Drinking lemon juice without diluting it with water or any other thing is good for health in what ways?

Lemons are filled with vitamin C, which boosts your immune system and prevents you from getting infections, making this a good practice if you are susceptible. However, i would advise cleaning your teeth immediately afterwards to prevent the acid attacking your teeth. ANSWER: Lemons are indeed a source of Vitamin C (ascorbic acid), and may be related to immunological defense. More important is that its a required nutrient and without it, eventually, you cannot survive. However, there is no benefit to taking lemon juice alone without water. Also, there are many other Vit. C sources. Dilution makes no real difference in this case at all
