They can eat whatever they want as we see on the pictures!
80% of food for astronauts is developed at the Research Institute of Food and Concentrate Industry of the Biryulyovsky experimental plant. Over 300 cosmic dishes developed in general. Each is strictly tested by astronauts themselves, they estimate food to their own taste.
Now they have “a sixteen days menu” with changing foods, when sixteen days are over they have another menu for other sixteen days in space. Dishes should not pall and disappoint astronauts. 20% of food is supplied by private well-reputed companies.
In extreme space conditions, according to specialists, astronauts must eat four times a day with an interval between meals of at least five hours. Daily menu must include:
300 grams of carbohydrates;
100 grams of proteins;
118 grams of fats.
Food is in metal cans and plastic packages. The daily ratio for an astronaut costs approximately 20 thousand rubles ($300). The expensive price is explained by high cost of delivery. They pay $5-8 thousand dollars to send a kilogram of load to the ISS.
A crew member in space should consume 3200 calories daily (while on the Earth a man needs average 2200-2600 calories).
Apart from the main menu they can treat themselves to something particularly tasty. Fruit jam, for example.
Ketchup and canned foods.
And even pizza, why not? They made it themselves right there.
More tasty foods are available on holidays.
Cakes, for example.
No more tubes! They remained in the past!
Space grown lettuce is said to be yummy.
Got the snack!
A piece of a hovering cosmic sandwich.
Yes, they have enough tasty food but they still miss the one cooked at home by beloved women.
