CARRILLO-ESPER, Raúl  and  ZEPEDA-MENDOZA, Adriana Denise. Nutritional aspects in space flights. Rev. Fac. Med. (Méx.) [online]. 2017, vol.60, n.6, pp.47-50. ISSN 2448-4865.

The food that NASA's early astronauts ate in space is a testament of their strength. John Glenn, America's first man to eat anything in the near-weightless environment of the Earth's orbit, found the task extremely hard and the menu to be quite limited. Other Mercury astronauts had to base their nutrition on bite-sized cubes, freeze-dried powders and semi-liquids packaged in aluminum tubes. Most of them agreed that the foods were unappetizing and disliked squeezing the tubes. Moreover, freeze-dried foods were hard to rehydrate and the crumbs got stuck on the walls of the spacecraft. Ever since, multiple technologies and studies on the energy requirements of astronauts and food preservation have been developed.
