Baker IDI Healthy Cholesterol Diet and Lifestyle PlanThe Baker IDI Healthy Cholesterol Diet and Lifestyle Plan will help you manage your cholesterol levels and improve your health. Cholesterol is widely known, but little understood.

Around one in three Australian adults have abnormal cholesterol levels, but only one in ten are aware of this.
