We like to ask our board members a few questions that are on our minds. Here are a few of Dr. Swartzberg's answers.

If you could give only one piece of advice to a friend or patient to make their health better, what would it be?
Besides stop smoking, exercise, and eating healthfully? Those are givens. My other piece of advice is to spend time strengthening your relationship with friends and family. You'll benefit physically and mentally. And no one approaches old age and wishes they has spent less time with the people they love.

What one thing can someone do in 15 minutes a day that makes the world a better place?
Encourage at least one different person a day to follow my advice in Question 1.

Do you take supplements, and if you do, which ones?
Because I don’t think I get enough calcium and vitamin D in my diet, I take those supplements. I try to get the rest of my vitamins and minerals through healthy food.

What health advice do you tell other people that you don’t follow yourself?
I don’t wear sunscreen on a regular basis and I know I should. I just don’t like to put creams on my body. I have one sunscreen that’s really cool. It’s a sunscreen with zinc oxide that you put on with a brush. It sits in my bathroom drawer but I never put it on. I don’t know why.

What’s your favorite food indulgence?
I love nuts. Never salted. Usually roasted. Nuts have high oil content, so a quarter cup—a handful really— can have nearly 200 calories. But they’re delicious, healthy, and filling, so I indulge.
