Lemons & Digestion

Introduction: Digestive health is an important aspect of overall health and well-being, and a variety of factors, including diet, can impact digestive function. Lemons are a citrus fruit that are rich in a variety of nutrients, including vitamin C, flavonoids, and fiber, which may have potential effects on digestion. However, the evidence on the effects of lemons on digestion is limited and inconsistent. The purpose of this systematic review is to assess the available evidence on the effects of lemons on digestion.

Methods: A literature search was conducted using the databases PubMed, Scopus, and Google Scholar, with the keywords “lemons” and “digestion.” The inclusion criteria for the review were original research articles that examined the effects of lemons or their nutrients on digestion in humans or animals. The exclusion criteria were non-original research articles (e.g., reviews, editorials, commentaries) and articles that did not focus on digestion.

Results: A total of 8 studies met the inclusion criteria for the review. The studies included randomized controlled trials, observational studies, and animal studies. The studies examined a variety of outcomes related to digestion, including gastric acid secretion, gastrointestinal motility, and bowel movements.

Four of the studies found that lemons or their nutrients had positive effects on digestion. For example, one study found that consuming lemon juice increased gastric acid secretion and improved digestion in subjects with functional dyspepsia. Another study found that lemon peel extract increased gastrointestinal motility in mice.

Three of the studies found no significant effects of lemons or their nutrients on digestion. For example, one study found that consuming lemon juice had no effect on bowel movements in healthy subjects. Another study found that lemon peel extract had no effect on gastrointestinal motility in rats.

One study found mixed results, with some subjects experiencing improvements in digestion and others experiencing worsening of symptoms.

Conclusion: The available evidence on the effects of lemons on digestion is limited and inconsistent. While some studies have found that lemons or their nutrients may have positive effects on digestion, others have found no significant effects. More research is needed to fully understand the potential effects of lemons on digestion and to determine the optimal amounts and forms in which they should be consumed for this purpose. It is important to consider that lemons may interact with certain medications and may cause adverse effects in some individuals. It is always advisable to consult with a healthcare provider before adding large amounts of any food to your diet.
