Coffee Reduces Mortality Risk: Prospective Cohort Evidence

Dr. Kumar’s Take

This landmark cohort analysis found that people who drink coffee tend to live longer, with lower deaths from several major causes. It is observational, so we cannot claim causation, but the pattern is consistent and aligns with other datasets and mechanisms.

Key Takeaways

• Habitual coffee intake is associated with lower all-cause mortality.
• Inverse associations extend to cardiovascular, neurologic, and metabolic causes in adjusted models.
• Signals appear in both caffeinated and decaf drinkers, implicating non-caffeine compounds.
• Lifestyle confounding is possible, but findings persist after extensive adjustment.

Actionable Tip

If you enjoy coffee and tolerate it well, 2–4 cups daily is compatible with favorable long-term outcomes. Keep added sugars minimal.

Coffee Health Benefits: Umbrella Review of 67 Meta-Analyses

Dr. Kumar’s Take

This review is one of the most comprehensive looks at coffee and health outcomes ever assembled. The findings are surprisingly consistent: habitual coffee intake is linked with lower mortality and reduced risk of several chronic diseases, especially those involving the liver and metabolism. While we cannot prove causation, the magnitude and consistency of these associations suggest that coffee, when not overloaded with sugar, is part of a healthy dietary pattern.

Vitamin C, Coffee, Milk, and Alcohol: How Diet Impacts Gout Risk

Dr. Kumar’s Take

This review pulls together the strongest evidence on how everyday foods and drinks shape uric acid levels and gout risk. The key theme is balance: certain choices like low-fat dairy, vitamin C, and coffee lower risk, while alcohol, especially beer and spirits, consistently drives it up. Tea remains more uncertain, with mixed findings.

Key Takeaways

✔ Vitamin C (≥ 500 mg/day) lowers uric acid and reduces gout risk, though effect size is modest.
✔ Coffee (≥ 4 cups/day) is linked to lower uric acid and lower gout risk.
✔ Milk and yogurt consumption is consistently protective against gout.
✔ Beer and spirits significantly increase uric acid and gout risk; wine appears neutral in moderation.
✔ Tea shows mixed results, with no clear protective effect.

Coffee and Uric Acid: How Your Morning Cup Impacts Gout Risk

Dr. Kumar’s Take

This study shows that coffee drinkers may have lower uric acid levels and reduced risk of hyperuricemia, a condition that often leads to gout. Interestingly, it was not caffeine but other compounds in coffee, like antioxidants such as chlorogenic acid, that seemed to drive the benefit. Tea and overall caffeine intake had no effect. For patients at risk of gout, adding coffee to the diet could be a safe, simple lifestyle change.
