What do you understand by the term non-available carbohydrate? Give its sources and functions.

Non-available Carbohydrate:

Definition: Non-available carbohydrate refers to the portion of carbohydrates in food that cannot be digested and absorbed in the small intestine, passing through the digestive tract unchanged. This includes dietary fiber and resistant starch, which are not broken down by human digestive enzymes.

Sources: Non-available carbohydrates are found in plant-based foods such as fruits, vegetables, whole grains, legumes, and nuts. These foods contain varying amounts of dietary fiber and resistant starch, which contribute to the non-available carbohydrate content.

Functions:

1. Digestive Health: Non-available carbohydrates, particularly dietary fiber, play a crucial role in promoting digestive health by adding bulk to the stool, aiding in bowel movements, and preventing constipation.
2. Blood Sugar Control: Non-available carbohydrates, especially resistant starch, can help regulate blood sugar levels by slowing down the absorption of glucose from the digestive tract.
3. Weight Management: Foods high in non-available carbohydrates are often low in calories and can help increase satiety, promoting a feeling of fullness and potentially aiding in weight management.
4. Heart Health: Dietary fiber from non-available carbohydrates can help lower cholesterol levels and reduce the risk of heart disease by binding to cholesterol in the digestive tract and aiding in its elimination.
5. Gut Microbiota: Non-available carbohydrates serve as a source of nutrition for beneficial gut bacteria, promoting a healthy balance of gut microbiota and supporting overall gut health.

Conclusion:
Non-available carbohydrates, including dietary fiber and resistant starch, are an essential part of a healthy diet. They play a crucial role in promoting digestive health, regulating blood sugar levels, aiding in weight management, supporting heart health, and maintaining a healthy gut microbiota. Incorporating a variety of plant-based foods rich in non-available carbohydrates into the diet can help support overall health and well-being.
