From the Guidelines
Drinking lemon water consistently can provide several health benefits, including supporting immune function, aiding digestion, and promoting hydration, as long as it is consumed in moderation and with consideration of potential dental erosion and digestive issues 1. The health benefits of lemon juice in water are numerous, but it is essential to consider the potential risks and limitations. Adding fresh lemon juice to water provides vitamin C, which supports immune function and acts as an antioxidant that helps protect cells from damage. The citric acid in lemon juice may aid digestion by stimulating stomach acid production and can potentially help prevent kidney stones by increasing urine citrate levels. Some key points to consider when drinking lemon water include:
- Promoting hydration since the pleasant flavor encourages people to drink more water throughout the day
- Supporting weight management when substituted for higher-calorie beverages
- Potential dental erosion due to the acid in lemon juice, which can be mitigated by rinsing the mouth with plain water afterward or drinking through a straw
- Potential digestive issues, such as acid reflux, which may require consultation with a healthcare provider before making lemon water a daily habit It is also important to note that the provided evidence does not specifically address the health benefits of lemon juice in water, but rather discusses the recommendations for fruit juice consumption in infants, children, and adolescents 1, and the standards of care in diabetes 1. However, based on general knowledge and the available evidence, the recommended approach is to squeeze half a fresh lemon into 8-12 ounces of water (warm or cold) and drink it daily, preferably in the morning, while being mindful of the potential risks and limitations 1.
From the Research
Health Benefits of Lemon Juice in Water
There is no direct evidence to support the health benefits of lemon juice in water consistently. However, the provided studies discuss the effects of acidic beverages and foods on dental health.
Dental Erosion and Acidic Beverages
- Frequent consumption of acidic beverages and foods can lead to dental erosion and erosive tooth wear (ETW) 2.
- Vitamin C and natural fruit juices, including lemon juice, are associated with a higher risk of ETW 2, 3, 4, 5.
- The acidity of vitamin C tablets and other acidic substances can demineralize tooth enamel, leading to dental erosion 3, 4, 5.
Erosive Potential of Acidic Substances
- The erosive potential of acidic substances is influenced by factors such as pH, buffer capacity, titratable acidity, and calcium and phosphate concentrations 2, 6.
- The addition of calcium can reduce the erosive potential of acidic substances, while phosphate has no significant effect 6.
- Fluoride mouthwash can exacerbate enamel demineralization when used immediately after exposure to acidic medications 5.
