Digestive benefits do not come from apples as many people think
Boiled apple juice is made by simmering sliced apples in water, then filtering out the residue and drinking the remaining water. This method is based on the viewpoint of traditional Chinese medicine that warm food can support bowel movements.
However, according to sports nutrition expert Jordan Hill, an expert at Top Nutrition Coaching, USA, boiled apple juice is difficult to create a significant impact on the digestive system. He analyzed that the benefits of whole apples mainly come from soluble fiber, insoluble fiber and polyphenol compounds. When apples are heated and the flesh is removed, most of the fiber is retained in the pulp, and polyphenols are also significantly reduced.
Fiber plays a role in increasing stool volume, nourishing the gut microbiota and supporting regular diarrhea. Therefore, drinking filtered apple juice cannot bring the same effect as eating whole apples or using less processed apple products.
The "warmth" and hydration factor are the key
According to Kezia Joy - a nutritionist and medical consultant at Welzo, UK, the effect is likely to come from the temperature and amount of water added. Warm drinks can stimulate bowel movements, while providing enough water helps stools become softer and easier to excrete.
This means that not only apple juice, but any type of warm water can partially support if the body is dehydrated. Boiled apple juice is not a solution for treating chronic constipation or digestive diseases.
However, replacing sugary drinks with boiled apple juice can help reduce daily sugar intake. Apples still contain vitamin C and antioxidant polyphenols; a small amount of these compounds can dissolve in water. However, to improve sustainable digestion, experts recommend prioritizing eating enough fiber from whole fruits, green vegetables and whole grains, while maintaining the habit of drinking enough water every day.
