1. Evaluation of in-vivo total antioxidant capacity of black tea

Tea (Camellia sinensis) is, after water, the second most frequently consumed beverage in the world. Sri Lanka is one of the major producers of black tea in the world and a large proportion of the foreign exchange brought into the country is due to the tea industry. Several studies indicate that black tea consumption is associated with a reduced risk of degenerative diseases such as cardiovascular disease by reducing oxidation stress. Tea has a group of compounds known as flavanoids which exert antioxidant activity when tea is consumed. The ongoing study examines the elevation of total antioxidant capacity upon drinking tea.

2. Determination of association between plasma total antioxidant capacity and glycaemic control of type 2 diabetes patients
 
Association between the plasma antioxidant capacity and glycaemic control level will be determined along with serum insulin level, lipid parameters. Anthropometric variables, dietary and physical activity patterns will be assessed in type 2 diabetes patients, pre-diabetics, healthy people with strong family history of diabetes and normal healthy controls.

3.  Association between Infant and Young Child Feeding Practices and Anthropometric Indicators of Nutritional Status in Term Infants

Malnutrition has been responsible, directly or indirectly, for over 50% of the 10.6 million deaths annually among children under five years and over two-thirds of these deaths are often associated with inappropriate feeding practices, occur during the first year of life (WHO, 2006). Infant and young child feeding practices and its association with nutritional status are grey areas in nutrition field in Sri Lanka. This Prospective cohort study will be carried out to find out the association between infant and young child feeding practices and anthropometric indicators of nutritional status (Weight-for-length, Length-for-age, Weight-for-age, BMI-for-age, Mid-upper arm circumference for-age, Triceps skinfold-for-age, Subscapular skinfold-for-age) among term infants.

4. Calcium intake and bone mineral density (BMD) of adolescent schoolgirls and postmenopausal women.

Osteoporosis and bone fractures are mainly common in women and approximately one- third of women aged > 65 years suffer from vertebral osteoporosis. It has been shown that improving peak bone mass during adolescent period could delay or prevent osteoporosis in later life. Therefore World Health Organization recommends 1300 mg of calcium / day for the adolescent girls.

Adequate dietary intake and physical activity during adolescence are essential for the development of optimum peak bone mass.  However, only few dietary surveys have been conducted in Sri Lanka and their appropriateness is doubtful.

The aim of the proposed study is to assess Calcium intake and its association with bone mineral density among rural and urban adolescence girls and postmenopausal women.

5. Wayamba University on development of Household Food Security Index (HFSI) to assess the Household Food and nutrition security of the rural subsistence paddy farming sector in Sri Lanka

Food security, both at national and household level, is the most essential basic need to ensure the nutritional well-being of the people. The few research studies conducted in this regard, the outcomes of was not disseminated adequately. Interestingly, no major large-scale study on the household food security of rural subsistence farmers from both the socio-economic and biological carried out. This research intends to construct an appropriate Household Food Security Index (HFSI) that takes into account of different facets of the concept of food security to evaluate the level of household food security in Sri Lanka. Using HFSI the current status of household food security in the areas predominantly depends on subsistence agriculture in Sri Lanka will be assessed. Another objective is to identify and quantify the impact of various biological, social, and economical factors influencing food insecurity at the household level.  The outcome of the entire project would help to work out appropriate policies related to agriculture, in general, and food and nutrition, in particular, in Sri Lanka.
