With the continuous improvement of people's living standards, dietary structure changes, China's cardiovascular and cerebrovascular diseases and the number of deaths are also rising, the number of deaths of which The proportion of China's total mortality rate has even reached about 40% , high blood pressure has become a worrying problem. And eating less salt is one of the practices to combat hypertension.

Then people in the 1950s and 1960s ate salted vegetables every day, so why aren't more people suffering from high blood pressure than now?

The nature of eating pickles in the 1950s and 1960s:

①The body needs more

People in the 1950s and 1960s were mainly engaged in physical labor, and sweating from physical labor would excrete a large amount of salt, and after a lot of labor, it itself would require a greater intake of salt, so although people consumed more salt, it would not end up causing an excessive imbalance in the body.

②Sodium is a relatively single source, the total amount is not more than now

The 1950s and 1960s dishes are more salty, but the total amount of dishes is very small, the food is mainly unsalted staple food, a big bowl of rice on a small dish of salted vegetables is a meal, and processed food is very little, the source of sodium is almost salt, the total intake of sodium is not more than now.

③Balance of sodium and potassium

According to domestic and international research, sufficient potassium can balance the pressurizing effect of sodium and promote the excretion of sodium. In the 1950s and 1960s, there was a shortage of food, grains and beans, potatoes and vegetables and fruits, all of which were food for everyone, and relatively speaking, the proportion of people eating refined white rice and white flour was relatively small, and all of these foods are rich in potassium, which ensures adequate intake of potassium.

And in modern life,people no longer need so much physical labor, sweat is also less, salt intake has gradually increased, we eat a lot of food contains a lot of sodium, so it leads to the proportion of serious imbalance. The chances of developing high blood pressure have also increased.
