Are food additives harmful during cancer treatment?

There is currently no evidence linking an intake of food additives (within the acceptable daily intake) approved by the European Food Safety Authority with an increased risk of developing cancer or interactions during treatment.


The European Food Safety Authority (EFSA) reviews the safety of food additives regularly with a very thorough evaluation, the last of which was completed in 2020 with later revaluations in some specific cases such aspartame (see sweeteners myth). The letter E indicates that it has been approved and is safe for human consumption. Therefore, foods containing food additives can be part of a healthy and balanced diet. However, a healthy diet is one based on fresh, local and seasonal foods, with little or no processing, and above all without ultra-processed foods, so the intake of additives should be very low.
