When reducing dietary fat intake, it is recommended that the majority of dietary lipids come from monounsaturated fats. Monounsaturated fats are beneficial because they can help reduce bad cholesterol levels (LDL) while increasing good cholesterol levels (HDL), promoting overall heart health. These fats are found in foods like olive oil, avocados, and nuts.

In contrast, polyunsaturated fats, while also healthier than saturated and trans fats, should not dominate dietary fat sources in the way monounsaturated fats can. They can contribute to heart health but are not as widely recommended for the bulk of fat intake compared to monounsaturated options.

Saturated fats are generally advised to be limited in the diet because excessive consumption can raise LDL cholesterol levels, presenting a higher risk for heart disease. Trans fats are considered the least healthy option, as they are linked to increased risk of heart disease and should be avoided as much as possible.

Thus, monounsaturated fats represent a healthier choice for the majority of dietary fats due to their positive effects on cardiovascular health and cholesterol levels.
