Cooking oils and trans fats: what actually helps your cholesterol
Which oils behave better for your heart, why trans fats are worth avoiding specifically, and practical swaps for Nigerian cooking.

Not all fat behaves the same way
The type of fat matters more than the total amount for cholesterol specifically. Unsaturated fats, found in groundnut oil, olive oil, fish and avocado, tend to be neutral or even help your numbers. Saturated fat, found in a lot of red meat, butter and palm oil used heavily, raises LDL when eaten often. Trans fat is the one worth actively avoiding.
Why trans fat specifically earns its bad reputation
It's mostly found in some margarines, shortenings and reused or heavily processed frying oil, and it uniquely both raises the 'bad' LDL cholesterol and lowers the 'good' HDL at the same time, a combination no other fat manages. It shows up most in repeatedly reheated deep-frying oil and some packaged snacks and baked goods.
The oil swap that actually matters
Using groundnut, sunflower or olive oil in sensible amounts, and not reusing frying oil more than once or twice, does more for your numbers than agonising over an exact brand. Grilling, boiling or air-frying instead of deep-frying, where the taste difference is small, is an easy, low-cost swap.
A realistic starting point
You don't need to remove all fat; a completely fat-free diet isn't the goal or even healthy. The practical shift is toward fish, beans and vegetable oils more often, and away from reused frying oil and heavily processed snack foods, most days rather than every single day.
