Preliminary studies have shown that flaxseed powder, rich in the omega-3 alpha-linolenic acid,is beneficial for the general inflammation present in morbidly obese subjects by decreasing elevated serum markers.As omega-3 fatty acids display additional properties including possible amelioration of atherosclerosis,a 3-month supplementation protocol was devised.Arterial stiffness and intima thickness will be measured in severely obese subjects, in order to document possible reduction of these variables as well.
