What is dietary fat?

Dietary fat is the fat in the food you eat, from oils, ghee and butter to nuts, seeds, milk, meat and fish. Your body needs some fat to work properly, so it isn't something to cut out completely.

Dietary fat: the fat in the food you eat, from oils, ghee and butter to nuts, seeds, milk, meat and fish.

Why dietary fat matters

Your body needs fat, but it is very energy-dense and the type you eat matters.

What fat does:

  • forms the walls of many of your cells
  • helps you absorb vitamins A, D, E and K
  • helps you feel satisfied after a meal

It's very energy-dense: Cleveland Clinic notes that every gram of fat has 9 calories, more than double the 4 in a gram of carbohydrate or protein, so a heavy hand with oil adds up fast.

The type matters as well:

  • Unsaturated fats from nuts, seeds, fish and most vegetable oils are the better choice.
  • Too much saturated fat and any trans fat raise your heart risk.

Dietary fat in Indian food

Use less oil and choose better fats.

In the kitchen:

  • Measure cooking oil with a spoon rather than pouring from the bottle.
  • Use liquid oils like mustard or groundnut for everyday cooking.
  • Enjoy ghee in small amounts rather than generous dollops.

Cut down on:

  • deep-fried snacks
  • bakery items
  • anything made with vanaspati

Get good fats from a small handful of nuts, alsi or til seeds, and fish if you eat it.
