Many studies in the past have already proven that our lifestyle is linked to cognitive decline, which occurs as a gradual decline in memory, attention and problem solving ability. This is alongside various medical conditions that may cause this. Given that diseases associated with cognitive decline such as dementia are irreversible and effective treatments are limited, prevention or early detection of the decline is critical.

A new study recently done in China found that our dietary habits may have a decisive influence on the chance that cognitive decline will occur in the future: high sodium intake (at least 5593.2 mg per day) and a high ratio of sodium to potassium (at least 3.8 per day) increased the risk of memory impairment in healthy elderly people The number of participants was 4213 no less than 50 years old, and the results are based on cognitive tests and self-reports of the participants.
However, it was found in the study that the consumption of potassium, the mineral found in salt, at certain levels (1653.3 mg per day), may additionally have a positive effect on the performance of cognitive tests among that population.
The researchers noted that the World Health Organization recommends a maximum of 1400 mg per day of sodium for people between the ages of 50 and 79 years, which is equivalent to 5 grams per day of salt, especially since high salt intake is usually accompanied by insufficient potassium intake, The equivalent of 1499.0 mg per day compared to the recommended level of 3600 mg per day.
