Anthelme Brillat-Savarin said: "Tell me what you eat and I will tell you what you are". It is from this quotation that we get the phrase, "You are what you eat." It is very true but probably not in the way that you imagine. The majority of people in the western world consider polyunsaturated fats and products containing such fats as sunflower oil, vegetable oil and margarine as good for you. Conversely the received truth is that food containing saturated fats such as butter, animal fat and coconut oil are very bad for you. New research is beginning to show that the opposite is true.

For many years the media, doctors and the government has been telling us to cut saturated fats out of our diets. Instead, these authorities claim, we should be eating polyunsaturated fats. As a result all foods, even fast food and junk food have switched to using polyunsaturated fats. We believe these fats reduce cholesterol and make us healthier.

Do they? Obesity is worse than ever. Heart disease and cancer are still very much with us.

The reason is bad science. The key to a healthy diet is not to cut out all fats from your diet. If you did you would feel depressed and lethargic. Rather the answer lies with the thyroid gland. Certain fats suppress the thyroid gland and others increase thyroid gland activity. Saturated fats such as virgin coconut oil and organic butter increase thyroid activity. This leads to the body being able to break down cholesterol and being able to produce hormones that fight aging and disease. In contrast, fats such as those made from corn, soy, sunflower and safflower reduce thyroid activity and cause cholesterol build-up and a weakening of the immunity system.

Here are two pieces of evidence. Have you been to Thailand? If you have you must have struck by how thin and healthy people are. Thais are physically strong and have a low rate of cancer and heart disease and yet their diet is high in the saturated fat from organic coconut oil. The same is true of Polynesians. Until recently their diet was comprised of up to 60% coconut oil. This diet high in saturated fat didn't produce an epidemic of coronary complaints. It is only since western food items containing polyunsaturated fats found their way onto the shelves in local shops that heart disease has become a problem for some islanders foolish enough to stray away from a traditional diet.

The second piece of evidence comes from lab experiments. In one famous experiment lab rats were divided into two groups and given cancer inducing injections. Amongst those rats fed on corn oil 32% of the rats developed cancer, but amongst the rats fed on coconut oil only 3% developed cancer. In a similar way, farmers in the 1940s in America tried injecting their cows with thyroid suppressants to make the cows develop more fat. The results were disastrous many cows died prematurely of disease. The answer came in the form of soy feed which suppresses thyroid activity without threatening the immediate life of the cow. It is a technique that is still prevalently followed today.

So if you don't want to end up over weight like the cows or with cancer like the rats you should consider ignoring the polyunsaturated fat propaganda and turn to using saturated fat for cooking. It is something that has stood millions of people in the world in good stead and should not be dismissed lightly.
