Liver health under the microscope as World Hepatitis Day nears
As World Hepatitis Day approaches on July 28, the spotlight falls on the importance of liver health and the role of nutrition in preventing liver disease.
Experts are urging South Africans to pay closer attention to what they eat, especially as poor dietary habits, excessive alcohol intake, and undiagnosed infections - such as hepatitis B and C - continue to threaten public health.
Murray Hewlett, CEO of Affinity Health, emphasises that the liver, often overlooked in daily health discussions, performs over 500 vital functions and plays an essential role in maintaining overall health.
' The liver is one of the body's hardest working organs, but also one of the most overlooked when it comes to everyday care,' says Hewlett.
He also cautions that poor dietary choices, excessive alcohol consumption, and undiagnosed infections, such as hepatitis B and C, can lead to long-term liver damage.
The foods we choose to consume can have profound effects on liver health. While some foods promote the liver's ability to repair itself and function optimally, others can lead to inflammation and fat accumulation, potentially culminating in serious health issues. Leafy greens: Spinach, kale, and Swiss chard are packed with antioxidants and assist the liver in flushing out toxins.

According to the World Health Organization, hepatitis B and C cause more than 1.1 million deaths globally each year, with chronic hepatitis B affecting an estimated 3.5 million South Africans—many unaware of their condition. Liver disease is often a silent threat, surfacing only at advanced stages when treatment options may be limited.
However, there is a silver lining. Early screening, coupled with a commitment to a healthy lifestyle and better nutrition, can significantly reduce the risk of severe liver complications, including cancer and cirrhosis.
The liver is an incredible organ boasting a remarkable ability to regenerate, but it requires diligent care. By making informed dietary choices, reducing alcohol intake, and scheduling regular medical check-ups, individuals can protect their liver health for life.

NWU TRACTOR rally makes appearance in Klerksdorp
The North-West University's (NWU) TRACTOR rally aimed at shining a light on the emotional, social, and financial impact of dementia and Alzheimer's disease in South Africa, held a trail run in Klerksdorp on July 19. The run was organised as precursor to the campaign which will run from August 30 to September 12 and will span several provinces. At each stop, communities will engage in awareness and support events designed to educate, connect, and inspire. TRACTOR stands for 'Together Rallying Across Communities To Overcome Remembrance-loss.' At the heart of the campaign is a symbolic tractor, decorated to represent memory, resilience, and hope. The vehicle serves as a metaphor for the slow but determined journey many families face as they care for loved ones suffering from memory loss. The campaign's unique and creative approach sets the stage for meaningful conversations and lasting impact in both rural and urban communities. The TRACTOR Awareness Rally aims to raise awareness about the growing prevalence of dementia, educate the public on health and caregiving resources, and combat the stigma surrounding memory-related conditions. With over 187,000 South Africans over the age of 60 currently living with dementia—and estimates suggesting that this number could rise to 250,000 by 2030—the need for awareness, education, and support has never been more urgent. Families affected by dementia often endure emotional strain and financial difficulties, while caregivers face isolation, burnout, and a lack of formal support systems. This campaign seeks to offer relief through knowledge, connection, and public dialogue. The NWU staff and students are playing a vital role in the campaign. Student volunteers will help with logistics, venue preparation, and local programme coordination throughout the rally. The campaign will also contribute to ongoing academic research by gathering data, conducting interviews, and documenting personal stories that provide insight into the lived experiences of caregivers and affected families. The campaign will have a strong digital footprint, including livestreamed sessions and regular updates across social media platforms under the hashtag #TRACTORforMemory. Mini replica tractors will be distributed along the route as keepsakes, symbolising remembrance and community solidarity. These tokens aim to serve as lasting reminders of the importance of empathy and collective support in the face of memory loss.

