Choose fresh lemons, which are especially fragrant. The aroma of dried lemon is not so strong, and there is less vitamin C in dried lemon. Pay attention to rubbing with flour before eating, then rub the epidermis with a handful of salt to remove residual pesticides and wax, and finally wash it twice with clear water. Fresh lemon should be peeled and cut into 2-3mm thin slices, because peeling is also good for health, and drinking it in hot weather can quench your thirst.
The water temperature is 60-70℃. The water soaked in lemon is too cold to stimulate the fragrance of lemon; If brewed with boiling water, it is easy to destroy VC, and more bitter substances will be dissolved, which will affect the taste and nutrition.
Beauty lovers should never put lemon on their faces, because lemon contains acetic acid, which will make your skin sensitive.
No matter how good the food is, you can't eat it recklessly. Lemon is no exception. Drinking a lot of lemons will hurt your stomach. So drink lemonade in moderation, not more than 1000 ml per day. In addition, because the pH value of lemon is as low as 2.5, people with hyperacidity and gastric ulcer should not drink lemonade.
Because lemon is a light-sensitive food, if you go out to bask in the sun soon after drinking it, your skin will easily get spots and even turn black. Drinking lemonade in the evening is better for whitening. If you drink lemonade an hour before going to bed at night, the effect will be better.
