Does fat make us Fat?

Everyday in the news is some information about the fat.

We all need it, we all eat it.

What are the facts?

Here’s a simple guide to fats, the good, the bad and the ugly.

First realize that fats are a necessary part of any diet. We need fats to make hormones, build and repair tissues, and for energy. Gram per gram, fat provides about more than twice the energy of carbohydrates (9 calories per gram vs 4 calories per gram for carbs). Fats also help us absorb certain vitamins and satiates our appetite more than carbs or protein.

But there really are good fats and bad fats and the Cliff notes version of this column is this — if a fat is solid or semi-solid at room temperature, you should avoid it.

Most dietary fats fall in to three categories: Saturated fats, polyunsaturated fats, and mono unsaturated fats.

A meta-analysis published in the American Journal of Clinical Nutrition (March 2010 9(3)535-546), combined the relative risk rates of cardiovascular disease (CVD) from 21 studies. This Mega-analysis represents almost 350,000 subjects whose diets and health outcomes had been followed for 5 to 23 years. The conclusion: “There is no significant evidence concluding that saturated fat is associated with an increased risk of CVD.

Sources of saturated fat: Beef, beef tallow (fat), dairy, palm oil, coconut oil.

Saturated fats? roles in the body include: [1]

? They constitute at least 50% of our cell membranes and give our cells integrity.
? They play a vital role in the health of our bones.
? They lower Lp(a), a substance in the blood that is said to indicate proneness to heart disease.
? They protect the liver from alcohol and other toxins like Tylenol (Acetaminophen).
? They enhance the immune system.
? They are needed for proper utilization of essential fatty acids.
? Stearic acid and palmitic acid, both saturated fats, are the preferred energy source of the heart. This is why the fat around the heart muscle is mainly saturated. The best sources for palmitic acid are beef, butter and palm oil.
? Short and medium chain saturated fatty acids have strong antimicrobial properties. They help protect us from harmful microorganisms. The best sources are tropical oils such as coconut oil and palm oil.

A recently published meta-analysis looked at 347,747 subjects in twenty-one studies to summarize the evidence related to the association of dietary saturated fat with risk of coronary heart disease (CHD), stroke, and cardiovascular disease. During the 5 – 23 year follow-up 11,006 of the almost 350,000 subjects developed CHD or stroke.

Conclusion: Saturated fat consumption was not associated with an increased risk of heart disease or stroke
(American Journal of Clinical Nutrition, Jan 13, 2010)

Saturated fat found mainly in animal products has been vilified by physicians, the media, and the edible oil industry for over 60 years, despite mounds of evidence to the contrary. A meta-analysis of 21 prospective epidemiologic studies that had a total of 347,747 participants, showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of cardiovascular disease or stroke.

Saturated fats have been nourishing societies around the world for thousands of years. If animal fats (saturated fats) are so dangerous, and vegetable oils (polyunsaturated fat) are so healthy, why are we so unhealthy as a nation? The scientific data of the past and present does not support the assertion that saturated fats cause heart disease. As a matter of fact, people who have had a heart attack haven?t eaten any more saturated fat than other people, and the degree of atherosclerosis at autopsy is unrelated to diet.Ravnskov, Uffe. ?The cholesterol Myths: Myth number 4?
