Fat is a source of energy found in foods. It provides around 9 calories per g, more than twice the number provided by protein or carbohydrates.
According to WHO, the daily intake of fat should not exceed more than 1/3 of their total energy needs.
Basically, there are three main types of fats: saturated, unsaturated and trans fats.
Saturated Fats are found in animal products like butter, cheese, lard and fatty meats, and some vegetable oils such as coconut and palm oil.
Saturated fats can increase the cholesterol level, which will increase the risk of heart disease. Obesity, another risk factor for heart disease, is likely to occur because of the high calorie content.
