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.

Oleic acid has 18 carbons, is found in most animal fats and olive oil, and is a cis-9-monounsaturated fatty acid. C 17 H 33 CO 2 H, IUPAC organization name (Z)-octadec-9-enoic acid, numerical representation 18:1 (9), n-9, molecular weight 282.46, melting point 13.4 °C, specific gravity 0.891. CAS Registry Number 112-80-1.
For example, a recent large meta-analysis found that replacing some saturated fats with polyunsaturated fats (like seed oils) was associated with a lower risk of cardiovascular disease and type 2 ...
Dairy products are one of the primary sources of dietary omega−7 fatty acids. However, the production of omega−7 fatty acids in cows is heavily diet-dependent. [7] Specifically, a reduction in the proportion of herbage consumed by a cow is correlated with a significant decrease in the omega−7 fatty acid content of the cow's milk. Rumenic ...
Best foods for heart health contain fiber, healthy fat, antioxidants and fight inflammation. Add these 16 foods to your diet to prevent heart disease.
It helps to imagine food as a spectrum: At one end, you have nutrient-dense, anti-inflammatory foods (think: colorful vegetables, berries, high-quality olive oil, fatty fish, nuts, seeds, and ...
