Lipids at room temperature that are solid are called fats while those that are liquid are called oils.

Oils and fats have Saturated, Mono Unsaturated (MUFA), Poly Unsaturated (PUFA) and essential fatty acids (EFA).

Food items such as sunflower oil, gingley oil, soybean oil, fish etc. containing Poly Unsaturated (PUFA) should be preferred, yet consumed in moderation.

Substitute unsaturated fat - either Poly Unsaturated (PUFA) or Mono Unsaturated (MUFA). Keep your fat calories to about 15-20% of your total calories.

People having heart diseases or high blood pressure should use oils and fats that are high in Poly Unsaturated (PUFA).
