In the American diet vegetable oil is the one source of fat. These days there is increasing concern of which omegas are healthy and in what ratio.
So many Omegas: Which ones are good? Omega-3 or Omega-6:
Omega-6 fats fall under the “bad fats” category and are pro-inflammatory, and there is evidence that higher consumption of these fats is related to brain disorders. American diet is extremely high in omega-6 fats which are found in many vegetable oils, including safflower oil, corn oil, canola oil, sunflower oil and soybean oil.
Our hunter-gatherer ancestors consumed omega-6 and omega-3 fats in a ratio of roughly 1:1. Today we consumed ten to twenty-five times more omega-6 fats and have dramatically reduced our intake of healthy omega-3 fats.
The following chart lists the omega-6 and omega-3 content of various vegetables oils.
|Oil||Omega-6 Content||Omega-3 Content|
So seafood is great source of omega-3 fatty acids and even wild meats- beef, venison and buffalo. But if animals are fed grains (corn and soybeans) then they will not have adequate omega-3 in their meat. Hence it’s better to consume grass-fed beef and meats to get all the vital nutrients in our diet.
