Erythritol: how healthy is the sugar substitute?

Erythritol as a sugar substitute

Low-sugar and low-carb diets are popular nutritional trends. So, it’s no surprise that interest in sweeteners is high. Erythritol, a sugar alcohol or sugar substitute, is one such sweetener. Erythritol is practically calorie-free and is not thought to pose a risk to our health. In terms of both taste and texture, erythritol is almost identical to sucrose – our household sugar.

Erythritol and diabetes?

The sweetening power of erythritol is about 60-70% of that of conventional sugar. However, the sugar alcohol provides very little energy (at about 20 kCal/100g, twenty times less than sucrose) and is not insulin effective. This means that when it's absorbed by the body, no insulin is released into the blood. Erythritol can therefore be incorporated into the eating plans of diabetics or people in risk groups.

Erythritol as a sugar substitute

Dissolved in water, erythritol leaves a cooling taste on the tongue – making it ideal for a refreshing low-calorie summer drink. It can also be used for baking, and for making desserts. Combined with protein-rich foods such as quark or yoghurt, it is highly satisfying and staves off hunger.

How much erythritol is needed as a sugar substitute?

If erythritol is used for sweetening, and the same sweetness as granulated sugar is required, the quantity must be increased by about a quarter. Where a recipe calls for 100 grams of sugar, this can be replaced with around 125 grams of erythritol. Erythritol can also be used to gradually become accustomed to a less sweet taste.

How healthy is erythritol?

Like other sugar alcohols, erythritol is classified as safe for our health. The body absorbs 90% of the sugar substitute through the small intestine and excretes it unchanged via the kidneys. This greatly reduces the level of flatulence associated with other sugar alcohols, since these are mainly caused by the bacterial fermentation of sweeteners in the large intestine.

Avoid erythritol if you have one of these intolerances

To be on the safe side, people with sensitive intestines, fructose or histamine intolerance should avoid sugar substitutes, for although erythritol is classified as a safe food additive, no long-term studies on its effect have yet been made.

What is erythritol made of?

Erythritol is produced through fermentation. And, as with many biotechnological processes, genetic engineering methods can be used – for example, in the maize used as the starting product or the fungal cultures required for fermentation.
