Crickets as a Powerhouse of Complete Protein
Crickets are a remarkably efficient source of protein, with a composition that rivals or even surpasses traditional sources like beef and chicken on a dry weight basis. More importantly, cricket protein is considered 'complete,' meaning it contains all nine of the essential amino acids that the human body cannot produce on its own. This makes them a high-quality protein comparable to meat, eggs, and dairy, unlike many plant-based proteins which are often incomplete and must be combined to form a full amino acid profile. The rich amino acid content is a key factor in their growing popularity within the health food market.
The Amino Acid Profile of Cricket Protein
The amino acid composition of cricket protein includes high levels of key essential amino acids, including Branch Chain Amino Acids (BCAAs) like leucine, isoleucine, and valine. These are particularly important for muscle protein synthesis and recovery after exercise. While the exact profile can vary slightly based on the cricket species, its diet, and its stage of development, research consistently shows a robust and balanced supply of essential amino acids. In some comparisons, the amino acid content of cricket powder is significantly higher than that of wheat flour.
More Than Just Protein: A Nutrient-Dense Profile
Beyond their impressive protein content, crickets offer a host of other beneficial nutrients that contribute to their 'superfood' status. These include healthy fats, vitamins, and minerals that are often lacking in many diets. The full nutritional picture shows why crickets are seen as a holistic food source.
Key nutrients found in crickets include:
- Minerals: Higher in iron than beef, more calcium than dairy, and packed with zinc, magnesium, copper, and manganese.
- Vitamins: An excellent source of B vitamins, including B12, riboflavin, biotin, and pantothenic acid.
- Healthy Fats: Crickets provide important polyunsaturated fatty acids, including a beneficial ratio of omega-3 and omega-6 fatty acids that support heart health.
- Dietary Fiber: Unlike most animal proteins, crickets contain fiber in the form of chitin, their exoskeleton.
Understanding Chitin: The Fiber in Cricket Protein
Chitin, a complex carbohydrate found in the cricket exoskeleton, is a form of insoluble dietary fiber. The presence of chitin is one of the main factors influencing the digestibility of cricket protein. While whole crickets or less-processed flour may have lower digestibility than certain refined proteins, removing the exoskeleton significantly improves the protein's bioavailability. However, leaving the chitin intact offers its own health benefits. Chitin acts as a prebiotic, feeding beneficial bacteria in the gut and promoting a healthy microbiome. Research has shown consuming cricket powder can increase beneficial gut bacteria and reduce inflammatory markers. Some processors remove the exoskeleton to create a more refined, higher-purity protein concentrate, but most cricket flour includes the valuable chitin fiber.
Cricket Flour (Acheta Powder) vs. Other Proteins
Processing crickets into a fine powder, often called cricket flour or acheta powder, increases the protein concentration by weight. This makes it an ideal ingredient for boosting the protein content in a variety of foods, from baked goods to protein bars and smoothies. The following table compares cricket flour to other popular protein sources.
| Source | Protein Content (dry weight) | Complete Protein | Environmental Impact (low/high) | Notable Extra Nutrients |
|---|---|---|---|---|
| Cricket Flour | ~60-70% | Yes | Low (less land, water, feed) | Fiber (chitin), Iron, B12 |
| Whey Protein | >90% (isolate) | Yes | Moderate (dairy industry) | BCAAs |
| Beef | ~50% (dry weight) | Yes | High (water, feed, GHG) | Iron, Zinc |
| Chicken | ~31% (dry weight) | Yes | Moderate (feed, GHG) | Niacin, B6 |
| Salmon | ~20% (dry weight) | Yes | High (feed, pollution) | Omega-3s, Vitamin D |
| Pea Protein | ~75-80% (isolate) | No (limiting amino acids) | Very Low | Iron |
This comparison highlights cricket flour's efficiency. While whey protein may have a higher concentration of protein in isolated form, cricket flour's nutritional profile includes fiber and a more comprehensive mineral and vitamin spectrum compared to many common proteins.
The Rising Popularity of Acheta Protein
The increasing awareness of sustainability and the nutritional density of crickets have driven their rise as a novel food ingredient. Cricket powder, or acheta powder, is a versatile product that allows consumers to incorporate insect protein without consuming whole insects. It is used in protein bars, baked goods, smoothies, and other enriched foods. For athletes, the balanced amino acid profile and high BCAA content make it an attractive alternative to traditional sports nutrition supplements like whey.
This sustainable approach to protein production is supported by organizations like the FAO, recognizing insects as a viable way to address future food security challenges. A growing number of companies, from startups to larger food manufacturers, are now using acheta powder as a key ingredient, with European and Canadian regulations progressing to authorize its use. The market continues to grow as the nutritional and environmental benefits become more widely known.
The Potential Health Benefits of Consuming Cricket Protein
Beyond basic nutrition, consuming cricket protein may offer several health advantages. The combination of protein, healthy fats, fiber, and micronutrients creates a powerful package. From supporting gut health to providing essential vitamins, crickets offer a holistic approach to nutrition.
Potential benefits include:
- Gut Health Improvement: The chitin fiber acts as a prebiotic, fostering the growth of beneficial gut bacteria.
- Reduced Inflammation: Some studies have linked cricket consumption to a decrease in TNF-α, a protein associated with inflammation.
- Improved Nutrient Absorption: Research suggests that minerals like iron may be more bioavailable from crickets than from beef.

Conclusion: The Versatile and Sustainable Protein Source
To summarize, what protein have crickets in it is a complete protein, fortified with all nine essential amino acids, and backed by a rich profile of minerals, vitamins, and healthy fats. As a highly sustainable alternative to traditional animal agriculture, cricket-based products, such as acheta powder, provide a versatile and nutritious ingredient for a variety of foods. With a growing focus on environmental responsibility and innovative food sources, crickets are emerging as a leading contender in the future of human nutrition, offering a complete protein and a host of other health benefits.
