Fish oil from algae protects cardiovascular system too
Maybe you don't like the idea of animals dying for you to feed yourself, or perhaps you'd prefer not to contribute to completely decimating the planet's fish population? Then you probably don't want to take supplements containing fish oil either, even though they have very interesting health effects. Fortunately there's an alternative.
Our cardiovascular system & DHA
The problem is that there aren't enough fish on the planet to provide us all with enough omega-3 fatty acids. [Curr Opin Clin Nutr Metab Care. 2015 Mar;18(2):147-54.] What's more, the number of people who prefer to eat foods that have not involved animals dying is on the increase.
The Harvardians confined themselves to studies on the effect of algae-derived DHA on the concentration of triglycerides in the blood. One of the reasons that fish oil protects blood vessels is that fish fatty acids keep the concentration of glycerides low. The lower the concentration of triglycerides, the lower the chance of atherosclerosis and, in the long term, heart attacks and strokes.
All doses between 0.7 and 2.8 g algae-DHA had the same effect. So it's not necessary to take more than 0.7 g algae-derived DHA.
Algae-DHA supplementation had no clear net effect on cholesterol balance. HDL levels rose by a few percent, as did those of LDL.
