Meat products contain both saturated and unsaturated fats. Although unsaturated fats are conventionally regarded as 'healthier' than saturated fats, [6] the United States Food and Drug Administration (FDA) recommendation stated that the amount of unsaturated fat consumed should not exceed 30% of one's daily caloric intake. [7] Most foods ...

The evening primrose flower (O. biennis) produces an oil containing a high content of γ-linolenic acid, a type of omega−6 fatty acid.Omega−6 fatty acids (also referred to as ω−6 fatty acids or n−6 fatty acids) are a family of polyunsaturated fatty acids (PUFA) that share a final carbon-carbon double bond in the n−6 position, that is, the sixth bond, counting from the methyl end.
Part of the confusion may stem from the fact that these polyunsaturated fats are found in a wide range of foods, from healthy nuts and eggs to highly processed foods like chips and french fries ...
Thus, for example, the 20-carbon arachidonic acid is Δ 5,8,11,14, meaning that it has double bonds between carbons 5 and 6, 8 and 9, 11 and 12, and 14 and 15. In the context of human diet and fat metabolism, unsaturated fatty acids are often classified by the position of the double bond closest between to the ω carbon (only), even in the case ...
16- and 18-carbon omega−7 unsaturated fatty acids are known to be converted into 18- or 20-carbon highly unsaturated fatty acids in the body by nonselective desaturating enzymes. [4] The same enzymes also act on omega−3, omega−6, and omega−9 fatty acids. As a result, while proportions of individual highly unsaturated fatty acids may ...
Some omega−9 fatty acids are common components of animal fat and vegetable oil. Two omega−9 fatty acids important in industry are: Oleic acid (18:1, n−9), which is a main component of olive oil, macadamia oil and other monounsaturated fats; Erucic acid (22:1, n−9), which is found in rapeseed, wallflower seed, and mustard seed.
When cattle are taken off omega−3 fatty acid-rich grass and shipped to a feedlot to be fattened on omega−3 fatty acid deficient grain, they begin losing their store of this beneficial fat. Each day that an animal spends in the feedlot, the amount of omega−3 fatty acids in its meat is diminished. [103]
