Cardiovascular disease (CDV) is a cluster of diseases that occur as a result of the formation of a substance called plague in the walls of the arteries. CDVs take many forms such as stroke, coronary artery disease, valvular heart disease and rheumatic heart disease. CDV causes over 12 million deaths in the world annually, and is also responsible for almost half of all deaths in America. In my opinion, poor diets and physical inactivity are the most risk factors for cardiovascular disease.
The influence of diet and habitual physical activity on the function and structure of the cardiovascular system can not be ignored (Sinatra et. al., 13). Regular aerobic exercise combined with healthy diet has many effects in the manner in which the cardiovascular system. It has been proven that a combination of the two improve the circulation of oxygen as well as the hearts efficiency to pump oxygen to various tissues of the body. Moreover, regular physical activities improves the efficiency with which body cells, especially skeletal muscles utilize oxygen. This limits the demand on the heart, therefore slowing the heart rate, and as a result decreasing blood pressure.
Poor diet and lack of regular physical activity often result to weight issues and obesity, which are the commonest risk factors for CDV. It is imperative to understand that the role of nutrition and diet is influence by a myriad of cultural, social, psychological, and economic factors, including the availability and cost of food (Sinatra et. al. 67). In this regard, strategies to reduce the stated risk factors involve being involved in physical activities, changes in behavior, and diet, or a blend of all three. Dietary changes include and increase and an adequate consumption of vegetables and fruits as well as a reduction in salt intake.
Note that the lifetime risk for individuals to develop CDV is about 1 in every 5 or 21.2 percent for those who do not adhere to any lifestyle choices, i.e. those who smoke, are overweight, or eat poor diets. On the other hand, those individuals who practice healthy lifestyles, their lifetime risk is 1 in every 10 individuals or 10.1 percent.
