If you smoke, it’s time to pack it in. According to the American Heart Association, smoking reduces your HDL cholesterol levels, while increasing your risk of heart disease, high blood pressure and diabetes. If you’re a smoker, you need to quit. Once you stop smoking, you can significantly improve your HDL cholesterol level very quickly and start protecting your heart. And if you’re a non-smoker, you need to avoid exposure to second-hand smoke to prevent your health from going up in smoke.
If you don’t already dust your cappuccino with cinnamon or shake pepper on your pasta, listen up: Spices like garlic, curcumin, ginger, black pepper, coriander, and cinnamon do more than flavor your food, they can also improve cholesterol. Research shows that eating a half to one clove of garlic each day could lower cholesterol up to 9%. Bonus: Adding extra seasoning to your food also reduces your appetite, so it’s easier to drop excess pounds, Steinbaum says.
A: Before I answer that question, why bother to increase HDL cholesterol at all? Many studies have found that people with low levels of HDL are at increased risk for heart attacks, strokes, and other complications of arteries diseased by atherosclerosis: that's why we call HDL the "good" cholesterol. Given that, you'd think that raising HDL levels would reduce a person's risk for atherosclerosis. Unfortunately, despite a lot of research, we don't yet know if that's true, nor how best to raise HDL levels.
But keep in mind that not all cholesterol is created equally. LDL cholesterol, also known as “bad cholesterol,” is the form that can build up on the artery walls and increase your risk of heart disease. HDL cholesterol, on the other hand, is often dubbed “good cholesterol” because it travels through the bloodstream, removing harmful cholesterol from the arteries to help enhance heart health.
Soy isoflavones significantly decreased serum total cholesterol by 0.10 mmol/L (3.9 mg/dL or 1.77%; P = 0.02) and LDL cholesterol by 0.13 mmol/L (5.0 mg/dL or 3.58%; P < 0.0001); no significant changes in HDL cholesterol and triacylglycerol were found. Isoflavone-depleted soy protein significantly decreased LDL cholesterol by 0.10 mmol/L (3.9 mg/dL or 2.77%; P = 0.03). Soy protein that contained enriched isoflavones significantly decreased LDL cholesterol by 0.18 mmol/L (7.0 mg/dL or 4.98%; P < 0.0001) and significantly increased HDL cholesterol by 0.04 mmol/L (1.6 mg/dL or 3.00%; P = 0.05). The reductions in LDL cholesterol were larger in the hypercholesterolemic subcategory than in the normocholesterolemic subcategory, but no significant linear correlations were observed between reductions and the starting values. No significant linear correlations were found between reductions in LDL cholesterol and soy protein ingestion or isoflavone intakes.
Because increasing HDL levels is thought to be such a beneficial thing, and because there is no easy or reliable way to do so, developing drugs that substantially raise HDL levels has become a major goal for several pharmaceutical companies. And indeed, several of these drugs have been developed, and have led to clinical trials to demonstrate their safety and efficacy.
Flavor foods with herbs and spices whenever you can. It’ll help you cut back on condiments high in saturated fat while maximizing flavor. Spices and herbs also pack antioxidants, which can help improve cholesterol levels when combined with veggies. Ones we love: Basil, cilantro, rosemary, sage, ginger, garlic, tarragon, black and red chili pepper, mint, and oregano.
