As we celebrate our heritage it is important that we look at our heritage not only as an opportunity to wear our traditional attire, recite our clan praises and eat our traditional food. We need to also to look at our indigenous knowledge and apply it to our reality.
Currently climate change effects on human health are potentially increasing with varied impact. Expected increases in the frequency, intensity and duration of extreme weather events are likely to result in unprecedented impacts on public health. Impacts are likely to be greatest in the developing countries such as South Africa. Besides nutrition, climate change also threatens the global economy.
Indigenous or traditional food has been abandoned for a western diet that is known to have a high prevalence of non-communicable diseases and uses up a lot of health care budget. The so called ”western diet” is rich in fat and low in carbohydrates and fibre. A good example is a burger: it contains 28g protein; fat 19g; saturated fat 9g; sugar 6g; sodium 910mg; carbohydrates 33g.
Indigenous foods such as amarula, calabash, leafy vegetables etc should not only be celebrated on heritage day, but should be part of our diet every day. For example amarula fruit (Sclerocarya birrea) is rich in ascorbic acid potassium, calcium and magnesium. The seed contains a nut with antioxidants and oleic acid, palmitic acid, myristic acid and stearic acid and proteins rich in amino acid glutamate and arginine. All these are vital for human health. Pumpkin leaves are rich in vitamin B6 (pyridoxine) which is essential for brain development in children.
Our communities are neglecting the importance of traditional diet intake and suffer from the negative effects of junk food. The cultural beliefs and everyday practices of families have a powerful influence on the diet choices of youth.
The ongoing nutritional transition in South Africa has made people more vulnerable to non- communicable diseases such as stroke, coronary heart diseases, physical inactivity, hypertension, and diabetes mellitus. Increase in obesity and overweight has been associated with this issue found in adults and stunting and underweight in young children.
Heritage month should also aims to explore the significance of indigenous lifestyles to improve the status of our national health. The capacity of amaranth leafy vegetables are to be used in addition or substitution of the agricultural produced food as a tool to fight food insecurity in South Africa.
