For thousands of years, fuel was fuel for man's successes and failures. This is especially true when it comes to space channels.
It is imperative not to prevent the birds being heavy when they are pregnant. going, and sometimes lasting for months.
But today's science has nutrition longer than that. Its aim is to bring the highest performance from the crew and reduce the cumulative effects of a & # 39; live in the acronym, and a & # 39; prevent long-term health hazards such as cancer and heart disease.
The attempts to take care to eat the hands of humans into the foolish space may be the efforts.
But every new search in a global search, such as & # 39; Most of the previous ones, who & # 39; directly affect those who stayed on Earth.
Bad vision and fertility: where is the connection?
Some stomachs come back from the spot with eye problems. Among these problems, there are events at the bottom of the eye called "fleas of wadding" – a small spot on the retina – and the eye blows well.
In other words: some of the opponents left their planet with the comprehensive vision, and when they returned, they would need glasses.
Initially, it was considered that the impact was; Microgravity has been guilty of disorder, resulting in changes in body fluid and increased brain pressure.
But these theories do not explain why there are only 30-40 per cent of astronauts in eye problems. Is there another reason?
Our theory is that genetic variation affects how blood vessels work
When it accompanies the trigger that is present at a space of space – such as changes in the bed – we will getting cruel blood vessels and around the eye. This causes more weight, leading to eye problems.
In crew members with these signals, a much higher collection of designated homocysteine compounds was established, not only when they were; live and return to Earth, but even before the trip.
Homocysteine is part of a bio-chemical process that is practically occurring in all cells in the cell; body and look for different types of life B to play.
Strongers who identify eye problems due to their genetic complication may require higher dose of vitamin B than others.
An interesting fact in this study is that women with polycystic ovarian sionndrom (PCOS) know that they have high homocysteine acidity, as well as similar circulatory problems in astronauts (men) with eye problems.
PCOS will affect the work of last year. The main reason for fertility problems is and it is considered that 20% of all women suffer from it.
This disease has not been fully investigated and there is currently no cure. But it is also possible for women with PCOS, because they have the same number of blood cells, maybe vitamin B is over.
For this, there is no final evidence, but NASA and doctors at Mejo Clinic in Minnesota are working on investigations to investigate potential relationships.
This research is capable of destroying one of the key risks in the spatial initiatives, but also to enhance the understanding of the syndrome that affects millions of people.
Lack of sunlight
Our skin produces vitamin D when it is open to the sun. It is essential for the health of the bones, the teeth and the muscles.
Astronauts are not getting enough of vitamin D when they are working in the cell; globe, because they are protected from seeing goodness, and they do not. get enough off from what they eat.
To investigate the impact of sunlight, we worked with the winter teams at the Makmurdo Research Center in Antarctica, where it did not. sun stopped for six months.
We tested there to find out if to add more vitamin D a & # 39; Give enough space to sunlight.
The first survey showed that there were smaller smaller sizes; Increased vitamin D levels, but higher dose did not have a big impact.
When the American National Academy of America increased the level of Vitamin D required in North America, this study, along with many others, helped to make this decision.
We also found that there is a body's weight, or large body index (BMI), which impacts on the success of & # 39; is a reform application.
It makes sense, because there is a fat; Break out vitamin D and prevent preventing it from being kept in the blood.
In our second study, we stressed our attention to the work of the defense and stress system, which disturb the birds and the teams that are in the process. affecting the Antarctica.
We have discovered that these factors appear to be in collaboration. Typically, people with stress symptoms and a low level of vitamin D were more difficult to deal with viruses such as herpes, which were inserted into their bodies.
In vitamin D surveys, the subjects were usually at least somewhat exposed to the sun, which could destroy the result. These analyzes in Antarctica have allowed us to close this factor and have confirmed that the new vitamin D otters that are proposed for the wider population are & # 39; makes sense, but that little is needed from the elevated dose.
The secret of stronger bones
A bone loss is one of the biggest problems for passengers. Around 1% of astroauts lose around a month, which is the loss lost by osteoporosis in one year.
Mass disappears because the body does not. imposes a high blood pressure, and so it is "a decision" that you can survive with a smaller skeleton. On average, it will take years after one's intention, that a great deal of damage is done; to return.
After many years of successful and unsuccessful attempts, it has found that there are several specific changes in a diet that have a positive effect on bone health.
Astronauts that eat more fish such as salmon and mackerel are less likely to lose their bone in orbit. We also found that children with more fruit and vegetables help to strengthen their bones.
Compared to this, the prevention of high iron and sodium prevents the loss of a bone.
The results show that there were astronauts that were; fed well, giving enough vitamin D, and there was no regular exercise; suffering from bone loss during a six-month space mission mission.
This is a & # 39; the first time in 50 years of human flying to the global globe that members made; close keeping of their bones only through diet and exercise.
These results have a direct impact on anyone on Earth, where these changes can keep your healthy bones.
A pipe on the road
As we come to the sixth decade of the human being's travel, we Standing at a human entrance gateway into the place. Combined health risks are important and proper nutrition may be necessary for longer periods and more methods to other planets, such as Mars.
We need to use and expand nutrition information in the 21st century and bring together medical and scientific teams to research into the future, while at the same time benefiting the human race to whole.
