[An eicosapentaenoic acid-rich diet in relation to a reducing diet and physical training]

The effect of a mackerel diet alone or in connection with reducing diet and physical training has been tested during 4 weeks in 49 male patients with cardiovascular diseases undergoing a cure and in 45 males with healthy metabolism. 1st group: 15 persons with healthy metabolism, 240 g/die supplementary mackerel diet, no physical training; 2nd group: 16 cure patients with reducing diet (5,000 kJ/d), no mackerel diet, no physical training; 3rd group: 14 cure patients with reducing diet and a proportion of mackerels of 125 g/d, no physical training; 4th group: 19 cure patients with reducing diet and mackerel diet 125 g/d as well as daily swimming training (20 to 30 min). The decrease of beta-C and Apo B was most distinct in groups 3 and 4 and lay between 21 and 35%. The combination reducing diet with proportion of mackerels proved to be most effectively for the decrease of the atherogenic LDL and was superior to the monotherapies. A significant increase of the HDL (measured in alpha-C and Apo A) took place only in group 4 with simultaneous performance of physical training, alpha-C increased by 31 and Apo A by 8%.
