Q: My doctor says I have high cholesterol. What can I do to lower it?
A: There are several components to a “lipid profile” – total cholesterol, LDL (“bad”) cholesterol, HDL (“good”) cholesterol and triglycerides. If your physician is telling you that you have “high cholesterol,” he is referring to either the total cholesterol number, your LDL reading or both. A desirable profile is as follows:
Total cholesterol <200 mg/dl
LDL cholesterol <130 mg/dl
HDL cholesterol >40 mg/dl (>50 mg/dl for women)
Triglyceride level <150 mg/dl
Cholesterol is a component of animal products and is not found in plant-based foods. It is necessary in the body for the production of bile, which helps digest fats, and steroid hormones (e.g. vitamin D, estrogen and testosterone). While the body utilizes cholesterol for important functions, the liver is also able to synthesize necessary amounts – it is not necessary to ingest it as part of your diet! Total cholesterol, LDL and triglyceride levels that are too high put you at risk for cardiovascular disease.
Let’s focus on LDL cholesterol, since it has been linked to atherosclerosis, coronary heart disease, heart attack and stroke. Several factors influence LDL levels, including age, diabetes, obesity, reduced estrogen levels and diet. Diets high in saturated fat and cholesterol elevate LDL. In addition, trans-fats can raise LDL and lower HDL (“good”) cholesterol – a double whammy!
Lower your saturated fat intake! Saturated fat intake has a much greater negative effect on blood cholesterol than does dietary cholesterol. (Dietary cholesterol, however, is often found in the same foods that are high in saturated fat.) Choose lean meats, select skim milk, low-fat dairy products and stick to vegetable oils that are liquid at room temperature (e.g. cook with olive or canola oil, rather than butter or lard.) To further cut back on fat intake, remove the skin from chicken before eating, substitute margarine for butter and grill or bake fish, meat and poultry instead of frying.
Eat a minimum amount of trans-fat. Select products that are made with no hydrogenated (or partially hydrogenated) vegetable oils. Check the ingredient list before buying!!
While there are several ways to manage blood cholesterol levels with medication, try modifying your diet first. Just a 1-point decrease in your LDL cholesterol level corresponds to a 1-2% decrease in your risk for developing coronary heart disease!
Q: Is there a difference between butter and margarine?
A: Yes! A quick look at the nutrition facts tells us there is a big difference between butter and margarine! The debate focuses on the types of fat found in these products and stick butter has the most saturated fat per tablespoon (7g), giving it the most unhealthy characteristics.
When it comes to eating a heart healthy diet, you want to minimize intake of artery-clogging trans-fat and saturated fat, both of which can raise your LDL (bad) cholesterol level. Keep trans-fat consumption to a minimum and saturated fat to less than 10% of daily calories. (That’s 20g saturated fat for a daily 2,000 calorie diet!)
Years ago, hard margarines were made with unhealthy hydrogenated oils. Hydrogenation is the process of taking unsaturated (healthier) fats and adding hydrogen atoms to obtain characteristics of a saturated fat. For example, hydrogenated oils are firmer and easier to spread, but this causes the loss of health benefits associated with unsaturated fats. Trans-fatty acids also form during hydrogenation and pose a double risk to heart health by raising LDL (bad) cholesterol AND lowering HDL (good) cholesterol. Thanks to better technology, soft margarines and spreads can now be made from a blend of unhydrogenated oils, such as soybean and canola oils, which are mostly unsaturated and, therefore, more heart healthy than butter.
While whipped butter has less saturated fat per tablespoon that stick butter (see below), soft margarine and spreads are clearly the way to go to save on calories and saturated fat grams! The bottom line? Check the ingredient list to make sure the product is not made with partially hydrogenated oils and look for spreads that are trans-fat free and low in saturated fat!
