Opinion article by Dr Chantell Witten, Division of Health Professions Education, University of the Free State.


World Breastfeeding Week is celebrated every year from 1-7 August. In South Africa, it coincides with Women’s Month and gives us the opportunity to reflect on how far we have come and how far we still have to go to achieve gender equity in different spheres of life. Even more reason for us in the academic sphere to stop and think about the areas of support that may still need attention and effort to correct.

In the context of protecting breastfeeding this would speak to the Code of Good Conduct in the Labour Act which affords pregnant and breastfeeding women protection and support. In extreme cases it means protection from exposure to hazardous substances, but in the general setting of the work environment this relates to workplace support for a private and safe place to express breastmilk. One institution made headlines when a staff member was secretly videoed while she was expressing breastmilk. What is also needed is to put in place a policy that guides on how university property such as a fridge may or may not be used to store expressed breastmilk, or how to deal with a manager who insists on holding meetings in a woman’s scheduled milk-expressing time slots. The law may indicate that you are entitled to two 30-minute time slots to express but it is quite another issue to get your colleagues to accommodate or respect your biological needs.

Protecting breastfeeding 

Besides the protection of employees, the government in its commitment to improve child health and nutrition has committed to protect breastfeeding from the undue influence of the infant-formula industry by implementing the recommendations of the International Code for the Marketing of Breastmilk Substitutes. South Africa approved the Regulations Relating to Foodstuff for Infants and Young Children (R991) to control the marketing and promotion of infant formula by limiting how the product may be marketed and how the industry may engage with the public and child health and development professionals, in particular. 

While many are aware of the prohibition to advertise or to promote and distribute free or incentivised sales of infant formula, many may not be aware of the limitations placed on academics and researchers. The academic and research fraternity has had a long and conflicted relationship and history with the infant-formula industry. Many departments and individual researchers have received funding, conference sponsorship and gifts from the infant-formula industry. In the early 2000s at the height of the HIV epidemic, the Department of Health recommended that women living with HIV should not breastfeed and instead provided six months of free formula milk, inadvertently implying that health professionals approved of infant formula. While the national Department of Health has since stopped the distribution of free infant formula through the programme for the prevention of mother-to-child transmission of HIV (PMTCT) from 2011, many health professionals trained in the early years continue giving mixed messages to mothers and display limited skills to promote and support breastfeeding.

So how do we protect breastfeeding in the academic setting? 
As more women enter academia, managers and the institutional leadership need to be cognisant and purposeful in developing a breastfeeding culture by granting women the protections afforded them by the Labour Law. Furthermore, in all spheres of academia and research, and as an institution, we need to guard against conflict of interest and conflicted relationships with the infant-formula industry. We need to do due diligence by raising the awareness of R991. All child health and development professionals should be acquainted with R991 through their curricula, and we should individually and collectively be accountable in our conduct to protect, promote and support breastfeeding as a human right, an investment in health and development, and for a sustainable future. There can be no greater dividend than to invest in optimal nutrition for infants and our children. They are the future.

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
