| Abstract:
Hunger and malnutrition are found in many areas of South Africa, with an estimated 3 million people under the age of 15 suffering from malnutrition. Vegetables are of great importance in helping to alleviate this problem, as they remain the cheapest source of important protein, vitamins, minerals and essential amino acids in the diet of many communities. A number of the basic needs of rural people are met by the use of indigenous plants. Traditional food plants add to food security and provide dietary supplements to the staple foods in regions with low agricultural potential or during periods of drought. The nutritional value of indigenous vegetables are compared to that of "exotic" vegetables. From a nutritional point of view Protein, Vitamin A, calcium and iron are of importance, since they are lacking in the diet of many people in South Africa. Comparisons are made on the basis of the RDA for a 14 to 18 year old male of each of the nutrients provided by a 100 g portion. The medicinal value of these crops are an important element in the traditional health care system in both rural and urban areas, with more than 80% of people in Soweto still consulting traditional healers. This implies a tremendous demand for indigenous medicinal plants. Indigenous plants should therefore be protected as a source of both food and medicine. The importance of traditionally used plants as vegetable crops, their uses and their medicinal value are discussed. | |
