In biochemistry and nutrition, a polyunsaturated fat is a fat that contains a polyunsaturated fatty acid (abbreviated PUFA), which is a subclass of fatty acid characterized by a backbone with two or more carbon–carbon double bonds. [1] [2] Some polyunsaturated fatty acids are essentials.
The Dietary Goals also recommended increasing complex carbohydrates and naturally occurring sugars from 28% to 48% of energy intake, reducing refined and processed sugars to about 10% of energy intake, reducing fat from 40% to 30% of energy intake, reducing eating saturated fat to 10% of energy intake, reducing cholesterol consumption to 300 ...

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.
The U.S. Food and Drug Administration (FDA) announced a new definition of “healthy” food for the first time in 30 years. The new definition will apply to manufacturers who want to call their ...
This is because all fats contain some saturated fatty acids. For example, if a person chose fats with only 20% saturated fatty acids, setting fat intake at 35% of total calories would mean that 7% of calories would come from saturated fat. For this reason, the Institute of Medicine recommends consuming no more than 35% of calories from fat. [3]
Amounts of fat types in selected foods. Although polyunsaturated fats are protective against cardiac arrhythmias, a study of post-menopausal women with a relatively low fat intake showed that polyunsaturated fat is positively associated with progression of coronary atherosclerosis, whereas monounsaturated fat is not.
