6 Foods You Will Be Eating In 2018

Mocktails are not a new concept, but these nonalcoholic beverages have come a long way from sticky-sweet Shirley Temples. As more people limit their alcohol consumption, companies such as Ocean Spray and Welch's have offered up juicy alternatives.

In the spring, Ocean Spray debuted its line of cocktail juice blends. These bottled juices include flavors such as cranberry peach bellini and cranberry sangria.

Clark Reinhard, Ocean Spray's vice president of global innovation, told CNBC that repeat purchases of the brands' mocktails are strong and he expects the line to become a $100 million business for the company.

The key to the success of this trend is flavor. Consumers want to mimic the sophistication of having a specialty cocktail, but without the hangover or extra calories. So brands and restaurants that adopt this trend will need to make sure their concoctions look good and taste good.

Improving digestive health is a huge trend heading into 2018. In the last year, a number of companies promoted apple cider vinegar tonics as homeopathic remedies and a cure-all for everything from acne to hangovers.

There are already a number of products on the market that are rich in probiotics and micro-organisms and aim to support digestive and immune health. Expect to see more of these gut-healthy food items next year.

Tempeh, miso and kimchi are also likely to be added to menus across the restaurant industry as more consumers become aware of their healthful benefits.

Low-carb is the new paleo diet. The keto diet, short for ketogenic, focuses on lowering the number of carbs you eat and increasing your good fat intake.

By depriving your body of carbohydrates, it will naturally produce "ketones" that break down fat. This can help with weight loss and overall health.

Meals that fit into this diet contain meat, leafy greens, nuts and seeds, berries and high-fat dairy products, such as butter and cheese. The diet strips out grains, sugar, fruit and starches, such as potatoes.

The diet, which was first created in the early 1920s to treat epilepsy, has resurfaced in the last year thanks to social media. People who have followed this diet and have experienced dramatic weight loss have posted about it online, spurring others to give the diet a shot.

Meal kits and restaurants have begun to offer plates that mimic this dietary trend, and that can be expected to continue in 2018.

It should be noted that the keto diet isn't for everyone and not all people have received the same results from this high-fat meal plan.

Mushrooms in your coffee? Yes, it's a thing. And expect to see it cropping up in other, unexpected places in the next year.

The fungi are a good source of antioxidants, vitamins and fiber. And they are adaptable. Mushrooms are packed with protein and can be used in baking and cooking as a bulking agent. Harris told CNBC that mushrooms could soon be used in food coloring, as well.

Customers can already purchase mushroom-infused products such as Four Sigmatic's coffee, cocoa and matcha blends. Time will tell if this trend will be picked up by the likes of Starbucks and Dunkin.

Edible flowers have long been a way to add a quirky and sophisticated garnish to a dish, but in 2018, these flavors will take center stage. While flavors such as elderflower have floated around in the international market, expect to see more flowery flavors in the new year.

Hibiscus, lavender, rose and elderflower, among others, are expected to blossom at grocery stores and restaurants. Whole Foods Market listed floral flavors in its top ten trends for 2018, noting that lattes, teas and bubbly drinks will be the most likely candidates for this flavor infusion.
