Saturated, Monounsaturated, and Polyunsaturated Fatty Acids
Fatty acids are the predominant compounds in all fats. However, depending on their source (olive, sunflower, peanut…), the nature of fatty acids varies from one oil to another.
Saturated Fatty Acids
They play an important role as an energy provider, but excessive consumption increases overall blood cholesterol levels, which can contribute to increasing the risk of cardiovascular diseases.
Polyunsaturated Fatty Acids
They are essential and indispensable because the body cannot do without them and cannot produce them.
Monounsaturated Fatty Acids
They are either neutral and generally have no effect on blood cholesterol levels, or they induce a decrease in total cholesterol and LDL-cholesterol (“bad cholesterol”) but not HDL-cholesterol (“good cholesterol,” which would tend to increase). As such, it is particularly beneficial to consume them as a substitute for saturated fatty acids.
Good to know
According to nutritional recommendations, 30 to 35% of the energy provided by food should come from lipids.
To meet these recommendations, an adult should consume an average of 65 to 80 g of lipids daily through all possible sources of lipids in their diet (intrinsic fats in foods, oils and butter added to foods…).
