25% of people have nonalcoholic fatty liver disease (2019 study)

They should eat beans.

Nonalcoholic fatty liver disease (NAFLD) affects 25% of the global adult population with a range of 13.5% in Africa and 31.8% in the Middle East.

Probably from loss of gut bacteria "Akkermansia muciniphila"

increasing evidence suggests a role of intestinal dysbiosis in obesity and non-alcoholic fatty liver disease
these results indicate the role of intestinal dysbiosis in the development of NAFLD associated with obesity. There was a differential microbiota profile between obese patients, with and without NAFLD. Thus, supporting gut microbiota modulation as a therapeutic alternative for the prevention and treatment of NAFLD.

These results indicate that A. muciniphila prevents fatty liver disease in obese mice by regulating triglyceride synthesis in the liver and maintaining gut homeostasis.

Our results suggested that A. muciniphila had beneficial effects on immune-mediated liver injury by alleviating inflammation and hepatocellular death. These effects may be driven by the protective profile of the intestinal community induced by the bacteria. The results provide a new perspective on the immune function of gut microbiota in host diseases.

Fiber‐rich dietary pulses, such as common beans (Phaseolus vulgaris) have the potential to modify the colonic microenvironment (microbiota and host epithelial barrier) which can mitigate the severity of gut‐associated pathologies. Obesity is associated with impairments in the mucosal barrier (leaky gut) and specific changes in the abundance of bacteria communities within the gut microbiota.
Specifically, fecal abundance of Akkermansia muciniphila, whose abundance is inversely related to the severity of the obese phenotype, was increased in the HF+B(high fat + beans) group versus HF by 20‐fold, which was associated with a reduction in visceral adipose mRNA expression of the inflammatory mediators MCP‐1 and IL‐6 and increased expression of adiponectin. Colon epithelial barrier integrity was improved in the HF+B group versus HF, Additionally, evidence of an enhanced mucus barrier and anti‐microbial defense was apparent in the HF+B group versus HF. In conclusion, bean supplementation enhanced gut barrier integrity and exerted a beneficial colon‐function priming effect that helps mitigate the severity of the obese phenotype.
