okay, so the other day my dad said that from tests he had done that his cholesterol is a little on the high side. I don't know if exercising helps reduce cholesterol levels but he walks almost everyday when he can around 4-5km and he is always busy working outside around the house, or part time at his job (he is retired now but works occasionally). my questions: are there actually any foods that can help lower cholesterol levels, and what foods could he eat that would not affect his cholesterol levels so much?
