Fat is a compound that is insoluble in water and is present in animals for a variety of reasons. It helps in insulating us from the cold, formation of hormones (that are absolutely essential for our survival), energy generation when we are starved and cushioning us from jerks and jolts. It is yellowish in colour, although one type of fat is brown.
Fatty food are meat, oil, cheese… and many animals products. These are good to eat however if not balanced with vegetables these lead to weight gain!
