New research from Euromonitor International shows that foods and beverages that are organic, or are promoted as "free from" gluten, sugar, peanuts and other allergens or organic properties drove value sales in 2016.

Overall organic food and beverage sales in 2016 were up 6.8% to $36 billion.

"Growth in organic and free-from food sales has boomed in 2016 as consumers are reading labels more carefully than ever, seeking natural ingredients and looking for foods that represent a 'guilt-free' purchase," said Ewa Hudson, head of health and wellness at Euromonitor International, in a news release.

Free-from and organic foods and beverages are expected to hit sales of $833 billion by 2021, according the release.
