Americans are making shifts in the supplements they take -- fewer multivitamins and vitamins C and E, more fish oil and vitamin D. Many think of supplements as magic bullets, but studies don't always support their supposed benefits.

Some research is positive. Vitamin D is important for good health and very hard to get naturally from foods or, if you live in northern latitudes, from th...

The guidelines to eat more vegetables are clear, and eating a rainbow of colors gets you the widest variety of nutrients and phyto-nutrients, those hard-to-duplicate compounds that go beyond vitamins and minerals.

But whether you're at the farmers' market or choosing a side dish at a restaurant, are some vegetables better than others?

A research study set out to rank the bes...

Ounce for ounce and calorie for calorie, leafy greens and other types of vegetables are the hands-down favorites for delivering on nutrients. But many fruits should also have a place at the table.

Researchers looked at the most nutrient-dense fruits and vegetables to see which provided meaningful amounts of B vitamins including thiamin, riboflavin, niacin, folate, B6 and B12, vitamins...

In the ABCs of vitamins, B12 is often overlooked. But it's essential for the making of nerve and red blood cells, as well as DNA along with many other body processes. Adults and teens need just 2.4 micrograms a day, but you can fall short even on this small amount.

You're at particular risk of a B12 deficiency if you're a vegetarian because animal foods, like meat and dairy, are the o...
