Monounsaturated fatty acids (n-9) can be synthesised by the body and are not considered essential fatty acids, hence there is no adequate or recommended intake limit set. ^[1]

Plant sources rich in monounsaturated fatty acids are liquid at room temperature. ^[3]

Of the known types in this category, oleic acid accounts for about 92 % of dietary monounsaturated fatty acids. ^[3]

Replacing calories from carbohydrates with equivalent calories from monounsaturated fats can reduce mortality risk by 19%. ^[5]

Absorption of mono-unsaturated fatty acids is in excess of 90% in adults and infants. ^[2]

Since oleic acid is completely absorbed, very little is actually excreted through urine. ^[2]
