Better Fat Loss, Fight Cancer, and Prevent Heart Disease with Trans Fats

Who Else Wants To Know How To Get Better Fat Loss, Fight Cancer, and Prevent Heart Disease with Trans Fats

Trans fats have been condemned to hell by the media, and while man made trans fats are definitely not good for you, not ALL trans fats are created equal. In this article I will show you how specific trans fats will give you better fat loss, help you fight cancer, and prevent heart disease.


Conjugated Linoleic Acid (CLA) is a type of trans fat that has been studied extensively due to its huge potential for helping with obesity, cancer, and heart disease.


Trans fats are produced naturally in the stomachs of ruminant animals such as deer, moose, kangaroo (not a true ruminant, but an exceptional source of CLA), bison, beef, sheep, and goats.


One particular trans fat called t-10, c-12 CLA has been shown to reduce fat mass and increase lean muscle weight in a number of different studies, while a number of other studies have shown the trans fat called c-9, t-11 CLA has effects that reduce inflammation and risks of cardiovascular disease.


Interestingly there are other studies that show the direct opposite to be true. Does this even surprise you? The one thing we should all know by now is that whatever science studies and proves is true, will often be found to be false in a subsequent study. This has happened numerous
times with studies on vitamins.


However, when both types of trans fat CLA are studied together, most studies showed reduced body fat mass, increase lean muscle tissue, and reduced incidencs of both cancers and heart disease markers.


The key element is that when science tries to isolate the effects of different substances, often the study methods influence the outcomes. But left to it's own devices, the human body will reap the benefits without experiencing the negative effects noticed in the studies.


Interestingly, when studies of the effects of CLA consumption involve its natural form INSTEAD of taking it as a nutritional supplement, once again, the health benefits are shown, with little to no adverse affects. (see I'm not writing this to sell any magic pills or potions to you!)


Another very important fact is that grass-fed animal meats contain between 300%-500% more CLA than their supermarket grain-fed counterparts.


So don't touch the stuff you find at your regular supermarket, unless it is clearly marked to be "GRASS-FED". If your local supermarket doesn't carry grass-fed meats, try your local butcher or health food stores.


One final study that I'd like to bring to your attention found that mothers who ate and drank organic grass-fed cows' meat and milk had 50 % higher rumenic acid (a type of trans fat) levels in their breast milk. In humans, rumenic acid is converted into CLA, which is responsible for the above noted effects.


The jury on this one, as always, is clear. Eat what nature provides for you in the form it exists in in nature, and you will reap the benefits. Try to put it into a magic pill, and you can't be sure that you will get the effects you seek, and you may even get some you don't want.


Over time science will study various nutritional substances and show that one thing works and another doesn't, and then later their studies will show the opposite. The incredible human body always knows exactly how to use all the nutrients in exactly the right way to get the best possible health benefits.


When selecting foods always choose organic if possible, choose fresh whenever possible, choose pasture raised forage and grass-fed meats, and in general, be wary of foods that require a big label that tries to convince you of their health benefits.
