Your body needs essential fatty acids to function, but cannot manufacture them on its own. Two important essential fatty acids are omega-6, also known as linoleic acid, and omega-3, or alpha-linolenic acid. Safflower oil contains 10.15 g of omega-6 per tablespoon, while canola oil has 2.68 g of omega-6 and 1.28 gr of omega-3 per tablespoon. Both omega-6 and omega-3 fatty acids boost immune function and increase vascular health. Other sources of omega-6 include soybeans and sunflower seeds, while many fish and nuts contain omega-6. You need both essential fatty acids in your diet, so consuming more vegetable oils such as safflower and canola can help you get them.
