Adverse effects of maltodextrin consumption include an increase in insulin production and subsequent rise in blood sugar levels, according to Integrative Wellness Centers. This is due to maltodextrin having a glycemic index of 130, compared to table sugar's glycemic index of 65.
Maltodextrin is commonly found in products marketed as low-fat, no- or low-sugar and diet foods, as it provides less calories than regular table sugar, as Integrative Wellness Centers notes. However, since it has a higher glycemic index, it causes a more rapid spike in blood sugar levels and increased insulin output. Insulin is a growth hormone, so this can lead to hormone abnormalities in men and women. Such abnormalities include irregular and/or heavy periods, increased facial hair growth and feelings of irritability.
