Caffeine

Caffeine may help prevent stress-induced depression-like symptoms in mice by protecting gut health and reducing inflammation. While more research is needed, the findings raise the possibility that everyday dietary habits could play a meaningful role in mental health

Drinking coffee might wake you up even without the caffeine. Researchers found that habitual coffee drinkers responded similarly to both regular and decaf coffee, pointing to the influence of expectation and ritual on alertness and brain activity.

Caffeinated coffee improved strength and sprint performance in trained men, regardless of chronotype or time of day.

New evidence suggests 1-MX, derived from caffeine, may enhance learning and protect the brain from age-related decline.

Caffeine may help rugby sevens players sustain effort and agility in tournament play, according to new research.

A new study finds drinking caffeinated coffee slightly changes how older adults maintain balance but does not significantly affect stability or physical function. A strong cup of coffee is unlikely to increase fall risk.

Slow caffeine metabolizers excel in emotion recognition with high caffeine intake, while fast metabolizers perform better in executive function tasks with moderate caffeine consumption.

Consuming unsweetened caffeinated coffee is linked to a lower risk of Alzheimer’s, Parkinson’s, and related mortality, while sweetened or artificially sweetened coffee showed no such benefits.

A Spanish study found that 6 mg/kg of caffeine improved reaction time but caused nervousness and increased energy, while 3 mg/kg had no effect.

Researchers found that caffeine blocks alcohol’s ability to increase dopamine in brain reward areas, potentially reducing alcohol's rewarding effects. This suggests caffeine could play a role in preventing or treating alcohol addiction.

Research found no causal link between moderate coffee intake during pregnancy and children’s neurodevelopmental issues, supporting guidelines that low to moderate caffeine consumption (under 200mg daily) is safe for expectant mothers and their babies.

Adding coffee polyphenols to the diets of male mice exposed to early-life stress improved cognitive function and increased microglia survival, suggesting a potential nutritional intervention for mitigating stress-induced cognitive deficits.
