4hw.com.cn: do you have a heavy taste? Recently, salt eating has become a hot topic again. According to the latest data, Chinese people eat too salty. According to the suggestions of Chinese dietary guidelines, the amount of salt for adults is suggested to be 6G, while the average daily salt for adults in China is 10.5G, far exceeding the standard. Do you know the harm of salt eating? Let's have a look.
Salt is the first of all tastes. Many dishes are saltless. In addition to seasoning, salt can maintain the osmotic pressure of extracellular fluid, participate in the regulation of acid-base balance in vivo, participate in the generation of gastric acid and increase appetite, which is indispensable in maintaining physiological function.
In fact, animals also need salt. Many animals will lick the saline alkali soil to supplement salt.
Under normal circumstances, how much salt does a person need to eat every day? I'm afraid very few people can quantify it.
What harm does salt do?
According to the 2016 dietary guidelines for Chinese residents, it is recommended that adults should not consume more than 6 grams of salt per day, while less than 5 grams of salt per day is enough to meet the needs of the body.
According to the Chinese society of nutrition, China is currently one of the countries with the highest salt intake in the world. In 2012, the average daily salt intake of residents aged 18 and over in China was 10.5G, 75% higher than the recommended 6G.
In particular, some elderly people, due to the age of the taste has declined, eat very salty food.
What's the harm of eating too salty? One of the main components of salt is sodium ion. The Chinese society of nutrition points out that high sodium intake, as an independent risk factor, is an important risk factor for hypertension, cardiovascular disease, gastric cancer and other diseases, and has become a serious health risk affecting the health and life expectancy of Chinese residents, with a wide coverage.
From this point of view, it is very necessary to carry out the 'salt reduction operation', and the government has also put forward the goal.
In July 2017, the general office of the State Council issued the national nutrition plan (2017-2030), which proposed to reduce the per capita daily salt intake by 20% by 2030.
In addition, according to the medium and long term plan for the prevention and control of chronic diseases in China (2017-2025) issued by the general office of the State Council in the same year, the per capita daily salt intake in China has decreased by 10% by 2020 and 15% by 2025 at the current baseline level of 10.5G.
