When ghee is used prudently, it has multiple advantages over margarine and butter – the obvious one – a long shelf life – it does not turn rancid.

Ups:
• For people who are allergic to lactose and cannot tolerate butter – ghee is a good choice as all the milk proteins are burned away. It does not have any hydrogenated oils so it is free of trans- fats and preservatives.
• Even today ghee plays an important role in ayurvedic remedies and medicine. During the early days when science had yet to develop creams for burns and blisters, ghee was applied and proved to be a cooling effect on the burns and blisters.
• It is believed that ghee stimulates the secretion of stomach acids and thus aids indigestion. Ghee is known to prevent the formation of ulcers and prevents constipation. Using ghee in our diet encourages good skin and healthy eyes.
• It is said to be beneficial in an improved memory and ability to learn. Ghee has a number of anti oxidants which help in strengthening the immune system and retards ageing.
• Ghee does not turn rancid while cooking due to its high smoke point that is between 400 – 500 degrees F. It does not need refrigeration as it has a very long shelf life.
As we all know that ghee has large amounts of saturated fat, so used in excess can lead to high cholesterol resulting in heart problems. 4 teaspoons of butter constitute 1 teaspoon of ghee. It has to be used prudently, moderately and wisely to gain all the benefits one can, from this pale yellow liquid gold.
