¹Values are mean ± SEM. Statistical analysis by an unpaired t test (data normally distributed) or a nonparametric Mann–Whitney U test (data not normally distributed) with AN n = 32, RA n = 21 samples. AN, Alaska Native; RA, rural African.

²Includes resistant starch + 10% carbohydrates, which is predominantly resistant starch in the cooked African cornmeal diet [as described before (10)].
