Fortified bread may help control blood sugar and boost metabolism
NCT ID NCT03836495
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding the nutrients phosphorus and lysine to white bread could improve how the body handles blood sugar and energy use after eating. Sixteen healthy adults ate different fortified breads, and researchers measured their blood sugar, insulin, and energy expenditure. The goal was to see if this simple dietary change could make wheat-based foods healthier.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Efforts will be made to age and gender match subjects (balanced number of males and females in each group). Subjects are appropriate if they are in the age range between 18 and 60. Women who are in the reproductive age will be studied at the first half of their menstrual cycle, because estrogen is known to affect the energy expenditure. Postmenopausal women taking hormonal replacement therapy will be excluded. Subjects should have: Cr \<1mg/dl for women and \<1.2mg/dl for men and GFR \>60 ml/min/1.73m2. Exclusion Criteria: * Subjects with diabetes, cardiovascular, cerebrovascular, pulmonary, hepatic, renal, endocrinological (PTH), or any significant medical disease will be excluded. * Pregnant and lactating women. * Subjects on regular use of medication that affects body weight and/or having a weight loss of 3% or more in the preceding 3 months. * Subjects with: Cr \>1mg/dl for women and \>1.2mg/dl for men and GFR\<60 ml/min/1.73m2.
