Fat and Sugar, Part 2

Listen to Full Episode 54:00

First, fat was the dietary bad guy. We were warned back in the 1980s to cut back on eggs, meat and full-fat dairy to avoid heart disease. So we started eating more bread, rice and pasta and fat-free snacks. But we got sicker and fatter. Now sugar is the bad guy. Contributor Jill Eisen explores the complex, and sometimes contradictory, science of nutrition -- and tries to find clarity amidst the thicket of studies and ambiguous research. **This episode originally aired June 22, 2016. 







 


France, Hungary, Norway, Britain and Mexico now impose taxes on soft drinks, and other governments are considering similar legislation.  Yet, while there's growing consensus that sugar is harming us, there's no consensus about why -- nor even if it really is dietary enemy number one. 

In the 1960's, long before the low-fat movement swept North America, our mothers warned us that if we didn't want to get fat, we'd better cut down on bread, pasta, potatoes -- and sweets. But then in the 1980's, everything changed. Suddenly, it was fat that made you fat. Governments in both Canada and the U.S. began advising everyone over the age of two to cut the fat and load up on carbohydrates. 

So North Americans started eating a lot more low-fat carbohydrates.  And to make all that low-fat food more palatable, the food industry started adding sugar to just about everything -- bread, tomato sauce, salad dressing, yogurt.  And to top it off, we washed it all down with low-fat drinks which were loaded with sugar. It was then that the twin epidemics of obesity and diabetes took off.
 

Fat and Sugar - Canada's Food Guides 1992 & 2008


In 1992, Canada's Food Guide recommended a whopping 5-12 servings a day of grain products, up from 3-5 servings in 1977. By 2007, the Guide had reduced the recommendation for grain product to 6-8 servings a day for adults.



Some Facts About Sugar

  • Most caloric sweeteners are made up of glucose and fructose. Sucrose -- table sugar -- is 50% glucose and 50% fructose. High fructose corn syrup has about 45% glucose and 55% fructose. From a metabolic point of view, table sugar and high fructose corn syrup are almost identical.

  • Canadians consume about half the amount of soft drinks than Americans. Source: Canadian Sugar Institute
     
  • "Added sugars" include all sugars, corn syrups, honey, and maple syrup added to foods and beverages. It does not include sugars that naturally occur in fruits, vegetables, and dairy products. It is estimated that Canadians consume approximately 11% of their energy (calories) as added sugars, equivalent to about 53g of added sugars per person per day. Source: Canadian Sugar Institute
     
  • The World Health Organization recommends that no more than 10% of total calories should come from added sugar.
