In conclusion , it was shown that very high fructose intake ( > 100 g/d ) increases serum LDL-C and TC concentrations .
Fructose is widely used as a sweetener in the production of many foods , yet the relation between fructose intake and cholesterol remains uncertain .
In this study , we performed a systematic review and meta- analysis of human , controlled , feeding trials involving isocaloric fructose exchange for other carbohydrates to quantify the effects of fructose on serum total cholesterol ( TC ) , LDL cholesterol ( LDL-C ) , and  HDL cholesterol ( HDL-C ) in adult humans .
Glycemic index of foods: a physiological basis for carbohydrate exchange.
The determine the effect of different foods on the blood glucose , 62 commonly eaten foods and sugars were fed individually to groups of 5 to 10 healthy fasting volunteers .  Blood glucose levels were measured over 2 h , and expressed as a percentage of the area under the glucose response curve when the same amount of carbohydrate was taken as glucose . The largest rises were seen with vegetables ( 70 + /- 5 % ) , followed by breakfast cereals ( 65 + /- 5 % ) , cereals and biscuits ( 60 + /- 3 % ) , fruit ( 50 + /- 5 % ) , dairy products ( 35 + /- 1 % ) , and dried legumes ( 31 + /- 3 % ) . A significant negative relationship was seen between fat ( p less than 0.01 ) and protein ( p less than 0.001 ) and postpr and ial glucose rise but not with fiber or sugar content
