How to prevent cardiovascular disease?

how to have healthy lifestyle

eat healthy -- meaning eat fresh vegetables, fruits (that are not high is sugar) and lean protein (take off the skin and fat -- these are "saturated fats" that clog up your arteries).
exercise is also suggested -- find one that is suitable for you. it should be good enough that you feel your heart racing when you do it, but not too strenuous that it causes too much discomfort. you should still be able to talk while exercising, don't push yourself too hard.
avoid foods that are "processed" or "preserved" these contain too much sodium (used for preserving them) and too much sodium (im not saying all) is bad for you -- they cause water retention which causes hypertension and makes it harder for your heart to pump all those fluids out.
if you are smoking, quit smoking -- there is no "safe number" of cigarettes that you can smoke a day, if you are serious about quitting - quit it cold turkey. smoking WILL cause lung problems and ALSO vascular problems -- they constrict your blood vessels and makes it harder for the heart to pump blood through narrowed holes.
