Each kilogram of toon about 1.475 ~ 2.778 mg of nitrite, the content is higher than the general vegetables.
And nitrite is metabolized in our body to produce a substance called nitrosamine, which is a strong carcinogen.
In addition to causing cancer, nitrites can also cause poisoning. Symptoms include chest tightness, breathing difficulties, dizziness, headache, palpitations and so on. In severe cases, nausea, vomiting, shock, coma and other conditions can also occur, and even life-threatening. However, the Food and Agriculture Organization of the United Nations and the World Health Organization, the permissible daily intake of nitrite is 0.2mg/kg. Calculated, a body weight of 60 kilograms of adults, a day to eat 4 kilograms of toon to exceed the maximum intake value.
