level can be incaresed by various methods.
1)Exercise-Many people don't like to hear it, but regular aerobic exercise
(any exercise, such as walking, jogging or bike riding, that raises your heart rate
for 20 to 30 minutes at a time) may be the most effective way to increase HDL levels. Recent evidence suggests that the duration of exercise, rather than the intensity, is the more important factor in raising HDL choleserol. But any aerobic exercise helps.
2)Lose weight. Obesity results not only in increased LDL cholesterol, but also in reduced HDL cholesterol. If you are overweight
, reducing your weight should increase your HDL levels.
3)Since u dont smoke and drink, its one of the best ways to increase ur HDL level..
Increase the monounsaturated fats in your diet. Monounsaturated fats such as canola oil, avocado oil, or olive oil and in the fats found in peanut butter can increase HDL cholesterol levels without increasing the total cholesterol
Decrease the amount of transfatty acid food consumption.
Add soluble fibers such as legumes, oats , vegetables to ur diet.
Other methods by which HDL level can be increased are by consuming Fish and other foods containing Omega 3 fatty acids.
Hope this helps!!
