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!

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
