Despite the considerable increase in population in many of these countries, food production per capita in 1988-90 was significantly higher as compared to 1979-81 figures, the increase being specially marked in such countries as Vietnam, Cambodia, Indonesia, and Malaysia. Available daily calorie supply was adequate to meet the requirement. The overall pattern of food production however has shown little change, with cereal production continuing to account for a predominant part of food production. There is no evidence of a significant uptrend with respect to production of pulses, milk, horticultural products, poultry or meat production in most countries.A uniquc and unfortunate feature of the nutrition situation in South-Asian countries is that the incidence of low birth weight deliveries is as high as 34% (1990), ranging from 25% in Sri Lanka to 50% in Bangladesh (as against less than 7% in the countries of Europe and North America). Even in countries of Africa where the overall food and nutrition situation is worse than in South Asia, the incidence is well below 20%. This is a reflection of the poor state of maternal nutrition in pregnancy.Florid nutritional deficiency diseases have shown a steep decline over the last two decades, but goitre and iron deficiency anaemia continue to be major public health problems, though some headway has been made with regard to the control of the former. Severe forms of growth retardation in children have declined but the majority suffer from mild and moderate forms of growth retardation.Countries of the Region are in varying stages of developmental transition. Among the burgeoning middle classes in some of these countries there are evidences of escalation of degenerative diseases such as diabetes and coronary heart disease.

Not only does increased biodiversity contribute to nutrient production and consumption, but it acts as a safeguard against food shortages due to pests and diseases by spreading the risk. Biodiversity can improve dietary diversity in such a way to ultimately contribute to improved food and nutrition security. As a result biodiversity is often highlighted in global discussions related to food and nutrition security. Potatoes (Solanum tuberosum L.) are highly biodiverse food crops, with more than 4000 different cultivars grown globally. The crop is sometimes considered as part of the vegetable component of food baskets, but it is mainly added to meals as a starch because potatoes have a high starch content and are thus high in energy. However, significant differences in the nutritional content (including micronutrient composition) of different potato cultivars have been reported in many countries. It is therefore proposed that specific cultivars could potentially contribute more to critical nutrients required in the diet of countries at risk of malnutrition. The nutritional profile (macronutrients and minerals) of 11 potato cultivars cultivated in sub-Saharan Africa was determined and the contribution which these different potatoes could make to the diet, and consequently to food and nutrition security, is discussed. The results showed that significant differences are found in the nutritional content between the different cultivars. Significant differences (p < 0.001) were found in macronutrients such as protein and fat as well as micronutrients such as copper, phosphorus and potassium. These results indicate the potentially beneficial role which a biodiverse range of crops such as potatoes, could play in the food and nutrition security of developing countries.展开更多

After the substitution, the highest protein content was observed in PDBM (1.78 ± 0.12)% followed by PSBM, (1.35 ± 0.01)% and the lowest was in the control (0.91 ± 0.55)%. Moreover, cookies fortified with date palm powder increased the carbohydrate and fat contents compared to the control and significantly increased the calorific value of PDBM. The formulated cookies were significantly higher (p < 0.05) in iron (39.95 ± 3.00) mg/100 g and zinc (13.65 ± 1.61) mg/100 g in PDBM compared to other cookies. The date palm powder incorporated in cookies significantly increases the darkening of biscuits during cooking. The organoleptic characteristics of PDBM and PSBM were rated overall best when specific parameters were tested. With the shortage of wheat and importation constraints, an alternative provides a great market opportunity for local products like potatoes and beans. In addition, fortifying food products as cookies eaten by all will contribute to a more food and nutrition-secured world.展开更多
