1. So Old, They're New
Ancient grains from the farthest-flung soils are the ones flying off the shelves the fastest. They're heartier and more versatile than rice, and we love their earthy, toothsome flavors. Bob's Red Mill reports that in the past 3 years, sales of ancient grains have soared. Millet, a gluten-free grain, has tripled in sales. Sales of the heirloom wheat kamut have grown more than 10-fold!

2. Butter Me Up
Another nearly ancient classic? Peanut butter. But the peanut's not the only nut worth crushing. Finding new butterables wasn't a tough nut to crack for the can-do industry: The nut-and-seed-butter business has boomed 52 percent since 2011. Shelves are crowded with newcomers, and these are our favorites.

MaraNatha All Natural Coconut Butter. One in four new products in the food-and-drink world is coconut based, and you'll see why when you add a velvety dollop of this to your next smoothie, or melt it and drizzle over fresh pineapple. ($9; maranathafoods.com)

3. Dairy-Aisle Upgrade
We're spooning 113 percent more yogurt than we did in 2001, and thankfully, our tastes have evolved beyond syrupy fake fruit. Yogurt looks less like poorly disguised dessert every day. Our newest obsessions all have 16 g of sugar or less. (Add some excitement to your go-to snack with these 8 tasty yogurt add-ins.)

4. Raising the Bar
In the bar world, too, sweet is so last year--41 percent of consumers want more savory bars. Some brands dipped a toe into the savory pool, adding an herb or two; others embraced the idea full-on. The boldest new kid on the block is Kind's new Strong & Kind Roasted Jalapeno Bar. The seriously spicy bar is downright mouthwatering, and with 10 g of almond-powered protein, it's a perfectly executed sweet-to-savory snack transformation. ($2 per bar; kindsnacks.com)

5. Salt's da Bomb!
Savory's in, and sales of salty snacks have shot up 28 percent since 2008. But shoppers are concerned about getting too much salt: Label readers check sodium more than any other nutrition fact. We hear you, shoppers. We stock our Prevention chip drawer with snacks that satisfy with less than 110 mg of sodium per serving, like these.

6. What's Poppin'
Popcorn's become a force in the eat-clean world: It's light and minimalist and can actually be good for you. Sales have popped 16 percent from 2008 to 2013, and more popcorn innovations happen in the United States than anywhere else. Is popcorn the perfect snack? Seems so, thanks to healthy takes like these.

9. Meet Maple Water
Water. The most elemental drink we humans know. Can ambitious, show-us-anything-and-we'll-make-it-healthier packaged-food companies improve on it? Of course they can. This is the era of "naturally functional foods"--2014's single biggest trend, according to New Nutrition Business--when whole foods are packaged in convenient, nothing-added forms. This year we're tapping maple water, the springtime sap straight from maple trees. (Now, that's natural.)

Happy Tree Maple Water ($4; drinkhappytree.com or Whole Foods). Prevention Health Director Kate Lowenstein says to drink it really cold to taste the subtle maple flavor even more.

10. Flavor Amnesty Now
The ethnic-food sector is expected to grow more than 20 percent over the next 3 years, and shoppers--4 in 10, finds a Mintel report on the topic--are asking for more options in the freezer aisle. Finding lower-sodium gems is tough, but we're putting these new flavors on ice.

11. YOWZA!
Have a glass of water at the ready...This year, peppers topped McCormick's Flavor Forecast report (the spice company's annual list of predictions), proving that products from crackers to condiments really are getting much spicier. Even the trendy chipotle is mild by this year's standards: Tongue-burning peppers like the aji amarillo and habanero are taking its place in snacks both sweet and savory. In the spirit of feverish flavor, these foods set our hearts and taste buds aflame.
