Taking salt substitutes may lower risk for heart disease, stroke
Nutritionists and cardiovascular experts have warned against high sodium (salt) intake due to its ability to increase blood pressure, the danger it poses to cardiovascular health and its ability to predispose people to noncommunicable diseases.
They, however, recommend the consumption of potassium salt substitutes instead of dietary salt (sodium chloride) to reduce such risks.
According to them, sodium and chloride in salt can cause an expansion of the extracellular fluid volume, which over time, causes a rise in blood pressure that results in strokes, heart failure, heart attacks, and kidney disease.
While calling for the replacement of sodium chloride with salty-tasting potassium chloride, experts said decreasing dietary salt intake from the current global levels of 9–12 grams per day to the recommended level of less than 5 grams per day would have a major impact on blood pressure and cardiovascular disease.
The professionals said that salt reduction strategies are best in the prevention of global noncommunicable diseases and can avert over yearly 2.5 million deaths from heart attacks and strokes.
According to the World Health Organisation, potassium salt substitutes are alternatives to regular salt both as an ingredient of pre-packaged foods and as salt added to food and beverages by consumers.
The WHO noted that the use of potassium salt substitutes also known as low-sodium salt substitutes is increasingly being considered as a potential blood pressure-lowering strategy by national health authorities and public health organisations.
“The amount of dietary salt consumed is an important determinant of blood pressure levels and of hypertension and overall cardiovascular risk. Annually, 17.5 million deaths are attributable to cardiovascular disease, which accounts for an estimated 31 per cent of deaths globally.
“It is also estimated that one out of every 10 cardiovascular deaths are attributable to salt intake of more than 5g per day,” the United Nations agency added.
Speaking exclusively with PUNCH Healthwise a Registered Dietitian Nutritionist, Olusola Malomo said dietary salt is essential to the body, but its high intake can also raise blood pressure, which can damage the body in many ways.
He said high blood pressure has been linked to heart disease, stroke, kidney failure, and other health-related problems, adding that potassium salt substitute provides a seasoning alternative for manufacturers looking for how to reduce sodium.
He added, “Potassium has many important functions. It allows the nerves to respond to stimulation and muscles to contract, including those in the heart. It reduces the effect of sodium in table salt on blood pressure.
“It helps to move nutrients into cells, and waste products out of cells. Salt substitutes made from potassium chloride alone look like regular salt and have a salty flavour, but have zero sodium.
“However, potassium doesn’t activate the same taste cells as sodium. That’s why people complain that these substitutes often leave a bitter or metallic aftertaste. Salt substitutes contain potassium chloride, either alone or mixed with regular salt.”
Malomo added that potassium salt is less processed than table salt and retains trace minerals, which add flavour and colour, insisting that sea salt is also available as fine grains or crystals and is often promoted as being healthier than table salt.
On its impact on cardiovascular health, a Consultant Cardiologist at the Lagos University Teaching Hospital, Idi-Araba, Dr Akinsanya Olusegun-Joseph, said the human body needs a small quantity of salt for optimal health and development but too much of it causes the body to retain water.
“This increase in fluid in the body increases blood pressure, which puts a strain on blood vessels, the heart and kidneys. With this, people with high blood pressure have an increased risk of coming down with heart disease and stroke.
“It’s, therefore, safe to say that everyone should pay attention to and reduce their dietary salt intake. Potassium salt is available in Nigeria and we recommend it to some patients. A lot of people don’t know the quantity of salt they consume daily.
“Too much sodium and the accompanying fluid retention in the body can be very dangerous. But potassium has a way of dilating the vessels and by doing this, the blood pressure will be reduced. The spiral resistance reduces and blood pressure comes down.
“Sodium causes retention of fluid but potassium doesn’t. Potassium will reduce high blood pressure but sodium will increase it. So, potassium salt substitutes have a greater advantage when compared with sodium chloride.”
Buttressing this position, a study published in the National Library of Medicine titled, ‘Potential use of salt substitutes to reduce blood pressure’,’ by Clare Farrand and her team, affirmed that higher intakes of potassium are associated with decreased blood pressure independent of sodium intake.
The study also suggested that increased consumption of potassium can mitigate the negative effects of high sodium consumption on blood pressure, indicating that the sodium‐potassium ratio of the diet is therefore a major determinant of blood pressure.
“Both sodium and chloride in salt lead to an increase in blood pressure and then cause strokes, heart failure, and heart attacks, as well as kidney disease,” the study stated.
The authors recommended a reduction in sodium use in food manufacturing and processing, and to explore the use of potassium‐based sodium replacers.
“Further consideration may need to be given to how best to label salt substitutes (namely potassium) in processed foods to ensure that people who may be adversely impacted are aware,” the study recommended.

