Canada's healthy-eating guide fights to stay relevant

Since World War Two, the Canadian government has been telling people what to put on their plate to stay healthy. But with obesity rates on the rise, is it time to start focusing on what to leave off?
Canada's food guide first appeared in 1942 under the title Official Food Rules and was originally created to help Canadians stay strong and healthy despite meagre wartime rations.
The guide recommended drinking fruit juice, loading up on bread and eating plenty of liver.
Over the years, the publication has used many designs to illustrate the different food groups. In the US, the "food pyramid" became an instantly recognisable illustration of nutritional categories but Canada switched from a "food wheel" to a "food rainbow".
The Canadian government used to be concerned about people getting enough food, now it's worried people are getting too much. In the new year, Health Canada will start drafting a new food guide aimed at getting people to eat less.
Despite the commitment to changes, food historian Ian Mosby says the guide may have simply outlived its usefulness.
"It was started as a way to prevent malnutrition. But it's hard to see what it's doing in an era where those are not the main health problems facing Canadians."
When the Canadian government released its rules for healthy eating in 1942, it was marketed as a guide to "health-protective foods". The rules laid out the bare minimum that a person should eat in order to stay nourished.
"Eat more if you can," the rules advised.
Daily servings of Vitamin-C rich citrus fruit or tomatoes were advised, along with weekly servings of liver for iron.
Food was expensive in the 1940s and 1950s, and overeating was a luxury few experienced. According to a 1955 survey of household spending, the average family spent about 30% of their earnings each week on groceries, the bulk of which was spent on meat and dairy products.
But by the 1970s, rising incomes and the growing commercialisation of food had completely transformed how people eat, says Mosby.
Sugary cereals, trans fats and TV-dinners became a staple of many people's diets.
As the price of packaged foods high in sugar and salt plummeted, overconsumption became a bigger problem. The government could no longer just tell people what they should eat, they had to tell people how much.
Consequently, the old black-and-white list of Official Food Rules got a Technicolor makeover and was transformed into Canada's Food Guide, a consumer-friendly guide for making better food choices.
Critically, a warning to eat sugar, fats and salts in moderation was added in 1982.
But Canada's overeating problem didn't go away. Since 1985, the obesity rate has tripled. Canadians are spending less and less on food overall, but more on eating out and sugary beverages.
It's possible, food historian Mosby says, to be both obese and malnourished.
In 2014, the average Canadian household spent just under C$6,000 (£3,622) a year on groceries, or 8% of their annual salary, including C$1,300 on beverages like juice and soda, which provide mostly empty calories.
To encourage people to eat better, the most recent edition of the guide made produce, not grains, the main food group.
But the guide hasn't gone far enough, says Canada's Health Minister Jane Philpott.
Philpott is leading the charge to change the guide once again in the new year. She wants to make it simpler to understand and come down hard on processed foods and trans fats.
Mosby says that if the guide hopes to remain relevant, it must be backed up with policy changes that make healthy eating more affordable and put limits on sugars and fats in foods.
"These issues are not going to be solved through education" alone, he says.
