Diabetic Snack Bars

The past few years has seen the growth of a new category of foods - diabetic snack bars. Some are formulated to prevent hypoglycemia while others are designed to reduce hyperglycemia.

They are intended to be used as a snack or partial meal replacement, to be eaten in the context of the individual's meal plan. The bars designed to prevent hypoglycemia include uncooked cornstarch (UCS), a slowly absorbed complex carbohydrate that acts as a continuous source of glucose. Those that aim to reduce hyperglycemia use ingredients such as resistant starches and fiber, which help to blunt the postprandial (after a meal) glycemic response.

In a recent scientific review of these products, diabetes specialists made these recommendations:

  • People on intensive insulin therapy treatment plans who are in very good control may benefit most from using the snack bars containing UCS because they are more susceptible to episodes of hypoglycemia.
  • These products should NOT be used to treat hypoglycemia; they are not formulated to act quickly.
  • Snack bars with UCS are good as part of a bedtime snack to prevent hypoglycemia at night.
  • Snack bars without UCS are meant to help prevent hyperglycemia during the day.
  • Snack bars meant for daytime use may not be suitable as nighttime snacks.
  • The various types of snack bars are not interchangeable, even though their carbohydrate content may be similar.
  • Snack bars containing UCS may help to avoid low blood glucose after drinking alcohol.
  • People who suffer from hypoglycemic unawareness may benefit from snack bars with UCS to help prevent hypoglycemia.
  • Both types are preferable to regular snack bars, including health bars, energy bars, or candy bars, which may cause exaggerated glycemic responses.
