Insects As a Complete Nutritional Source

For most animals insects are used as part of a diet, but strict insectivores only consume insects and other invertebrates. For them, all nutrients need to be available in suitable proportions to prevent nutritional deficiencies. Common deficiencies pertain to the vitamins A and D, and the mineral calcium. Moreover, concentrations of taurine, thiamine, vitamin E, omega-3 fatty acids are seemingly lower in most cultured insects than in wild insects. Mitigation strategies to prevent deficiencies are described, and future studies to further tailor insect composition towards nutrient requirements are suggested.
