Why bother with cricket protein?

We are reviewing key protein powder ingredients and looking at crickets in this blog.

Cricket protein is new to the market with Protein Rebel creating the first (maybe) sport nutrition powder using crickets in the UK. Given the lack of awareness of this superfood why go to the bother of using crickets? Quite simply we believe they are a protein of the future.

What crickets can do for you…

Crickets are eaten as part of the everyday diet in south east Asia. If you have been on holiday in Thailand, you are likely to have seen a variety of insects sold as street food. The key cricket species used for human consumption is the house cricket (Acheta domesticus). Originally from south east Asia, they are now farmed for commercial food consumption in North America and Europe.

To suit Western tastes and improve convenience, most crickets are processed to turn them into cricket flour. This fine powder is then added to foods to increase the nutritional content as they are a great superfood supplement.

What makes them a superfood?

Superfoods are defined by the Oxford English Dictionary as, “a nutrient-rich food considered to be especially beneficial for health and well-being.” Crickets are right up there with kale, goji berries and turmeric. They maybe small but they pack a powerful nutritional punch as they are:

Rich in protein and essential amino acids. Crickets naturally have between 65% to 69% content of complete protein, meaning they contain all the essential amino acids that the body cannot produce. This means crickets have a protein content higher than chicken, beef, pork or salmon.

Table 1: Protein content in food compared

Food % Protein content
Chicken breast (grilled without skin) 32
Beef steak (lean grilled) 31
Lamb chop (lean grilled) 29.2
Pork chop (lean grilled) 31.6
Salmon (grilled) 24.2
Whole milk 3.3
Cricket 65-69


High in Iron: This is split into haem iron and non-haem iron. Haem iron is only present in animals (including insects) and is more easily absorbed than non-haem iron. You want that one. What’s more crickets have 168mg of iron per 100g which is more than spinach (3.6mg per 100g). Watch out Popeye!

Vit B12: this is an important vitamin than can be hard to find as it is only produced in animal products. Crickets are stacked full of Vitamin B12 with 23μg per 100g which is with more than beef (6.2μg per 100g).

Antioxidant activity: This is the measurement of free radicals scavenging ability to prevent, protect or delay against oxidisation in other compounds. Researchers have found that crickets have 5 times as much antioxidant capacity as orange juice. Good stuff!

Prebiotic: this is different from probiotic and not a spelling mistake. Prebiotic is food for the good bugs in your gut. Our modern lifestyles see us consume too much food (e.g. take away, alcohol, fast food) for the bad bugs in our gut which outgrow the good bugs. This can then cause stomach discomfort, bloating and other issues. Crickets are full of prebiotic fibre which helps your good bugs grow. Well done crickets!

Trace vitamins and minerals: these are vital components for metabolizes nutrients, maintaining your immune system, growing and repairing body tissue as well as ensuring general connectivity between cells. Insects have been found to be good sources of many of these particularly zinc, copper, magnesium and manganese.

*Cricket Powder BCAA’s is based on analysis of those used in our products

High in BCAA: as well as being high in protein, crickets have a high level of Branch Chain Amino Acids (BCAA). These are the building blocks of protein and are classed as being essential. This means we cannot produce them in our bodies and need to adsorb them through our food. BCAA are highly regarded as they have been identified as the key amino acids which support the rebuilding and strengthening of muscle fibres after exercise. The chart below shows they are second only to whey in BCAA content but without the stomach issues associated with whey. Win, win!

Whilst you might think it is just their nutritional qualities that make them a superfood, their sustainability credentials are like no other. They have a very low environmental footprint and beat other animal protein sources hands down.

Planet impact

The United Nations says the use of insect protein, such as cricket flour, could be critical in feeding the growing population of the planet while being less damaging to the environment. Why do they say that?

Less land, water, feed and greenhouse gases

To produce 1kg of protein using cricket compared to beef, chicken and pork requires much less of everything:

  Cattle Pig Chicken Crickets
Land (m2) 250 55 45 15
Water (litres) 30,000 3,500 2,300 1
Feed (kg) 40 7 2.5 1.7
Greenhouse gases (g) 2,850 1,130 300 1

And that’s because the food conversion efficiency of crickets is 15 to 20 times higher than beef cattle.

So, when you look at all the evidence there is a lot to love. They are good for you and good for the planet. But what about the taste? Crickets are described as having a mild and nutty taste that easily carries flavours. This means you can mix them with anything and they will taste great. That is exactly what we have done.
