On 26 March 2020, the President declared a national lockdown in response to the COVID-19 pandemic as it started to emerge in South Africa. Since then and several weeks into the lockdown, Statistics South Africa (2020) has provided evidence which many intuitively knew would be more devastating to households than the coronavirus itself – loss of income and the negative effects that follow hunger. Stats SA reported that the percentage of respondents receiving no income increased from 5,2% before the lockdown to 15,4% by the sixth week of the national lockdown. Given that the majority of South Africans depend on the informal labour market, such as informal traders and casual workers, this lack of income would hit millions of households. Furthermore, Stats SA also reported a decrease in formal wage/salary earners for the same period, from 76,6% before the national lockdown to 66,7% by the sixth week of national lockdown.

While South Africa is food secure at national level, millions of households are food insecure. According to the United Nations Food and Agriculture Organization’s (FAO) 1996 definition of food security, this simply means that there is not enough food at all times for all the people in a household to have physical and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life.  In short, people are hungry and at greater risk for ill health – physically, emotionally, and spiritually.  A hungry man is an angry man. Likewise, a hungry nation is an angry nation.

In July 2019, the measurement of extreme poverty – the food poverty line (FPL) – was raised to R561 (using April 2019 prices) per person per month, which was up from R547 last year. This is the amount of money that Stats SA calculates an individual requires “to afford the minimum required daily energy intake” of 2 100 calories per day. Before the onset of the COVID-19 pandemic, South Africa already had a precarious food and nutrition situation, especially for young children. South Africa’s child stunting levels – an indication of chronic and long-term food insecurity – increased from 21% in 2008 to 27% in 2016.  With COVID-19 and the subsequent lockdown, child malnutrition rates are expected to increase. Stunting not only affects a child’s health, making them more susceptible to disease and infection, but also impairs their mental and physical development – meaning that children who suffer from stunting are less likely to achieve their full height and cognitive potentials as adults.  

What can we do to address this food situation or prevent it from worsening?
The 2020 Global Nutrition Report recognises and asserts that inequality and globalisation are major drivers of food insecurity. As individuals and as collectives, we need to continue to advocate for and support calls to continue raising the child support grant to help households stay above the poverty line.  Millions of households in South Africa are supported by social grants; in solidarity, we need to appreciate the safety net that these social grants provide to vulnerable households. Advocate for and support initiatives to safeguard child health and nutrition, including efforts to promote, protect, and support breastfeeding in neonatal care, postnatal care, and ongoing support to breastfeeding mothers.  Breastfeeding remains the most cost-effective health intervention for infants and young children, supporting optimal growth and development and providing long-term health benefits into adulthood. Advocate for and support initiatives to coordinate sustainable food support to vulnerable households, including, among others, food distribution, food vouchers, onsite feeding, home gardening, and tax-free food baskets.  These efforts would be our collective solidarity to support and protect vulnerable households as we enter the global economic recession as a result of COVID-19.

How can we protect our households’ food and nutrition security? 
COVID-19 brings with it much uncertainty and many unintended negative effects.  While we seek out strategies to support mental well-being and emotional resilience, we also need to remain physically healthy.  Good nutrition is fundamental to good health and well-being. South Africa has a set of ten healthy eating guidelines that promote the principles of eating more unprocessed foods, eating more vegetables and fruit, reducing the use of fats and oils and reducing the intake of sugar and salt.  Good nutrition starts with good food and sometimes good food can cost more, so it is important to use your food budget wisely.  The food budget includes food eaten at home, as well as funds spent on food eaten outside of the home, eating take-outs, foods bought online, and food eaten away from home.  Planning your meals in advance and sticking to a food plan will limit opportunities to spend money on items that are not on the plan; planning ahead also means you can take advantage of good prices, especially as food prices are on the increase and will continue to increase. Bulking up when prices are low and on special, making use of combo buying, e.g. buy three and pay for two, and buying directly from food producers such as co-ops, all help to save money in the long run.  Meat, fish, and especially seafood are the most expensive food items; rather use eggs, chicken, and less expense meat cuts for your meals.  Legumes such as dried beans, peas, and soya are less expensive with great nutritional value.  Explore these less-known group of foods with many great health benefits, such as no fat, more fibre, and lots of vitamins and minerals.

In an effort to eat more fresh vegetables and fruit, starting a home garden is a great family challenge and a definite way of keeping food costs low. And as we navigate the new normal post-COVID times ahead, let us keep mealtimes and meal preparation a fun family activity. Discovering new foods and new tastes can be as exciting as travelling to a new place.  Stay safe, stay healthy!

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.
