It is important to keep a check on consumption of cooking oil in order to keep a check on your cholesterol levels. Nutritionists and dietitians recommend that it is important to include all kinds of cooking oil in your diet. This is because different oils have different fatty acids and all fatty acids are important for the body. From coconut oil to rice bran oil, soya bean oil, mustard oil and olive oil, it is important to include all varieties of oil in diet to get all essential fatty acids. When it comes to cooking oils, it is important to consider their stability and prevent their oxidation. When oils undergo oxidation, they form free radicals and harmful compounds by reacting with oxygen. These free radicals are extremely harmful for the body. The resistance of oil to oxidation and rancidification can be checked by degree of saturation of fatty acids in it.

While saturated fats have single bond in fatty acid molecules, monounsaturated fats have double bond and polyunsaturated fats have 2 or more bonds with fatty acid molecule.
Of these bonds, it is the double bonds which are chemically more reactive and are more sensitive to heat. Oils that are high in polyunsaturated fats should be avoided. Saturated and monounstaturated fats are resistant to heating.
We ask Delhi-based nutritionist Pooja Malhotra about how much cooking oil is safe to consume in a day, and she says that 4 tsp of visible fat (added fat) is safe to be consumed in a day. The amount of cooking oil which we use should not exceed 4 tsp in a day. This, she says, is because of the fact that there is a lot of invisible fat in many food items like dairy, egg, nuts, seeds, chicken, seafood, meats etc.

Things to keep in mind
To ensure that your fats don't go rancid, avoid buying them in bulk. This way, you will probably consume them before they begin to deteriorate in their quality. Heat, light and oxygen are the main drivers which cause oxidation of cooking oils. Keep them in a cool and dry place to prevent them from going rancid or getting oxidised. Also make sure that your close the lid as soon as you use them.
