Resistant starch (RS) shows potential health benefits against certain metabolic diseases, hence, this research was aimed to determine the resistant starch contents of certain traditional foods using the Megazyme resistant starch assay kit (Megazyme, Bray, Ireland). The experimental sample was divided into four groups (cereals, legumes, stem tubers and root tubers). The RS contents measured from the pellet left after 16hr of α-amylase and amyloglucosidase digestion of samples, were greater than 10% for all the samples analyzed. White yam had the highest total starch (TS) (103.37 ± 23.43 %w/w), followed by maize (88.34 ± 8.51) and Eddoe (87.27 ± 2.32) and the least was Bambara nut (54.54 ± 2.33). Among the various groups, legume showed the least TS content on average. The resistant starch contents in the legume samples analyzed ranged from 31.60 ± 4.12 to 41.94 ± 0.43 (%w/w). On the other hand, the NRS contents in legume samples ranged from 17.30 ± 8.50 to 28.54 ± 7.57. Among the legumes analyzed, Pigeon pea had the highest RS content of 41.94 ± 0.43 and lowest NRS content of 17.30 ± 8.51. Bambara nut had quite low NRS of 17.19 ± 4.57 and relatively moderate RS content of 37.35 ± 2.93. The resistant starch contents in cereals ranged from 25.07 ± 4.19 to 31.59 ± 4.83 (%w/w). This result showed that among the various groups, cereals had the lowest RS but had the highest NRS contents on average. The NRS contents in cereals ranged from 30.12 ± 8.45 to 56.67 ± 7.51. There was a significant decrease, p<0.05, in the RS content of bitter yam (25.82 ± 10.81) when compared to all the other tubers. Conversely, there was a significant increase, p<0.05, in the level of RS content of Eddoe (54.85 ± 5.02) when compared to the bitter yam and Taro. White yam with 51.40 ± 18.29, was significantly high, p<0.05, in NRS content when compared to the other tubers. Among the stem tubers, the RS content of water yam, white yam and bitter yam was 44.69±3.95, 52.25 ± 16.96 and 25.82 ± 10.81 res
