Food additives and cancer
Food additives are chemicals that help preserve, colour and flavour our food. It is very unlikely that food additives cause cancer.
Food additives are subjected to safety testing before they are even considered for approval by the Health Products and Food Branch, Bureau of Chemical Safety of Health Canada. Once approved and in use, all food additives are continuously monitored and reviewed for adverse reactions and hazards. If at any time the safety of a food additive is shown to be harmful, it is removed from the market.
Any food dyes or cosmetics that were once linked to cancer are no longer used in Canada.
Aspartame (also known as Nutrasweet) does not cause cancer. Cyclamates and saccharin in high doses have caused cancer in laboratory rats, but there is no proven link between these substances and cancer in humans. It is advisable to use these artificial sweeteners in moderation.
Great progress has been made
Some cancers, such as thyroid and testicular, have survival rates of over 90%. Other cancers, such as pancreatic, brain and esophageal, continue to have very low survival rates.
