High-intensity interval training (HIIT) improves brain function, including boosting neurogenesis, BDNF (brain-derived neurotrophic factor), and spatial memory in the hippocampus of rats.

Mice who consumed the food dyes FD&C Red 40 and Yellow 6 developed colitis, a form of inflammatory bowel disease, when levels of the immune cytokine IL-23 were dysregulated.
