‡ - Patterns of mineral requirement for adults and children four or more years of age based on a 2000 kcal (8368 kJ) intake; RDI - Reference daily intake in 101.9 (c) (8) iv. FDA (2010). %RDI met is the ratio of the individual mineral element to the recommended RDI by FDA calculated as; (estimated mineral content × 100)/RDI of FDA. Values in the parenthesis are the percent increase estimated for fatty acids of fermented kernels over the raw kernels
