What is lassi?

Lassi is a thick drink made by churning dahi with water or milk. It comes sweet, salted (namkeen), or blended with fruit such as mango, and in Punjab it's often topped with a layer of malai.

Lassi: a thick drink made by churning dahi with water or milk.

Lassi and your health

Lassi carries the protein and calcium of dahi, but sweet versions can contain a lot of added sugar, and malai adds saturated fat.

About the sugar:

  • The natural sugar in milk and curd isn't the concern; added sugar is.
  • Adults are advised to keep free sugars to no more than about 30g a day.
  • A tall glass of sweet lassi can use up a large share of that in one go.

How to have lassi

Choose namkeen lassi with roasted jeera, or make a sweet lassi with less sugar and a little fruit for sweetness.

For a lighter glass:

  • skip the malai on top
  • use toned milk or curd

Treat a sweet or mango lassi as a snack in itself rather than a drink alongside a full meal.

If you have diabetes:

  • Plain chaas or salted lassi usually fits more easily.
  • Talk to your doctor or dietitian about where sweet drinks fit in your plan.
