What is Cricket Flour & Why You Should Eat It

What is Cricket Flour & Why You Should Eat It

By Brian Stanton on Jul 08, 2019

Cricket flour, or cricket powder, is a mild-tasting protein powder made out of milled crickets. Cricket protein is nothing new. People have been eating insects for millennia. It was only recently, however, that cricket flour appeared on the menu. But cricket flour isn’t just about nutrition. It’s about sustainability too. That’s right. The planet needs cricket protein just as badly as humans do.

What Is Cricket Flour?


These crickets come from cricket farms. Compared to feedlots (for raising and slaughtering cows), cricket farms use less feed and generate less greenhouse gases per kilogram protein harvested. And thanks to large-scale cricket farming and distribution, you can have cricket-based food products delivered straight to your door.

But why eat crickets? Is cricket protein powder really that healthy, really that eco-friendly?

You might be surprised.

In fact, cricket protein is nothing new. People have been eating insects for millennia.

It was only recently, however, that cricket flour appeared on the menu, bringing a number of health benefits with it.

Benefits of Cricket Flour

Like a cricket, cricket powder is a great source of protein, vitamins, minerals, fiber, and fatty acids. But unlike a cricket, cricket flour looks nothing like an insect. Still, 100% cricket powder is basically a whole food. All nutrients are preserved.

Thus, many tropical cultures forage for insects daily. (It’s hard work.)

But if you’re reading this article, you don’t need to work for your crickets. Thanks to large-scale cricket farming and distribution, you can have cricket products delivered straight to your door. And for good reason.

The specific benefits of cricket flour include:

  1. Cricket flour is a complete protein

  2. Cricket flour is good for the planet

  3. Cricket flour is rich in minerals

  4. Cricket flour is a good source of fatty acids

  5. Cricket flour is high in B vitamins

  6. Cricket flour supports gut health

#1: A Cricket Flour is a Complete Protein

Amino acids are the building blocks of protein. They form nearly every tissue in your body.

Cricket protein is considered a “complete protein” because it contains all nine essential amino acids. These amino acids -- leucine, isoleucine, valine, methionine, tryptophan, threonine, lysine, histidine, and phenylalanine -- are considered “essential” because you must get them through diet. You can’t synthesize them.

Leucine, for instance, is a branched chain amino acid (BCAA) crucial for muscle growth. You won’t find much leucine in plant protein, but cricket protein is a fine source of BCAAs.  

Then there’s tryptophan, needed to make your sleep hormone (melatonin) and your happy chemical (serotonin). Did you know that collagen protein -- all the rage right now -- has negligible levels of tryptophan?

Nothing against collagen, just don’t count it as a complete protein source. You need a complete protein -- like cricket protein -- to meet your daily protein needs.

#2: Cricket Flour is Good For The Planet

Beef is a great source of bioavailable protein. Unfortunately, raising cows isn’t so great for the environment.

When cows fart, they produce tons of methane. Methane, by the way, is an extremely potent greenhouse gas, about 30x more potent than carbon dioxide. Not good for climate change.

Conventional herding practices also destroy soil quality, create runoff waste, use excessive resources, and contribute to the problem of antibiotic resistance. Livestock, amazingly enough, account for 50-80% of worldwide antibiotic usage.

That’s where crickets come in. Compared to livestock farming, cricket farming:

- Requires significantly less land

- Produces less greenhouse gas emissions

- Doesn’t use lots of antibiotics

- Uses less feed per volume of protein produced

To be clear, crickets won’t solve climate change, pollution, and the global resource problem. But they can be part of the solution.

You can be part of the solution too by enjoying crickets, cricket flour, and cricket bars. If enough people do it, it will make a difference.

#3: Cricket Flour is Rich In Minerals

When you eat cricket powder, you’re eating the entire cricket. Which means valuable minerals come along for the ride.

These minerals include zinc, copper, iodine, and manganese. Here’s why you want more of these minerals in your diet:

Zinc supports immunity, hormone production, and DNA health. Zinc deficiency often shows up as dry skin, slow wound healing, hair loss, and sex hormone deficiency.

Copper supports skin health, immune function, and iron absorption[*]. It’s often deficient in the modern diet. Copper deficiency mimics iron-deficiency anemia, and presents as low white blood cells.

Iodine is required to produce thyroid hormone, which regulates your metabolism. Low iodine manifests as hypothyroidism.

Manganese helps you form bone and metabolize protein. Many enzymes in your body are dependent on manganese. One called glutamine synthetase turns toxic ammonia into glutamine, a beneficial amino acid.

The takeaway is that cricket powder -- unlike other protein powders -- contains valuable minerals scarce in the modern diet.

#4: Cricket Flour is a Good Source Of Fatty Acids  

Fat is not to be feared. Fat builds your cell membranes, stores energy, and helps you absorb fat-soluble vitamins like A, D, and K.

After protein, fat is the second largest source of calories in cricket flour. These fats include monounsaturated fat, polyunsaturated fat, and saturated fat. All have specific roles in your body.

Wait. Isn’t saturated fat bad for your heart?

