Why olive oil? / A practical guide
Olive oil and monounsaturated fats
Olive oil is rich in monounsaturated fat, particularly oleic acid, and can form part of balanced eating when it replaces fats higher in saturated fat.
Fats are not all the same. Monounsaturated fats are unsaturated fats, and olive oil is one familiar food source.
WHO guidance favours unsaturated fats over saturated and trans fats. The practical idea is substitution: use olive oil in place of some butter or other fats higher in saturated fat where it suits the food.
Context still matters. Olive oil belongs naturally with vegetables, legumes and other whole foods rather than being treated as a supplement to add indiscriminately.
