“However, findings from a recent study suggest that no level of caffeine consumption is safe when trying to conceive or during pregnancy. The authors reviewed 48 observational studies and meta-analyses of maternal caffeine consumption published during the last 20 years.”

“In dampening the A2 receptor signal, caffeine might reduce the formation of new connections and potentially dampen levels of neuronal activity to a point where some connections may be eliminated.”

“Even with these constraints, the study provides causal evidence linking sustained caffeine exposure to metabolic benefits. In episode #103, I synthesize extensive research to illuminate how the timing, brewing methods, and additives to coffee influence its health benefits and risks.”

“Coffee is perhaps best known for its stimulant properties, primarily from its caffeine content. Recent research found that caffeine and its metabolites reduce the risk of Parkinson's disease, a progressive neurodegenerative disorder affecting more than 10 million people worldwide.”

“Caffeine that was given to people 3 hours before normal bedtime caused a 40-minute shift in the body's internal clock, about half of what 3 hours of bright light exposure at night did. Chronic caffeine exposure caused a lengthening of the circadian clock in human cells (in-vitro) via changing adenosine receptor signaling.”

“FTA: > Researchers report that decaffeinated coffee drinking may benefit liver health. Results show that higher coffee consumption, regardless of caffeine content, was linked to lower levels of abnormal liver enzymes. This suggests that chemical compounds in coffee other than caffeine may help protect the liver.”

“Because caffeine consumers might not perceive the disruption, they may be more likely to repeat the cycle, unknowingly trading long-term rest for short-term alertness. Learn about other factors that influence sleep quality in this clip featuring Dr. Matt Walker.”

“There have been several associative studies that have found that caffeine consumption is associated with a 36% lower dementia risk. But this study was an in-vitro study (meaning it was done in cultured cells) so it is too early to say whether drinking a cup of coffee will boost the activity of this enzyme in humans but hopefully, future studies will illuminate this.”

“Overall, decaffeinated coffee—whether solvent-based, water-based, or CO2-processed—is widely considered safe and nutritionally robust. Each method effectively removes caffeine while largely preserving coffee's beneficial antioxidants, minerals, and flavor compounds.”

“Surprisingly, caffeine didn't explain the difference. When the researchers adjusted for both caffeinated and decaffeinated coffee intake, the timing of coffee drinking still mattered.”
