on the basis of our results and a review of the findings of other investigators , we argue that there is no evidence that tannins reduce the nutritional value of an insect 's food by inhibiting digestive enzymes or by reducing the digestibility of ingested proteins and , further , that the failure of tannins to interfere with digestion is readily explained on the basis of well-documented characteristics of the digestive systems of herbivorous insects .
