NUTR 120 Lecture Notes - Lecture 11: High Fructose Corn Syrup, Corn Starch, Supersaturation
Document Summary
Less cariogenic than other sugars cariogenic = means cavity causing. Hfcs high fructose corn syrup (hfcs 55% fructose: liquid sweetener made from corn starch. Intake (consumption): 0% in 1970 33% all sugar intake today. It is a 1000% increase since the 70s: used to sweeten soft drink, sauces, condiments, and etc. It is found in everything: used a lot in us since they have a lot of corn; sucrose is relatively more expensive. Average u. s. consumes > 62 lbs hfcs/year ~130 kcal/day of all u. s. (> 2 years of age) Table that shows that the rise of sugar intake correlated w/ the rise of obesity rate. Consider: body uses fructose differently than other sugars (not all of them is converted into glucose) Does not stimulate insulin secretion or enhance leptin production (therefore, people remain hungry, no satiety cue) Stimulate liver fat synthesis (cid:894)(cid:862)de (cid:374)o(cid:448)o lipoge(cid:374)esis(cid:863) vdl ) therefore, an in blood tg. Soda pop has about 15 tsp sugar/cup.
