Why were the franks shorter than Canadians are today?

The Franks, a Germanic tribe that settled in what is now France and Germany during the early Middle Ages, were generally shorter than modern Canadians due to a combination of factors including nutrition, health care, and genetics. During the early medieval period, diets were less varied and often lacking in essential nutrients, which affected overall growth and development. Additionally, living conditions, prevalence of disease, and lifestyle choices of the time contributed to shorter average heights. In contrast, modern Canadians benefit from improved nutrition, healthcare, and living standards, leading to taller averages.
