Description

nutritional preparation suitable for improving eyesight of astronauts
Technical Field
the invention belongs to the technical field of food processing, and particularly relates to a nutritional preparation suitable for improving eyesight of astronauts.
background
studies have shown that under the microgravity effect, humans have elevated intraocular pressure and a high probability of a decrease in overall visual ability. A survey published in 2011 found that 29% of the astronauts who underwent short-term flight missions and 60% of the astronauts who underwent long-term flight missions reflected suffering from varying degrees of visual problems. In addition, at least 7 astronauts related cases recorded on the case exist, and the astronauts with healthy eyes need to perform vision adjustment after returning to the earth; some astronauts have blurred vision lasting for weeks, others last longer, and may not even recover the original vision. The astronauts are the main bodies and the cores of manned space activities, and in the face of complex and variable space environments lacking gravity, the change of the operation capacity of the astronauts is the content of primary focus of attention of various countries for starting manned space missions. Among these, the visual ability problem is particularly noticeable, since vision is almost closely related to the performance of astronauts in all tasks. Therefore, in order to ensure that the astronauts can smoothly perform tasks in space and quickly recover the eyesight after returning to the earth, appropriate measures need to be taken to prevent and treat the problem of vision degradation of the astronauts in the severe environment of space.
The food therapy is guided by the concept of 'homology of medicine and food and medicine', and achieves the purposes of maintaining the body, treating diseases, keeping healthy and prolonging life by using the dual-purpose medicine and food. Chinese diet therapy has a long source and a history of three thousand years. In the process of searching for food, the original human finds some food to be medicinal and uses it to treat diseases. In the West week, the dietotherapy and the food sense organ are placed, and the nutrition and the health care of the food are taken into consideration. The Han Tang dynasty is the stage of food therapy development in China. The early medical dictionary, Huangdi's Canon, describes the effect of various foods on various parts of the human body. After the Han Dynasty, the discussion about diet therapy continuously appeared, and the diet therapy enters the prosperous stage by the appearance of the special diet therapy of Sun Simiao in Tang Dynasty. The research on food therapy in the later generations is more intensive and the practice is more extensive. The compendium of materia medica of Li Shizhen in the Ming Dynasty lists a lot of edible plants as medicines, and the Qing Dynasty emphasizes that people take food as nourishment, so that the theory and practice of food therapy are more perfect. Generally, long-term development and practice are carried out, China forms a relatively perfect food therapy food theory, and accumulates very rich experiences of health care and disease treatment by using daily food and drink. Wherein, the dietotherapy method and experience related to eye protection and eye disease treatment are not lacked.
