Insects on the menu
Beetle juice and bug flour; Drs Ismari van der Merwe and Cariena Bothma are researching the possibility of a high-protein diet consisting of insect ingredients.

You’ve just had a tasty milkshake made from grasshopper juice, now for a light snack. Your choice: Salty cricket cookies or a deep-fried ant delight?

One of these days the above delicatessen may just find its way to your local restaurant menu if Drs Ismari van der Merwe, Cariena Bothma, both lecturers in the Department of Consumer Science, and their enthusiastic team of students have their way. Insects as food are rich in protein, often tasty, and having them on a menu is not as far-fetched as you may think. After all, we know what culinary delights mopani worms – and yes – cooked land snails (enjoyed as escargots) have become over the years.

 

Cricket smackerals

 

When Dr Van der Mewe explains the benefits of her team’s vision for a high-protein diet consisting of insect ingredients (cricket flour as an example), one becomes aware that this could be the solution to a myriad of problems. Insects eat much less than our regular menu items such as cows (beef), sheep (lamb chops) or pigs (pork). Insects as an alternative diet will reduce the negative impact that larger animals have on the environment and greenhouse gases. Insects have faster life cycles and it takes less effort and space to breed and feed them.

“Ugh! Ick! Disgusting,” you might think. But picture the taste lab where volunteers are given regular chocolate cookies made with regular flour, and then asked to compare it with cookies made from cricket flour. Dr van der Merwe assures me that most people will be unable to distinguish between them, often even preferring the cricket smackerals.

 

Heathy alternative

 

Insect breakfast cereals, granola, and snack food is a real and viable solution for the developing world where food is scarce, and hunger is a real issue. But is it healthy? Dr Van der Merwe assures me that during the process of ‘bug to flour’, they are addressing the main concern: micro-organisms that might be detrimental to health. Once the insects or processed insect by-products arrive on your plate, it’s a healthy high-protein alternative that might become the next revolutionary diet.

So, stand aside Atkins, beware Banting, and be gone Gluten-free – there is a new diet on its way to the menu. Brace yourself for beetle juice and bug flour: a diet full of proteins, fat, energy, and essential amino acids.

First doctorate in Thoracic Surgery in Africa awarded
2009-05-12

The University of the Free State (UFS) has become the first university in Africa to award a Ph.D. degree in Thoracic Surgery. The degree was conferred on Prof. Anthony Linegar from the university’s Department of Cardiothoracic Surgery during its recent graduation ceremony.

Thoracic surgery is a challenging subspecialty of cardiothoracic surgery. It began in South Africa in the 1940s and is a broad medico-surgical specialist discipline that involves the diagnosis, operative and peri-operative treatment of acquired and congenital non-cardiac ailments of the chest.

Prof. Linegar became the first academic to conduct a mixed methods analysis of this surgical specialty, which included a systematic review of all the research done in this field in South Africa. The title of his thesis is A Model for the Development of Thoracic Surgery in Central South Africa. The research was based on the hypothesis of a performance gap between the burden of disease in the community and the actual service provision. It makes use of systems theory and project management concepts to develop a model aimed at the development of thoracic surgery.

The research proved that there is a significant under provision of clinical services in thoracic surgery. This was quantified to a factor of 20 times less than should be the case, in diseases such as lung and oesophagus cancer. According to Prof. Linegar, there are multiple reasons for this. Listed amongst these reasons is the fact that thoracic surgery is not part of the undergraduate education in medical training. There tends to be a low level of awareness amongst clinicians as to what the thoracic surgeon offers their patients. The diagnostic and referral patterns in primary and secondary health facilities, where diseases must be picked up and referred early, are not functioning well in this regard. In addition, relatively few cardiothoracic surgeons express an interest in thoracic surgery.

Prof. Linegar’s model is named the ATLAS Mode, which is an acronym for the Advancement of Thoracic Surgery through Analysis and Strategic Planning. It includes the raising of awareness of the role of the specialist thoracic surgeon in the treatment of patients with thoracic diseases as part of the solution to the problem. Furthermore, it aims to develop an accessible and sustainable specialist service that adequately provides for the needs of the community, and that is appropriately represented in health administration circles.

His promoters were Prof. Gert van Zyl, Head of the School of Medicine at the UFS, Prof. Peter Goldstraw, from the Imperial College of London, United Kingdom (UK) and Prof. Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS.

Prof. Linegar has been with the UFS since 2004, is a graduate from Stellenbosch University in 1984 and completed his postgraduate training in Cardiothoracic Surgery at the University of Cape Town. He was granted a Fellowship in Thoracic Surgery at the Royal Brompton Hospital in London, UK and has since held consultant positions at the UFS, Stellenbosch University and in private practice. He has been involved in registrar training since returning from the UK in 1994 and has extensive experience in intensive care medicine. He has published widely, has presented papers at many international conferences, has been invited as a speaker on many occasions and has won awards for best presentation on three occasions.
