How does salt affect fertility? – VnExpress

A diet high in salt can negatively impact fertility by damaging sperm in men and reducing follicle production in women.

Most of the things we eat and drink contain salt. Although the Food and Drug Administration (FDA) recommends that each person consume less than 2,300 milligrams of salt per day, controlling the amount of salt contained in food is difficult. In fact, the average American eats about 3,400 milligrams of salt each day.

Most people know that salt consumption has both benefits and harms to health. However, how salt affects fertility is something few people think about when eating chips or drinking salted caramel coffee.

A study by the University of Wyoming, USA and a study by Princess Nourah bint Abdulrahman University, Saudi Arabia, both showed that a diet too high in salt actually messes with the reproductive system.

According to lead researcher at the University of Wyoming, Dori Pitynski, high fat and salt intake has a negative impact on reproductive health.

“A high-fat diet is thought to accelerate puberty, but our work has demonstrated that mice fed a high-salt diet, even high-fat, will experience If you have children, you need to pay special attention to this as well, which means that not only does a high-salt diet delay puberty, but it can also lead to fertility problems later in life. life,” he said.

The scientists conducted two experiments, in which they fed a group of mice a high-salt diet and a group with no salt at all. Interestingly, both groups showed similar signs of delayed puberty. Therefore, it is not good to give up salt completely.

Sameh A. Abdelnour, lead researcher at Princess Nourah bint Abdulrahman University, conducted another study on the effects of salt on fertility in animals. Most animals are exposed to high levels of salt in their water and food. The study looked at how animals fed a high-salt diet respond to salt concentrations.

The results showed that there is a link between the consumption of foods containing high salt content and disorders, such as osteoporosis, obesity, cancer, hypertension, water retention, diabetes, high blood pressure, etc. Vascular dementia, cardiovascular disease, reduced gut health, decreased tissue function and autoimmune disorders. That’s because when you eat salty foods, salt changes the way your brain works and causes inflammation.

Salt is also believed to cause negative effects on development and reproductive function in both men and women by reducing hormone regulation (testosterone, FSH, LH and leptin). Research has specifically focused on how high salt levels affect sperm function, hormone regulation, testicular morphology, testicular weight loss, and abnormal hormonal regulation. The results of the study concluded that salt in high concentrations exposes sperm to oxidative stress and damage, reducing male fertility.

Meanwhile, in women, a high-salt diet reduces follicle production, reduces cell numbers, and induces apoptosis in granulosa cells. Therefore, salt not only negatively affects the body but also prevents the selection and development of ovarian follicles, increasing the possibility of infertility.

Salt also causes the placenta to become inflamed and leads to pregnancy complications by causing disruptions in the transport of nutrients to the fetus.

To limit the harmful effects of salt, nutritionist Gina Keatley recommends that people be careful with processed foods. A simple way to limit sodium is to cook your own meals with fresh ingredients and use spices and herbs to enhance flavor without adding salt. Potassium can be used to offset the sodium in a meal, so try to eat plenty of green vegetables and beans.

However, dietitian Alissa Rumsey, a spokeswoman for the American Academy of Nutrition and Dietetics, also advises not to cut too much salt in the diet. “Too little salt can cause many of the same harmful effects as eating too much salt. Studies have shown increased mortality, increased blood pressure and increased risk of cardiovascular disease from eating too little salt,” she said. talk to Yahoo Health.
