Consequentially, the heart has to pump much harder to circulate the blood. An unhealthy diet also leads to high blood pressure which further increases the build up of plaque and other fatty matter in the arteries. All of this plaque causes decreased blood flow to the heart which makes it weaker. Although the decreased flow of blood can cause heart problems later on, the real danger is the risk that a piece of the plaque could break off, leaving a gap.
