ACADEMIC GUIDE

Contents overview

We ingest toxic substances every day throughout our diet. Some of these substances are deliberately added to food during processing (e.g. additives), others occur naturally (toxins from microorganisms, plants and animals), and yet others are incorporated into food as a result of environmental pollution (pesticides, heavy metals and industrial waste substances). How do toxic chemicals end up in our food? Where do they come from? Is there a risk associated with food toxicants? Are all types of food equally healthy? Can we reduce the ingestion of food toxicants?

The science of food toxicology aims to quantify the presence of toxic substances in food, evaluate their adverse effects and establish an acceptable daily intake for consumers. This course will cover basic concepts on food toxicology by combining theoretical classes with student-centered learning activities, including laboratory practical classes, student presentations, computer simulations, games, class discussions, videos, readings, case studies, and a toxic potluck for the final day of class. Most of the learning activities will be held during the presencial lectures but some activites will require homework. The student is expected to work individually and collaboratively with the rest of the class.