That’s the conventional wisdom. But the latest science has found no link between dietary saturated fat and heart disease.

In fact, saturated fat consumption was inversely correlated with stroke incidence in a large Japanese cohort.

So don’t fear the fat, and enjoy your crickets.

#5: Cricket Flour is High In B Vitamins

Most people know B vitamins are good for you. Less people know why.

Take B12, abundant in cricket powder. B12 is important. It teams up with folate to synthesize your DNA and produce your red blood cells.

Skimp on B12 and a wide range of symptoms can result: brain fog, anemia, depression -- the list is long.

Animals are the best dietary source of B12. One serving of cricket protein powder, for example, contains 80% of the RDA.

Along with B12, cricket protein is also an excellent source of vitamin B2 (riboflavin) and vitamin B7 (biotin). Riboflavin and biotin support skin health, which is important to most people.

#6: Cricket Flour Supports Gut Health

Chitin is a prebiotic -- a special kind of fiber that feeds beneficial bacteria (probiotics) in your gut. A cricket’s exoskeleton, you’ll want to know, is made -- in part -- of chitin.

Scientists, in fact, believe that chitin may drive some of the gut-related health benefits of cricket flour.

Researchers fed 20 participants two separate breakfasts: one containing cricket flour, the other not. To eliminate bias, both subjects and scientists were blind to the breakfast type.

What do crickets taste like? They're mild, so easy to hide. In this case, chocolate malt did the trick.

After two weeks, the scientists recorded a 5.7x increase of a beneficial microbe called bifidobacterium animalis in those eating cricket flour. Eating cricket powder, in other words, meant more good bacteria, making it an amazing gut health supplement

You’re probably thinking: that’s great, but what does one microbe prove about gut health?

Alone, not much. But the researchers measured something else: inflammation.

After the two weeks were up, cricket flour eaters had lower inflammation. (As measured by an inflammatory particle called TNF-α).

“These data suggest,” conclude the authors, “that eating crickets may improve gut health and reduce systemic inflammation.”

Systemic inflammation has been linked to every chronic disease: diabetes, heart disease, cancer, and Alzheimer’s. This is a really cool finding

Cricket Flour Nutrition

In terms of nutrition, cricket powder is similar to whole crickets. One serving (10 grams) of cricket flour contains:

  • 50 calories

  • 6 grams protein

  • 2.5 grams fat

  • Less than 1 gram carbohydrate (0 grams sugar)

  • 25% RDA riboflavin

  • 80% RDA vitamin B12

  • 20% RDA biotin

  • 15% RDA zinc

Generally, cricket powder is:

  • High in protein, with all 9 essential amino acids

  • High in B vitamins

  • A good source of fatty acids

  • Rich in minerals like copper, zinc, and manganese

  • Rich in chitin, a prebiotic fiber that may support gut health

Because it’s nutrient-dense and low-carb, cricket flour compliments both the paleo and keto diet. Also, high-quality cricket powders are generally gluten-free, and dairy-free.

Note, however, that those with shellfish allergies should be cautious with cricket flour. Believe it or not, crickets and crustaceans are closely related!

Put another way: eating crickets is like eating shrimp or lobsters. Odd-looking, but delicious!

What Does Cricket Flour Taste Like?

Cricket powder has a lightly malted flavor, with hints of raw cocoa. Nothing to overwhelm your taste buds.

Nothing to overwhelm your daily smoothie either.

Here’s an idea. Next time a friend visits, offer them a cricket protein smoothie. (Note: first make sure this friend doesn’t have a crustacean allergy and is generally okay with eating meat).

“How does it taste?”, you will ask.

It tastes good. What’s in it?

List a few ingredients, then mention the cricket powder. Casually.

They will be surprised, but probably in a good way. Congrats, you’ve just converted another person to crickets. Bottoms up!

How To Eat Cricket Flour

Time to get practical about bringing cricket powder into your life.

Smoothies are probably the best vessel. Just blend away and you’ll hardly notice it.

Alternatively, you can mix cricket flour into your coffee, tea, eggs, rice, soup, water, desserts -- whatever works. A mild, malty flavor -- you’ll find -- goes with almost anything.

How much cricket protein should you eat? Depends on your activity level, current protein intake, and a variety of other factors.

Cricket flour, by the way, contains 6 grams protein per serving to help you meet your daily protein requirements.

But as you learned, crickets are more than just protein. They’re stocked with fiber, fatty acids, and micronutrients too.

In other words, think of cricket flour as a nutrient-dense smoothie booster. Boost away.

A New Source Of Cricket Protein

People have been eating crickets for ages. They’re a staple of the ancestral diet.

Cricket flour is new, but just as nutritious -- packed with vitamins, minerals, protein, fatty acids, and prebiotic fiber.

Going cricket means going green. Compared to protein culled from conventional livestock, cricket protein is much more eco-friendly.

To be clear, cricket powder isn’t the only healthy protein out there. When you open your closet, there isn’t only one shirt that fits.

But there’s one shirt (picture it) that’s a little softer, a little more comfortable, a little -- well -- better than the others.

Maybe cricket flour will be like this shirt: Your new favorite. Only one way to find out.
