While ground-up insects contain a “highly nutritious” mixture of amino acids, minerals, and micronutrients, long-term studies are lacking on the health effects of replacing meat and dairy with insects, the article states, enumerating several issues.

Many if not most humans may be unable to digest the chitin in insect exoskeletons. It may interfere with the absorption of dietary fats and might over the long term cause deficiencies in fat-soluble vitamins A and E.

Chitin activates the immune system in various ways, and “the significance of chitin and its derivatives on immune responses has not been fully appreciated.” Persons who are allergic to shellfish may be allergic to chitin as well.
