Sugar alcohols are those secretive, mystery sweeteners floating in your “sugar-free” candy and dental products. Are they healthy substitutions or hidden villains? It’s time for a sweet revelation!

You’ve probably digested this sweet alcohol if you have ever binged on “sugar-free” candies or chewed on xylitol-infused gum. These sweeteners have a bad rep for wreaking havoc on your gut, but they’re also pretty famous for being good for your teeth and low in calories. 

So what’s the deal? Are they a sneaky sugar bomb or harmless alternative?

Let us look through these alcohols, trace their sources, understand how they act in our organisms, and extract sweet facts from the ocean of bitter fiction.

What Are Sugar Alcohols?

They have neither sugar nor alcohol in them. Now, that’s an identity crisis! They are a kind of carbohydrate. Their chemical structure is similar to sugar and alcohol, but it is neither. 

Polyols occur naturally in some fruits and vegetables but are also added to most processed foods.

Common types are xylitol, sorbitol, maltitol, and isomalt. The production starts with drawing the initial material from either sugars or starches, then undergoes a chemical process to change its makeup, resulting in sweetener products. 

This will yield sweetening agents similar in taste to sugar but containing fewer or zero calorie sugar and less easily absorbed into the body.

Types And Sources Of Sugar Alcohols

There exist many types, each having its special nature. Here are some of the most common ones and their sources:

Types Of Sugar Alcohols

1. Erythritol

They happen to be the popular guys in this gang. You will probably see it in most sugar-free and low-calorie foods because it has a high sweetness level and virtually no calorie count. 

They do occur naturally in some fruits and fermented foods, although commercial amounts come from glucose. It has a clean sweet taste, and your body absorbs it well. 

The extent of absorption means that it doesn’t tend to react in the gut like other sugar alcohols.

2. Maltitol

Maltitol, however, is like the troublemaking cousin. It has a very close taste and feel to regular sugar, so manufacturers like it a lot—if not more than others on their favorite list. 

Most sugar-free candies, chocolates, and baked goods contain maltitol. But unlike erythritol, maltitol poorly absorbs into a system and may cause some gastrointestinal discomfort after its overconsumption. 

So, enjoy that sugar-free chocolate—as if you need reminding—but not too much!

3. Mannitol

Mannitol is like the classy aunt of them all. Pharmaceutical companies commonly use it as a sweetener with fewer calories in chewing gums and candies.

Mannitol is a somewhat less sweet version of sugar, yet it gives an excellent cooling effect, so it’s just perfect for minty freshness in your breath. 

It is also added to some medicines to enhance their absorption and taste.

4. Sorbitol

Sorbitol is like the older sibling that does everything right—pervasive, and applied in a thousand ways: in sugar-free candies and chewing gums, in baking, and even in toothpaste and mouthwash. 

Since sorbitol is partially absorbed in the body, it can be a laxative if taken in excess.

5. Xylitol

Now, this is the star athlete among these. It looks and tastes quite like sugar, but has fewer calories in it. Some familiar applications of it are sugar-free chewing gums and candies. 

It is even used by some dental products, supposedly able to lower the risk of tooth decay. 

Perhaps most importantly, though, be sure to keep the xylitol away from your furry friends, as this substance is toxic to dogs.

6. Hydrogenated Starch Hydrolysates (HSH)

Now, this one’s a mouthful, both literally and figuratively. Hydrogenated starch hydrolysates stand for a group of sugar alcohols created when starch gets broken down and then hydrogenated. 

Manufacturers use them in a variety of food products, from ice cream to baked goods to even some nutritional supplements. 

It is about as sweet as sugar, but it has a bit of a distinct mouthfeel.

7. Isomalt

Isomalt sounds a bit like that cousin who always wears shades, even inside. It’s a sugary alcohol, prepared with sucrose, and really quite sugar-like in taste and texture. 

Basically, it is normally applied in sugar-free candies, chocolates, and all confectionery products. 

It shows a very poor crystallization ability, hence the smooth texture, while showing rather low hygroscopicity—that’s to say, it doesn’t attract moisture—so your treats will stay nice and crispy.

Nutritional Information

This sweetener provides fewer calories than sugar, ranging from 0.2 to 3 calories per gram compared to 4 calories per gram for sucrose. They are also slower to absorb in the body, which means they have a lesser impact on blood sugar levels.

The following table, from the International Food Information Council Foundation, gives the number of calories for each of them.

Sugar Calories (per gram)
Sorbitol2.6 g
Mannitol1.6 g
Maltitol2.1 g
Erythritol0–0.2 g (accepted value differs in certain countries)
Xylitol2.4 g
Lactitol2.0 g
Isomalt2.0 g
Hydrogenated starch hydrolysates3 g

However, it’s important to note that sugar alcohols are not a “free pass” when it comes to calories and carbohydrates. They still provide energy and can affect blood sugar, just to a lesser degree than regular sugar.

