“Cholesterol is cholesterol,” says Rupy Aujla, a doctor who produces podcasts and cookbooks as The Doctor’s Kitchen. What people actually mean when they talk about good and bad cholesterol is how cholesterol is carried through the body, by particles called lipoproteins. How to lower your cholesterolIf you do need to lower your cholesterol, diet is one of the best places to start. Simply eating less food, says Aujla – about 5 to 10% fewer calories than you need – has also “been shown time and time again to reduce your LDL cholesterol”. Exercise and cholesterolExercise is a powerful tool to help you keep cholesterol levels in check.
