Image: Association
between mean sodium, potassium, sodium/potassium, and salt intake and self-reported memory.
Model 1 was adjusted
for age, sex, place of residence, area of residence, education level, work status, marital status, level of physical activity, smoking and drinking habits.
Model 2 adjusted for energy, carbohydrate, protein, and fat intake based on Model 1 (potassium intake adjusted for the sodium model and sodium intake for the potassium model).
Model 3 adjusted BMI, sleep duration, cardiovascular and cerebrovascular disease, and baseline cognitive test scores
based on Model 2.

Dementia can impair a patient's memory, thinking and decision-making skills, which can affect their daily activities
.
The disease has become one of the leading causes of
death and disability among older people worldwide.
China is not only the country with the largest elderly population, but also one of the fastest aging countries, Alzheimer's disease has brought huge economic, health and social challenges
to China.
Dementia is irreversible and the lack of effective treatments makes prevention and early detection of age-related cognitive function essential
.
Studies have found that some lifestyle choices are associated with cognitive function; For example, physical activity, diet, and sleep
.
However, the effects of dietary sodium and potassium on cognitive function have not been studied
in detail.
In a prospective study published in the KeAi journal Global Transformation, a team of researchers from China looked at the effects
of dietary sodium, potassium, sodium-to-potassium ratio, and salt on cognitive function in a group of older adults in China.
The number of participants was 4213 and they were at least 50 years
old at baseline.
The results were based on cognitive tests and participants' self-reports
.
The team found that high sodium intake (5593.
2 mg/day) and high sodium-potassium ratio (3.
8 mg/day) increased the risk of
memory impairment in older adults.
Conversely, higher levels of potassium intake (> 1653.
3 mg/day) were associated with higher cognitive scores; When the sodium intake of 1000 mg/day was replaced with the same amount of potassium intake, the average cognitive test score (13.
44 at baseline, total score of 27.
00) improved by about 1 point
.
In addition, the researchers demonstrated that the effects of dietary sodium, sodium-potassium ratio, and potassium on cognitive function may be mediated by cardiovascular and cerebrovascular diseases (CCVDs), while the link between salt and cognitive function can be mediated
by sleep.
Despite more than a decade of trying to limit salt and sodium in people's diets, sodium intake in Chinese mouths remains alarmingly high, exceeding the recommendations of many other countries and the World Health Organization that people aged 50-79 should consume no more than 1,400 mg/day of sodium and 5 grams/day of salt.
This high salt intake is usually accompanied by inadequate potassium intake (1499.
0 mg/day in this study) vs
.
The recommended intake in China is 3600 mg/day).
The results of this study also confirm previous findings that dietary sodium-potassium ratios can better measure how these elements affect cognitive function, rather than looking at sodium or potassium values
alone.
Corresponding author Zhao Ai added: "Based on our findings, we have reason to believe that reducing sodium intake and appropriately increasing potassium intake is beneficial to cognitive function
.
Given our findings, as well as the nutritional status of Chinese, it will be important
for future research to focus on determining the optimal ratio of sodium and potassium in the diet of older adults.
In addition, developing strategies to increase the ratio of sodium and potassium in Chinese diets should be a priority

", which may affect the work
covered in this article.
