties. Both branches of the immune system- acquired and innate- are involved in our
defense against tumors. Previous studies have shown that dietary fat alters immune
function. Since CLA is a fat and has also been shown to affect immune function it seems
plausible that its anticancer activities may be mediated through the immune system.
Much remains to be learned about CLA and the mechanism(s) whereby it may reduce tumor
development. Greater insight into such mechanisms will provide valuable information about
the process of tumor development and the numerous roles of lipids in the body. This work
will contribute to our understanding of the effects of CLA on immune function and if CLA
is indeed the "fat of the future".
Key Words: CLA, dietary fat, anticarcinogens, immune functions, fat of the future
