Prof. David Ma, Human Health and Nutritional Sciences, was interviewed by the Toronto Star Feb. 1 about proposed regulations on food and drinkĀ  advertisements. The Canadian Heart and Stroke Federation is calling on the federal government to regulate food and beverage ads aimed at children and youth in an attempt to fight childhood obesity. Ma said regulation could be a good first step but more needs to be done to make children healthy. He studies the role of nutrition in human health, and is one of the leaders of the Guelph Family Health Study, a massive research project aiming to help families implement healthful behaviours early in life.
