Chemical Markers and Bioactivity of Algerian Royal Jelly: Influence of Bee Subspecies, Geography, and Lyophilization

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Algerian royal jelly from native honey bees shows chemical diversity influenced by geography and subspecies. Lyophilization preserves key compounds, including 10‐HDA and phenolics. Biological assays reveal modest antioxidant activity and selective cytotoxicity against Reh leukemia cells, while anti‐inflammatory effects are limited.

Planetary Health Diet Adherence Improves Weight and Body Composition During Energy Restriction

Obesity, Volume 34, Issue 6, Page 1265-1276, June 2026.
ABSTRACT Objective Obesity management relies on energy restriction, yet the contribution of dietary quality to weight‐loss and body composition outcomes during hypocaloric interventions remains poorly characterized. This study evaluated whether adherence to the Planetary Health Diet (PHD), as a measure of diet quality, and its key components is ...
