Taking salt substitutes may lower risk for heart disease, stroke

Published

on

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.

ANC: Why pregnant women with non-communicable diseases should register in teaching hospitals

By Francesca Hangeior

Maternal health experts have advised pregnant women with non-communicable diseases such as heart disease, hypertension, diabetes, and sickle cell disorder to register for antenatal care in teaching hospitals where they can get specialist care.

The gynaecologists noted that pregnancy among women with these health conditions was associated with high risk, especially during delivery, and therefore should be managed where there are specialists to avoid losing the baby or the mother or both.

The experts reiterated that pregnant women with those conditions needed to use tertiary hospitals for their ANC to reduce complications during and after birth.

A Consultant Obstetrician and Gynaecologist at the Nnamdi Azikiwe Teaching Hospital, Akwa, Anambra State, Dr. Stanley Egbogu, said pregnancy among women with co-morbidities comes with concern and lots of complications.

Egbogu said, “Women who have diseases like hypertension, diabetes, and heart disease before pregnancy must not use primary health centers for their antenatal care.

” It is important they register in a teaching or specialist hospital for their antenatal care because they need specialized care by experienced obstetricians and gynaecologists.

“If such women should visit PHCs for antenatal care, they should be referred to a teaching hospital immediately because they are prone to so many complications during pregnancy.”

The gynaecologist noted that people with hypertension could convulse during pregnancy.

“Those who have diabetes can have renal failure during pregnancy and delivery.

Those who have sickle cell disease can have anemia, and their blood can be so low that many of them have issues during delivery. For those who are asthmatic, pregnancy can worsen the asthmatic condition, and some of the drugs they use can affect the baby if not monitored.

“So, these women need specialised care and that cannot be offered at the primary healthcare level. The truth is that if those complications are not effectively managed, they could lead to the death of the woman or her baby”, he said.

Egbogu also advised the women to start antenatal care early and be regular at the antenatal clinic because “we want to see those that have problems more often than those that do not have problems.”

The Centres for Disease Control and Prevention says a woman with sickle cell disease is more likely to have problems during pregnancy that can affect her health and the health of the unborn baby than a woman without the disease.

During pregnancy, the disease can become more severe, and pain episodes can occur more often. A pregnant woman with SCD is at a higher risk of preterm labor, having a low birth weight baby, or other complications. However, with early prenatal care and careful monitoring throughout pregnancy, a woman with SCD can have a healthy pregnancy”, the CDC said.

According to the Asthma and Allergy Foundation of America, about 30 percent of all women with asthma report their asthma worsened while pregnant.

The foundation notes “Pregnant women with asthma may have a bit greater risk of delivering early. Or the infant may have a low birth weight. High blood pressure and a related condition known as pre-eclampsia are also more common in pregnant women with more severe asthma.”

Another maternal health expert and a Senior Registrar in the Obstetrics and Gynaecology Department at the Aminu Kano Teaching Hospital, Kano State, Dr. Mahmoud Magashi, says it is better and safer for pregnant women with co-morbidities to deliver in a specialist hospital to effectively manage associated risks both during and after delivery.

According to the World Health Organisation, in 2015, Nigeria’s estimated maternal mortality ratio was over 800 maternal deaths per 100,000 live births, with approximately 58,000 maternal deaths during that year.

But the Demographic and Health Survey 2018 showed that Nigeria’s latest maternal mortality ratio is 512 per 100,000 live births, which experts say is still very high.

Psychiatrists link Nigerians’ declining happiness to economic hardship

Published

By Francesca Hangeior

Psychiatrists have attributed Nigeria’s declining ranking in the World Happiness Report to worsening economic hardship, insecurity and political instability.

They warned that the rising cost of living and social instability was increasing anxiety, depression, and suicide rates among Nigerians, predicting a reduction in the country’s life expectancy rate.

The mental health experts who was speaking in an interview said that the inability of many citizens to afford necessities such as food, healthcare, and social interactions has significantly reduced happiness levels.

They noted that financial stress has prevented people from engaging in social activities that previously served as coping mechanisms, further worsening their emotional and mental well-being.

The experts urged the government to reverse the harsh economic situation and encouraged individuals to assist those in need and keep the hope alive.

On Thursday, March 20, the world marked the International Day of Happiness.

The Global Happiness Report released on Thursday by the Global Happiness Council ranked Nigeria 105th out of 147 countries.

The report evaluates happiness levels based on individuals’ assessments of their lives.

This year’s report showed that Nigeria, which used to rank the happiest African nation, now ranks 10th, dropping three steps from its usual position.

In 2003, the New Scientist magazine in the United Kingdom named Nigeria the happiest country in the world out of 65 countries surveyed.

In 2010, the Gallop World Poll also ranked Nigeria the happiest place on earth out of 53 countries surveyed.

Gradually, Nigeria’s rank began to drop as the years went by.

For example, before 2021, the World Happiness Report ranked Nigeria the sixth happiest country out of 155 countries.

But in 2024, the WHR placed Nigeria as the 102nd happiest nation out of 143 countries.

Speaking on the health and mental implications of the 2025 WHR, the President of the Association of Psychiatrists in Nigeria, Professor Taiwo Obindo, stated that the sad economic and socioeconomic realities of the country, insecurity situation and political difficulties were factors dwindling the happiness levels of many citizens.

He added that the lack of happiness could increase anxiety and depression levels, consequently causing a rise in death by suicide.

The don further noted that unhappy people were less likely to give their best at work or at home, leading to reduced economic output and a negative impact on the future of children in the country.

“The first question we need to ask ourselves is, what has driven us back, and then why we are where we are? What are the implications, is it the way and the manner in which things are going in the country? We are largely, generally, having difficulties economically, in terms of security, even politically. Things happening around us are not cheering.

