Reducing your risk of heart disease

February is Heart Month, an ideal time to assess your risk of heart disease and take steps to improve your health. This is important because heart disease, sometimes called coronary artery disease, is the leading cause of death among adults in the United States. It is responsible for nearly 600,000 deaths each year, mostly from heart attacks. Millions more are at increased risk because of certain biological and behavioral risk factors.

Identifying your personal risk for heart disease and making efforts to improve your heart health is the topic of my Health & Fitness column in the Aiken Standard this week.

Some of these risk factors cannot be changed, such as age, sex, and family history, while others can be altered to reduce risk. These modifiable risk factors include smoking, high blood pressure, high cholesterol, diabetes, obesity, and physical inactivity. While your doctor can play an important role in treating these conditions, there is much you can do on your own to improve your heart health.

The first step is to get a good assessment of your heart health. If you haven’t done so recently, you should see your doctor to have your risk factors evaluated. This includes tests for blood glucose and blood lipids (including total, LDL, and HDL cholesterol and triglycerides), measurement of your blood pressure and body weight, and an assessment of other health factors such as your family history, whether you smoke, and your level of physical activity.

The next step is to treat the risk factors that you have. Depending on the severity and your own personal health history your doctor may prescribe medications to lower your blood pressure, blood glucose, or blood lipids. These medications are most effective when combined with lifestyle changes including good nutrition, exercise, and weight loss. In some cases, poor diet and lack of activity can counteract the beneficial effects of these drugs. Furthermore, these healthy habits may help you reduce the dosage, and limiting the side effects, or stop taking the medications altogether.

The other risk factors—obesity, inactivity, and smoking—really must be treated through lifestyle management. While there are medications that can help with smoking cessation and weight loss, being successful requires making lasting behavior changes. These habits can be difficult to change, and many people have tried before without success. Keep in mind, though, that everyone who is successful at quitting smoking, losing weight, or sticking to an exercise program has experienced his or her share of difficulty. The difference is that those people kept trying until they were successful. You can be successful, too.

Even small changes can have a big impact. Take exercise, for example. The benefits of as little as 30 minutes of physical activity per day are well established and impact heart disease risk in a multitude of ways. Physical activity helps with weight control, lowers blood pressure, improves blood lipids, and prevents and treats diabetes. Think of this as a great health “deal.” By modifying one risk factor—inactivity—you can also promote beneficial changes in four others—obesity, hypertension, high cholesterol, and diabetes. There is no other treatment, drugs included, which can have such a broad impact on reducing heart disease risk!

Of course, there are steps you can take beyond becoming more physically active to reduce your risk of heart disease. The list of beneficial changes you can make to improve your heart health is long, but keep in mind that even small changes can add up to a big benefit. 

Knowing which risk factors are most concerning can help you and your doctor make effective treatment decisions. Quitting smoking, increasing your physical activity (and reducing sedentary time), and eating a healthier diet can lead to improvements in heart disease risk factors and reduced heart attack risk. The best news is that these same changes can also reduce your risk of other serious health problems including many types of cancer, stroke, and lung disease.

 

 

Go Nuts (again)!

My Health & Fitness column in the Aiken Standard this week is about the health benefits of nuts. It is  a follow-up to a blog post I wrote a few weeks ago. This isn’t new, of course, since nut consumption has been recommended as a part of a healthy diet for years.

What is new is a recent study in the New England Journal of Medicine that shows that nut consumption was associated with a reduced risk of death from heart disease, stroke, and some cancers. The people who ate nuts every day got the biggest benefits.

That doesn’t mean that simply adding nuts to an unhealthy lifestyle will have some magical influence on health. In fact, the people in the study who ate the most nuts were also likely to do other healthy things like eat more fruits and vegetables, exercise, and not smoke.

The most practical advice is to eat nuts as a replacement for other snacks or to add nuts to salads and other dishes. While specific types of nuts have different health benefits, the recent study suggests that all nuts, including peanuts, are beneficial.

Go Nuts!

A new study suggests that going nuts is good for your health. Published in the New England Journal of Medicine this week, the study shows that regular nut consumption is associated with a lower risk of death from many leading causes of death, including heart disease and cancer. (If you aren’t motivated to read a journal article, this video will give you the key points from the study.)

The reduction of risk was greater with more frequent nut consumption. For example, the risk of death from all causes was 11% lower among men and women who consumed nuts once per week and 20% lower among those who consumed nuts seven or more times per week. 

This is level of nut consumption could be met by a common recommendation to consume 1–1.5 ounces of nuts as a snack every day.

One thing to keep in mind is that the health benefits of nut consumption might be due to other positive lifestyle factors that go along with greater nut consumption. Indeed, the authors noted that, “As compared with participants who consumed nuts less frequently, those who consumed nuts more frequently were leaner, less likely to smoke, more likely to exercise, and more likely to use multi-vitamin supplements; they also consumed more fruits and vegetables and drank more alcohol.” Although these other factors were controlled for in the study, common sense suggests that the reduction in risk is due to a combination of beneficial health behaviors.

This is an important point. A person who eats in unhealthy diet, is sedentary, and smokes is unlikely to realize the  health benefits of increasing nut consumption. Achieving the full benefits of nut consumption also certainly means adopting other healthy behaviors.

This is good news! Eating more nuts is a relatively easy dietary change to make. And as this study shows, it can lead to a reduced risk of death from some common diseases. So…go nuts!

When fat attacks! And how to win the battle.

My Health & Fitness column in the Aiken Standard this week is about fat. It turns out that fat is far more than just a place to store extra calories. Fat has metabolic and physiological effects that can promote disease, including diabetes and heart disease. And that is how your fat can attack you.

But regular exercise can offset or reverse many of the negative effects of excess fat. This is why people who are “fat but fit” may fare better than people who have a normal body weight, but don’t exercise.
