    Healthy young adults with borderline diets showed mild upper intestinal changes, including increased anaerobic bacteria and nutrient losses. These findings suggest potential impacts on nutrient absorption even without overt illness.

    Area of Science:

    • Human Nutrition
    • Gastroenterology
    • Microbiology

    Background:

    • Nutritional status and gut health are crucial for overall well-being.
    • Subtle dietary inadequacies may impact gastrointestinal function.
    • Understanding the gut microbiome's role in nutrient absorption is essential.

    Purpose of the Study:

    • To evaluate the nutritional status and gastrointestinal health of young adults with potentially borderline diets.
    • To investigate the relationship between diet, small intestinal morphology, bacterial presence, and nutrient absorption.

    Main Methods:

    • Nutritional assessment, blood chemistry, and fecal pathogen screening in 43 healthy males.
    • In-depth analysis in 10 subjects: duodenal histology, bacterial cultures, disaccharidase activity, glucose absorption, and fecal fat/nitrogen excretion.

    Main Results:

    • No overt malnutrition or illness detected initially.
    • Mild small intestinal morphological changes observed.
    • Increased anaerobic bacteria in the upper intestine.
    • Decreased glucose transport and elevated fecal nitrogen losses.

    Conclusions:

    • Borderline nutritional quality diets may lead to subtle but significant gastrointestinal alterations.
    • These changes, including altered gut microbiota and impaired nutrient absorption, can affect individuals with suboptimal diets.
