Question

Write a detailed note on types of fats. 

Answer 1

1. Saturated fats: Solid at room temperature. Mainly found in animal foods such as ghee, butter, cheese, cream, red meat and full-fat dairy products, and in coconut and palm oil. Too much saturated fat increases blood cholesterol.
2. Unsaturated fats: Liquid at room temperature. Mostly obtained from plant oils and generally improve cholesterol levels. They are of two types:
   • Monounsaturated fats: present in canola, olive and peanut oils; lower bad LDL cholesterol and maintain good HDL cholesterol.
   • Polyunsaturated fats: present in sunflower, soyabean and corn oils; lower bad LDL cholesterol.
3. Trans fats: Unsaturated fats changed by hydrogenation. They are present in processed foods, snacks, cookies and some margarines. Trans fats raise cholesterol and should be eaten as little as possible.
