Abstract

Fish contains nutrients that are positive for our health. At the same time, it contains varying levels of undesirable substances that can have a negative effect on health. Undesirable substances can be found in different levels in most types of food. In a risk-benefit assessment, both the nutrients and the undesirable substances are assessed and it is evaluated whether it in total gives a more positive effect to eat certain foodstuff than not, and possibly how much one should eat to achieve optimal use of the positive health effects.
