As part of the work, its authors took the remains of six Indians who inhabited the Amazon coast in a time period from the first millennium AD. until 1800. Isotopic analysis of carbon and nitrogen for bone collagen was carried out, samples of soil and some species of animals of that period, including fish, were studied separately. At the final stage, the collected data was compared. As it turned out, before the influx of Europeans, the diet of the inhabitants of modern Brazil consisted mainly of plants in conjunction with land mammals. Among the latter, the dominant roles were played by rodents and mazams.
The Indians paid much attention to hunting these representatives of the fauna. In addition, common foods were corn, sweet potatoes, pumpkin and cassava are mentioned. However, no evidence has been found that the inhabitants of America before Columbus arrived there leaned on fish, writes Planet Today. This may be due to the relatively small number of inspected remains.
