Anything that raises blood sugar—in particular, the consumption of refined and easily digestible carbohydrates—wil increase the generation of oxidants and free radicals; it wil increase the rate of oxidative stress and glycation, and the formation and accumulation of advanced glycation end-products.
Dextrose or D-glucose is the form of glucose found naturally in foods such as fruit and honey. It is also derived from plants, like corn, for use as a sweetener in foods. According to the Sugar Association, dextrose is crystalline glucose, and a majority of dextrose in foods is derived from cornstarch. If dextrose has been added to a food, it may be listed on the ingredients list as "rice sugar," "wheat sugar" or "corn sugar," depending on the plant source. Manufacturers may also list added dextrose or glucose as "glucose," "dextrose" or other terms containing the word "glucose" or "dextrose." Dextrose is added to many foods including desserts like cake mixes, cookies, custards and sherbets as well as in snack foods like crackers and pretzels

In addition, physical exertion may evoke a desire for food so that the subsequent intake of calories may exceed what was lost during the exercise.”
