Coffee Consumption Offers Brain Stimulation and Metabolic Benefits but Excess Intake Risks High Blood Pressure and Osteoporosis

Key summary

According to sources including MedPark Hospital, AllWell Healthcare, and Suan Sunandha Rajabhat University, coffee contains high levels of caffeine and can improve alertness, increase calorie burning by up to 79 calories per day at a dose of 300mg, and reduce risks for liver disease, type 2 diabetes, and headaches. However, excessive consumption may lead to hypertension lasting up to 12 hours after a single cup, stomach ulcers due to increased acid secretion, reduced absorption of minerals like calcium, iron, and zinc, osteoporosis from calcium loss in urine, and accelerated skin aging. Experts recommend drinking black coffee without sugar or creamer in moderation (1-2 cups daily) to maximize benefits while minimizing risks.
