The rule of thumb is to replace saturated fats with unsaturated fats where possible, advises cholesterol charity Heart UK.
Many foods contain saturated fat, especially animal foods such as meat, butter and dairy products, and foods that are made with them, such as cakes and biscuits.
They’re also found in some plant foods including coconut oil and palm oil.
Good sources of unsaturated fat include plant-based fat spreads and oils, oily fish, nuts and seeds.