Edo confirms eight Lassa fever deaths, 56 cases
Edo has recorded 56 Lassa fever cases and eight deaths between Dec. 30, 2024 and January 2025, says the Commissioner for Health, Dr Cyril Oshiomhole.
Oshiomhole confirmed the incident on Friday in Benin while formally declaring the situation of Lassa fever in the state.
“The 2025 epidemic year began on Dec. 30, 2024. Since then, 336 suspected cases have been reported, with 56 confirmed and eight resulting in death,” he said.
He said the outbreak posed significant public health risks due to its rapid transmission potentials and severe outcomes if not effectively managed.
Oshiomhole revealed that 14 patients are currently receiving specialised care at the Lassa Fever Treatment Center in Irrua Specialist Teaching Hospital (ISTH).
He also noted that “In 2024, the state recorded 3,270 suspected cases, 292 confirmed cases, and 41 deaths, showing a decline from 2023 which recorded 65 deaths from 372 confirmed cases.”
According to him, the state has activated its Public Health Emergencies Response Management Team, collaborating with healthcare facilities, community leaders, and stakeholders to contain the outbreak.
As part of the response, measures include “enhanced surveillance, expanded treatment centers, Infection Prevention and Control (IPC), public awareness campaigns, and partnerships with health organisations.”
He urged residents to report anyone with symptoms like fever, weakness, headaches, vomiting, or bleeding to the nearest health facility for early detection.
The commissioner also tasked the response team to reduce the Case Fatality Rate (CFR) and assured of government support to enhance Lassa fever management efforts.
He further said the molecular laboratory at UBTH had been optimised for Lassa fever testing, increasing the state’s capacity with two testing centers at UBTH and ISTH.
The News Agency of Nigeria (NAN) reports that Dr Ekaete Tobi of ISTH has been appointed as the state Lassa fever Incident Manager to coordinate outbreak control activities.

NAFDAC Seals Kaduna Warehouse Over N75 Million Expired Goods
The National Agency for Food and Drug Administration and Control (NAFDAC) recently sealed a warehouse in Kaduna for storing expired food and cosmetic products valued at over N75 million.
The agency announced the development on its official X handle, identifying the warehouse’s location as PP2A Bayajidda Street by Kano Road, New Ogbomosho Road. The operation was prompted by a tip-off from a concerned citizen, leading to a raid by NAFDAC enforcement officers.
During the operation, workers were caught repackaging expired biscuits into sacks. Other expired items, including dairy milk, vegetable oil, soft drinks, and detergents, were also uncovered, underscoring the severity of the malpractice.
The warehouse’s managing director was apprehended for interrogation. NAFDAC assured the public that strict regulatory actions would follow the investigation to deter others from engaging in similar illegal practices.
The agency encouraged citizens to remain vigilant and promptly report any suspicious activities or products to the nearest NAFDAC office, emphasizing the importance of public cooperation in ensuring safety standards.
In a related development, NAFDAC recently shut down a pharmacy on Onitsha Crescent, Area 11 – Garki, Abuja, for selling expired and unregistered drugs. Among the discoveries were expired products worth over N7 million, including “H-Pylori” test kits, which pose significant health risks. The pharmacy’s Managing Director and Superintendent Pharmacist were arrested as part of the investigation.
Since November 2024, NAFDAC has established comprehensive guidelines for the handling and disposal of unwholesome products. These include food, medicines, medical devices, and cosmetics. The agency has reiterated that no regulated product can be manufactured, imported, exported, sold, or used in Nigeria without proper registration.
Unwholesome products, as defined by NAFDAC, include items that are expired, counterfeit, substandard, improperly stored, incorrectly labeled, or unauthorized. Facilities are required to maintain an inventory of such products and follow disposal guidelines to ensure compliance.
NAFDAC’s Director-General, Prof. Mojisola Adeyeye, has emphasized the agency’s commitment to upholding safety and quality standards. She highlighted that enforcing best practices, ensuring supply chain integrity, and monitoring regulated products remain core pillars in safeguarding public health and fulfilling NAFDAC’s mandate.
Through these efforts, NAFDAC continues to prioritize the health and well-being of Nigerians while sending a strong message to perpetrators of such illicit activities.

Cholera kills nine in Rivers
The Rivers State Government yesterday confirmed the death of nine persons in two local government areas from an outbreak of cholera.
Commissioner for Health, Dr Adaeze Oreh, who spoke in Port Harcourt yesterday, said three died in Andoni while six casualties were recorded in Akuku-Toru
She said the death occurred from 41 suspected cases in the two councils but noted that the government through the Ministry of Health had put measures in place to halt the disease.
Oreh said: “With the deepest sense of sympathy to victims of a suspected outbreak of acute watery diarrhoea caused by suspected cholera outbreak, because we, at the Ministry of Health, are yet to actually confirm that those deaths were from Cholera in Isiodun community of Andoni Local Government Area of Rivers State.
“However, the symptoms of the cases reported are in keeping with the surveillance case definition of cholera.
“Cholera is an acute diarrhoea disease that is caused by the bacteria ‘vibrio cholerae’. It thrives in areas with poor water, sanitation and hygiene wash infrastructure.
“It is transmitted by drinking water that is contaminated or ingesting contaminated food as well as contact with surfaces that have been contaminated from infected persons”
She added: “As at the 13th of January, 2025 we have recorded a total of 41 suspected cases from two local government areas in the state. And those local governments are Andoni and Akuku-Toru.
“We have also recorded nine associated deaths out of which three are from Andoni. Six were confirmed from Akuku-Toru Local Government Area.
“It was majorly these deaths that were reported and brought to our attention that necessitates the quick response from our directorate of public health and Disease Control.
