The discrepancy may be due to the fact that 100g of the beans will have more water in them when raw or cooked .. But when roasted and dried, they will lose the water weight. 100 grams of dried, roasted beans probably weighed 2 or 3 times as much when in their moist state.

Thus, 100g of dried, roasted beans could have 2 - 3 times the nutrient count as for raw or canned/boiled.
