Astronauts should eat space-grown vegetables.
Astronauts should tuck into salads in space
Experts have found that the most nutritious meals for space travellers on long missions can be created using ingredients that are grown on missions.
Researchers from the American Chemical Society say that the dishes need to include kale, sweet potato and sunflower seeds as they have all the vitamins and minerals that are needed to compensate for the additional calories burned in zero-gravity conditions.
A spokesman for the group said: "Astronauts burn more calories than humans on Earth and require extra micronutrients, such as calcium, to stay healthy during extended exposure to microgravity."
Four people were invited to taste test the space salad recipe and claimed to have enjoyed it, although the society stressed that astronauts would have to "grow food in a sustainable, circular way within the spacecraft".
