“People in the Middle Ages were short because they didn't eat well.”

The idea that individuals in the Middle Ages were notably shorter than people today is a common observation, often attributed solely to a perceived lack of adequate nutrition. This simplification stems from a general understanding that modern diets are more robust and varied, leading to an assumption that our ancestors simply didn't eat enough or the right kinds of food to reach their full height potential. While this notion holds a kernel of truth, the full picture is far more intricate than just dietary intake.

Historical and scientific evidence, primarily from the study of skeletal remains, reveals that medieval populations were indeed, on average, shorter than their modern counterparts. However, this wasn't solely due to a poor diet. Chronic diseases, rampant during the era due to poor sanitation and limited medical knowledge, significantly impacted growth and development. Furthermore, the demanding physical labor expected from a young age, particularly in agricultural societies, placed immense stress on bodies, often stunting growth. Famines were also a recurring threat, leading to periods of severe nutritional deprivation that could have lasting effects. It's also important to note that height varied considerably by region and social class, with wealthier individuals often enjoying better nutrition and fewer physical demands, leading to greater stature.

This enduring belief persists because it offers a seemingly logical and easy-to-grasp explanation for the noticeable difference in average height between historical and contemporary populations. The direct comparison between our calorie-rich, diverse modern diets and what we imagine as the meager fare of the past makes poor nutrition a readily understandable scapegoat. This simple narrative often overshadows the complex interplay of environmental stressors, disease burdens, and societal structures that collectively shaped the physical development of people in the Middle Ages.
