Healthy foods you should start eating in 2015

If you've pledged to eat better in the New Year, there are some foods to keep on your radar screen.

Dietitians predict they'll move closer to the mainstream this year.

One is watercress. It has the most nutrients of any fruit or vegetable and it can be used in salads and other dishes.

Broccoli sprouts are also trendy, for their high levels of a cancer-fighting enzyme.

And bean-based pastas are also getting attention.

Registered Dietician Kristin Kirkpatrick, explains, "Why is this a great option? Because the fiber is through the roof on these pastas, they are gluten-free, so they will satisfy a gluten-free diet, and they're much higher in protein."

On the beverage side, there's matcha tea - a finely milled, high-quality green tea packed with antioxidants, and a relaxing compound called L-theanine.

Finally, get ready to see more crickets - and not just coated with chocolate. They add protein to flour and thickeners.
