Final answer:
All food sold in Canada must indeed be safe for human consumption, with measures in place such as Calgary's trans fat ban in restaurants and fast food outlets since 2008, reflecting a broader push toward food safety and environmental sustainability.
Step-by-step explanation:
True, all food sold in Canada must be fit for human consumption. This means that the food must meet certain safety standards and nutritional guidelines to ensure that it is safe to eat. Initiatives have been taken over the years to improve food safety and public health. For example, many nations, including Canada, have set limits on the amount of trans fat that can be in food products, due to its negative health effects. Calgary was the first city in Canada to implement a trans fat ban in restaurants and fast food establishments, starting on January 1, 2008. Moreover, there is a growing consciousness about the impact of food on health and the environment, emphasizing the need for sustainable production and consumption practices. Consumers are encouraged to choose local, in-season fruits and vegetables, reduce waste, and be aware of the nutritional content and ecological footprint of their food choices.
