Polyalditol

Polyalditol is a functional sugar alcohol often derived from renewable plant sources like corn or birch wood. Unlike regular sugar, it provides fewer calories and has a minimal impact on blood sugar levels, making it a popular choice for low-carb diets and dental-friendly products. It serves as a sweetener and a bulking agent, giving texture to 'sugar-free' foods. While it sounds chemical, it occurs naturally in small amounts in fruits like pears and peaches. It's a tool for enjoying sweetness without the metabolic rollercoaster of traditional table sugar.

Health Benefits & Sources

Why You Need It

  • Blood Sugar Control: It has a Glycemic Index (GI) of zero, meaning it doesn't spike insulin.
  • Dental Health: Unlike sugar, bacteria in the mouth cannot ferment it into acid, reducing cavity risk.
  • Low Calorie: Provides about 40% fewer calories than sucrose (table sugar).
  • Digestive Tolerance: It is absorbed slowly, which can be gentler than other sweeteners for some people (though moderation is key).

Deep Dive

Polyalditol acts as a 'bulk' sweetener. When you remove sugar from a recipe, you lose volume and texture. Polyalditol fills that gap. Because it is a sugar alcohol, the body does not treat it exactly like carbohydrates. It bypasses rapid digestion in the upper gut, moving further down to be fermented by gut bacteria. This slow absorption is why it has such a low glycemic response. For anyone managing diabetes or following a Keto lifestyle, it is a reliable alternative to maintain sweetness without metabolic disruption.

Natural Food Sources

While Polyalditol is most commonly used as a processed ingredient in 'sugar-free' gums and candies, the sugar alcohols it belongs to are found in nature. You can find trace amounts in:

Supplementation

Polyalditol is usually consumed as a food ingredient rather than a pill. However, if you are looking for it in supplement form (often labeled as Mannitol or Xylitol):

  • Usage: Common in powdered drink mixes or as a bulking agent in vitamin tablets.
  • Dosage: There is no Recommended Dietary Allowance (RDA). It is generally Recognized As Safe (GRAS) by the FDA up to specific limits, but individual tolerance varies.

Frequently Asked Questions

It is chemically produced (hydrogenated) from starch sources like corn or birch, but it is structurally similar to sugars found naturally in fruits.
No. Bacteria in the mouth cannot metabolize it into the acid that erodes tooth enamel.
Yes. It retains moisture well and provides bulk, making it excellent for cakes and cookies, though it won't brown (caramelize) like sugar does.
Yes. With a glycemic index of 0 and almost zero net carbs, it fits perfectly into a Keto diet.

Safety & Side Effects

Safety & Side Effects

Who should avoid it?

  • Dogs: It is highly toxic to dogs. Even small amounts can cause severe hypoglycemia, liver failure, or death. Keep products containing Polyalditol away from pets.
  • FODMAP sensitive individuals: If you have IBS, this can trigger bloating and gas.

Potential Side Effects:

  • Laxative Effect: Like all sugar alcohols, excessive intake (usually over 20-30g) can cause diarrhea or stomach cramping.
  • Transient Bloating: Due to fermentation in the lower gut.
