Omega-3 fats also lower blood pressure and heart rate, improve blood vessel function, and, at higher doses, lower triglycerides and may ease inflammation, which plays a role in the development of atherosclerosis. Several large trials have evaluated the effect of fish or fish oils on heart disease.
They identify key genes and signaling pathways controlled by vitamin D3 and omega-3 DHA, that may help the immune system regulate inflammation and get rid of plaque. For their study, Fiala and colleagues isolated immune cells from blood samples taken from Alzheimer's patients and healthy volunteers for comparison.
