Join us for a special webcast: “Rethinking Cholesterol”
If the latest information on health and wellness is important to you, you will not want to miss a special live-streamed webcast, “Rethinking Cholesterol,” which will be aired on Thursday, September 24, from 12:30pm to 1:30pm Eastern time. The webcast, which is free to all viewers, is co-sponsored by Reuters, Harvard Health Publications, the Harvard T.H. Chan School of Public Health, and Harvard Medical School.
Recent science has brought new insights into the importance of controlling cholesterol for maintaining cardiovascular health. LDL (low-density lipoprotein) cholesterol is a potent risk factor for heart and blood vessel disease. New research suggests that when it comes to protecting your heart, the lower your LDL cholesterol, the better.
How you can lower your cholesterol
There is much you can do with your diet to lower LDL cholesterol. Mainly, it is critical to reduce your intake of saturated fat and trans fat. These two forms of fat drive up LDL levels. Saturated fat is found in butter, cheese, other dairy products, and red meat. Trans fat is found in partially hydrogenated oils. By law, trans fats are supposed to be removed from all commercially prepared foods within the next three years. But until then, you need to carefully read food labels to avoid trans fat.
It is best to replace saturated and trans fat with polyunsaturated fats (soybean, corn, and sunflower oils) and monounsaturated fats (olive oil), which lower LDL levels. But you might be surprised to learn that cutting back on cholesterol-rich foods is of little help. Most cholesterol in your bloodstream is produced by the body and does not come from your food. Getting plenty of fiber may also help to lower cholesterol levels. Regular exercise is also important because it helps you control body weight and can raise levels of HDL (high-density lipoprotein) cholesterol, which helps sweep fat from the bloodstream.
When you need a little more help than lifestyle changes alone
If diet and exercise don’t bring your cholesterol down to a healthy level, there are medications that can help. Statins have been the mainstay of drug therapy to lower LDL cholesterol. Statins are sometimes given in combination with ezetimibe, a drug that reduces cholesterol absorption in the intestine.
Powerful new medications, called PCSK9 inhibitors, have just recently become available. These medications are antibodies that promote the removal of LDL cholesterol from the bloodstream into the liver, where it can be processed. PCSK9 inhibitors can dramatically lower LDL cholesterol to levels not previously seen with other medications. But they must be given by injection under the skin, and currently, they are very expensive. Only time will tell if these low LDL levels translate into lower risk of heart and blood vessel disease, and if there may be unexpected side effects from driving LDL cholesterol levels so low.

The type of fat you eat matters!
By: JoAnn E. Manson, MD, DrPH, and Shari S. Bassuk, ScD
Contributing Editors, Brigham and Women’s Hospital, Harvard Medical School
If you saw last month’s news headlines declaring that saturated fat is no longer deemed harmful to your heart, you may be (understandably!) confused. After all, for years, clinicians and scientists have recommended reducing saturated fat for heart health. Is it time to rethink this advice? Hardly. Here’s the deal.
The research that sparked the recent news splash was an analysis by Canadian researchers of up to a dozen long-term observational studies of diet that included a total of 90,000 to 339,000 participants from various countries. These study volunteers reported on the foods they typically ate. Researchers then tracked the health of these folks for years, sometimes decades. The analysis found no association between consumption of saturated fat — dairy foods (e.g., cheese, butter, and milk) and meats are two main sources — and future risk of coronary heart disease, ischemic stroke (strokes resulting from a blocked vessel), diabetes, or deaths from cardiovascular disease or all causes. Less surprisingly, the analysis also found that trans fats are harmful to health, with the highest intakes of trans fat linked to a 21% higher risk of coronary heart disease and a 33% higher mortality rate compared with the lowest intakes. The findings were published on August 12 in the medical journal The BMJ.
Unfortunately, the news coverage of this analysis often missed a key point. It’s not just the amount of saturated fat you eat, it’s also what you replace those calories with (the quality of your overall diet) that affects your health. Most people naturally tend to keep their calorie intake at a constant level over time (scientists call this “calorie preservation”). If they cut saturated fat calories out of their diet, the missing calories have to come from somewhere else (“calorie substitution”). People with lowered saturated fat intake may replace those calories with other unhealthy foods such as refined carbohydrates (e.g., white bread, white rice) or sugary beverages. So although they are eating less fat, their overall diet is no better — and may even be worse — than people who don’t try to limit saturated fat. .
Numerous studies show that substituting unsaturated fat — found in fish, nuts, and plant oils — for saturated fat improves health. For example, a careful analysis of observational findings from the Nurses’ Health Study, in which my colleagues and I (JEM) tracked 80,000 initially healthy female nurses for many years, suggested that replacing just 5% of calories from saturated fat with calories from unsaturated fat cuts risk of coronary heart disease by 42% and is more effective at preventing heart attacks than simply reducing overall fat intake. Short-term dietary trials also show heart benefits of lowering saturated fat intake while boosting unsaturated fat intake, including improvements in blood cholesterol levels and insulin sensitivity.
The most harmful type of dietary fat is trans fat, also known as partially hydrogenated vegetable oil. These fats are a double whammy: they boost the “bad” LDL cholesterol and lower the “good” HDL cholesterol. New government regulations are reducing the presence of artificial trans fats in the food supply, but such fats are still found in many products. What’s the take-home message? The type of fat does in fact matter, so choose foods with healthy unsaturated fat (fish, nuts, and most plant oils), limit foods high in saturated fat (butter, whole milk, cheese, coconut and palm oil, and red meats), and try to avoid foods with trans fat. Achieving the last goal can be tricky. In supermarkets, check package labels carefully. The best way to tell if trans fat is present is to read the ingredient list; if the phrase “partially hydrogenated oil” appears, then trans fats are indeed lurking.
Many experts and professional societies, including the American Heart Association, advise a dietary pattern that (1) emphasizes vegetables (richly colored vegetables, including dark leafy greens, are best, and white potatoes don’t count), fresh fruits, and whole grains (whole-grain cereals, breads, rice, and pasta); (2) includes fish, beans, nuts and seeds, poultry, low-fat dairy products, and non-tropical plant oils (such as canola or olive oil, but not coconut or palm oil); and (3) limits sweets, sugary drinks, and red meats. Well-known examples are the Mediterranean and DASH diets. People who eat such diets have consistently had much better health outcomes than those who do not.
