Scientists from Wageningen University conducted studies to evaluate the use of mealworms as a sustainable protein for human consumption. They found the energy consumption during mealworm production is lower than beef, similar to pork, but higher than the energy used in chicken and milk production. The mealworms also require less land and emit less greenhouse gases than the production of milk, chicken, pork or beef. Animators from NMA News animated the research study. The taste of mealworms as food is still questionable.
