Astronauti jsou daleko od obchod\u016f, a proto jsou odk\u00e1z\u00e1ni na pravideln\u00e9 dod\u00e1vky potravin. Ka\u017ed\u00fdch n\u011bkolik m\u011bs\u00edc\u016f k nim doraz\u00ed automatick\u00e1 kosmick\u00e1 lo\u010f, jako je nap\u0159\u00edklad Automated Transfer Vehicle agentury ESA nebo rusk\u00fd Progress, nalo\u017een\u00e1 \u010derstv\u00fdm ovocem, vodou a p\u0159edem zabalen\u00fdmi j\u00eddly.<\/p>\n<\/div>\n

Dnes se vesm\u00edrn\u00e1 strava podob\u00e1 t\u00e9, kterou j\u00edme ka\u017ed\u00fd den na Zemi. Pat\u0159\u00ed k n\u00ed mra\u017een\u00e1 zelenina a dezerty, chlazen\u00e9 potraviny, ovoce a ml\u00e9\u010dn\u00e9 v\u00fdrobky. Dnes obsahuje j\u00eddeln\u00ed\u010dek na Mezin\u00e1rodn\u00ed vesm\u00edrn\u00e9 stanici v\u00edce ne\u017e 100 polo\u017eek.

K dispozici jsou tak\u00e9 dochucovadla, jako je ke\u010dup, ho\u0159\u010dice a majon\u00e9za. K dispozici je i s\u016fl a pep\u0159, av\u0161ak pouze v tekut\u00e9 form\u011b.<\/p>\n
