Alpha-linolenic acid and coronary heart disease.

M de Lorgeril et al.

Nutrition, metabolism, and cardiovascular diseases : NMCD, 14(3), 162-169 (2004-08-28)

To summarize our present knowledge about vegetable omega-3 fatty acids. Alpha-linolenic acid (ALA) is one of the two essential fatty acids in humans. Epidemiological studies and dietary trials strongly suggest that this fatty acid is important in relation with the

n-3 Fatty acids from fish or fish-oil supplements, but not alpha-linolenic acid, benefit cardiovascular disease outcomes in primary- and secondary-prevention studies: a systematic review.

Chenchen Wang et al.

The American journal of clinical nutrition, 84(1), 5-17 (2006-07-11)

Studies on the relation between dietary n-3 fatty acids (FAs) and cardiovascular disease vary in quality, and the results are inconsistent. A systematic review of the literature on the effects of n-3 FAs (consumed as fish or fish oils rich
