Background

With the development of science and technology and the improvement of living standard, people pay more and more attention to drinking water with health care function. The content of deuterium in general drinking water is between 139 ppm and 150ppm, and a large number of research results show that deuterium is harmful to the survival of living bodies, and mainly because deuterium atoms replace hydrogen atoms to generate additional stress in a DNA spiral structure, so that the phase shift, the breakage and the replacement of DNA double helix are caused, ribonucleic acid is disordered in arrangement and even resynthesis, mutation is caused, and the cancerization probability in the cell replication process is increased. The deuterium-depleted water is water with reduced deuterium element, and can reduce the error and canceration probability in the human cell replication process. Meanwhile, the deuterium-depleted water molecular group is changed into a smaller and more stable high-energy-state structure, the diameter of the water molecular group is close to that of a hydrophilic channel of a cell membrane, so that the deuterium-depleted water molecular group can more easily pass through the water channel of the cell membrane, more nutrients, mineral substances and oxygen beneficial to a human body are carried, the deuterium-depleted water molecular group enters each corner of the cell, and meanwhile, the nutrients which cannot be completely absorbed by the cell and fat, cholesterol and other substances accumulated by the body can be fully dissolved and discharged out of the body, so that the toxin expelling and detoxifying capability of the body is improved. Basic medical research shows that 63 common diseases of human, such as metabolic syndrome, Parkinson, cancer, various inflammations, constipation, hepatitis B and the like, are caused by oxidative damage, hydrogen has the function of selectively neutralizing malignant oxygen free radicals in vivo, and the concentration of the hydrogen reaches 3/4 saturation, namely 1.2ppm is enough to generate biological effect, so that a new breakthrough is found for human to resist various chronic diseases.
