The Skinny on Saturated Fats

Maybe Gary Taubes already said this, but sat fats are not the culprit.

I'm reading an article by J Bruce German and Cora J Dillard, from the American Journal of Clinical Nutrition, 2004;80:550-9, for those who check references.

What the article basically says, is don't throw the baby out with the bathwater. First, what more and more of us know, "high-carbohydrate diets were recognized as contributing to the lipoprotein pattern that charcterizes atherogenic dyslipidemia and hypertriacylglycerolemia."

In short, when the food industry began to remove sat fats from foods, they substituted carbohydrates in many forms. And those carbs not only made us fatter or obese, they changed our blood lipid profile to one which is "atherogenic" or bad for our blood vessels and circulation, and they gave us high triglycerides. Thanks a lot.

More interestingly, the article points out some of the things that saturated fats, or fatty acids, do is not bad, and what's more, some have positive effects on the body. The article states that there is no strong evidence that saturated fat elevates LDL cholesterol and thus the risk of CAD. What has not been studied is the possibility that some of the saturated fats might have positive effects, since mammals have within the mammary gland the means to produce a number of saturated fats, namely butyric, caproic, caprylic, capric, lauric, myristic, palmitic and stearic acids, to ensure the growth and survival of mammalian offspring. Evolution is a funny things, and things seem to have happened for a reason.

The article notes that saturated fats are the preferred fuel for the heart, a source of fuel during energy expenditure.

It concludes that the advice to remove sat fats from the diet has made us all fatter, and has failed to have any effect on the prevalence of diabetes and cardiovascular disease.

Next time: the sat fats and what they do for us.

Low Carb diets do work folks.

So my husband and I have been following a sort of South Beach diet, somewhere between strict phase 1 and phase 2. He of course has lost 10 lbs to my 7, which is par for the course. I don't eat fish which complicates things. I'd like to but get a scratchy throat which could mean allergies. But we've eaten chicken, beef, ribs etc, cottage cheese, cheese.....just little bread. It can be done. I've been eating carb free jello. I have sugar free coffees.

Most interesting is that my blood sugar (I'm a type2 diabetic) is now hovering between 5 and 7 all the time. My doc reduced my metformin a bit. Nice!!! My ankles aren't swollen as much, and she also reduced one of my heart meds that affect my blood pressure. I went to Pritikin in the spring and they say that losing 5% of your body weight improves your health, so I am closing in on that. I need to do it several times.

I got onto this because one of my acquaintances lost 60 lbs and improved her blood profile while doing it. She pointed me to the book "Good Calories, Bad Calories" by Gary Taubes and the rest is history, in that I am doing lots of research on the idea that carbs and therefore insulin can almost be said to be the root of most of the obesity epidemic.

Of course skinny folks don't have to worry as much except if they eat a high carb diet, of simple and easily digestable carbs. Also high fructose corn syrup is a culprit. But being fat brings its own brand of wonderfulness - high blood sugar, high insulin readings, insulin resistance. Fat doesn't just lie there, it is working all the time and affecting you.

I'll let you know how things go, and how my blood profile changes over the next while. Learning to burn fat and stay away from carbs will be interesting.
