The World Cancer Research Fund and the American Institute for Cancer Research recently looked at how food affects cancer rates. The study showed that added salt and chemical preservatives and colors increased cancer risks.
Many processed foods can be directly linked to an increased risk of stomach cancer, and too much salt, leads to other complications such as hypertension. Processed foods can often lead to obesity too, which can increase the risk of some cancers.
Other research has shown that about 30% of all cancer deaths can be attributed to poor diet and exercise routines.
Eating as much fresh fruit, vegetables and lean white meat and wild fish can help in reducing these risks.
