The common reasons for limiting salt intake often revolve around salt’s effects on the cardiovascular system, obesity and non-communicable diseases. However, researchers in Japan have now concluded that high salt intake can also lead to an increase in a key biomarker associated with Alzheimer’s disease and other biomarkers associated with the symptoms of dementia.

When it comes to sodium intake among adults, the general consensus is that high consumption will increase risk of hypertension and stroke. According to the 2020–2025 Dietary Guideline for Americans, 45% of people 18 and older are living with hypertension.

The Food and Drug Administration (FDA) can help setting and finalizing longer term voluntary sodium reduction targets for different food categories, according to a petition filed with the agency by the nonprofit Center for Science in the Public Interest. Reducing sodium in the food supply could save tens of thousands of lives and tens of billions of dollars in healthcare costs each year. 

Females tend to like salt more than males. Like many sex-related differences, the proclivity for salt likely relates to the physiological need to retain sodium and the fluid following sodium, sufficient to sustain another life in pregnancy. A new study confirms that hypertension caused by salt sensitivity was higher among females than among males.

A Korean-based study has found a link between depression and a higher intake of ultra-processed food (UPF) among the female population. Females who consumed the highest measured level of UPF have a 1.51 times higher likelihood of suffering depression than those following a diet high in fruits and vegetables and lower in saturated fat, sugar content and dietary sodium levels, researchers discovered. 

The World Health Organization (WHO) Global report on sodium intake reduction shows that the world is off-track to achieve its global target of reducing sodium intake by 30% by 2025. Only 5% of WHO Member States are protected by mandatory and comprehensive sodium reduction policies and 73% of WHO Member States lack full range of implementation of such policies.

In 2021, IFBA (International Food & Beverage Alliance) members collectively developed a global sodium reduction commitment with standardized, stepwise voluntary targets for key categories of products to be achieved incrementally by 2025 and 2030. The following chart illustrates IFBA members’ commitments and achievements to reduce sodium in their product portfolios.
