MINERAL BIOUTILIZATION AS AFFECTED BY SUGARS
Abstract
The utilization of selected minerals when sugars were supplemented to basal diets was investigated in two different human studies. Fructose-fed subjects had higher fecal excretions of iron and magnesium than did subjects fed sucrose. Apparent magnesium, calcium, and phosphorus balances tended to be less positive during the fructose feeding period as compared to balances during the sucrose feeding period. Conversely, high fructose corn syrup feeding (HFCS) did not affect the mineral balances when compared to sucrose feeding. Subjects fed fructose experienced diarrhea which possibly decreased absorption of minerals and thus increased fecal mineral losses. No such adverse effects were noticed when HFCS was fed. The effects of different sugars on mineral bioutilization of weanling mice were investigated. Apparent iron absorption of mice fed fructose sweetened water was poorer than was that of mice fed sucrose, glucose, and HFCS sweetened water or plain distilled water. Although values were not significantly different, apparent zinc utilization of fructose-fed animals tended to be poorer than was the zinc utilization of the other groups. Mice consumed more glucose in water than fructose, sucrose, or HFCS. Addition of glucose resulted in a decrease of diet consumption. Conversely, addition of HFCS and fructose resulted in significantly lower intakes of sweetened water but higher intakes of mouse chow. Fructose-fed animals had lower calcium and iron liver stores than did mice fed glucose. Soft drink consumption and mineral status of 112 adolescent children were studied. Calcium, phosphorus, and iron intakes were positively correlated with total calories consumed, particularly when calories were not derived from soft drinks. Increasing calories from soft drinks decreased mineral intakes, particularly that of calcium. Males consumed more regular soft drinks than females. Conversely, females tend to consume more diet soft drinks than males.
