Cardiologists are reportedly advising individuals, particularly those over a certain age, to make certain changes to their diet and daily habits for better heart health. The specific age and recommendations vary, with some outlets suggesting that people over 50 or 60 should eat more of a particular high-fiber or high-protein food, while others advise against certain habits or foods. The exact nature of the recommended changes is unclear, with conflicting reports on what cardiologists are advising people to eat or avoid.
