A healthy diet can help reduce your risk of developing coronary heart disease and stop you gaining weight, reducing your risk of diabetes and high blood pressure.
It can also help lower your cholesterol levels and reduce your risk of some cancers.
Even if you already have a heart condition, a healthy diet can benefit your heart.
For someone with heart disease, diet is a big deal. Along with other healthy habits, it can slow or even partially reverse the narrowing of vessels that supply blood to the heart muscles.
This is very important as this reduces the risk of a heart attack.
