Estimates of dietary intake of nutrients have many problems, and confirmation of these estimates by chemical measurements of excretory products helps to establish their validity. The correlation between urinary amino acid excretion and dietary history of protein intake are reported herein. Diet diaries were kept by and 24-h urine collected from participants in the Trial of Antihypertensive Therapy and Management, a multicenter cooperative trial comparing the effects of drugs and diet on blood pressure control, side effects, and quality of life. The nutritional information was coded and the data stored by the nutritional analyses facility at Albert Einstein College of Medicine. The chemical determinations were done in the laboratories of the Department of Pathology, Izumo, Japan. The correlation between total protein and 3-methylhistidine was r = 0.42 (n = 96). The correlation was similar for animal protein (r = 0.4). These correlations are of the same order of magnitude as those between dietary sodium and urine sodium, and dietary potassium and urine potassium. We conclude that measurement of urinary protein excretion products may be a useful way to estimate dietary protein intake.

Introduction: Optimising the micronutrient status of women before and during reproduction confers benefits to them and their offspring. Antenatal multiple micronutrient supplements (MMS), given as a daily tablet with nutrients at ~1 recommended dietary allowance (RDA) or adequate intake (AI) reduces adverse birth outcomes. However, at this dosage, MMS may not fully address micronutrient deficiencies in settings with chronically inadequate diets and infection.

This study aimed to examine the relationship between eating behavior, nutritional status and mental health. It is a cross-sectional study conducted on a sample of 360 healthy individuals aged 19-64 years. The General Health Questionnaire (GHQ-12) was used to evaluate mental health and the Three-Factor Eating Scale (TFEQ-R21) was used to assess eating behavior.

Aim: This study aimed to evaluate the relationship between sleep quality, hedonic hunger, and adherence to the Mediterranean Diet (MD) in early adolescents and to investigate if hedonic hunger would mediate the influence of sleep quality on adherence to the MD.
Method: A total of 786 middle school students (boys, 51%) aged 10-14 years were included in the study. A self-administered questionnaire was used to collect data.

Probiotics effectively alleviate host diarrhoea, but the specific mechanism is not clear. Therefore, we explored the protective mechanism of Bacillus coagulans (BC) on intestinal barrier injury induced by Klebsiella pneumoniae (K. pneumoniae) in rabbits by HE, immunofluorescence and 16S rRNA.

Ovalbumin (OVA) is a high-risk allergen with complex tertiary structure in food samples. Here, we developed an accurate UPLC-MS/MS-based assay to improve OVA quantitative performance in processed foods. Full-length isotope-labeled OVA proteins (OVA-I) were synthesized using stable isotope labeling by amino acids in cell culture (SILAC) technique and employed as functional internal standards to ensure similar cleavage sites between internal standards and analytes.
