Diet & exercise. Moderate exercise (about 30 minutes 5 times a week) reduces LDL cholesterol and raises HDL cholesterol. Smoking can lower HDL levels, so stop smoking if you do. Eat lots of fruits, vegetables, whole grains and lean sources of protein. Include monounsaturated fats in your diet- olive oil/canola oil. Moderate consumption of alcohol may also positively impact HDL levels. 1 glass of wine a day.
Tough one! Really hard - u can perhaps move the HDL in percent terms but not real terms - this is how the drug companies sell their nonsense - if your HDL is 30 - thats low - and you take drug "x" - it goes up to 33 - wow thats 10% - but, only 3 points and still low - standard answers are exercise, carb cutting, fish oil - and, the real kicker - saturated fat! too bad the LDL goes up with the last one!
