As a doctor, I want to get a few things straight, Mr. President.

Right, left, or in-between, our country needs you. Your wife and girls need you. They need you in good health, and setting a good example, not least because talking about healthcare is so much more credible when we do what we can to not need it.

Here’s the bad news: You have not one, but two risk factors for heart disease: smoking and high cholesterol. You’re not a teenager anymore. It’s time to take this seriously.

The good news—great news, in fact—is that you can change them both. But frankly, I’m worried. If you have had trouble sorting out smoking and cholesterol, then millions of other Americans must be in the same boat, which is to say completely in the dark about the very same problems.

So let me lay it on the line:

First, smoking. Tobacco is a tough habit to break. I know. When my hospital banned smoking, I wondered how the doctors would take it—after all, the doctors’ lounge had a dull haze 24/7. But we broke that habit, and so can you. There is no magic here. Just keep trying until you quit for good. And it gets easier every day that goes by without a cigarette.

Second, cholesterol. Here, let’s clear up a few myths.

First, exercise won’t lower your cholesterol. It may bump up “good” cholesterol slightly and improve your basketball game or your stride, but you definitely can’t count on it to lower your “bad” cholesterol. It won’t.

Second, we almost certainly cannot blame genes. For the vast majority of people, high cholesterol comes down to diet.

Third, switching from beef to chicken and fish has almost no effect on cholesterol. It lowers “bad” cholesterol only about 5 percent–and that’s not enough.

The answer is behind your house, in the White House garden. Foods from plants have essentially no cholesterol and are free of the animal fat that causes the body to make cholesterol. If you skipped meat, dairy products, and eggs for even a few weeks, chances are your cholesterol would drop right into the normal range.

What’s that? You love burgers and chili? Fair enough. So make it a veggie burger. And I can show you a vegetarian chili that is so good, you’ll never know the difference.

And when you conquer your health demons, you’ll inspire every American child to do the same. Lest you think this is a trivial issue, one in five teens has an abnormal cholesterol test today, according to the Centers for Disease Control and Prevention. And it only gets worse as they reach adulthood. One in three children is overweight, and one in three will eventually develop diabetes.

You can help them by stubbing out the smokes for good and adopting a healthy, plant-based diet. And as a shining example of good habits, you will have done more good for the health of the American public than any prior president.

People may disagree on how to make healthcare work. But I hope that a bit of advice on how to be healthy will reduce the risk you’ll ever need it, and help you stay well and strong. That’s food for thought.

Meatless Monday is the perfect day to take a look at the connection between our health and diet. Read on to learn more about the state of America’s health and Neal Barnard, MD’s prescription for wellness.

Rush Limbaugh was rushed to a Hawaii hospital in late December, reportedly suffering from severe chest pains. The concern was a possible heart attack, but fortunately, tests showed no such problem.

This health scare should still be a wake-up call. As a doctor, I’m offering one bit of advice, not just to Rush, but to all Americans: We need to be more conservative. As conservative as possible, in fact.

With our diets, that is. Many Americans are far too liberal with their servings of meat, dairy products, eggs, and other less-than-healthy foods. And they are getting more so with each passing year. Per capita annual meat intake has risen roughly 70 pounds in the last century, and cheese intake has jumped by nearly 30 pounds in the same time period.

This huge load of cholesterol, fat, and calories has fueled epidemics of obesity, heart disease, diabetes, and other health problems. And these diseases are taxing our health care system like never before. As a nation, we now spend $147 billion on obesity-related medical costs every year. During these tough economic times, we should be tightening our belts. But let’s face it: Our belts are rapidly moving in the opposite direction.

In our grandparents’ day, people knew the value of humble beans, vegetables, and fruits, often growing them in their own family gardens. These foods have essentially no cholesterol and very little saturated fat. It pays to give them renewed respect. Indeed, people who stick to an entirely plant-based diet, as part of an overall healthy lifestyle, can do more than just prevent heart disease; they can actually reverse it, as was demonstrated in the now-classic studies of Dean Ornish, M.D.

A plant-based diet can also help you slim down, improve diabetes and hypertension, and feel like yourself again. It can also fight some types of cancer. Fruits and vegetables are packed with antioxidants and other nutrients that boost the immune system. And fiber-rich vegan diets help quickly flush carcinogens and other toxins from the body.

The only good thing about a health scare is that it reminds us how important our diets and lifestyles are to our well-beings. It’s time to trade our cheeseburgers for veggie burgers, beef tacos for bean burritos, and remote controls for tennis shoes. Yes, that’s my prescription for Rush—but it’s also my prescription for us all.
