暢飲檸檬水排毒助消化

There is a long-standing belief that drinking lemon water can aid digestion and even help with digestion.Detoxify the bodySo, are these claims scientifically based? Gastroenterologist and hepatologist Dr. Wu Jia-en provides a professional explanation: Lemon water can indeed help with digestion by increasing stomach acidity and lowering the pH value in the stomach, but it cannot change the pH value of the blood. Therefore, the so-called "detoxification" effect is unfounded.

Dr. Wu Jiaen further explained the relationship between stomach pH and digestion: In an empty stomach, the pH of the human gastrointestinal environment is approximately between 5 and 6. After eating, the stomach begins to secrete gastric acid. Usually, after 45 minutes, as food mixes with gastric juices, the stomach pH gradually drops to 3, at which point the digestive process officially begins. Common lemon juice and grapefruit juice, whether concentrated or diluted, have pH values of approximately 2 and 3 respectively, which are similar to the acidic environment of the stomach during digestion. Furthermore, lemon juice contains...Vitamin CThe two work together and can indeed have a certain auxiliary effect on digestive function.

However, it's important to note that people with acid reflux should not drink large amounts of lemon juice. The acidity of lemon juice may further stimulate stomach acid secretion, worsening symptoms. Besides lemon water, some commercially available sour preserved fruits (such as preserved plums) can also aid digestion, but these foods do not contain...Vitamin CIt may also contain high levels of sugar, and excessive consumption can easily lead to a "high sugar trap," potentially impacting health.

Regarding the widely discussed claim that "lemon water can detoxify the body," Dr. Wu Jiaen clearly stated that this claim lacks scientific support. From the perspective of the human body's metabolic mechanism, lemon water is ultimately excreted through the urinary tract and does not enter the bloodstream to regulate the blood's pH balance. Therefore, it cannot achieve the effect of "washing away toxins" or "detoxifying."
