Is Hydrogenated vegetable fat bad for you?
Also listed as: partially hydrogenated oil, vanaspati, bakery shortening, trans fat
Short answer
Partially hydrogenated fats are the main source of industrial trans fat, the most harmful fat for your heart. Avoid them where you can.
What it is
Liquid vegetable oil made solid by adding hydrogen. Partial hydrogenation creates trans fats.
Where you’ll see it
Vanaspati, some bakery products, puffs, fried street snacks, biscuits and older-style margarines.
+ The good side
- Cheap and long-lasting for frying and baking
- India now limits industrial trans fat in oils and fats to 2% of total fat
− The other side
- Trans fats raise LDL (‘bad’) cholesterol and lower HDL (‘good’) cholesterol
- Repeatedly reused frying fat can be worse
Who should pay attention
Everyone, especially people with heart disease risk.
💡 What to do: Look for ‘trans fat: 0 g’ in the nutrition table and avoid ‘partially hydrogenated’ in ingredients.

Palm oil
Fine occasionally, but it is about half saturated fat, so a diet heavy in palm-oil foods can raise LDL cholesterol compared with oils like groundnut, mustard or olive oil.
Maida (refined wheat flour)
Not harmful in itself, but it has had most of the fibre and many nutrients removed, so it raises blood sugar faster and keeps you full for less time than whole wheat.
