The best multivitamins and what they should contain

Have you bought multivitamins lately? Have you heard they can prevent a cold? Or perhaps that multivitamins are useless? Or that they could even lead to a shorter life? There’s certainly a ton of debate.

It can be pretty confusing, to say the least. There are multivitamins for every age group, for men and women, some that are for athletes, and some for the weekend warrior.

Some multivitamins contain extra Vitamin D, or C, or Calcium, or Iron. Then, of course, there are name brands and store brands. How can you tell which multivitamins are the best multivitamins?

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.

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.

Magnesium-Rich Foods to Prevent a Stroke

More magnesium may mean a lower risk of stroke.

Researchers looked at seven studies that followed a total of roughly 240,000 people for eight to 15 years. The risk of an ischemic stroke was 9 percent lower for each 100 milligrams of magnesium the participants reported eating per day. This may seem like a low number, but simple changes or additions in diet may offer complementary benefits. Preparing foods to prevent a stroke will often coincide with eating foods that are good for your overall health.