Possible Health Benefits

Now, here’s why you might want to ask these sugar alternatives out on a date in your life:

  • Fewer Calories Consumed: It provides a sweet fix without the heavy calorie load attached to sugar. This alone can prove to be very instrumental in weight management and health in general.
  • Dental Health: It actively reduces the risk of tooth decay and improves dental health as a specific appetite resource. This is because it prevents the growth of cavity-forming bacteria in the teeth and may even remineralize tooth enamel.
  • Blood Sugar Control: Unlike regular sugar, it has minimal effects on blood sugar. This makes them a much safer choice for diabetics and those who have an adverse reaction to blood sugar changes.
  • Gut Health: Since some sugar alcohols, especially erythritol, and xylitol, are somewhat indigestible, they really act as dietary fiber and come with prebiotic properties. Put simply, they will feed the good bacteria in your intestines and help make your gut healthier.
  • Lower Obesity and Type 2 Diabetes Risk: It may be related to a lower risk of obesity and type 2 diabetes through management of body weight and regulation of blood sugar levels.
  • Longer Shelf Life: The food manufacturers are using this sweetener to achieve stability and prolonged shelf life in their products. This property is useful loosely, particularly in bakery and sweet products.
  • Flavor Enhancement: It enhances flavor from other applied sweeteners, hence proper use in many foodstuffs.
  • Humectancy: Being humectants, sorbitol, and other sweeteners help in the holding of moisture in food products so that they remain softer and fresher for a longer period.

Risks Of Taking Sugar Alcohols

Now, let’s get down to the elephant in the room—or, rather, the tummy trouble, if you will.

Risks Of Taking Sugar Alcohols
  • Gastrointestinal Distress: The most common side effect is digestive problems. Since they aren’t completely digestible, they can easily cause gas, bloating, cramps, and diarrhea in large consumption.
  • Malabsorption And Lactic Effect: Unabsorbed sugar alcohols in the small intestine might draw water into the colon, which can cause a laxative effect. This can be of major concern to individuals with sensitive guts or IBS.
  • Weight Gain: Even though they are low-calorie sugars, if they are taken in excessive amounts, they can be one of the factors for gaining weight. Remember, “sugar-free” doesn’t mean “calorie-free.”
  • Misleading Marketing: When sugar substitutes are added to food, the manufacturers give the label as being “sugar-free.” It sometimes misleads consumers because, though they actually contain less sugar than normal foods, these types of sweeteners do provide some level of caloric intake and raise blood sugar levels.
  • Possible Overconsumption: Sugar-free products, in a way good, can sometimes be the cause of overindulgence. Don’t assume you can consume the entire box just because it’s labeled “sugar-free.” Calories count!
  • Allergic Reactions: Although rare, people can be allergic or sensitive to certain sugar alcohols, which may behave as skin rashes, urticaria, or even anaphylaxis.
  • Impact On Gut Microbiome: It acts as prebiotics for some and has a hostile effect on the gut microbiome in others. This research is still developing, and full effects are not yet known for long-term use.
  • Higher Levels Of Mercury Possibly Present: This is true for sugar alcohols like xylitol, which may contain trace amounts of mercury owing to the manufacturing process. While the levels are very negligible, it is something to be aware of.

How Can You Tell If A Food Contains Sugar Alcohol?

Sugar alcohols are sneaky. Very often, they will hide in plain sight in those so-called “sugar-free” or “diet” products and try to pass as the healthier alternatives. One has to be a kind of detective, really, to find them and read food labels.

  • Ingredient List: This is your best friend. There’s no rocket science involved in remembering the names of the sugar alcohols previously mentioned: erythritol, maltitol, mannitol, sorbitol, xylitol, HSH, and isomalt.

    Most of the time, we list them by their names, but other times, they might hide under the umbrella term “polyols.”
  • Nutrition Facts Panel: Very often, the nutrition facts panel will discuss which sugar alcohol is being used. It may say something like, “Contains sorbitol” or “mannitol sweetened.” This is the best giveaway.
  • Claims And Marketing Noting Up-Front The Claims On The Packaging: If it’s “sugar-free,” “low-calorie,” or “diet”—there’s a good chance sugar alcohols are involved. Marketers seem to use these terms almost synonymously.
  • Sweet Taste, Less Calories: If you have an induction that tastes sweet but has fewer calories than you would otherwise anticipate, then sugar alcohols are more than likely to be responsible.

    They provide the sweet hit without the caloric punch of sugar.
  • Sugar Alcohol Content Disclosure: This is required on the label in some countries, such as in the US. Certainly, look for this, as it is a dead giveaway that sugar alcohols are present.

A Word From Fitelo

There you have it—sugar alcohols, a pretty interesting group of characters that give the most in benefits and problems. They are neither Sugar’s evil twin siblings nor sweetener world angels. Everything in life, like other things, is a matter of being in moderation and balance.

Sugar alcohols are great alternatives for those who wish to lower their sugar intake or have medically controlled diets. Not forgetting that in excess, it may cause some inconveniences or even discomfort, especially during the first weeks of using the sweetener by new people to the game.

Sweetener options complicate the world out there; they’re only one piece of the pie. Education and awareness are important in every domain that touches health and diet. So the next time you reach for that “sugar-free” treat, you’ll know just what you’re getting yourself into!

Frequently Asked Questions

Is Sugar Alcohol Healthier Than Sugar?

They are a type of sugar that offers more significant health benefits than regular sugar, such as fewer calories and a very minor rise in blood sugar levels. It, in fact, promotes dental health. Therefore, in this sense, they are excellent substitutes in the case of diabetes or for improving dental health. On the other hand, they come with their set of risks.

How Much Sugar Alcohol Is Ok Per Day?

Consume it in limited amounts. Several studies have shown that consuming up to 10-15 grams per day is generally safe and does not cause gastrointestinal distress.

Is Sugar Alcohol Bad For Weight Loss?

They can help in weight loss as they have fewer calories as compared to regular sugar. This can be a good way of reducing empty calories and keeping track of total calorie intake.
