For most adults, dietary fat should provide at least 15% of total energy and 20% for women of reproductive age. Fat is also an important source of vitamins A, D, E and K.
Unsaturated fat, also known as the ‘good’ fat, is important for heart health, as as it helps reduce total cholesterol in the blood.
Saturated fat, or the ‘bad’ fat, is not so good, because it increases total cholesterol.
Having a balance of mono- and poly-unsaturated fat is important. Mono-unsaturated fat is a 'good' fat found in lean red meat and some oils, poly-unsaturated fat is a 'good' fat found in fish, seeds and some oils
A type of 'good' fat which can help lower blood level of LDL ('bad') cholesterol

For pregnant women, eating the enough of the unsaturated fat is vital for energy, as well as fetal growth. Omega 3 and Omega 6 fatty acids are two types of poly-unsaturated fat which are very important. The fetus has a limited ability to make these fats, so it is dependent of placental supply.
After child birth, many women tend to focus on losing weight. However those who are breast feeding have even higher energy requirements than during pregnancy.
