Whether you are on a diet or just want to be healthier, you might be one of those millions of people around the planet who use a mobile app to track everything you eat. The trend has arrived in space.  According to ESA on September 14 that European astronauts are now logging their meals on a tablet to make sure they are getting the right amount of nutrients.

An optimal diet, paired with constant exercise, is essential to counteract the effects of spaceflight on the human body. Bone loss, muscle atrophy and depleted nutrient stores such as protein, fat and vitamin D are among the negatives of space travel.

Research shows that energy intake in orbit is usually lower than on Earth – some even call it ‘spaceflight anorexia’. From tubes to cans and rehydratable packages, space food has evolved to meet nutritional requirements and boost crew morale.

“Food in space tastes different – it is like eating with a cold and a reduced appetite follows,” explains ESA astronaut Thomas Pesquet.

Since gaining weight is very unusual for astronauts, flight surgeons have always consulted astronauts when building their menus. Doctors want to ensure the crew are fuelling themselves with a balanced diet, suitable for space demands and the return to Earth. 

Every meal on EveryWear

EveryWear is an iPad-based application that collects physiology and medical data from astronauts on the International Space Station. It is connected to wearable biomedical sensors that record exercise, heart rate and sleep quality. 

Its main use is as a food diary. The astronaut simply scans the barcode of the food with the built-in tablet camera, classify it as breakfast, lunch dinner or snack, and add how water was consumed.

“We wanted to move away from the old-fashioned questionnaires and snapping photos in orbit. It is cumbersome both for astronauts and the scientists on Earth,” says Brigitte Godard, ESA’s flight surgeon in charge of astronaut nutrition.

The crew can also add food by tapping on a specific product. The app comes loaded with a database containing all the food on the Space Station, both in English and in Russian. If something is not listed yet, there is an option to take a picture. 

Nutritional advice

An added value of the tool is that it connects the astronaut with nutrition experts on Earth, some 400 km below. Ground teams receive the information and can suggest the best combination of meals for a healthy stay in orbit.

In addition to the weekly expert advice, the app delivers automated nutrition reports for astronauts to monitor their daily intake and check the recommended dose. The focus is on calories, protein, water, carbohydrates, fat, sodium, calcium, iron and potassium.
