A US doctor, Dr. Kunal Sood, has outlined five daily habits to improve heart health and reduce cardiovascular disease risk. These include eating home-cooked meals, which are typically lower in sodium, sugar, and unhealthy fats. He also advises against sugary beverages due to their link to increased heart disease and stroke risk. Increasing dietary fiber intake is recommended for lowering LDL cholesterol and blood pressure. Additionally, short walks after meals can help manage blood sugar spikes, benefiting cardiovascular health.
