They advise people to eat more fruits and vegetables and less meat such as beef and pork because meat contains more fat than poultry and fish. Fat can build up in the arteries, block the flow of blood, and cause a heart attack or stroke. Getting rid of bad habits like smoking and drinking alcohol is also an important way to keep healthy.
