A good source of omega 3

Omega-3 is short for omega-3 polyunsaturated fatty acids. They are a family of “essential fats” that play an important role in the way our cell membranes work. Oily fish is one of the best known sources and eggs contain similar types of omega-3s as those found in fish. This makes eggs particularly useful for people who avoid or can’t eat fish. Omega-3 fats are good for many things, from heart and brain health to protecting our eyes.
