Omega-3 fatty acids are considered essential fatty acids. They are essential to human health but body cannot make its own omega-3 fats, they must be taken in through the diet, or in supplement form. For this reason, omega-3 fatty acids must be obtained from food.
The fats are naturally found in oily cold water fish like tuna, salmon, and sardines. Vegetable sources include pumpkin seeds, flax seeds, and walnuts. Getting omega-3 fatty acids from food rather than from capsule supplements ( Omega3 fish oil )can be more beneficial, providing additional nutrients.
There are two great fish sources for Omega-3 fatty acids many of us aren’t familiar with.
Sardines are rich in Omega-3s, and so is herring.
