Isn't it said that eating more salt gives me the strength to work? Why am I still sick? "Aunt Wu puzzled.

Aunt Wu is 58 years old this year and has been living in the countryside before. Due to her daughter-in-law having a child last year, she left the countryside to take her grandson to the city.

In the past month, she has occasionally feltDizziness and palpitationsI thought I was too tired with my children, didn't rest well, and didn't take them too seriously. One day, she was cooking when she suddenly fainted in front of her eyes as soon as it was dark. Her son hurriedly took her to the hospital.Upon examination, it was found that Aunt Wu's blood pressure had skyrocketed to 180/110mmHg, and she was diagnosed with hypertension.

When understanding past history, it was discovered that Aunt Wu's family had poor conditions since childhood and needed to do various physical tasks. Her education has always beenEat more salt to have the strength to workEvery day when cooking, a large amount of salt is added, and the taste is still very strong.

The doctor said that Aunt Wu's high blood pressure is related to her usual high salt dietEat more salt to have the strength to work

The European Heart Journal once published a study conducted by the University of Bern in SwedenStatistics were conducted on data from 181 countries/regionsAfter analysis, it was found that an increase in sodium intake was associated with an increase in life expectancy and a decrease in all cause mortality.

After adjusting for factors such as BMI, researchers found thatAdding 2.5g of table salt (1g of sodium) daily will increase life expectancy at birth by 2.6 years, increase it by 0.3 years at the age of 60, and reduce the all-cause mortality rate by 131 people per 100000 people. That is to say, the saltier you eat, the longer your lifespan will be.

Does this mean that eating more salt is better for health?

Of course not, this study was based on the exclusion of factors affecting BMI and GDP in various countriesThe conclusion is not rigorous and has not received recognition from the medical community. Additionally,The author of the paper also clearly pointed out that this study is only an observational result and cannot serve as a guide for nutritional interventions.

In 2019, the authoritative magazine The Lancet published a study showing that in 2017, among 195 countries and regions worldwide,China ranks first in the world in terms of deaths caused by dietary issues! And a high salt diet is one of the three factors that cause the highest mortality rate.Salt is an essential seasoning in daily life, which can make food more delicious. However, eating too much salt can also cause a series of harm to the body.

1. Not conducive to cardiovascular health

High salt intake can disrupt the balance of water and sodium in the body, increase vascular pressure, accelerate vascular aging, and thus easily causeHypertension and stroke are moderate cardiovascular diseases.It may also causeRenal function damageRenal function damage

2. More prone to fractures

Excessive intake of sodium can inhibit bone cell differentiation and normal function,Easy to cause a decrease in bone density and strengthThis in turn increases the risk of fractures.

3. Increased risk of gastritis

Excessive salt intake will cause adverse irritation to Gastric mucosa, which is easy toCauses Parietal cell to fall off, increasing the risk of gastritisContinuous stimulation may also lead to the development of gastric cancer.

4. Impact cognition

Long term high salt diet can increase oxidative stress in the hippocampus tissue and intestinal inflammatory response, which can easily lead toMemory impairment and brain cognitive function impairment increase the risk of Alzheimer's disease.

So, in daily life, it is necessary to control the intake of salt, not to say that one cannot eat salt, but to eat salt in moderation.China's dietary guidelines recommend that the daily salt intake of adults should be below 5g.

Researchers from Peking University have conducted a large randomized controlled study to evaluate the impact of low sodium salt instead of common salt on the incidence rate and mortality of cardiovascular diseases in China.The results showed that if the Chinese people changed their regular table salt to low sodium salt, it could potentially reduce cardiovascular deaths by 450000 cases per year.

Previously, Taiwan, China, China, had done similar research, and found that the use of low sodium salt can reduce cardiovascular death.

However, although low sodium salts can greatly help reduce the risk of cardiovascular deathNot everyone is suitable to eat, these three types of people should be cautious:

• People with poor kidney function:The content of potassium element in low sodium salt is high, and potassium element needs to be passed or even excreted after entering the body. People with poor renal function are likely to be unable to excrete potassium ion in time when they eat low sodium salt, and Hyperkalemia is likely to be induced after a long time.
• People taking antihypertensive drugs such as "Puli" and "Sartan": Such drugs can inhibit the excretion of Aldosterone in the body, easily affect the normal metabolism of potassium ions, and induce the increase of blood potassium content.
• People taking Spironolactone: This drug is a Diuretic and a blood pressure lowering drug. It also keeps Aldosterone secretion, which is easy to lead to the rise of blood potassium.

According to statistics, about 1/7 of cardiovascular deaths in China can be attributed to high sodium intake, which means eating too much salt. Therefore, reducing sodium intake is necessary. For the sake of cardiovascular health,It is recommended to replace regular table salt with low sodium salt, and also eat less of the following three foods that can harm the cardiovascular system.

1. Eat less high salt foods

High salt foods not only include table salt, but also include what we eat on a daily basisSalted fish, bacon, bacon, pickled Chinese cabbage, etc. This type of food is high in salt. Excessive intake will break the balance of water and sodium in the body, induce retention of water and sodium, increase blood volume, and increase peripheral resistance of blood vessels,It can easily cause an increase in blood pressure and induce hypertension.

2. Eat less Free sugars

Free sugars is also known as added sugar, such as white granulated sugar, brown sugar, rock sugar and syrup. Excessive intake of these sugars can easily lead to an increase in blood sugar, which can damage endothelial cells and function over time, leading to hypertension and hyperglycemia.

3. Eat less high fat foods

High fat foods consumed in large quantities can increase levels of fat, triglycerides, and other substances in the blood, which is extremely detrimental to blood pressure control and can further worsen the condition.

Salt is a necessity in daily life, but it is not necessarily better to eat as much as possible. It is important to have a proper diet, otherwise it will pose a great threat to health. It is recommended to maintain a daily salt intake of 5g.
