EFA's are healthy fats. EFA refers to Omega 3, 6 and 9 fatty acids.
Fish oil is loaded with Omega 3, and that kind is the hardest to get in your diet. Nuts have some omega 3, but are much higher in 6 and 9.
The average person needs less saturated fat, and usually are fine on 6 and 9...but lack 3. Eating salmon and taking fish oil caps (about 8-10 per day for average person) is a good way to supplement enough into your diet.
Take 2 caps per meal, except post workout...that's 10 caps a day there. easy to do if you just take them.
