Watch out, any such meals in extra may be very dangerous in your stress

Salt, which consists almost entirely of sodium chloride, is necessary for the body to function. But be careful not to have too heavy a hand: it is used a lot in every kitchen, on every table and even in industrial preparations, and therefore it is likely to be consumed in excess. The National Food Safety Agency (ANSES) states that excessive salt consumption is recognized as one of the risk factors for high blood pressure and, therefore, for cardiovascular disease. That’s why the World Health Organization (WHO) recommends that adults consume no more than 5 grams (slightly less than a teaspoon) per day. Researchers at the University of Edinburgh give another, lesser-known reason for following this official recommendation: They found in a mouse study that a high-salt diet increased levels of a stress hormone by 75%.

In their study published in the journal cardiovascular research and funded by the British Heart Foundation and Kidney Research UK, these experts say they hope their early findings will encourage a review of public health policy around salt intake, with the aim of reducing the amount of salt in processed foods. They started from the observation that “ Although the effects on the heart and circulatory system have been well established, little is known about the impact of a high salt diet on a person’s behavior. To study this, the researchers used mice, which normally have a low-salt diet, and fed them high-salt foods to mirror typical human intake. They found that not only were resting stress hormone levels increased, but the mice’s hormonal response to environmental stress was twice that of mice that ate a normal diet.

“Foods high in salt alter our mental health”

Specifically, the study focuses on glucocorticoids (cortisol in humans, corticosterone in rodents such as mice), powerful hormones that support many important cardiovascular, cognitive, immune and metabolic cellular functions within the body. 🇧🇷 Glucocorticoids are not normally considered the main regulators of salt balance. However, observational studies in humans show a positive correlation between urinary free cortisol excretion and 24-hour sodium excretion, considered to reflect salt intake. », says the scientific team. She adds: a small number of controlled studies of sodium intake, usually lasting about 7 days, have examined the relationship between salt intake and urinary excretion of glucocorticoids. Ranging from 8 to over 600 subjects, these studies consistently report a direct relationship between dietary salt intake and urinary cortisol excretion.🇧🇷 🇧🇷

Cortisol is a well-known hormone, commonly referred to as the “stress hormone”. And it’s no wonder that the physical manifestations of stress are strongly linked to hormonal action and cortisol, secreted by the adrenal glands, regulates blood pressure, heart and immune functions and provides the brain with enough energy to prepare it to face stress. . But in the case of chronic stress, cortisol levels remain high and can upset the body’s balance. The researchers also found that salt consumption increased the activity of genes that produce proteins in the brain that control how the body responds to stress. Based on this observation, the latter claim that further studies are needed to confirm these initial results, but above all they insist on the importance of carrying out further scientific work to understand whether a high salt intake leads to other negative behavioral changes, such as anxiety or even aggression. .

🇧🇷 We are what we eat and understanding how foods high in salt affect our mental health is an important step towards improving well-being. We know that eating too much salt damages our heart, blood vessels and kidneys. This study now tells us that the high salt content in our food also changes the way our brain handles stress. concludes Matthew Bailey, Professor of Renal Physiology at the University of Edinburgh Cardiovascular Science Center and first author of the study. According to the medical journal Vidal, the French consume an average of between 9 and 10 g of salt per day, double the daily intake recommended by the WHO. Given current eating habits, ANSES considers that most salt consumed comes first from bread and toast, then cold cuts, condiments and sauces, cooked dishes, cheeses, soups and stews, as well as quiches and pizzas.
