In the beginning, people ate meat. The fat came with the meat. The best parts were the fattiest, bone marrow, etc. That where the saturated fats come from. That's what we were meant to eat. Omega 3 is another fat that we are biologically suited for. Omega 3 is the most common fat in the world. It's in grass, algae and most other plants at the bottom of the food chain. It accumulated in animals that eat those green plants. It's not in seeds with minor exceptions. Seed oil is a processed food that is low in both saturated fat an omega 3. Some plants have oil in their flesh like olives, coconuts, nuts and avocados. These don't have to be processed to extract oil, you just press it.
It all comes back to "eat real food". Seed oils of any type, are not real foods.
So I have another question on this subject...nut oils like peanut, walnut, almond, cashew, etc are ok then? I like olive and avocado, but I despise coconut oil. Tastes too much like coconut, which I hate. I also do not really like butter either (I know its weird, just not a big fan). But I like to top certain foods with like tuna with oils and just wondering what to use. Oh and what about flax seed oils then? Heard good things about it...
