Lower chance of stroke among women who eat oily fish

Sunday, July 10th, 2011

Eating fish helps reduce the chance of heart disease and mortality, but its contribution to stroke prevention has been debatable.

There are good reasons to suspect that fish consumption might moderate the likelihood of a stroke. That is because the omega-3 fatty acids (omega-3s) in fish improve the function and tone of blood vessels, have a modest blood-pressure-lowering effect and lower the tendency for blood clots to form. In this new report, investigators calculated the chance of developing a stroke in nearly 35,000 middle-aged to elderly women living in Sweden who were monitored for 10 years.

Fish consumption is common in Sweden and on average the women in this study ate fish twice a week. The investigators observed that the chance of developing a stroke decreased with higher fish consumption. Overall, women who ate fish twice or more per week were 16% less likely to develop a stroke compared with women who ate fish less than weekly. Women who ate 4 or more meals of fish per week had an even lower chance (28%) of a stroke. In this population, there was no difference according to the type of fish consumed, fatty or lean. That unexpected observation might have been because people in Sweden frequently eat fatty fish in salted form. High intakes of sodium (from salt) increase the chance of high blood pressure and stroke. For those who dont like oily fish the easiest way to get a daily dose of omega3 is to take a high grade supplement such as TakeOmega3 which offers the highest concentrations of EPA currently available .

It should be noted that these observations pertained to ischemic stroke, the kind resulting from impaired blood flow to the brain. This is by far the most common type of stroke in the U.S. and many Western countries. Women who ate fish regularly were also more likely to eat more fruit and vegetables and consume alcohol compared with women who ate fish infrequently.

Omega 3 EPA reduces LDL cholesterol levels – TakeOmega3 has 750mg EPA per capsule

Wednesday, December 15th, 2010

New clinical study results presented at the American Heart Association Scientific Sessions show that the long-chain omega-3 fatty acid EPA (eicosapentaenoic acid), helped significantly reduce small dense LDL (bad) cholesterol levels.

“This study suggests that supplementation with the omega-3 fatty acid EPA may present unique benefits for cardiovascular health,” said Sujata K. Bhatia, M.D., Ph.D., research associate with DuPont. “EPA was shown to have advantageous effects on several biomarkers, including LDL cholesterol, small dense LDL, and lp-PLA2.”

EPA is a long-chain fatty acid that is found primarily in cold water, fatty fish like sardines anchovies mackerel  as well as some omega-3 fatty acid such as TakeOmega3 which has 750 mg EPA per capsule  and is the highest grade omega 3 available in UK . A growing body of evidence suggests that EPA is the long-chain omega-3 that supports heart health.

The study, conducted by Cardiovascular Research Associates and sponsored by DuPont, was conducted among 110 healthy individuals comparing the effects of EPA supplements to DHA (docosahexaenoic acid) supplements on cardiovascular health. The participants were placed into four study groups and examined over a six week period. During that time, each group was monitored while taking: EPA 600 mg per day; EPA 1,800 mg per day; DHA 600 mg per day; and an olive oil placebo.

The study found that in the 1,800mg EPA group, there were significant reductions of 7 percent for small dense low density lipoprotein (LDL) cholesterol, and 6 percent for lipoprotein-associated phospholipase A2 (lp-PLA2). lp-PLA2 is an enzyme involved in vascular inflammation.
In contrast, the 600mg DHA group showed a significant increase in total small dense LDL cholesterol in both the fasting and fed state of 14.2 percent and 16.3 percent respectively.

The study results will be featured during the American Heart Association Conference poster session in Chicago
