Here is something you can sneak into your meals and boost your health without even noticing. Flaxseed is another one that’s similar to cod liver oil, as it contains a lot of omega-3 fatty acids. The flaxseeds are pretty easy to find, and you can have them as whole seeds in smoothies or grind them up. You can ground them into a powder, and many people also like to cook with this as an alternative to natural grains. It also helps with inflammation. Flaxseed doesn’t thin out your blood as much either, and it is excellent for many people who enjoy adding these to smoothies.
