How Much Protein Is in Buckwheat?
Buckwheat has 3.4g of protein per 100g and 92 calories. Here is what that means per realistic portion, how it compares with similar foods, and how to use it to hit a daily protein target.
Protein in buckwheat
Buckwheat contains 3.4g of protein per 100g, alongside 92 calories. That works out to 3.7g of protein per 100 calories, which is a low protein density — this is not primarily a protein food.
Weigh what you actually eat: 100g is a reference amount, not a portion. Multiply 3.4g by your portion weight and divide by 100.
To reach 30g of protein from buckwheat alone you would need about 882g — which is why it works better as part of a meal than as the protein source

Protein Hunter is a protein and nutrition app with a database of 232 foods — from a leaf of kale to a wagyu steak — plus AI tools that answer protein questions, count a whole meal, build recipes to a macro target, and track what you actually eat.
- Search any food
- Count a full meal
- Recipes to your macros
- Scan a plate or label
Why it's different: the numbers are calculated from a fixed ingredient database rather than guessed, and when a target is not physically achievable the app says so instead of inventing a figure.
