Could Omega-3s Boost Blood Fat Levels?: MedlinePlus - 0 views

  •  
    "THURSDAY, Dec. 17 (HealthDay News) -- In a surprise finding, Canadian researchers report that the immediate effect of the fish oil fatty acids that are good for the heart is a short-term increase in blood fats and the molecules that help them form clots.

    "We were surprised to find that the acute response has some potentially negative effects in comparison to what you might expect from chronic, long-term intake," said Lindsay E. Robinson, an associate professor of nutrition at the University of Guelph, and leader of the group reporting the finding in the January issue of the Journal of Nutrition.

    However, the study results shouldn't affect the current recommendation for eating more oily fish to get the omega-3 polyunsaturated acids that reduce the risk of blood clots that can cause heart attacks and stroke, Robinson said.

    "The recommendation to increase intake is very well-studied, and this doesn't change it," she said.

    And the effects were seen in a selected group of middle-aged men with metabolic syndrome, a combination of high blood pressure, obesity and elevated blood fat levels, Robinson noted.

    In the study, eight men had controlled intake of three regimens: high doses of omega-3 fatty acids, low doses of them and just plain water. Robinson and her colleagues measured several blood components involved in clotting, including fats and clotting factors such as plasminogen-activator inhibitor-1 (PAI-1) for the following eight hours.

    PAI-1 inhibits the destruction of blood clots, so high levels of it in the blood increase the risk of artery-blocking clots.

    The researchers found that both omega-3 fatty acid regimens increased blood fat and clotting factor activity. But the increase in clotting factor was greater for the higher doses of omega-3 fatty acids than for the lower intakes.

    Robinson said her group hopes to do further studies of the immediate effects of omega-3 fatty acid intake. "We need to look at the mechanisms, why blood lipid levels go up," she

  •  
    The results suggest that a short-term ketogenic diet does not have a deleterious effect on CVD risk profile and may improve the lipid disorders characteristic of atherogenic dyslipidemia.

    A ketogenic diet favorably affects serum biomarkers for cardiovascular disease in normal-weight men.
