Passive smoking has become a major problem stemming from damage to the body from people involuntarily exposed to cigarette smoke. Concern with this group of people has led the scientific community to research alternatives that might be used to prevent the harm caused by secondhand smoke. Thus, the objective of the present study was to evaluate the deleterious effects of chronic passive smoking on the histomorphometry and histopathology of the duodenum of growing rats supplemented or not with functional prebiotic, probiotic and symbiotic foods. A total of 96 rats were distributed in a completely randomized design in a 2 x 4 factorial scheme. Animals were supplemented with functional foods and passively or not exposed to cigarette smoke for 180 days for one hour daily five days a week. At the end of the experimental period, samples of the initial duodenum were collected for histomorphometric evaluation and histopathological analysis. Animals exposed to secondhand smoke showed less development of duodenal villi and crypts, increased inflammatory profiles and degenerative changes. It was observed that supplementation with functional foods provided a mitigating effect of the toxic effects of exposure to passive smoking in all analyzed parameters. It is concluded that the use of prebiotic, probiotic and symbiotic in the diet of rats exposed to passive smoking may be a possible way to attenuate the toxic effects induced by secondhand smoke on the duodenal mucosa, and may serve as prevention of mucosal damage and development of Diseases caused by passive exposure to cigarette smoke.
