盐不仅是人们日常生活中必不可少的调味品,又是人体内钠的主要来源。人体钠总量约占体重的0.15%,正常人每天摄食钠的含量约为70～200mmol,相当于摄入4～12克的食盐,就可以满足机体的代谢所需。虽然,盐摄入不足会使人产生疲乏。无力、尿少、口渴,头晕等症状,但是长期过多摄食,危害会更大。现代医学研究表明,人体内氯化钠浓度过高时,钠离子可抑制呼吸道细胞的活性,使细胞免疫能力降低,同时高钠抑制体内干扰素的生成,所以多吃盐的人患呼吸道感染,特
Salt is not only essential condiments in people’s daily lives, but also the main source of sodium in the body. Sodium accounts for about 0.15% of the total body weight, normal daily intake of sodium content of about 70 ~ 200mmol, equivalent to 4 to 12 grams of salt intake, you can meet the body’s metabolic needs. Although, salt intake will make people tired. Weakness, oliguria, thirst, dizziness and other symptoms, but long-term excessive feeding, the harm will be greater. Modern medical research shows that sodium chloride concentration in the human body is too high, sodium ions can inhibit the activity of respiratory cells, so that cellular immunity decreased, while high sodium inhibition of the body’s production of interferon, so eat more salt in people suffering from respiratory tract infections, special
