Small pickles are a very popular food for many people nowadays, especially in the morning!
Speaking of pickles, in the past 50s and 60s, people were relatively poor, and at that time, they could only pickle fresh vegetables, which could be preserved for a long time and controlled intake.
The older generation of people eat more pickles every day, but their risk of high blood pressure and cancer is relatively low, pickles are a high-salt food, even if people now control the content of eating pickles, it also increases the risk of many chronic diseases.
Compared with the older generation, why does eating pickles increase the number of diseases now?
Why do the older generation often eat pickles because they are poor, but rarely have high blood pressure and cancer? Tell you the truth
People now have more ways to consume extra salt
Now people consume too much salt than before, increasing the risk of high blood pressure, cancer.
In the past, people used to have a relatively simple way of obtaining table salt, and there were fewer options to choose from, even if they ingested some foods with higher salt content, they could not fully supplement the amount of salt needed by the human body.
With the development of the times, the range of people's recipes has gradually increased, the variety of dishes has increased, the spices have become richer, and the way to consume additional salt has also increased.
Now people's diet is more refined
The mainland's fine diet has led to an increase in obesity rates, and eating too many staple foods has led to a more serious obesity situation, when the obesity rate increases, chronic diseases such as hypertension and hyperlipidemia will follow, increasing the risk of cardiovascular disease, so for these people who eat a fine diet for a long time, it may be difficult to live long.
Nowadays, the amount of manual labor in people has decreased
In the 1950s and 1960s, because the problem of food and clothing had not yet been solved, and in preparation for industrialization, most people needed to work in the fields, first to maintain their livelihood and second, to produce.
When people sweat like rain in the field, the salt in the body will also be excreted with sweat, so the loss of salt will be more.
Modern people are mostly office workers, and they eat very salty every day, so that the intake of salt is easily excessive.
Life expectancy has now increased
From the perspective of the normal degree of aging of the human body, most diseases are older and the incidence is higher.
Clinical data show that the risk of disease is 3.3% at the age of 51 to 60 years old; the incidence is 5.9% at the age of 61 to 70 years; 9.3% at the age of 71 to 80 years; and the highest is 16.7% at the age of 81.
Although the world's population is aging, but usually, most people's life expectancy will end at the age of 70 or 80 years old, so many cancers caused by aging may have the possibility of decreasing incidence.
Why do people have to eat salt?
In fact, what the human body needs is not salt, but sodium ions in salt. Salt is sodium chloride, which is decomposed into sodium and chloride ions when exposed to water, and is the compound with the highest sodium ions in nature.
Biologically speaking, sodium is an important inorganic element in the human body, accounting for about 0.15% of human body weight.
This positively charged cation has an important role in regulating the amount of water in the human body, maintaining the acid-base balance, and stabilizing blood pressure, since people now cannot do without salt.
Pickles, are the "accomplices" of high blood pressure and cancer?
Pickles are vegetables marinated for a certain period of time with salt and other seasonings, usually the taste is salty, can be stored for a long time, the main ingredients are soy sauce, cucumbers, vegetables and other foods.
Generally, some nutrients will be preserved after pickling, such as vitamins and other components, which can appropriately supplement the trace elements needed in the patient's body.
Then the human body ingests too much salt will lead to a retention between water and sodium salts in the body, resulting in swelling of the smooth muscles of blood vessels, thinning of duct cavities, and increased vascular resistance.
At the same time, the volume of blood increases, the burden on the heart and kidneys increases, and this time there will be a rise in blood pressure, that is, a manifestation of hypertension. An off-forest high-salt diet increases proteinuria and loss of glomeruli, which leads to high blood pressure.
Pickles also contain nitrite, the main component of nitrite is nitrite, if the nitrite amine is long-term ingestion by the human body, it is easy to increase the chance of cancer, so now there is a probability of carcinogenesis.
So, how much salt is appropriate to eat per day?
WHO recommends that adults consume no more than 5 g of salt per day, but according to studies, most people have more than twice the recommended intake of salt intake, between 9 g and 12 g of salt per day.
Due to changes in people's dietary habits and taste preferences, at present, salt intake far exceeds the level of 3 grams. According to the 2002 Nutrition and Health Survey of Chinese Residents:
Mainland residents consume an average of 12 grams of salt per person, 10.9 grams for urban people and 12.4 grams for rural people, and the Chinese Nutrition Society recommends that the intake of salt (including salt in soy sauce and other foods) for adults is 6 grams a day.
