Coronary Heart Disease

Read on for detailed information about how various oils contribute to your heart's health.

Evening Primrose Oil
There is evidence of an association between the risk of coronary heart disease (CHD) and the essential fatty acids (EFAs) contained in EPO with decreased plasma levels of the GLA metabolites, arachidonic acid (AA) and dihomo-gamma-linolenic acid (DGLA), considered to be independent risk factors for CHD(1). In an epidemiological study of CHD incidence and adipose (fat tissue) EFA levels, men living in areas of very high CHD incidence were found to have significantly lower levels of DGLA, AA and linoleic acid (LA) than men living in areas of lower CHD incidence (2). Furthermore, a prospective observational study of middle-aged men reported that levels of LA and DGLA were significantly reduced in patients being diagnosed with CHD for the first time (3).

Borage Oil
An epidemiological study of GLA levels as a factor in coronary heart disease (CHD) reported that men living in areas of very high CHD incidence were found to have significantly lower levels of dihomo-gamma-linolenic acid (DGLA) and arachidonic acid (AA) (metabolites of GLA) than men living in areas of lower CHD incidence (4). Furthermore, a prospective observational study of middle-aged men reported that levels of DGLA and linoleic acid (LA) were significantly reduced in patients being diagnosed with CHD for the first time (5).
