Protein-energy malnutrition still impacts children’s growth and development. We investigated the prolonged effects of egg supplementation on growth and microbiota in primary school children. For this study, 8–14-year-old students (51.5% F) in six rural schools in Thailand were randomly assigned into three groups: (1) whole egg (WE), consuming 10 additional eggs/week (n = 238) (n = 238); (2) protein substitute (PS), consuming yolk-free egg substitutes equivalent to 10 eggs/week (n = 200); and (3) control group (C, (n = 197)). The outcomes were measured at week 0, 14, and 35. At the baseline, 17% of the students were underweight, 18% were stunted, and 13% were wasted. At week 35, compared to the C group the weight and height difference increased significantly in the WE group (3.6 ± 23.5 kg, p < 0.001; 5.1 ± 23.2 cm, p < 0.001). No significant differences in weight or height were observed between the PS and C groups. Significant decreases in atherogenic lipoproteins were observed in the WE, but not in PS group. HDL-cholesterol tended to increase in the WE group (0.02 ± 0.59 mmol/L, ns). The bacterial diversity was similar among the groups. The relative abundance of Bifidobacterium increased by 1.28-fold in the WE group compared to the baseline and differential abundance analysis which indicated that Lachnospira increased and Varibaculum decreased significantly. In conclusion, prolonged whole egg supplementation is an effective intervention to improve growth, nutritional biomarkers, and gut microbiota with unaltered adverse effects on blood lipoproteins.
Background Food frequency questionnaires (FFQ) are a useful dietary assessment tool to determine relationships between diet and non-communicable diseases (NCDs). Our purpose was to validate a semiquantitative FFQ (semi-FFQ) for Thais at risk of metabolic syndrome (MS). Methods The researchers identified 345 men and women aged 30–65 years who were eligible for the study. Ninety-four participants were finally enrolled (54 in a “urine-collection not-required” group and 40 in a “urine collection” group). They were asked to maintain a 4-day food record for 4 weeks and partook in a semi-FFQ interview during week 4. Urine samples and biochemical results related to MS were collected. Validation results were associated with three primary nutrients for MS (sugar, fat, and sodium) and biochemical results (blood glucose, lipid profiles, blood pressure, and 24-h urine sodium). Results The biomarker level of each key MS nutrient significantly increased commensurate with rises in semi-FFQ estimated intakes. Correlation coefficients (r) were as follows: fasting blood glucose, r = 0.221 (fruits) and r = 0.229 (desserts); triglycerides, r = 0.112 (a la carte-dishes); low-density lipoprotein cholesterol, r = 0.205 (rice-with-topping dishes); systolic blood pressure, r = 0.272 (snacks) and r = 0.190 (a la carte dishes). Fasting blood glucose was a significant biomarker associated with the development of metabolic syndrome (OR 1.42, 95% CI 1.12–1.81). We also found that fat (OR 1.28, 95% CI 1.09–1.89), sodium (OR 1.98, 95% CI 1.05–1.95) and energy (OR 1.09, 95% CI 1.01–1.17) from an a la carte meal were significantly associated with the development of metabolic syndrome. Conclusions Thai food has a unique characteristic since it often pairs various ingredients and seasoning in one menu. This semi-FFQ is a tool that offers relatively valid ranking for intake of energy, nutrients, single foods, and mixed dishes based on Thai menus associated with a risk for developing metabolic syndrome and NCDs. Using this tool could help identify unhealthy dietary patterns and help develop recommendations for people at risk with the goal of preventing NCDs.
Objectives We aimed to determine long-term effects of egg supplementation on growth, blood lipoproteins, blood proteins, nutritional status, and microbiota in primary school children. Methods A randomized controlled, cluster study was performed at 6 rural schools in Central, Eastern, and Western Thailand. 635 students (8–14 years old) were recruited into the study. Subjects were randomly assigned into 3 groups, based on weight for age: 1) Whole eggs (WE) - consume 10 additional eggs per week [n = 238] 2) Egg substitute (ES) - consume yolk-free egg substitute equivalent to 10 eggs per week [n = 200], and 3) control group (C, [n = 197]). The anthropometric, biochemical indexes, dietary intake, and microbiota were measured at week 0 (baseline), week 13–14, and week 34–35. Results At baseline, 14% were under-weighed, 9% were stunted, and 16% were wasted. At 34–35 weeks, the increases in body weight and height were higher in WE group than those in C group (3.56 ± 0.93 kg, P < 0.001 and 5.11 ± 0.92 cm, P < 0.001). No significant differences in weight and height were observed between the ES and C groups. Prealbumin levels were higher (1.53 ± 0.33 mg/dL, P < 0.001) in WE but not ES as compared with C. There were significant decreases in total cholesterol, triglycerides, and LDL cholesterol in WE but not ES as compared with C. Additionally, HDL cholesterol tended to increase in WE (0.66 ± 0.99 mg/dL, ns) as compared with C. Bacterial diversity in WE, ES and C group was not significantly change neither alpha nor beta diversity. After whole egg supplementation, the overall relative abundance of the Bifidobacterium was increased up to 1.28-fold. The differential abundance analysis also indicated that Lachnospira significantly increased and Varibaculum significantly decreased after whole egg supplementation. Conclusions Long-term whole egg supplementation significantly enhanced growth in young children with no adverse effect on blood cholesterol levels. The result coincided with promoting health-benefit gut bacteria. However, further insight into the mechanistic effect of egg consumption on gut microbiota and growth is needed.
