Lemon and vinegar are very acidic, and drinking too much on an empty stomach will hurt your stomach.

Lemonade is rich in vitamins, has a beauty effect, can prevent and eliminate skin pigmentation, and has a whitening effect. Because the pH value of lemon is as low as 2.5, people with hyperacidity and gastric ulcer should not drink lemonade.

Extended data:

Lemon is rich in vitamin C, which has many functions, such as anti-bacteria, improving immunity and assisting the formation of bone collagen. Drinking lemonade often can supplement vitamin C.

In addition to resisting bacteria and enhancing immunity, it also has the effects of stimulating appetite, promoting digestion, promoting fluid production and quenching thirst, and relieving summer heat. Add warm water and salt to lemon juice, drink it and cough up the thick phlegm accumulated in your throat.

If you drink lemonade an hour before going to bed at night, the effect will be better. Using the time absorbed by the body at night, you can see the whitening effect the next day and make the skin more delicate.
