Because of their effects in the diet, unsaturated fats (monounsaturated and polyunsaturated) are often referred to as good fats; while saturated fats are sometimes referred to as bad fats. Some fat is needed in the diet, but it is usually considered that fats should not be consumed excessively, unsaturated fats should be preferred, and ...
Increasing monounsaturated fat and decreasing saturated fat intake could improve insulin sensitivity, but only when the overall fat intake of the diet was low. [7] However, some monounsaturated fatty acids (in the same way as saturated fats) may promote insulin resistance , whereas polyunsaturated fatty acids may be protective against insulin ...
Monounsaturated fats are found in animal flesh such as red meat, whole milk products, nuts, and high fat fruits such as olives and avocados. Olive oil is about 75% monounsaturated fat. [119] The high oleic variety sunflower oil contains at least 70% monounsaturated fat. [120] Canola oil and cashews are both about 58% monounsaturated fat. [121]
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 ...
An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond.
However polyunsaturation of cell membranes may also occur in response to chronic cold temperatures as well. In fish increasingly cold environments lead to increasingly high cell membrane content of both monounsaturated and polyunsaturated fatty acids, to maintain greater membrane fluidity (and functionality) at the lower temperatures.

Swapping saturated animal fats such as butter with plant-based unsaturated fats such as olive oil may help reduce the risk of developing cardiovascular disease and type 2 diabetes, a new study ...
