Most cultures have food-related taboos, often connected to religion and spirituality. They are often deeply held and may very drastically from country to country, region to region or even person to person. Horse meat for one is a priced delicacy in parts of France and (traditionally) in the Rhineland, whereas many people in an area as close as Southern Germany are disgusted at the thought. With very few exceptions these taboos relate to meat and animal products, so tread with caution.
Table etiquette differs a lot between countries. In parts of Africa and Asia, people designate one hand (usually the right) for eating, while the other hand is used at the toilet. Behaviour such as burping or slurping might be common at a fine diner in one country, but very impolite in another.
Many Europeans regard eating with a fork and knife to be a cornerstone of good table manners. However, cutlery were not commonly used in any European country until the 19th century, and have only been recently adopted on other continents. The American custom to cut all food on the plate, and eat with the fork in the right hand, is commonly accepted today, and can even be seen at occasions such as the Nobel Prize dinner.
