Medieval Bread: The 70% Diet Claim That Wasn't Just Bread
The idea that bread accounted for 70% of the medieval diet is repeated like a mantra. But historical data nuances this: not everyone ate the same, medieval bread differs greatly from today's, and the 70% figure only fits if we count porridge and soups, not loaves.
The notion that bread was the overwhelming base of medieval nutrition has merit. Cereals were cheap, preserved well, and lower classes had little access to fresh meat or fish. A practical analysis: dry bread can be soaked and lasts a week, while cooked legumes spoil in hours in homes without proper kitchens. In cities, dependence on bread was even higher. But here comes the first nuance.
Then vs. Now: Medieval Bread Isn't Today's Bread
Medieval wheat was different: low-yield varieties, coarse milling, wholemeal flour including bran, and often rye, barley, or oats. During famines, acorns, beans, or even dirt were added. The result was dark, dense bread, less caloric than modern versions. This bread was often consumed as soup or porridge rather than sliced. The distinction between "bread" and "porridge" blurs.
Porridge, Farinetas, and the Threat of Lathyrism
In many Spanish regions, the daily dish was porridge made from grass pea flour (almorta), banned by Franco until 2018 due to lathyrism (neurotoxicity). This suggests massive cereal consumption persisted into the post-war era. In Teruel, for example, farinetas were eaten with lard or bacon. But in garden areas like Málaga, the diet was more varied: fruits, vegetables, legumes, and some pork. Geography marked brutal differences: the dry Meseta plateau isn't the same as the fertile coast.
Poor vs. Rich: Two Medieval Diets
Social class divided the table. The menu of Don Quixote's hidalgo—beef stew, salad, lentils, pikelet—consumed three-quarters of his income. For a day laborer, animal protein was a luxury reserved for antiestéticast days, with bread or porridge remaining the base. Doctors prescribed an egg with bacon to anemic children: a miraculous cure revealing habitual protein deficiency.
The Debate on the Exact Percentage
Was it 70%? It's a symbolic figure. Historians suggest cereals provided 60-80% of calories, but not all was eaten as bread: also as porridge, soups, beer, or flatbreads. Dependence decreased in spring and summer when fruits and vegetables were available. Pellagra, a niacin deficiency disease that ravaged southern Europe in the 18th century, shows that in many regions maize (as bread or porridge) was almost the sole food. Evidence of extremely monotonous diets.
The answer is that 70% is a pedagogical exaggeration, not scientific data. But the underlying reality is harsher: most of the medieval population lived on the brink of starvation, with cereals as their only caloric anchor. It may not be exactly 70%, but the spirit of the myth dangerously approaches the truth. And if you think we've overcome this today, look at current diets based on ultra-processed foods to see that monoculture remains a problem, now called refined wheat.
