Tagatose is a sugar similar to fructose
Tagatose is a simple sugar (monosaccharide) with the same formula as fructose (C6H12O6) but with a different arrangement of atoms. The exact chemical name is D-tagatose.
- Calories per gram = 1.5-2.4
- Glycemic index (GI) = 3
- Sweetness, relative to sucrose = 75-92%
- Net carbohydrates = 3%
Tagatose is an artificial sweetener produced from whey
Tagatose as a food additive is artificially produced from lactose, which is obtained from whey and this from cow’s milk. According to some sources it is still safe to consume even if you are lactose intolerant. During processing, the lactose is broken down by an enzymatic process and then the product is crystalized into the white powder that is ready to be eaten.
Tagatose Calories and Net Carbs
Tagatose has almost no effect on blood glucose levels, so it does not contribute to net carbs and should be also distracted from the total carbs. Tagatose provides only 1.5 Calories (kilocalories) per gram (according to food labels in the United States) or 2.4 kcal/g (food labels in European Union), so is considered a low-calorie sweetener. Tagatose is one of the “allowed” sugars in low-carbohydrate diets.
Tagatose has a clean, neutral sweet taste, and is 75-92% as sweet as sucrose.
In the European Union, tagatose is considered a novel food – a food that was not used in considerable amounts in the EU before y. 1997, so its long-term safety is not known. D-tagatose is Generally Recognized As Safe (GRAS) by the US Food and Drug Administration (FDA). The World Health Organization’s Joint Expert Committee on Food Additives (JECFA) has left Acceptable Daily Intake for tagatose as “ADI unspecified,” which means even high intakes are not expected to have long-term toxic effects.
Tagatose and Diabetes
- Tagatose does not significantly raise blood glucose and insulin levels in healthy individuals and those with diabetes 2.
- Tagatose consumed before a carbohydrate meal attenuates the rise of blood glucose levels after the meal. Tagatose is currently being studied as a glucose-lowering drug for diabetes 2.
Glycemic Index (GI) of tagatose is only 3, which means it raises blood sugar levels only by 3% compared with glucose.
