И еще вдогонку - даже для упомянутой Ирландии увеличение деторождения все равно связано с картошкой, в период с 1750 до 1850 гг: In addition, the change in diet, which included potatoes also affected the birth rate For example, recall that there was an increase in the Irish population between 1750 and 1850. The reduced fertility in European was believed to be due to the consumption of Rye that had been contaminated with Ergot of Rye, a disease of Rye. Mycotoxins and Mycotoxicoses: Aflatoxin http://www.botany.hawaii.edu/faculty/wong/BOT135/lect11.htm Потом там случилась с картошкой беда от другого грибка, и рожь вернулась. А в России к тому времени картофель еще только-только сажать начали.
