Montmorency tart cherries may play a role in improving gut health, according to a small human trial of nine adults combined with a parallel laboratory study published in the\u00a0Journal of Nutritional Biochemistry<\/a>.\u00a0An international team of scientists found that\u00a0Montmorency\u00a0tart cherries helped to positively impact the gut microbiome, a collection of trillions of bacteria and other microbes that live in the intestinal tract.<\/p>\n

The microbiome has been the focus of multiple studies in recent years due to its potential role in maintaining digestive health, as well as its impact on immunity, heart health, blood sugar control, weight management, and even brain health. The gut microbiome holds great promise, especially related to personalized nutrition, although the research is still evolving and larger, long-term human intervention studies are needed.\u00a0However, the new study does suggest that\u00a0Montmorency\u00a0tart cherries can be added to the list of gut-friendly foods.<\/p>\n

While previous studies on\u00a0Montmorency\u00a0tart cherries have ranged from heart health and exercise recovery to sleep, this is the first study to explore the potential gut health benefits. The researchers speculated that it may be due to the polyphenols (anthocyanins and other flavonoids) in\u00a0Montmorency tart cherries, the varietal of tart cherries grown in the U.S.\u00a0Polyphenols in plant-based foods are broken down by microbes to stimulate growth of good bacteria.<\/p>\n

“Montmorency\u00a0tart cherries were a logical food to study due to their unique composition of polyphenols, including chlorogenic acids,” said principal investigator Franck Carbonero, PhD, assistant professor in the Department of Food Science at the\u00a0University of Arkansas. “Our results suggest that the unique polyphenol mixture in tart cherries may help positively shape the gut microbiome, which could potentially have far-reaching health implications.”<\/p>\n

Research Methodology
\n<\/strong><\/span>Researchers conducted both human and laboratory experiments to determine the impact of\u00a0Montmorency\u00a0tart cherries on the microbiome. In the human trial, nine healthy adults, 23-30 years old, drank 8 ounces of\u00a0Montmorency\u00a0tart cherry juice (from concentrate) daily for five days. These individuals were non-smokers and had not taken antibiotics (which can affect the microbiome) in the 12 weeks prior and during the study. Using stool samples, the participants’ microbiome was analyzed before and after the dietary intervention, and food frequency questionnaires were used to evaluate their overall diet.<\/p>\n

The laboratory experiments were set up to mimic the conditions within the human digestive system, specifically the stomach, small intestine and three regions of the colon, to study how polyphenols are broken down and absorbed. This process of breakdown and absorption can have a significant impact on the body’s ability to use the beneficial bioactive compounds in plant-based foods. The researchers tested U.S.-grown\u00a0Montmorency\u00a0tart cherries, European tart cherries, sweet cherries, apricots and isolated polyphenols in each simulated region of the digestive tract. They analyzed changes in the mix of bacteria and how these bacteria helped digest the polyphenols over time.<\/p>\n

Study Results
\n<\/strong><\/span>In the human trial, the microbiome was positively altered (primarily measured by the increase in good bacteria) after just five days of drinking\u00a0Montmorency\u00a0tart cherry concentrate, although there were strikingly different responses due to the participants’ initial microbiome composition. Individuals who ate a more Western diet (low in fruits, vegetables and fiber) potentially had a lower ability to metabolize polyphenols, thereby reducing bioavailability and any potential health benefits in the tart cherries. Remarkably, in these subjects, instead of\u00a0Bifidobacterium,\u00a0Collinsella\u00a0were the beneficial polyphenol-degrading bacteria stimulated. The individuals who ate a more plant-based diet, with higher intakes of carbohydrates and fiber, responded with an increase in\u00a0Bacteroides\u00a0and\u00a0Bifidobacterium,\u00a0presumably because of the specific combination of polysaccharides and polyphenols.<\/p>\n

While more research is needed, these results suggest individuals consuming a more plant-based diet may have a mix of gut bacteria that responds more positively and\/or rapidly to tart cherry consumption. Individuals consuming a more Western diet that is lower in carbohydrates and fiber may have a lower\/different ability to metabolize polyphenols, thereby altering bioavailability and any potential health benefits.<\/p>\n

The laboratory experiments found that pure polyphenols characteristics of tart cherries increased the amount of\u00a0Bifidobacterium. However, when concentrated juices were fermented, this bifidogenic effect appeared to be leveled out by the larger increase of polysaccharides utilizing bacteria. Somewhat surprisingly, Carbonero said, chemistry analyses showed that tart cherries polyphenols were not completely converted to smaller phenolic metabolites, suggesting that the full diversity of bacterial species in the human gut is required for efficient breakdown of the polyphenols in tart cherries.<\/p>\n

While the dietary intervention was based on a limited number of human volunteers and more research is needed to support these conclusions, the results help build the foundation for future research and suggest\u00a0Montmorency\u00a0tart cherries can play a role in positively shaping the microbiome and maintaining gut health.<\/p>\n

Montmorency\u00a0tart cherries are the most common variety of tart cherries grown in the U.S., and are available year-round in dried, frozen, canned, and juice forms – including juice concentrate, which was the form used in this human trial.\u00a0Montmorency\u00a0tart cherry juice concentrate can be mixed with water or other juices. It can also be consumed straight from the bottle or used as an ingredient in recipes, such as smoothies and other beverages.<\/p>\n
