Resumo(s)
The increased interest in functional foods has driven research into health-promoting properties. This study evaluated muffins made with 100 % oatmeal (OM) or a 50:50 lentil/oatmeal flour mix (LM) using the INFOGEST in vitro model. Analysis included starch composition, glycaemic response, cytotoxicity, and immunomodulatory effects in Caco-2 cells under basal and stimulated conditions. Digestion revealed limited hydrolysis in oral/gastric phases, with increase in intestinal phase. OM exhibited 8.9 % higher starch and greater hydrolysis. In contrast, LM presented 9.3 % lower estimated glycaemic index. Both muffins were non-toxic. Under stimulation, LM showed stronger anti-inflammatory effects, decreasing interleukin-6/8 mRNA and cytokine levels, while upregulating Transforming Growth Factor-β under basal conditions. LM enhanced barrier integrity, reduced Acetyl-Coenzyme A acetyltransferase 2 , and upregulated Peroxisome proliferator-activated receptor-γ and Sirtuin 1 , indicating improved metabolic regulation. These findings highlight lentil/oatmeal muffins as functional options that may support glycaemic control and intestinal health, aiding strategies against diabetes and cardiovascular disease.
