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.

Fighting the tuberculosis battle as a collective
2015-09-28



The team hard at work making South Africa a
healthier place

Tuberculosis (TB) is second only to HIV/AIDS as the greatest killer worldwide due to a single infectious agent. More than 95% of TB deaths occur in low- and middle-income countries. Despite being more prevalent among men than women, TB remains one of the top five causes of death amongst women between the ages of 15 and 44 years. While everyone is at risk for contracting TB, those most at risk include children under the age of five and the elderly. In addition, research indicates that individuals with compromised immune systems, household contacts with pulmonary TB patients, and healthcare workers are also at increased risk for contracting TB.

According to the Deputy Director of the Centre for Health Systems Research and Development (CHSR&D) at the UFS, Dr Michelle Engelbrecht, research has found that healthcare workers may be three times more likely to be infected by TB than the general population.

The unsettling fact

“Research done in health facilities in South Africa has found that nurses do not often participate in basic prevention acts, such as opening windows and wearing respirators when attending to infectious TB patients,” she explained. 

In response to this concern, CHSR&D, which operates within the Faculty of Humanities at the the University of the Free State (UFS) Bloemfontein Campus has developed a research project to investigate TB prevention and infection control in primary healthcare facilities and households in Mangaung Metropolitan.

Action to counter the statistics

A team of four researchers and eight field workers from CHSR&D are in the process of gathering baseline data from the 41 primary healthcare facilities in Mangaung. The baseline comprises a facility assessment conducted with the TB nurse, and observations at each of the facilities. Individual interviews are also conducted with community caregivers, as well as TB and general patients. Self-administered questionnaires on knowledge, attitudes, and practices about TB infection control are completed by all nurses and facility-based community caregivers.

Healthcare workers are the main focus of this research, given their increased risk of acquiring TB in healthcare settings. At clinics, interventions will be developed to improve infection control practices by both healthcare workers and patients. TB patients’ households are also visited to screen household contacts for TB. Those found to have symptoms suggesting TB infection are referred to the clinics for further assessment and treatment.

The findings of this study will serve to inform the development of an intervention to address TB prevention and infection control in primary healthcare facilities. Further funding will be sought to implement and evaluate the intervention.

Curbing future infections and subsequent deaths as a result of TB is the priority for the UFS. The cooperation and collaboration of the community, government, and sponsors will ensure that this project is a success, hence prolonging life expectancy.
