Guide to life after nuclear-polluted water is discharged into the sea - Supplementing probiotics
Nuclear-polluted water contains a large amount of radioactive elements. Although the nuclear wastewater has been treated by a so-called nuclide removal device (ALPS) before discharge, it still contains some nuclides, the highest content of which is tritium (hydrogen isotope), followed by Contains carbon-14, cobalt-60, strontium-90, etc. These nuclides can undergo beta decay, releasing beta particles. The main ways for radioactive substances to enter the human body are through the respiratory tract, digestive tract, skin, wounds, etc. In addition, due to the enrichment of marine organisms, these radioactive elements have more complex and long-term effects on the human body, which can cause DNA damage and lead to human cell death or potential genetic mutations.
How to reduce the hazards of nuclear radiation through diet.
1. Appropriate amount of iodine-containing food
The mechanism of iodine to prevent radiation is to increase the saturation of iodine in the human thyroid by taking "stabilized iodine" to avoid the deposition of radioactive iodine in the thyroid, thereby avoiding the harm of radioactive iodine to the thyroid. However, please note that eating iodine food does not mean eating iodized salt. Normal adults need to consume 4kg of iodized salt at one time, that is, 4kg, in order to reach the "stable iodine" single intake dose of 100mg recommended by WHO, which is far beyond the daily dose of iodine in my country. Recommended daily salt intake.
2. Antioxidant-rich foods
Nuclear radiation can generate a large number of free radicals in the body and cause oxidative stress. Therefore, in order to resist free radical attack, we should eat more foods rich in antioxidants, such as citrus fruits, berry fruits, nuts, tea, grape seed extract, etc.
3. Eat more fiber-rich foods
Cellulose can increase intestinal peristalsis and promote defecation, thereby helping to expel radioactive substances and other harmful substances from the body.
4. Supplement with probiotics
Radiation disrupts the intestinal barrier and mucus layer, leading to bacterial translocation and activation of the inflammatory response. Dysbiosis, whether induced by radiation or other factors, can affect local and systemic immune responses. Probiotics attenuate radiation-induced gastrointestinal injury by regulating oxidative stress and inflammatory processes, intestinal permeability, mucus layer composition, epithelial repair, resistance to harmful substances, and stimulation of expression and release of immune effector molecules in the gut.
The study of Lactobacillus johnsonii LBJ456 originated from a project funded by NASA on the effect of gut microbiota on high linear energy transfer radiation-mediated toxicity and genome instability. Through mouse experiments, it has been confirmed that Lactobacillus johnsonii LBJ 456 can reduce the level of oxidative stress and the generation of systemic inflammation, thereby reducing genotoxicity and reducing the damage caused by radiation to the body. In addition, Lactobacillus johnsonii LBJ 456 can also prevent radiation-induced morphological changes in the intestinal mucosa of mice, and relieve radiation-induced diarrhea and other adverse reactions.
At present, the Lactobacillus johnsonii LBJ 456 industrialized by Probioway has been widely used in radiation protection, post-radiotherapy recovery, and other fields.
