ADD: rickets was common in England in the 17th century due to dietary changes, and it took a while for the cause and solution to be figured out: a legal requirement to fortify some foods with vitamin D. What rising disorders today are caused by dietary changes? Austism? Infertility? You'd think we'd be much quicker at finding a dietary cause today - unless the ones we haven't found yet are harder to find. One of the greatest health problems today has a obvious relationship to calories: obesity. Perhaps simply getting more calaries for the same mass of food is a factor? Or, maybe our feeling of hunger is triggered by a lack of nutrients other than calories? So we eat and eat but are not satisfied.
