Hi, thanks for using healthcare magic
can be related to family history, diet, low physical activity. It can be modified by dietary changes, you already consume alot of vegetables, lean meat and low diary, the only other changes would be increasing use of other fiber. This would include the use of whole wheat products, barley, flax seeds, brown rice/pasta/flour instead of white, use of fish such as salmon/tuna/sardines, use of oils with more monosaturated fat.
Increased in physical activity would be helpful, it it recommended that persons exercise at least 150 mins a week.
Many persons require the use of medication to improve cholesterol despite using the recommended diet and physical activity.
I hope this helps
