A decade ago, Rob Nixon, a professor in the humanities and environment studies at Princeton University in the US, introduced the concept of slow violence in the context of climate change and environmentalism, explaining slow violence as violence that occurs gradually and out of sight, a violence of delayed destruction that is dispersed across time and space, an attritional violence that is typically not viewed as violence, at all. While profound, Professor Nixon’s concept of ”out-of-sight violence” and ”violence of delayed destruction” was challenged by Professor Thom Davies from the University of Nottingham in the UK who urged scholars to instead ask the question: ”out of sight to whom?” He argued that structural inequality mutated into noxious instances of immediate slow but pervasive violence by those who have endured toxic landscapes and unhealthy physical environments.

Reflecting on the impact of COVID-19 in the context of persistent hunger in South Africa’s cities, Dr Gareth Haysom from the University of Cape Town, challenged us as society to recognise the ”slow violence“ of hunger and food insecurity that are also often “experienced in private, incremental and accretive ways that are often invisible”. But as urged by Professor Davies, the question of child hunger and malnutrition in South Africa is really, to whom is this hunger and malnutrition invisible?

Malnutrition and its debilitating consequences have been studied and known about as far back as the 1950s. In 1976, Stoch and Smyth from the then Child Psychiatric Unit and Department of Paediatrics and Child Health at the University of Cape Town reported on a 15-year developmental study conducted from 1955 to 1970 on the effects of severe undernutrition during infancy on subsequent physical growth and intellectual functioning on coloured children from the Cape Flats concluded that the effects of severe undernutrition during infancy on subsequent brain growth and intellectual development confirmed gross retardation of intellect in the undernourished group when compared to the controls. Furthermore, the study concluded that given the abnormal performance of the control group that there was much evidence to suggest that the controls were also suboptimal in terms of nutritional status and intellectual functioning. This means that in general the nutritional status of coloured children on the Cape Flats was poor. Fast forward to 2021, and child nutrition in South Africa is still sub-optimal.

South Africa’s nutrition indicators have worsened

The most recent data from 2016 National Demographic Health Survey showed that 27% of children under the age of five years are stunted or too short for their age. This equates to more than 1.5 million children whose health and development is compromised and who have a lower chance of reaching their full potential even into their adult years. While many countries of the same economic development status have improved their nutrition indicators, South Africa’s nutrition indicators have worsened. South Africa has been identified as one of the countries with high levels of multiple forms of malnutrition manifested in high levels of stunting, childhood obesity and multiple micronutrient deficiencies, the most notable being vitamin A deficiency. These multiple forms of malnutrition cast a long shadow of ill-health and delayed development. of children, robbing them of quality of life and years of life in their childhood and their adult years. Malnutrition has a double cost on quality of life and additional health costs consuming resources that could have been spent on better food.

The right to have access to sufficient food is embedded in Section 26 and 27 of our Constitution and the right to adequate nutrition for children is stipulated in section 28. The Bill of Rights enshrined in the Constitution states that “every citizen has a right to have access to sufficient food, water and social security” and that “the State must take reasonable legislative and other measures, within its available resources, to achieve the progressive realisation of this right”. Before the onslaught of COVID-19, we as health and social care professionals, have been acutely aware that a significant number of South Africans do not have access to sufficient food and go hungry on a daily basis. Malnutrition is well-documented in South Africa and unfortunately is progressively getting worse.

SA has not prioritised children or the realisation of their human rights to food and nutrition

Better nutrition can only be achieved when food and care are available to young children but in the context of rising food prices, limited maternal support and a difficult psychosocial environment, mothers are not able to provide their children with a health-enabling environment. Our high levels of stunting and obesity levels reflect the chronic situation of poor-quality and inadequate diets coupled with poor caring practices. While these poor dietary practices are often individualised and focused on mothers, there are many systemic and structural barriers for families to access affordable and nutritious diets. The food environment is shaped by a profit-centred food system that comes at the cost of people’s health and well-being. Children have always being the prime focus of the food industry, from the promotion of maternal supplements to improved maternal nutrition for the developing foetus, to the promotion of infant formula as a convenient and easy-to-use alternative to breastfeeding, to the manipulative marketing of foods for and to children.

Child nutrition has become a global tracking indicator for both human and economic development. Sadly, our lack of progress over the past 20 years clearly illustrates that we, as a country, have not prioritised children or the realisation of their human rights to food and nutrition. The findings of the 2020 Child Gauge gives us, as a country, the opportunity to stop the violations of children’s rights and to end the slow violence of child malnutrition.

Link between champagne bubbles and the UFS?

What is the link between the bubbles in champagne and breakthrough research being done at the Mayo Clinic in America? Nano research being done at our university.

Prof. Lodewyk Kock of Biotechnology says a human being consists of millions of minute cells that are invisible to the eye. The nano technology team at the UFS have developed a technique that allows researchers to look into such a cell, as well as other microorganisms. In this way, they can get an idea of what the cell’s “insides” look like.

The UFS team – consisting of Profs. Kock, Hendrik Swart (Physics), Pieter van Wyk (Centre for Microscopy), as well as Dr Chantel Swart (Biotechnology), Dr Carlien Pohl (Biotechnology) and Liza Coetsee (Physics) – were amazed to see that the inside of cells consist of a maze of small tunnels or blisters. Each tunnel is about 100 and more nanometres in diameter – about one ten thousandth of a millimetre – that weaves through the cells in a maze.

It was also found that these tunnels are the “lungs” of the cells. Academics doing research on yeast have had to sit up and take notice of the research being done at the UFS – to the extent that these “lungs” will appear on the front page of the highly acclaimed FEMS Yeast Research for all of 2013.

The Mayo Clinic, in particular, now wants to work with the UFS to study cancer cells in more detail in order to fight this disease, says Prof. Kock. The National Cancer Institute of America has also shown interest. This new nano technology for biology can assist in the study and development of nano medicine that can be used in the treatment of cancer and other life threatening diseases. Nano medicine uses nano metal participles that are up to one billionth of a metre in size.

Prof. Kock says laboratory tests indicate that nano medicine can improve the efficacy of anti-cancer medicine, which makes the treatment less toxic. “According to the Mayo Clinic team, nano particles are considered as a gold cartridge which is being fired directly at a cancer tumour. This is compared to fine shot that spreads through the body and also attacks healthy cells.”

“This accuracy implies that the chemotherapy dose can be lowered with fewer side effects. The Mayo Clinic found that one-tenth of the normal dosage is more effective against pancreas cancer in this way than the full dosage with a linkage to nano particles. According to the clinic, this nano medicine could also delay the spread of cancer,” says Prof. Kock.

The nano particles are used as messengers that convey anti-cancer treatment to cancer cells, where it then selectively kills the cancer cells. The transport and transfer of these medicines with regard to gold nano particles can be traced with the UFS’s nano technology to collect more information, especially where it works on the cell.

“With the new nano technology of the UFS, it is possible to do nano surgery on the cells by slicing the cells in nanometre thin slices while the working of the nano medicine is studied. In this way, it can be established if the nano medicine penetrates the cells or if it is only associated with the tiny tunnels,” says Prof. Kock.

And in champagne the small “lungs” are responsible for the bubbles. The same applies to beer and with this discovery a whole new reach field opens for scientists.
