An article on the new WHO guidelines wonders if their 26 g of sugar per day guideline is too extreme, since we eat so many foods like these:
1 can tomato soup: 30 g sugar
1 blueberry muffin: 22 g sugar
I serving Orange chicken: 22 g sugar
1 cup pasta sauce: 20 g sugar
1 cup coleslaw: 23 g sugar
Hidden candy everywhere!
