Poor nutrition is a significant risk factor for coronary artery disease because it often leads to an imbalance of nutrients that can adversely affect heart health. Diets high in saturated fats, trans fats, cholesterol, and sodium can contribute to weight gain, hypertension, and dyslipidemia, all of which increase the risk for developing coronary artery disease. Additionally, poor nutrition can result in a deficiency of essential nutrients, such as vitamins and minerals, which are crucial for maintaining cardiovascular health.

In contrast, regular exercise promotes cardiovascular fitness and helps maintain a healthy weight, which is protective against coronary artery disease. A high fiber diet is beneficial as it can help lower cholesterol levels and improve overall heart health, while low alcohol consumption, when done in moderation, can also have a protective effect on the cardiovascular system. Therefore, poor nutrition stands out as a significant risk factor that can lead to the development of coronary artery disease.
