Healthy Food Quiz: Questions and Answers to Help You Fight Disease

Most people know that calcium is good for bones, fiber is good for constipation, and iron is good for blood, to name a few. But once you go beyond the basics, the picture gets murky.

Here’s a healthy food quiz (questions and answers included) to see how well you know which foods or nutrients can prevent or promote which diseases.

Feel free to cheat. The questions aren’t really a test of how well you read (and remember) every issue of Nutrition Action. They’re just a sneaky way to get you to look at the answers, which contain a wealth of information on how your diet affects your health.

Healthy Foods to Eat on a Gluten-Free Diet

Stomach pain, diarrhea, weight loss. Those are some of the symptoms of celiac disease, which is an autoimmune reaction to gluten, a protein found in wheat, barley, and rye.

At least one out of 100 Americans have celiac. Most of them don’t know it. And studies suggest that some people who don’t have the disease still can’t tolerate gluten. So what are some healthy foods to eat on a gluten-free diet?

First, let’s answer a few questions with Dr. Joseph Murray, a gastroenterologist and professor of medicine at the Mayo Clinic in Rochester, Minnesota.

Is Paleo Healthy? Should We Be Eating Like Cave Men and Women?

“If it wasn’t on a caveman’s menu, it shouldn’t be on yours.” That’s the basic premise of a Paleo diet. The question remains, as it should for any diet—is Paleo healthy?

Maybe you’ve heard of the Nordic diet, the Mediterranean diet, and more recently, the gluten-free diet, but these are all very different from the primal diet known as Paleo.

But is the Paleo diet healthy?

Do Intermittent Fasting Benefits Include Living Longer?

“We’ve known for a long time that if you reduce the calorie intake of rats or mice, they live much longer,” says Mark Mattson, chief of the laboratory of neurosciences at the National Institute on Aging (NIA) in Baltimore. Do these intermittent fasting benefits carry over to humans?

What happens in species closer to humans is more complicated. Rhesus monkeys fed 30 percent fewer calories lived longer in a study at the University of Wisconsin, but not in a study at the NIA.
