Most people believe that high fat meals are not healthy. What is not that well known are the immediate effects of a high fat meal on the function of blood vessels. The study reviewed is very interesting because it investigated the acute impairments of a high fat meal on endothelial function (Fahs CA, et al. 2010). The endothelium is the inner lining of the blood vessels. The researchers measured several factors related to the endothelial function and arterial stiffness at rest and also 4 hours after a high fat meal supplemented either with a placebo or 1 gram of EPA and DHA, which are the active ingredients of omega 3 fish oil.
After the high fat meal supplemented with the placebo, the brachial artery flow-mediated dilation normalized for shear rate, was significantly impaired, but it remained unchanged when the high fat meal was supplemented with the fish oil. Impaired flow-mediated dilation has been demonstrated many years before the appearance of plague and is a way to detect dysfunctional changes in blood vessels. Omega 3 fish oil does not only provide a variety of long term benefits, but it also provides an immediate benefit. To read more about the benefits of omega 3 fish oil, click here.
