To ensure good cardiac and vascular health it is important to try to fit in 30 minutes of cardio exercise a day. Whether it is in the form of walking, running, biking, swimming and so forth, 30 minutes of cardio exercise a day will keep your heart strong and your blood flowing. As for diet avoid trans fats and saturated fat. These unhealthy fats are detrimental to cardiac and vascular health because they cause plaque buildup that can lead to heart attack and stroke. Limiting your intake or avoiding consumption of these fats altogether is the wisest choice. Avoid foods that contain these unhealthy fats such as fried or battered foods. Add healthy fats to your diet, such as olive oil, nuts and seeds, fatty fishes, and grass-fed meat to protect your heart from plaque buildup. Also, maintaining an adequate level of Vitamin D is essential for a healthy vascular system.
