Context:

Coffee and tea are both rich in health-promoting compounds that may offer protection against various diseases, including cancers and diabetes. Research indicates that moderate consumption of these beverages can enhance longevity and reduce all-cause mortality risks. Coffee, with its higher caffeine content, may improve athletic performance and protect against liver conditions, while tea, particularly green tea, is associated with mental health benefits and heart disease protection. Despite their benefits, excessive caffeine intake can lead to adverse effects, prompting recommendations to limit daily consumption. Future studies may further clarify their health impacts and optimize guidelines for safe intake.

Dive Deeper:

• Both coffee and tea contain antioxidants and health-protective compounds that may lower the risk of developing chronic diseases, including type 2 diabetes and certain cancers.

• A 2023 study found that individuals consuming two cups of tea and two cups of coffee daily had a 21% lower risk of cancer-related death, while those drinking three cups of tea and four cups of coffee had a 24% lower risk of all-cause mortality.

• Coffee contains approximately 91.8 mg of caffeine per cup, significantly more than black tea at 47 mg and green tea at 29.4 mg, influencing its effects on athletic performance and liver health.

• Regular coffee consumption is linked to a 23% lower risk of non-alcoholic fatty liver disease and a 32% reduction in liver fibrosis compared to non-drinkers.

• Green tea's L-theanine is associated with a 34% reduction in depressive symptoms, while regular tea intake helps lower LDL cholesterol, contributing to cardiovascular health.

• Experts recommend limiting caffeine intake to less than 400 mg per day for adults and 200 mg for pregnant individuals to avoid side effects like anxiety and high blood pressure.

• Future research may provide deeper insights into the long-term health effects of coffee and tea, informing dietary guidelines for their consumption.
