The nutritional content of each traveler 's meals when working in space is the same as when they are on Earth, except to add iron (to produce red blood cells), vitamin D and Sodium (limiting osteoporosis).

During NASA flights, astronauts often carry foods such as cereals, eggs, pasta and cheese, creamy mushroom soup, chicken and rice, beef mushroom sauce, tuna and fish Anise, eggplant and tomato, ham, granola bar, cookies and nuts, bread and corn bread, do not crumble.

The diet of astronauts.

Drinks include coffee, tea, orange juice, lemon juice, and also fresh fruit, but must be eaten in the first few days.

Food and drinks in space are preserved by the way she runs out of water. Only when eating, water is added.

Food for astronauts is dehydrated to kill harmful microorganisms and enzymes. Fruit and fish are canned, and other foods are contained in plastic bags and must be heated before eating. Drinks are stored in pressed packs, and fruits and vegetables are stored in a special cabinet.

NASA is developing a program to provide clean food in space. They selected 10 types of plants with high nutritional content such as cabbage, carrots, lettuce, tomatoes, green onions, spinach, radish, bell peppers, strawberries and fresh herbs.

In the future, scientists might build a hydroponic laboratory to grow crops like potatoes, rice, peanuts, dried beans and wheat.

This plan is probably a long way from being realized because NASA's new food program is aimed at serving up to 18 months on Mars.
