Researchers may have identified a way to lower blood cholesterol, according to the results of a study reported in the Journal of the American Dietetic Association (July 2005). They found that a diet rich in NuSuna new type of sunflower oilbeat olive oil when it came to reducing levels of low-density lipoprotein (LDL; "bad") cholesterol in 31 participants. The sunflower oil had a relatively high concentration of both polyunsaturated fatty acids and monounsaturated fats.
For the study, the participants followed each of three 4-week diets: one heavy in foods with sunflower oil, another rich in olive oil, and one typical of the "American" diet. The oil-based diets had equal amounts of saturated fat, but the sunflower diet had a greater balance between mono-and polyunsaturated fats. The American diet contained more saturated and total fat, compared with the other 2 diets.
The results of the study showed a 6% drop in LDL levels among participants following the sunflower-oil diet, compared with their time on the American diet. The diet rich in olive oil demonstrated no major effect on LDL levels, however. "Within the context of a moderate-fat diet, it is becoming clear that a mixture of unsaturated fatty acids provides the greatest health benefits," wrote the investigators.
One study linked multiple pregnancies to an increased risk of developing atrial fibrillation later in life, and another investigated the association between premature delivery and cardiovascular disease.
