As a young girl I loved sour things. Rhubarb, green apples, dill pickles, gooseberries, black raspberries and cherries, but I especially loved to eat lemons. My parents had a fit claiming that I would get sick or get a belly ache from all of those sour things.  Eating them in abundance never seemed to bother me, and no doubt they were more nutritious than the typical diet of today.
