Nectarines, a smooth-skinned variety of peach, are a popular stone fruit enjoyed for their sweet, juicy flavor. They can aid in bowel movements primarily because of their unique nutritional makeup. Like many fresh fruits, nectarines contain compounds that actively support the digestive system and promote regularity. This effect is directly linked to the fruit’s fiber and water content.
Key Nutritional Components Aiding Digestion
A single medium-sized nectarine contributes approximately 2.4 grams of dietary fiber, which is a mixture of both insoluble and soluble types. The fruit is also composed of a high percentage of water, required for the proper formation and passage of stool. Nectarines contain specific carbohydrates that influence digestion, including the sugar alcohol sorbitol. Sorbitol is known for its osmotic effect, drawing water into the large intestine. Additionally, nectarines contain fructans, which are fermentable carbohydrates classified as a type of FODMAP.
Mechanisms Supporting Bowel Regularity
The insoluble fiber found in nectarines does not dissolve in water and passes through the digestive tract intact. This undigested matter adds bulk to the stool, which stimulates the muscular contractions of the intestinal walls. This increased bulk accelerates the transit time of waste through the colon.
The soluble fiber component absorbs water in the gastrointestinal tract to form a gel-like substance. This action helps to soften the stool, making it easier to pass. Soluble fiber also serves as a prebiotic, feeding beneficial gut bacteria, which contributes to a healthy microbial environment in the colon.
The high water content of the fruit helps to hydrate the stool directly, providing a lubricating effect for smoother passage. The osmotic action of the sorbitol draws extra fluid into the colon, which aids in softening the stool. The combined effect of these components promotes coordinated gut motility, the physical movement of the intestines necessary for regular evacuation.
Moderation and Digestive Considerations
While nectarines benefit digestive health, consuming too many too quickly can lead to uncomfortable side effects. A rapid increase in fiber intake may cause temporary gas, bloating, or abdominal cramping. This occurs because gut bacteria require time to adjust to processing the higher volume of fermentable material.
The fructans and sorbitol content can be problematic for individuals with sensitive digestive systems. For people with conditions like Irritable Bowel Syndrome (IBS), these fermentable carbohydrates may trigger symptoms such as diarrhea due to their osmotic effect and gas production. It is advisable to incorporate nectarines into the diet gradually, especially for those not accustomed to high-fiber intake.
