Smart Girls Eat Fish

Girls who eat more omega-3 fatty acids outsmart those who eat higher amounts of omega-6 fatty acids, according to new research. As a result of this and other studies, government dietary recommendations--especially those aimed at pregnant women--should emphasize fish over soy and corn oils, which are respectively high in these fatty acids.

Women who accumulated more fat on their hips than on their waists--and who, therefore, had low waist-hip ratios like many movie stars--had higher cognitive test scores, as did their children

The study of middle-aged adults in China, Japan, Great Britain and the U.S. found that people who ate more foods rich in omega-3 fatty acids tended to have lower blood pressure. This relationship was seen with fish, as well as with vegetable sources, such as canola oil, soybean oil, flaxseeds and walnuts, according to lead author Dr. Hirotsugu Ueshima of Shiga University, Japan, and associates.The findings, published online in the journal Hypertension, add to evidence of the heart benefits of omega-3 fatty acids.

Recruitment of Compensatory Pathways to Sustain Oxidative Flux With Reduced Carnitine Palmitoyltransferase I Activity Characterizes Inefficiency in Energy Metabolism in Hypertrophied Hearts

"Transport rates of long-chain free fatty acids into mitochondria via carnitine palmitoyltransferase I relative to overall oxidative rates in hypertrophied hearts remain poorly understood. Furthermore, the extent of glucose oxidation, despite increased glycolysis in hypertrophy, remains controversial. The present study explores potential compensatory mechanisms to sustain tricarboxylic acid cycle flux that resolve the apparent discrepancy of reduced fatty acid oxidation without increased glucose oxidation through pyruvate dehydrogenase complex in the energy-poor, hypertrophied heart."
