Body weight and low-density lipoprotein cholesterol changes after consumption of a low-fat ad libitum diet

Article Abstract:

A low-fat, reduced calorie diet can effectively lower blood levels of total cholesterol (TC) and low-density-lipoprotein cholesterol (LDL-C) without adversely affecting blood levels of high-density-lipoprotein cholesterol (HDL-C). High levels of TC and LDL-C are linked to an increased risk of coronary artery disease, while high levels of HDL-C are thought to reduce the risk. Researchers studied 27 men and women with hypercholesterolemia who followed three different diets over a period of time: a typical American diet, a low-fat, controlled calorie diet and a low-fat diet where they could eat as much as they wanted (ad libitum). The low-fat controlled calorie diet lowered TC and LDL-C but also HDL-C. The low-fat ad libitum diet lowered TC and LDL-C to a much greater extent than HDL-C. Most of the participants ate less on the ad libitum diet and many lost weight.

Effects of different forms of dietary hydrogenated fats on serum lipoprotein cholesterol levels

Article Abstract:

Margarine that is low in trans fatty acids can lower blood cholesterol levels. Researchers measured blood levels of total cholesterol, LDL (`bad') cholesterol, and HDL (`good') cholesterol in 18 women and 18 men who consumed a variety of fat products, including butter, stick margarine, soft margarine, semiliquid margarine and soybean oil. Butter and stick margarine have higher levels of trans fatty acids compared to the other products. Soybean oil lowered LDL cholesterol levels the most, followed by semiliquid margarine, soft margarine, and stick margarine in that order.

Elevated plasma lipoprotein(a) and coronary heart disease in men aged 55 years and younger: a prospective study

Article Abstract:

Elevated plasma lipoprotein(a) may be an additional risk factor for coronary heart disease in middle-aged men. This was demonstrated in the Framingham Offspring study, which has followed the children of the original Framingham population since 1971. At the fourth examination between 1987 and 1991, men whose lipoprotein(a) was elevated in the early 1970s were twice as likely to develop coronary heart disease. The risk was as strong as the risk of elevated cholesterol. However, smoking was the strongest risk factor for coronary heart disease in these men.
