Preventing cardiovascular disease is a high priority for most people. According to statistics from the National Heart, Lung and Blood Institute, 831,272 Americans died in 2009 from cardiovascular diseases. The devastating effects of conditions such as heart attacks are tragic, and because treatment can be too late in such circumstances, prevention is the most important factor in addressing the issue. Diet is crucial in developing and protecting a healthy cardiovascular system.
Function
The American Heart Association (AHA) states that the best way to fight cardiovascular disease is through a healthy diet and lifestyle. A healthy diet supports cardiovascular health by providing the cardiovascular system with the nutrients it needs to do its job, and by eliminating harmful foods that will weaken it. Unhealthy trans and saturated fats block arteries, and foods high in sodium increase blood pressure. Obesity puts an extra strain on the heart, and is listed by the AHA as a major risk factor for heart attacks.
Public Awareness
The connection between an unhealthy diet and cardiovascular disease has been the focus of debates, lobbying and legislation at both the local and national level. The unhealthy food practices of the fast food industry and their effect on health have been a source of controversy; the proposed moratorium on building new fast food restaurants in Los Angeles that was highlighted in a Sept. 10, 2007 issue of the "Los Angeles Times" is an example of this controversy. The public is becoming increasingly aware of the connection between diet or diet-related issues such as obesity, and cardiovascular disease. Attention is now given to promoting a healthy lifestyle and weight at a young age, such as the national campaign begun in the United States in early 2010 to help fight childhood obesity.
Benefits
While some organ systems appear localized, others, like the cardiovascular system, affect the entire human body. A healthy cardiovascular system that is able to efficiently transport nutrients and oxygen allows all other body systems to function and perform their tasks. Increased energy, concentration and immune response are among the advantages of a healthy cardiovascular system.
Features
Several basic nutrition principles are involved in a heart-healthy diet. According to the AHA, fiber can reduce blood cholesterol levels. Include plenty of whole grains, fruits and vegetables in your diet. These foods also help control weight and blood pressure, and provide your body with a variety of needed vitamins and minerals. The AHA also encourages eating fish at least twice a week to gain benefits from the omega-3 fatty acids fish contains. A heart-healthy diet is low in sodium, which also helps reduce blood pressure.
Lifestyle
A healthy diet alone cannot prevent cardiovascular disease, and other lifestyle choices must accompany heart-friendly eating. The AHA strongly recommends a non-smoking lifestyle, and states that there is a powerful connection between nicotine use and heart attacks. Additionally, exercise is very important to keeping the heart in shape and strong enough to meet the challenges presented to it.
