Kelp is the new kale
Kelp, a tasty and nutritious variety of seaweed, is poised to become the new "it" green in your diet. "It's really high in protein. It has a lot of great B vitamins that are really hard to get," Brue said. Not convinced? She noted that it took a while for kale to catch on, too, but creative chefs helped make it hugely popular.
This Japanese green tea powder has been on trend-watchers' radar for several years, and is finally going mainstream. "A lot of coffee bars have it. A lot of baked goods have it, too," Gelula said. "Matcha is a green tea that comes in a powder form, you can really add it to a lot of things."
Dozens of companies are now making beverages loaded with antioxidants and other nutrients to help promote a healthy glow from within. "This is something you could have at your desk in powder form and just add to water. It's filled with lots of things you might have in your multivitamin, things like antioxidants," Gelula said. "This is a big thing we're going to see in 2016."
"These are also targeted for specific issues people might have, like anti-aging ... or anti-acne," Brue added.
Doctors call them "adaptogens," a category that includes herbs such as ginseng and the less-familiar moringa, maca and ashwaganda. "They're herbs that help the body adapt to stress," Gelula said. The therapeutic use of such plants dates back thousands of years.
Holistic health beats dieting
Rather than obsessing about calories or carbs, dieters are increasingly looking at the big picture of what it takes to live a healthy life. Brue noted that even Weight Watchers has a new program "focusing less on points and pounds and more on what it means to be healthy. That's more motivating for women."
No longer just a solo activity, meditation is becoming something to share. "A lot of millennials are getting together in groups to do this as part of their social life," Gelula said. "You might go to a large-scale event. In New York, we recently had one for more than 800 people in an auditorium. And it's young people, which is really heartening; they have stress-management tools early on. But they're also seeing it as a cool part of their lifestyle."
