Dr. Saurabh Sethi, a gastroenterologist trained at AIIMS, Harvard, and Stanford universities, states that 75% of adults are chronically dehydrated. Lemon makes water more appealing, which helps digestion, energy, and focus. He also states that one lemon offers 35 mg vitamin C, which is about 40% of our daily needs. It also boosts immunity, collagen, skin health, and iron absorption. He also informs that lemon water supports digestion, especially in low stomach acid cases. The mild acidity may stimulate gastric juices and bile flow. In his post he has also mentioned that up to 20% of people with GERD say citrus worsens the symptoms. He suggests avoiding lemon water on an empty stomach, if you notice burning or bloating. Also, lemon juice has a pH of-2 , which is very acidic. He suggests drinking it in one sitting with straw and rinse with plain water. He also clarifies that the internet overphypes it and your kidneys and liver are better detoxifying agents. Lemon water just supports hydration and digestion, not magic cleansing.
