Key Takeaways
\nA balance of water, coffee, and tea is linked to a longer life. Research suggests that drinking around 7\u20138 total cups per day\u2014and swapping some water for coffee or tea once you\u2019re above 4 cups\u2014may reduce overall mortality risk.It\u2019s the combination that matters. Hydration from water plus polyphenols in coffee and tea work together to support metabolic, vascular, and inflammatory health more effectively than any one beverage alone.Variety > volume. Rotating these drinks throughout the day delivers complementary nutrients and helps avoid excess sugar or caffeine\u2014making your daily beverage routine a meaningful part of long-term health.<\/p>\n
For most of us, no day would be complete without a rotation of our favorite beverages: water to start, then that first cup of coffee<\/a>, and maybe a juice or smoothie<\/a> to round out the day. But according to new research from the British Journal of Nutrition<\/a> and data from the UK Biobank, there\u2019s a specific selection of beverages that can make a difference not just in your day-to-day life, but also how long you live. Plain water, coffee, and tea can actually curb the likelihood of all-cause and cause-specific mortality\u2014here\u2019s why.\n<\/p>\n The Link Between Water, Coffee, Tea, and Longevity <\/p>\n \u201cUsing compositional methods, the authors found the lowest mortality at roughly 7\u20138 total drinks per day and, once people were above about 4 drinks per day, substituting some plain water with coffee and tea was linked to lower all-cause and cause-specific mortality,\u201d explains longevity dietitian Ella Davar, RD<\/a>. \u201cThe most favorable pattern was a balanced mix of coffee and tea within that total.\u201d Essentially, in addition to keeping you sufficiently hydrated<\/a>, the effects of drinking coffee and tea throughout the day can actually do you some good.\n<\/p>\n The study notes that previous research on the topic typically focused on the health benefits of coffee and tea<\/a> individually, rather than their combined benefits. Balanced consumption of coffee and tea was also associated with a decreased risk of chronic, cardiovascular, respiratory, and digestive disease. \u201cHydration is the base layer, and layering in polyphenol-rich coffee and tea appears to compound the benefit beyond water alone,\u201d Davar says. \u201cMechanistically, hydration supports perfusion and metabolic homeostasis, while coffee and tea polyphenols like chlorogenic acids [and] catechins offer antioxidant and anti-inflammatory effects<\/a> and may improve vascular and metabolic markers.\u201d\n<\/p>\n Another facet that sets this research apart from previous studies is its emphasis on variety\u2014it matters less how much you\u2019re consuming, but rather what you\u2019re drinking. \u201cVariety matters slightly more than volume,\u201d Davar says. \u201cDifferent beverages deliver complementary bioactives, like in coffee (chlorogenic acids), tea (catechins\/flavonols), [and] water (hydration) without additives, and rotating them avoids excess sugar or ultra-hot intake while distributing caffeine over the day for better cardiorespiratory and glycemic stability.\u201d So the next time you\u2019re focused on drinking a gallon of water per day, take a beat and add some coffee and tea to the mix.\n<\/p>\n
