The Role of Fat in the Diet

Hi friends, How are you all?Hopefully everybody is well.I am also well by the grace of Almighty.Today I want to discuss about the role of fat in our diet.So let's start,🤗

The Role of Fat in our Diet:

Source of energy :

Fat is the most concentrated source of energy in the diet.Each gram of fat releases 9 kcals of energy,when completely oxidised to carbon dioxide and water.

Satiety value:

Fat tends to leave the stomach relatively slowly.It can still be released from the stomach for upto 3.5 hours after a meal with the precise time depending on the size and composition of the meal.This prolonged stay in the stomach helps to delay the onset of hunger pangs and so contributes to a feeling of satiety after a meal.Due to this,moderate fat reducing diets are currently considered more successful in weight control than very low fat diets.

Carrier of fat soluble vitamins:

Dietary fat serves as a carrier for vitamins A,D,E and K.Also fat at a level of at least 10 percent of total energy intake appears to be required for the absorption of vitamin A precursors from non fat sources such as carrots.Anything that interferes with absorption or use of fat such as obstruction of bile duct depresses the supply of fat soluble vitamins to the body.

Palatability:

The presence of fat in food or its addition to food is responsible for much of the texture and flavour of food. The marbling of fat throughout the lean muscle of a steak contributes greatly to its tenderness and flavour.Frying improves the taste of food.Many of the substances that are responsible for the flavours and aromas of foods are soluble in fat so that fat tends to carry these flavours and aromas and mix them throughout the food as a whole.
