Where the lemon first came into being is not completely clear — however, its believed to have originated in northern India over a thousand years ago.

The lemon is a cross between several other citrus fruits, probably the thick-skinned lemon and the bitter orange.

The lemon is first clearly mentioned around 1000 AD. At that time, it was known in the Mediterranean region as well as in China.

From the 13th century onwards, the lemon gets cultivated in Spain and southern Italy.

The sour lemon juice already played a specific role in the kitchen of the Middle Ages.

In the 16th century, the cultivation of all kinds of citrus plants became very popular in Germany as well. In many cities, so-called orangeries get built, gardens in which citrus plants were getting cultivated. In winter, the sensitive plants were getting brought into specially made houses.

Nowadays, orangeries often provide rooms for cultural events.

Nowadays, the lemon is cultivated in many warm regions of the world and is an essential fruit in world trade because of its fruity acidity.

The acid in lemon can attack the enamel and make the teeth sensitive. Run your tongue over your teeth and test if the surface feels rough. If it does, it could be due to broken enamel. If you don’t want to do without lemon in the water, experts recommend drinking the water through a straw so that the water has less contact with the teeth.

The sour lemon juice can trigger the so-called gastroesophageal reflux disease, whereby the gastric acid runs back into the esophagus. Symptoms can include severe heartburn, nausea, and vomiting.

Among others, the E. Coli virus, which can cause vomiting and diarrhea. Minimize the risk of infection, always wash the rind of the lemon with hot water and preferably with a brush. You can eliminate the threat, squeeze the juice of the lemon, and put it into the water instead of a piece with the peel.

Lemon Juice Diet Benefits and Side Effects

Is a lemon juice diet healthy?

There is no question that lemons are healthy because everyone who has ever had a cold will have certainly gotten back on track with tropical fruit. Lemons are known to contain a lot of vitamin C, and this is said to be responsible for the fact that the kilos fall. Vitamin C stimulates the burning of fat in the body and ensures a fast metabolism, and that is all that a diet should achieve.


There are good reasons why doctors advise against a lemon juice diet

  • For one thing, no matter how insensitive the stomach is, it will not tolerate this diet over a long period. The citric acid attacks the stomach walls, and it can lead to excruciating stomach cramps. It’s especially the case if you decide to go for the variant with cayenne pepper. The sour lemon and the hot pepper slow down the hunger but are – from a health point of view – a rather dangerous combination.
  • If you drink a lot of lemon juice, you will eventually feel a numb feeling in your mouth, because even the sensitive mucous membrane of the mouth cannot withstand the acidity of the lemons for long.
  • Besides, drinking a lot during a lemon juice diet means that one has to go to the toilet very often due to a large amount of liquid. So if you have to stand in a shop or sit in an office all day, you might want to try a different diet.


You should pay attention to this if you want to eat lemons pure

As a rule, there is nothing to stop you from consuming lemons, as they offer numerous health benefits. However, it is essential to check beforehand whether you can tolerate the fruit pure.

  • Some people have problems with the acid contained in the citrus fruit.
  • Lemon can lead to stomach aches, among other things. At the same time, the enamel can get threatened, which is why you should brush your teeth about an hour after eating a lemon.
  • Therefore, try only a small piece first and examine how your body reacts to the acid.
  • If you don’t find any problems, you can tolerate the lemon, and there is nothing to stop you from eating it. 
  • Irritation of the skin and mucous membranes
  • Allergies should be dosed carefully during external treatment
  • Photosensitization may cause irritation or unpleasant spots on sensitive skin due to uneven tanning