South Africans living longer: Here's the life expectancy rate in 2025
While life expectancy is projected to increase, South Africans are having fewer children. Should we be worried? South Africans are living longer, with the national life expectancy now 12 years more than it was at the turn of the century. The continued rise in life expectancy is thanks to advances in healthcare, HIV prevention, and overall living conditions. According to Statistics South Africa's (Stats SA) 2025 mid-year population estimates, life expectancy at birth is now 64 years for males and 69 years for females. This marks a recovery from the setbacks of recent years, including a major dip during the Covid-19 pandemic and continued health impacts of HIV and AIDS. Life expectancy has improved In 2002, males had an average life expectancy of 52 years, while females averaged 57 years. This year's figures reflect a notable improvement, especially among men. Life expectancy for both sexes declined sharply between 2020 and 2021 due to the Covid-19 pandemic. In just one year, males saw a 3-year drop in life expectancy (from 62.8 to 59.8), while females experienced a 3.6-year decline (from 68.8 to 65.2). Although the pandemic had a devastating impact, Stats SA notes that life expectancy began to recover steadily from 2022. 'Life expectancy at birth in South Africa improved by 1.9 years for males (61.7 years) and 2.2 years for females (67.4 years) in 2022,' it said. As public health programmes expand and treatment coverage improves, particularly among women of reproductive age, the country's long-term outlook continues to stabilise. Progress in healthcare has also resulted in major improvements in child survival. The infant mortality rate (IMR) has declined from 61.9 deaths per 1 000 live births in 2002 to 23.1 in 2025. 'Similarly, the under-five mortality rate (U5MR) declined from 79.9 child deaths per 1 000 live births to 26.1 child deaths per 1 000 live births between 2002 and 2025,' Stats SA noted. The decline in child mortality is attributed to better maternal and child health services, expanded immunisation coverage, and reduced HIV transmission from mother to child. These advances mean that more children are surviving into adolescence, even as fewer are being born. ALSO READ: Why SA has 32.9% unemployment and Zimbabwe 8% Fewer births South Africa's total fertility rate (TFR) has, however, fallen steadily over the last two decades, following global trends. In 2008, the rate stood at 2.78 children per woman. By 2025, it had dropped to 2.21, according to Stats SA's estimates. This is worryingly close to, but still above, the replacement fertility rate of 2.1. 'More rural provinces of Limpopo and Eastern Cape indicate higher total fertility rates, whilst more urbanised provinces such as Gauteng and the Western Cape indicate lower rates of fertility,' Stats SA found. South Africa has one of the lowest fertility levels on the continent, with a study on fertility and childbearing in South Africa noting the extent of the decline. 'Fertility in South Africa declined from an average of 6 to 7 children per woman in the 1950s to an average of 4 to 5 children in the 1980s and about 3.3 children per woman in the mid-1990s'. Among the factors for the decline are delayed marriage, the desire for smaller families or economic challenges, improved healthcare and living conditions, contraceptives, and access to education. Pretoria-based obstetrician and gynaecologist Dr Rogers Mmabatswa told The Citizen that many of his patients said they had decided on smaller families because of the rising cost of living. 'Many complain about the cost of raising their children. Food, clothing, and schooling are expensive. So, for a lot of people, there are financial considerations when deciding whether to have a child, or another.' Should SA be worried? A 2024 study by the economic policymaking institute, Centre for Economic Policy Research, outlined the economic dangers of a low birth rate. 'The challenge of low fertility is magnified by the fact that it causes older-age population shares to swell. Population ageing may naturally hamper economic activity insofar as older people impose significant burdens associated with public expenditures on health and long-term care and economic security and tend to work less than their younger counterparts.' However, Mmabatswa says smaller families that come from reduced birth rates may have positives. 'Parents and caregivers are able to dedicate more time and energy to their children, giving them increased individual attention than if there were many other children vying for their attention. 'This will often translate to better performance at school, sport, or socially.' NOW READ: Are you employed if you work an hour a week? Stats SA says yes

Liver cancer to double worldwide, most of it preventable, reveals study
PARIS - The number of people with liver cancer will nearly double worldwide by 2050 unless more is done to address preventable causes such as obesity, alcohol consumption and hepatitis, a study warned Tuesday. New cases of liver cancer -- the sixth most common form of the disease -- will rise to 1.52 million a year from 870,000 if current trends continue, according to data from the Global Cancer Observatory published in the Lancet medical journal. It is also the third deadliest of all cancers, with the study predicting it would take 1.37 million lives by the middle of the century. However three out of five cases of liver cancer could be prevented, the international team of experts said. The risk factors are drinking alcohol, viral hepatitis and a build-up of fat in the liver linked to obesity called MASLD, which was previously known as non-alcoholic fatty liver disease. The viruses that cause hepatitis B and C are expected to remain the leading causes of liver cancer in 2050, according to the study, published on World Hepatitis Day. Vaccination at birth is the best way to prevent hepatitis B, but vaccine coverage remains low in poorer countries including in sub-Saharan Africa, the study said. Unless vaccination rates are increased, hepatitis B is expected to kill 17 million people between 2015 and 2030, it added. Alcohol consumption is estimated to cause more than 21 percent of all cases of liver cancer by 2050, up more than two percentage points from 2022. Cancer due to obesity-linked fat in livers will rise to 11 percent, also up more than two percentage points, the researchers calculated. The large-scale study, which reviewed the available evidence on the subject, underscored "the urgent need for global action" on liver cancer, the authors said. The experts called for more public awareness about the preventable danger of liver cancer, particularly by warning people with obesity or diabetes about fatty-liver disease in the United States, Europe and Asia.
