Eating fatty fish increases the size and lipid composition of HDL particles in people with impaired glucose metabolism, according to a new study from the University of Eastern Finland. These changes in the size and lipid composition of HDL particles make them beneficial for cardiovascular health. Published in Molecular Nutrition & Food Research, the study also found that camelina sativa oil decreases the number of harmful IDL particles.

The researchers studied the effects of camelina oil and fatty fish intake on the size and composition of cholesterol-carrying lipoproteins. The HDL lipoprotein is commonly known as "the good" cholesterol, although the health effects of HDL particles actually are dependent on their size and composition. Earlier research has shown that large HDL particles are associated with a reduced risk of cardiovascular diseases, whereas a small HDL particle size may…
