Coffee and Fruit Juice Linked to Lower Dementia, Diabetes and Improved Mood

Regular consumption of coffee – typically two to four cups a day – is associated with longer telomeres, an estimated five‑year reduction in biological age, an 18% lower risk of dementia and up to a 30% lower risk of type‑2 diabetes, according to studies reported by King’s College London, the Journal of the American Medical Association and Harvard researchers. The health benefits are strongest for filtered coffee, while unfiltered coffee may raise cholesterol.

A four‑week UK trial involving 42 adults who normally ate few fruits and vegetables found that adding a daily glass of 100 % fruit juice or a smoothie helped participants meet the “five‑a‑day” guideline and led to a measurable improvement in mental wellbeing. Those who drank the juice reported depression scores 2.5 points lower on a 27‑point scale compared with a control group that increased only whole produce intake.
