Another study has confirmed the positive properties concerning nuts. The new research, published on Nutrients and conducted by a group of researchers from the Center for Molecular Oncology of the University of Connecticut, emphasizes in particular the positive effects of walnuts on ulcerative colitis.
Ulcerative colitis is an inflammatory bowel disease that sees chronic inflammation of the gastrointestinal tract. The two researchers Daniel Rosenberg Masako Nakanishi conducted some experiments on rodents and found that in a particular model of colitis, one in which there is a lesion of the colonic mucosa caused by the ulcerogenic dextran sodium sulfate agent, the nuts themselves could perform a real action of contrast.
Rodents were given a daily amount of nuts representing 14% of the entire daily diet, an amount equivalent to about 20-25 walnuts for a human being. After two weeks of this treatment, the researchers noticed fewer lesions and generally a repair of the colonic mucosa.
In general, the researchers also noted that the intestinal lesions in mice that ate these amounts of nuts were smaller than in mice that did not eat nuts (both groups had been experimentally induced by ulcerative colitis). They also noted some alterations in fecal and tissue flow as well as various changes in metabolites.
As Rosenberg himself specifies with this research, his team does not intend to suggest that it is necessary to eat 25 nuts a day to counteract ulcerative colitis but still want to find out what those phytochemical active compounds are that in nuts activate this sort of protection of the gastrointestinal tract.
