Low-digestible carbohydrates, like fiber and resistant starch, are increasingly used in processed foods for health benefits. Understanding their types and intake is key to managing potential gastrointestinal effects.
Area of Science:
- Nutrition Science
- Food Chemistry
Background:
- Low-digestible carbohydrates (LDCs) are incompletely absorbed in the small intestine and fermented in the large intestine.
- Common LDCs include fiber, resistant starch, and sugar alcohols.
Purpose of the Study:
- To review the range of LDCs in food products.
- To provide guidance on identifying LDCs in foods and beverages.
- To offer recommendations for LDC intake.
Main Methods:
- Literature review of LDCs in food products.
- Analysis of LDC properties and health implications.
- Synthesis of information on LDC identification and intake.
Main Results:
- LDCs offer health benefits such as reduced caloric content and minimal impact on blood glucose.
- Increased prevalence of LDCs in processed foods due to their benefits.
- Gut fermentation of LDCs can lead to gastrointestinal effects, particularly at higher intakes.
Conclusions:
- Consumers can benefit from understanding LDCs for informed food choices.
- Managing LDC intake is important for maximizing health benefits and minimizing digestive discomfort.
- Further research into optimal LDC intake levels is warranted.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
