Is it Safe to Eat Cicadas?
Expert Insights and Guidelines
For those adventurous eaters curious about unusual culinary experiences, the question arises: Is it safe to eat cicadas? Cicadas are indeed safe to eat, making them a unique and protein-rich addition to your diet. Experts suggest harvesting tenerals—cicadas that have just molted—since their exoskeletons are still soft.
Collecting and preparing cicadas can be an intriguing activity. To humanely kill them, freeze them overnight, followed by a thorough wash to remove any dirt. If dealing with adult cicadas, removing the wings is recommended, similar to how shrimp are peeled.
Given that the FDA advises those with shellfish allergies to avoid cicadas due to potential cross-reactivity, it's essential to consider personal health conditions before indulging. Despite this, for the majority, integrating cicadas into meals can introduce a novel and nutritionally beneficial element to the diet.
Cicada Basics
Cicadas are fascinating insects known for their unique life cycles and loud, distinctive calls. They undergo several life stages and are classified into two main groups: periodical and annual cicadas.
Life Stages
Cicadas experience three main life stages: egg, nymph, and adult. Eggs are laid in tree branches, where they hatch into nymphs. Nymphs then drop to the ground and burrow underground. They stay underground for several years, feeding on tree roots.
Once mature, nymphs emerge and molt into winged adults. This transformation from nymph to adult is called molting. The teneral stage follows immediately after molting. In this stage, their exoskeleton is still soft and pale. As adults, cicadas live above ground for about four to six weeks.
Periodical vs. Annual Cicadas
Periodical cicadas, such as those in Brood X, emerge in large numbers every 13 or 17 years. These cicadas spent most of their lives underground, emerging simultaneously in massive broods. This synchronized emergence overwhelms predators, ensuring the survival of many individuals.
Annual cicadas, on the other hand, have life cycles that last between two to five years. They do not emerge in synchronized broods but are seen every year. This makes them less conspicuous compared to their periodical counterparts. The consistent appearance of annual cicadas contributes to a stable, though smaller, population above ground each year.
Understanding these differences helps in appreciating the unique biological phenomena that cicadas represent.
Nutritional Profile
Cicadas offer a rich source of protein and are packed with essential vitamins and minerals. This makes them a valuable food option for those interested in edible insects.
Protein Content
Cicadas are renowned for their high protein content. They provide a complete source of essential amino acids, which are crucial for body functions such as tissue repair and immune response. In fact, cicadas can contain up to 30-40% protein by weight, making them comparable to more traditional protein sources like chicken and beef.
Protein Quality: The proteins in cicadas are considered high-quality, containing all nine essential amino acids that the human body cannot synthesize. This can be particularly beneficial for athletes and those looking to maintain or gain muscle mass.
Vitamins and Minerals
In addition to protein, cicadas are also rich in various vitamins and minerals. Notably, they contain high levels of B vitamins, including B12, which is important for nerve function and the production of red blood cells.
Minerals such as iron, magnesium, and zinc are also present in appreciable amounts. Iron is crucial for transporting oxygen in the blood, while magnesium plays a role in muscle and nerve functions. Zinc is essential for immune health and wound healing.
These nutrients contribute to the overall health benefits of cicadas, making them a nutritionally dense food choice.
