When cholesterol starts creeping up past 200

When total cholesterol begins to creep up past 200 mg/dL, it’s time to change diet [1]. If it reaches 240 mg/dL or higher, then the body is at high risk of coronary artery disease and cardiac death [1]. The risk is only accentuated if LDL cholesterol is higher than 160 mg/dL and HDL cholesterol is lower than 40 mg/dL (50 for women) [1].

So, what can be done? Takng cholestyramine and colestipol will help promote excretion of bile [2]. The “statins” atorvastatin, lovastatin and simvastatin can block key enzymes that synthesize cholesterol [2]. Even niacin in the form of nicotinic acid can help through its effects on widening blood vessels [3]. But the benefits of these drugs and the vitamin are extremely limited, because if treatment is stopped, cholesterol can and probably will go back up again unless there is a change of diet [4]. The drugs can also have possible side effects such as liver damage, muscle pain and break down, and kidney problems [4].

A change in diet and lifestyle is most important. Regular exercise, particularly aerobic exercise, increases HDL cholesterol, which in turn helps to lower total cholesterol and LDL cholesterol [5]. In addition, according to Mayo Clinic, the top five foods for lowering cholesterol are oat bran (soluble fiber), nuts, fish oil, olive oil, and plant sterols [6]. Soluble fiber included with meals may reduce absorption of cholesterol, nuts like walntus and almonds can replace high-saturated fat and high-cholesterol foods because their lipid profile includes PUFAs, fish helps to lower TGs through its content of omega-3 oils, olive oil PUFAs and antioxidants help (avoid lite olive oil), and plant sterols block absorption of cholesterol [6].
