Omega-3 polyunsaturated fatty acid intake and plasma fatty acids of school going Indian children - a cross-sectional study.

Long-chain omega-3 polyunsaturated fatty acids (PUFA) such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) play an essential role in cognitive and behavioural changes among school going children. This study delineates the dietary omega-3 PUFA [alpha-Linolenic acid (ALA), DHA, and EPA] intake and plasma fatty acids levels among school-going children. This is a cross-sectional study purely observational in nature, wherein 625 apparently healthy boys and girls aged between 7 and 13 years were selected from five different schools of Hyderabad. Dietary information on omega-3 PUFA (ALA, DHA, and EPA) intake was collected using a food frequency questionnaire. Plasma fatty acid concentrations were measured in 34% of sub-sample using standard gas chromatography. The study revealed that the average dietary intakes of omega-3 PUFA, ALA, DHA, and EPA were 55.46, 15.82, 35.59, 4.06 mg/day, respectively. There was a significant difference in mean DHA intake among gender and age group [girls (38.64±1.45 mg/day), boys (31.80±1.38 mg/day) p < 0.001] and [7-10 years (31.75±1.38 mg/day), 11-13 years (38.07±1.40 mg/day) p < 0.01]. The mean plasma DHA and DPA levels of overall subjects were 0.98 nmol% and 0.18nmol% respectively which was comparable among different gender, age and BMI-for age groups. There was a positive correlation between dietary DHA intake and plasma DHA level [ρ=0.376 (p < 0.001)]. The current study demonstrated that the omega-3 PUFA intake in school going children was less and reinforces the importance of increasing the omega-3 PUFA intake through diet and supplements.

Effect of camel milk on glucose metabolism in adults with normal glucose tolerance and type 2 diabetes in Raica community: a crossover study.

BACKGROUND: To investigate effects of camel milk consumption on insulin sensitivity and glycemic control in normal and type-2 diabetics of Raika and Non-Raika community. METHODS: 28 raika and non-raika male were enrolled in study, categorized in 2 groups, non-diabetic and diabetic after one month stabilization. Non-diabetics were supplemented with cow milk and diabetics with camel milk; followed by one-month washout period. Afterwards regimen was interchanged for 3 months. Biochemical and anthropometric data was recorded at baseline, after stabilization, before and after washout and at end of study. RESULTS: An improving trend was observed in both the groups for camel milk effect (FBS 203.86 +/- 24.09 to 161.43 +/- 11.39 mg/dl; p<0.05, OGTT 320.86 +/- 25.34 to 213.79 +/- 15.96 mg/dl; p<0.05 in diabetics and FBS 101.79 +/- 3.06 to 96.79 +/- 2.56 mg/dl, OGTT 114.36 +/- 7.99 to 100.36 +/- 6.74 mg/dl in control). HbAlc improved due to camel milk consumption (8.39 +/- 0.64 to 7.27 +/- 0.67%) whereas deteriorated in the case of cow milk (7.36 +/- 0.66 to 8.26 +/- 0.60%) in diabetic group. The HOMA-IR reduced from 13.21 +/- 4.88 to 4.38 +/- 0.75, AUC-glucose from 37253.57 +/- 2859.08 to 30724.29 +/- 3677.33 and AUC-insulin from 5871.86 +/- 1210.73 to 3301.86 +/- 629.98 in the camel milk group. CONCLUSIONS: In type-2 diabetics camel milk reduces FBS, post-prandial glucose and HbA1c. AUC-insulin and AUC-glucose also decreased significantly along with HOMA-IR. It shows hypoglycemic effect of camel milk reducing insulin resistance. (www.actabiomedica.it).
