Called the condition for the successful development of Mars 

Scientists at Harvard University (USA) have found that resveratrol contained in red wine prevents muscle loss in rats that lived in conditions of reduced gravity, characteristic of Mars. This substance will help to cope with the adverse effects of microgravity on the body of colonists. This is reported in a press release on Phys.org.
To imitate the attraction on Mars, rodents were suspended from the ceiling of the cage with a tether covering the entire body. 24 male rats were exposed to either normal load (terrestrial conditions) or reduced to 40 percent within 14 days. In each group, one half of the animals received resveratrol (150 milligrams per kilogram of body weight per day), and the other received only water.
Researchers measured the circumference of the lower leg weekly, as well as the grip force of the fore and hind limbs, and 14 days later they estimated the strength of the lower leg muscles. It turned out that the Martian conditions of gravity weakened the functions of the muscles, reduced their weight and their fiber content. However, the addition of resveratrol to food retained the state of the front and hind legs at the level of rodents in the “earth” group.
At the same time, the protection was not complete: the additive did not completely compensate for the loss of the average cross-sectional area of ​​the plantar and gastrocnemius muscle fibers. The positive effect itself is due to increased insulin sensitivity and better absorption of glucose. This is true for astronauts who develop insulin resistance in microgravity.
