When discussions about eating locusts arise, emotion often dominates the conversation. But when the comparison is reduced to data alone, locusts present a compelling case as a protein source.
From a nutritional perspective, locusts are exceptionally dense. Dried locusts contain 72% complete protein, including all nine essential amino acids. By comparison, beef contains roughly 26% protein by dry weight. Locusts are also naturally rich in vitamin B12, iron, zinc, magnesium, and essential fatty acids such as omega-3 and omega-6.
Locusts vs. Red Meat: What the Numbers Actually Look Like
When people talk about alternative proteins, the conversation often jumps straight to emotion, curiosity, or discomfort. But if we slow things down and look at the numbers, the comparison becomes surprisingly straightforward.
An average adult needs about 0.8 grams of protein per kilogram of body weight per day. For a 70-kg person, that adds up to roughly 20 kilograms of protein per year.
So how do different protein sources measure up?
Beef contains about 26 grams of protein per 100 grams. To meet annual protein needs through red meat alone, a person would need close to 80 kilograms of beef per year. That’s before accounting for cooking loss, trimming, and waste.
Dried edible locusts, on the other hand, contain 72% protein by weight. Using a conservative estimate, meeting the same annual protein requirement would take only 28 kilograms of dried locusts per year.
In simple terms, locusts deliver the same amount of protein with significantly less food volume. Almost three times less food volume vs. beef and even more than that vs. chicken or soy.
Another way to look at it is daily intake. To meet protein needs, a person would consume roughly 220 grams of beef per day, or about 77 grams of locusts per day. Different forms, same nutritional outcome.
The difference becomes even clearer when looking at efficiency. Cattle convert only a small fraction of their feed into body mass (1:20), while insects like locusts convert a much higher percentage of what they eat into body mass (1:1.3). This means far less feed is required per gram of usable protein – ninety times less feed!
What these numbers show is not that locusts must replace red meat overnight, but that they are nutritionally capable of doing the job. They are not a novelty protein or a symbolic gesture. On a purely practical level, locusts can deliver complete, high-quality protein in a far more concentrated and efficient form.
As food systems face growing pressure to feed more people with fewer resources, these kinds of comparisons matter. Not because they force a choice, but because they expand what is realistically possible.
