Concentration is what separates this entry from its family: drying, grinding, and juicing pack the oxalate of the whole food into a smaller serving, so concentrated forms usually measure higher than fresh ones of the same base. Sesame seeds seeds sits at 41 mg per serving, in the middle of the family range. Where a recipe allows the fresh form it is generally the lighter pick; where only the concentrated form works, portion size is the lever that keeps the daily budget intact. Related forms in this family: Hemp seed seeds (11 mg), Flaxseed seeds (72 mg), Sunflower seed kernels seeds (6 mg).
