Normal cholesterol levels are best reached by losing weight and quitting smoking, as well as including more soluble fiber in the diet, which is accomplished by eating more vegetables and fruits. Consuming fewer meat and dairy products is also extremely beneficial, according to the Mayo Clinic.
Some people are at a greater risk for high cholesterol due to genetic factors. This can occur even with a healthy diet and lifestyle. In some cases, medication may be needed to control high cholesterol levels. The Mayo Clinic recommends that adults have a baseline cholesterol test at age 20 and continuous testing every five years for optimal cholesterol control.
