NEW YORK (TheStreet) -- "The natural and organic trend is alive and well," TheStreet's Jack Mohr said following a slew of earnings results from some of the top players in the industry. 

Most recently, WhiteWave Foods (WWAV) , the maker of natural and organic milk and plant-based milk products such as soy milk and almond milk, reported a revenue and EPS beat for the third quarter.

This follows up strong reports from Hain Celestial Group (HAIN) - Get Report , which is trading at an all-time high, and Whole Foods Market (WFM) , which rallied some 20% following its fiscal fourth quarter results. The stock has declined severely over the past several quarters, as investors worried about margin pressures and comp-store sales growth. 

Part of that margin pressure can be explained though, as Kroger (KR) - Get Report has significantly upped its game in the natural and organic food space, Mohr explained.

Kroger, the second largest supermarket chain in the U.S., recognized this shift to healthier eating and beat most of its peers to the market. The company even introduced its own brand, Simple Truth, which now has more than 400 items. 

Mohr says half of the company's in-store customers will buy natural and organic product. Management expanded on that note, saying they believe natural and organic sales could double in "a relatively short amount of time." 

Kroger has beat on top and bottom line estimates in each of the past three quarters, the latest of which came in September, when the company posted 11.4% revenue growth from the previous year. The stock also pays a 1.3% dividend yield. 

"Kroger is a unique, under-appreciated way to play the healthy and living trend," Mohr concluded.
