Resumen

© 2018, © 2018 American College of Nutrition. Objective: Colon cancer occupies the third place in incidence worldwide; eating habits, in particular, consumption of hypercaloric diets, are relevant in its etiopathogenesis. On the other hand, foods can also modulate carcinogenesis: for example, proteins, which when hydrolyzed release peptides with biological activities, and legumes, especially, chickpea, represent a good source of hydrolysates. The objective of this work was to verify the inhibitory effect of chickpea hydrolyzed protein on azoxymethane (AOM)-induced carcinogenesis in mice fed a hypercaloric diet. Methods: We hydrolyzed chickpea protein by pepsin, pancreatin, and a combined pepsin–pancreatin system, to test its anticarcinogenic and hypercaloric activity in mice that had consumed a hypercaloric diet or a normal diet but were injected with azoxymethane (AOM). Results: A concentrate (70% proteins) was obtained from chickpea seeds (18.5% proteins), and extensive hydrolysates were obtained at 15 minutes, in all tested enzyme systems. The greatest activity was evidenced in the hydrolysates obtained with pepsin–pancreatin at 90 minutes. Animals that consumed the hypercaloric diet had a higher concentration of cholesterol and a higher atherogenic index, which were significantly reduced with the administration of chickpea protein hydrolysates with a dose-response effect (10, 20, or 30 mg/kg), whereas no effect was observed in animals that consumed the normal diet. In animals given AOM, aberrant crypts were observed, at a higher rate in animals that consumed the hypercaloric diet; with the consumption of hydrolysates by the animals that consumed either diet, the number of aberrant crypts was reduced with the 3 doses tested, and the effect was better in those animals fed the hypercaloric diet. The best effect in all tests was with 30 mg/kg body weight. Conclusion: The consumption of chickpea protein hydrolysates might confer a protective effect against colon carcinogenesis.
