A healthy diet can help reduce your risk of developing coronary heart disease and stop you from 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.
The best way to understand it is to think of foods in food groups. Everyone should aim for a well-balanced diet - plenty of fruit and vegetables, plenty of starchy foods such as bread, rice, potatoes and pasta. Choose wholegrain varieties wherever possible. Some milk and dairy products, some meat, fish, eggs, beans and other non-dairy sources of protein.
Only a small amount of foods and drinks that are high in fats and/or sugar. Choose options that are lower in fat, salt and sugar whenever you can.
Salt
Eating too much salt can increase the risk of developing high blood pressure. Having high blood pressure increases the risk of developing coronary heart disease.
