From packaging to shopping to the flavors themselves, here’s what to look for in terms of nutrition in 2018.

On Nutrition

In many respects, the world of nutrition doesn’t change as much as some headlines would have you believe. Vegetables have always been good for you, and there are very, very few paradigm shifts of the “everything you thought you knew about nutrition is wrong” sort. Very few. That said, here are six interesting shifts that may change how you shop and eat in 2018:

Blockchains. Want more transparency about where your food comes from? You may be getting it soon. Blockchain technology is used in some nonfood industries to track every transaction, improving efficiency and security. The food industry — both in the U.S. and globally — is starting to adopt the technology as well. This will allow food to be tracked along the whole supply chain — farmers, packers, distributors, processors, grocers, restaurants and exporters. One big upside from this is likely to be food safety — foodborne illness outbreaks could be traced back to the source more quickly with blockchain practices.

Minimalist packaging. Isn’t it amazing how much stuff can be crammed onto a food label? You often have to wade through a lot of health claims, certification stamps and what amounts to a lot of advertising and marketing in order to find the really useful information: the Nutrition Facts Panel and the ingredient list. Fortunately, a growing move toward minimalist packaging may make your trips to the grocery store less confusing.

Food waste. Food waste is a big problem in America, with as much as 40 percent of food produced for human consumption never making it to a human stomach. This isn’t good for the environment, the economy or people suffering from food insecurity. Look for more food startups to put otherwise unwanted foods — “ugly” produce, underappreciated types of seafood and spent grains from beer brewing — to use in new food products.
