I agree. “Overfed but undernourished” would make a great book title (but I believe a documentary already stole it…)
Your comment prompted me to look up data on scurvy. It seems that clinical cases are rare, but that approximately 7% of Americans are deficient in vitamin C based on blood tests.
This study found that white men had the highest rates of low Vit C levels (12%). They also found greater vit C deficiency rates in smokers and lower socioeconomic status.
This is truly alarming, not so much because of scurvy persay, but because this means these people are eating vanishingly small amounts of fruits and veg. Vit C is one of the easiest nutrients to get in abundance across most produce. For example, all it takes is about a third cup of red bell pepper to meet your daily vitamin C needs!
