Randomised controlled trials of healthy individuals show that the effect of reduced dietary salt intake (SR) on blood pressure (BP) is less than 1 mmHg. Still, health authorities use BP effects obtained in studies of participants with high BP to simulate reduced mortality in computer modeling studies. These simulations are in contrast to real data from observational studies, which show that a low salt intake is associated with an increased mortality of about 15% in healthy as well as in hypertensive individuals. Consequently, SR at the population level should not be a public health priority.

The effects of salt reduction and adequate nutrition intake among older adults with physical frailty remain controversial. Therefore, the present study investigated whether the association between daily salt intake and blood pressure among community-dwelling older adults, including the very old people, based on their physical frailty status. This cross-sectional study used data from the SONIC study, a cohort study on older adults, collected between 2010 and 2012.

Cardiovascular disease (CVDs) is the leading cause of mortality worldwide. Corporate workplaces have been identified as important environmental factors that can increase the risk and severity of CVDs. Evidence indicates that the risk and severity of CVDs can be effectively reduced by mitigating modifiable behavioural and intermediate risk factors.

This population-based, nationally representative cross-sectional study assessed the daily salt consumption status and its associated cardiovascular disease (CVD) risk factors using weighted data from the STEPwise approach to noncommunicable disease risk factor surveillance conducted in 2018 in Bangladesh. It included a non-institutionalized adults' population of 6189 men and women aged 18-69 years. Their daily salt consumption was estimated using the spot urine sodium concentration following the Tanaka equation and reported according to the standard nomenclature proposed by the World Hypertension League and partner organizations involved in dietary salt reduction.

Although long-term high dietary sodium consumption often aggravates hypertension and bone loss, sodium in the intestinal lumen has been known to promote absorption of nutrients and other ions, e.g., glucose and calcium.

Intense thirst can lead to uncontrolled fluid intake, resulting in congestion and frequent readmissions. Many predictors of thirst were identified, but little research addressed its association with salt intake.
