Consumption of plant food rich meals, such as feijoada, a traditional meal in Brazil, is associated with the reduction of chronic disease. The objectives of this study were to determine phytochemical content, antioxidant activity by chemical and cellular antioxidant assay (CAA), of feijoada with or without in vitro digestion. Feijoada showed no difference for phenolics and flavonoids after digestion. Bound and residue contributions to total phenolics were 20.9% and 32.2%, respectively, suggesting that phenolics reach colon after intake. Flavonoids in residue and bound fractions represented 50% of total flavonoids. Antioxidant activity of feijoada without digestion was higher than with digestion, however, it showed lower antiproliferative activity and CAA. Feijoada with in vitro digestion also yielded phenolics with higher CAA. Analyses of whole meals should be used to evaluate phytochemicals present in food mixtures consumed, especially with digestion models coupled with CAA resulting in similar information to those in physiological conditions.
