Calcium Intake among Myanmar Residing in Bago, Kayin, and Yangon Areas

A cross-sectional survey combined with 24-hour dietary recall and food diary was undertaken to assess the calcium intake of the Myanmar population. The study was conducted from November 2003 to October 2005. A total of 886 subjects of both sexes aged above 2 years from three States and Divisions (Bago, Kayin, and Yangon) of Myanmar were included in the study. The major measures were mean daily calcium intake (mg/day) and major sources of calcium in the diet. Overall mean calcium intake was 197+13mg/day (2-9 years), 421+2mg/day (10-19 years), 399+21 mg/day (20-49 years), and 383+25mg/day (>50 years) for males, while the corresponding values for females were 207+17 mg/day, 366+19 mg/day, 387+16 mg/day, and 327 +19 mg/day. Calcium intake was less than 80% of the recommended dietary allowances (RDA) for Myanmar for ages 2-9 years and 10-29 years in all the study areas, and for the 50 years and above age group in Yangon. Fish paste was found to be the major source of calcium. Milk and milk products contributed very little to total calcium intake, contributing 2.1% for residents in Yangon, 5.1% in Pa-an and none in Bago. Consumption of calciumrich foods, particularly milk and milk products, should be encouraged among the Myanmar people. Towards this end, appropriate nutrition education materials should be developed for promotional purposes.

Glycaemic indices if three commonly eaten varieties of Myanmar Banana

In order to provide information for the nutritional management of diabetes mellitus, glycaemic indices (GI) of three varieties of banana commonly eaten in Myanmar were determined using twelve healty women volunteers with normalglucose tolerance. After an 8-10 hour overnight fast, the subjects consumed one kind of selected banana in amount equivalent to 50 g available carbohydrate portion {~ three and a half pieces of Phee-Kyan (189 g); ~four and a half pieces of Rakhine (165 g)~~ three pieces of Thee-hmwe (yellow) (192 g)}. After a week interval, GI was determined for another kind of banana. Venous blood samples were collected and immediately analyzed for plasma glucose by glucose oxidase method.GIs of Myanmar bananas (mean -+ S.E.M) were 51.7 -+ 7.69 percent for Rakhine, 55.29 -+ 5.66 for Phee-Kyan and 63.73 -+ 8.46 for Thee-hmwe (yellow). They were lower than GI of commonly eaten Myanmar rice, Pawsun. Banana also contains vitamins A and C which were not provided by cooked polished rice. Furthermore, banana hasa higher calcium and fibre content. Therefore, all three varieties of Myanamr banana can be recommended as a source of complex carbohydrate with low or moderateGI for diabetic diet

The effect of oral iodized oil on the breast milk iodine content

The effect of oral iodized oil administration on the breast milk iodine concentrations was studied at different stages of lactation in two groups of women, one control and the other, experimental group. A single dose of iodized oil contraining 400 mg iodine was given orally to each woman of experimental group during the third trimester of pregnancy. Casual urine samples before dosing and breast milk samples after parturition were collected. 37.5 percent of the subjects had low urinary iodine excretion (ie. less than 50 ug per gram creatinine). In the control group, milk iodine concentrations were low compared to Western data. Breast milk iodine concentrations were significantly higher in the experimental group, as compared to the control group up to six months postpartum. A greater part of iodine was found to be secreted in the colostrum and in most cases, milk iodine concentrations declined towards six months postpartum. The present study indicates that oral iodized oil containing 400 mg iodine given during the third trimester of pregnancy can effectively provide adequate iodine in the breast milk for the infants for the first six months.
