Research has shown that consumers often miscalculate the number of calories and the nutritional content of products that have two or more servings per container but are usually consumed in a single eating occasion.

Many people overestimate the size of one serving of food as defined in Canada's Food Guide, so they may be overeating even if they believe they are being careful.

New research suggests color -- the color of the plate and even the color of the tablecloth -- affects how much people serve themselves.
