US cardiologist warns: Coffee and sugar may accelerate ageing and harm heart health; limit intake recommended

US cardiologist Dr. Sanjay Bhojraj warns that excessive coffee and sugar intake can accelerate biological ageing by causing persistent stress and inflammation. These habits strain the cardiovascular system, elevate cortisol, and disrupt sleep, increasing heart disease risk. Cravings indicate the body needs better fuel. While moderate coffee has benefits, sugary additives negate them.