“So, one won’t be too surprised that the cost of living is so high, the standard of living is so low, that people cannot afford to live a decent life,” Obindo said.

The APN president further stated that measures that previously helped Nigerians to socialise and be cheerful have become unaffordable, stating that these contributed to a drop in the country’s WHR.

The psychiatrist stated that a rise in unhappiness would lead to higher depression rates, which could, in turn, contribute to an increase in physical illnesses like high blood pressure.

“It affects virtually all parts of our body, all parts of our systems. And of course, those who are using one medication to control their blood pressure may need to do more. Of course, one of the things that I didn’t mention is that the costs of drugs have multiplied and a lot of people are not able to afford to buy some of the drugs for their medication. Therefore, situations are becoming more and more complicated.

“So, in all this, somebody who has hypertension and doesn’t have good control of it and needs more medication, because they cannot afford, may develop a stroke, may have a heart attack, and therefore, their life is cut short,” the don said.

The APN president further noted that the situation would reduce the life expectancy rate of Nigerians.

He warned, “It’s a vicious cycle and we need to have this reversed soon enough for people to go back to living their happy and their social life.”

Obindo urged the government to intervene and reverse the harsh economic situation to make life easy for Nigerians, stating that the high cost of things was becoming unbearable.

“At the community level, we must be our brother’s keeper. There are those who are more well-to-do, they must reach out, particularly in this particular season of fasting and lent. We must set up a good way of reaching out to people and the true less privileged around us.

“We must find a way of increasing job opportunities and making sure that the cost of living is reduced. We need to reverse the trend of pharmaceutical companies leaving the country.

“On the individual and family level, we must make sure that we don’t allow this situation to overwhelm us. We should make sure that we don’t allow our joy to disappear and be taken away by the situations around us. There is hope. Hope is what keeps us going. Things may not be as we expected now, but if we look and hope for a better tomorrow, that keeps us going,” the psychiatrist advised.

Also, a Consultant Psychiatrist, Dr Samuel Aladejare, emphasised the importance of happiness, explaining that when people are happy, the brain releases dopamine, a hormone that boosts motivation.

He noted that when dopamine was not released, it meant that there was sadness, adding that when sadness got to an extent, it led to depression, death by suicide and poor mental health outcomes.

The psychiatrist further stated that the inability to conveniently meet basic needs such as food, shelter and social connections has contributed to Nigeria’s declining WHR.

Aladejare also highlighted factors such as rising food prices, insecurity, kidnappings, and brutality from security agents, adding that the increasing migration rate has further impacted the social well-being of Nigerians.

The psychiatrist noted that countries that have maintained a top rank for a long time had robust social packages for their people, describing them as “one of the most secure countries in the world.”

He further noted that unhappiness could cause an inability to sleep, anxiety, and depression, leading to high blood pressure or worsening present health conditions.

Aladejare added that it could cause less concentration at work, leading to avoidable mistakes and frustration.

The mental health experts noted the inability of persons living with certain health conditions to afford their medications and treatment, would lead to poorer health outcomes and avoidable deaths.

Aladejare advised, “It would be good for Nigerians, now that we have this kind of situation, to prioritise their health. Prevention should rank high in everybody’s priorities and three measures are very important for preventing whatever illness it is, exercise, good sleep and proper diet. Those three things would save us a lot of issues.

“Yes, things are difficult but you can decide that whatever happens, you make time for exercise. 30 minutes in the morning or night or of more daily serious activities. Also, eating healthy. I know that has also become very difficult but try doing the least that we can do to make that happen. Despite how difficult it is, get adequate rest.”

He advised persons with non-communicable illnesses to adhere to their drug regimen to prevent further complications that required expensive interventions.

The mental health expert also advised avoiding negative news or social media posts and encouraged the use of good music to lighten the mood regardless of the situation.

Men who desire healthy children should marry before 40, expert advises

Men who wish to father healthy children have been advised to get married and start a family before the age of 40.

The President of the Nigerian Association of Urological Surgeons, Professor Nuhu Dakum, revealed that ageing negatively affects sperm quality, thereby increasing the chances of passing on genetic disorders to offspring.

“Sperm quality reduces with age. The count, motility, and morphology are all adversely affected. Also, there is an increase in damage to the sperm DNA, thus predisposing babies to genetic diseases,” he explained.

The consultant urologist further stated that while the age at which sperm quality varies, “generally it’s more significant from about 40 years of age.”

He attributed factors including “biological changes with age, lifestyle, e.g., smoking and alcohol, unhealthy nutrition, occupational exposure to toxins, etc.”

Dakum’s statement follows a recent viral conversation on X, formerly Twitter, that older men have weak sperm.

The tweet by Queen read, “Older men are more likely to give you children with genetic mutations like dwarfism, autism, Down syndrome, and schizophrenia.

“Their weak sperm has a higher risk of causing mutations in kids. Try your best not to have kids with their sperm.”

According to the Texas Fertility Centre, sperm quality and quantity decline over time, leading to age-related male infertility.

However, Healthline, a health portal, pointed out that sperm quality declines significantly in men over the age of 50, with factors such as sperm count and lifestyle habits being responsible for the deterioration.

Speaking further, Dakum stated that older men who desired to have healthy children could do so if they maintained good sperm health, noting that living healthily improves life generally and thus sperm health.

He added, “There may not be much to prevent it if the man is already old, but living healthy improves general and thus sperm health. However, genetic selection in the embryo or sperm checks for sperm damage can be done to reduce the chances, but these are expensive and not widely available. Donor sperm for such couples is also an alternative.”
