NUTR 120 Lecture Notes - Lecture 11: High Fructose Corn Syrup, Soft Drink, Dental Caries
Document Summary
Fibre slows down the process of digestion; tempers the glycemic response/initial spike in blood glucose levels. Food sources: fruit sugar, less cariogenic than sucrose. Less cavity-causing: high fructose corn syrup (hfcs) Increased availability and use as a commercial sweetener. North american intake has grown from 0% of sugar intake in the 1970s to 1/3 of all sugar intake now (>1000% change) Average american consumer will consume ~62lbs hfcs/year = 130kcal per day. Humans have never consumed anywhere close to current hfcs consumption: bodies cannot handle this amount very well. Just 1 daily 16-oz can (2 cups/500 ml) soda pop (200 kcal) can equate to a 20lb weight gain per year. Hints: 40oz (5 cups, soda pop has 100 kcal/cup, soda pop has about 15 tsp sugar/cup. Number of teaspoons of sugar: 12, 24, 58, 77. Yields more kcal/acre than any other food crop. ** studies since the 1980s have shown increased linkages between these issues and sugar intake.
