My husband has a cholesterol problem can i make paratha for him in olive oil?

Of course: His physician may have recommended limiting certain fats; olive-oil is actually a feature of the much-praised "mediterranean diet" that is supposed to slow atherosclerosis. Diet isn't the first-and-foremost way to manage most health problems. Perhaps the nicest thing you could do for him is to take up aerobic fitness yourself and perhaps he'll join in -- let him think it's his idea. Best wishes.
