Reasons for and against the use of food additives
For:
- Food additives keep food safe by lengthening the shelf life.
- Many foods are kept safe to eat for longer through the use of preservatives (e.g., meat). These additives protect consumers from food-borne illnesses through limiting the growth of harmful bacteria. This allows foods to be kept on a shelf for longer and helps reduce waste.
- Food additives can make foods more appealing by enhancing the flavour, colour or texture.
- Manufacturers may add flavour enhancers, sweeteners, colours or thickeners to a food to make it more enjoyable for consumers by improving the final look and feel of the product.
- Food additives can enrich foods and improve or maintain nutritional value
- Some foods have additives added which improve the nutritional composition of the product. For example, by adding ascorbic acid (vitamin C) to a food.
Against:
- Food additives have been linked with adverse health effects such as cancer and allergic reactions.
- There are some additives that have controversial research linking them with carcinogenic (cancer-causing) properties. For example, sodium nitrite, used to preserve meat has been linked to increased levels of bowel cancer.
- Food additives have been linked with affecting some children's behaviour and health.
- Some food colourings and preservatives have been linked to hyperactivity in children when consumed in extremely high quantities.
- Some food additives have been related to headaches and migraines in children, as they are more sensitive to certain substances than adults.
- Food additives can make food products appear 'better' than they are.
- Additives such as bulking agents or flavour enhancers may be added to lower quality food products to make them appear more attractive to consumers.
