How many people with scurvy do you know? It's rare.
From Scurvy - Wikipedia
It takes at least a month of little to no vitamin C in the diet before symptoms occur.[1][2] In modern times, scurvy occurs most commonly in neglected children, people with mental disorders, unusual eating habits such as ARFID, alcoholism, and older people who live alone.[2] Other risk factors include intestinal malabsorption and dialysis.[2]
