Q: Hi Mike, what would be the best foods to eat to get the daily fat intake i need, in a weight gaining diet

A: Extra virgin olive oil (for use in salads, not in cooking!), fatty fish, ground flax seed (or flax oil, though I definitely prefer plain ground flax seed), as well as nuts and egg yolks. Most of your fat intake should be monounsaturated fats which are plentiful in extra virgin olive oil.

Besides monounsaturated fats, try to get at least some omega-3 polyunsaturated fats in your diet. These can be found in fatty fish such as salmon and flax seed. Do NOT go out of your way to get enough omega-6 polyunsaturated, however -- although it is an essential fatty acid like omega-3, it is present in many foods, especially things like commercial salad dressings (which you should avoid) and soy/nuts/peanut butter and most people get too much of it already.

If you eat meat or chicken you will get a lot of fats from them as well, mostly in saturated and monounsaturated form. That's fine, just try to get as lean meats and poultry as possible. That means skinless poultry and 90% lean or better beef.
