What is carbohydrate?

Carbohydrates, or carbs, are one of the three main nutrients in food. They include sugars, starches and fibre, and your body breaks most of them down into glucose, its main source of energy.

Carbohydrate: one of the three main nutrients in food.

Why carbohydrate matters

Carbs aren't bad, but the type and amount matter, especially if you have diabetes or prediabetes.

  • Added sugar and refined starches like maida, white bread and sweets raise blood sugar quickly.
  • Whole grains, pulses and vegetables are digested more slowly and bring fibre, vitamins and minerals with them.

MedlinePlus says that on average about 45 to 65% of daily calories come from carbohydrates, though your own needs depend on your age, health and goals.

Carbohydrate in Indian food

Swap refined grains for whole ones: whole-wheat atta, jowar, bajra, ragi, dalia and brown rice.

Keep portions of rice and roti moderate and pair them with dal and vegetables, which slows the rise in blood sugar.

Limit added sugar in:

  • chai
  • sweets
  • biscuits
  • packaged juices

Choose whole fruit instead. If you're thinking of trying a low-carb diet, or you take diabetes medicine, talk to your doctor first.
