We examined dietary fiber intake, food sources of dietary fiber, and relation of dietary fiber to body composition and metabolic parameters in college students with plausible dietary reports. ⋯ Inclusion of implausible dietary reports may result in spurious or weakened diet-health associations. Dietary fiber is negatively associated with fasting insulin levels in men and women and consistently associated with adiposity measurements in men.

Randomized Controlled Trial
Effect on immune indices of preoperative intravenous glutamine dipeptide supplementation in malnourished abdominal surgery patients in the preoperative and postoperative periods.
To determine if parenteral glutamine dipeptide supplementation given only in the preoperative period in malnourished patients after gastrointestinal surgery would sustain its effects into the first postoperative week, as shown by immune indices. ⋯ Parenteral glutamine supplementation in the preoperative period resulted in increased white blood cell, granulocyte, and lymphocyte counts, which was not sustained in the first week of the postoperative period, when supplementation was discontinued before surgery.
