Nevertheless, not until the 11th century did lemon make its first appearance in Europe and Africa.

Then, lemon came to the Americas thanks to Christopher Columbus’s voyage.

Nowadays, its production becomes world-wide, with the United States being the largest producer, followed by Italy and Spain.

Few people eat lemon directly because of its sourness. Instead, lemon is often used in the form of the juice or combined with other ingredients to improve the flavor.

For long, lemon has been well-known to be abundant in vitamin C and many other important nutrients for human health.

This article will examine lemon nutrition facts first.

The main content of lemon is water that makes up for nearly 90 percent (1).

Carbohydrates also have a considerable amount with approximately 10 percent, whereas there are such moderate amounts of protein and fat in a lemon.

One of the most important elements of lemon is fiber which is responsible for many lemon health benefits (2).

Besides, when it comes to lemon, it is necessary to think of vitamins immediately.

Vitamin B6 in lemon will aid the transformation of foods into the energy for the body.

There is a close association between lemon nutrition facts and lemon health benefits.

Below are top 10 health benefits of lemon that are the results of many-year research to find out how beneficial this citrus fruit can be to human health.

1. Kidney Stone Prevention

Kidney stones are the result of the crystallization of waste products in our kidneys. Throughout time, they accumulate and develop into small lumps.

Kidney stones are very annoying and they appear repeatedly.

Fortunately, you can get rid of them with a simple ingredient, lemon. To reduce the formation of kidney stones is also one of the best health benefits of lemon.

The amount of citric acid in lemon can enhance the urine pH level and volume. This makes it less favorable for kidney stones to develop (3) (4).

In fact, the real efficiency of lemon juice on preventing kidney stones still needs further examining.

Bottom Line: Lemon juice is effective in lowering the risk of kidney stones, but more studies are still needed.

2. Digestion

The majority of fiber found in lemons is soluble which constitutes many health benefits of lemon, one of which is to enhance the digestive system.

Soluble fiber is claimed to foster the gut health and impede the way the starches and sugars are digested (7) (8).

Nevertheless, these lemon health benefits are effective only when you consume its skin and pulp.

Therefore, if you use lemon juice, you will not benefit from lemon’s high content of fiber.

Bottom Line: With a great amount of soluble fiber, lemon can promote the digestion, but only when you consume the pulp and skin.

3. Anemia

Anemia refers to the shortage of red blood cells and one of the main causes for this problem is the deficiency of iron.

One of the best health benefits of lemon is to fight against anemia effectively.

It is true that lemon can provide your body with a certain amount of iron, but what is really outstanding about lemon is the fact that it aids the way your body absorbs iron from foods (9) (10).

Some studies reveal that lemon is useful to help you stop putting on more weight thanks to its content of plant compounds (11) (12).

In an experiment, the extract of polyphenols from lemon peel was given to mice.

The result showed that these mice were less likely to gain weight and fat than others (13).

Vitamin C, however, is not the only contributor.

Plant compounds and fiber take part in the prevention against cardiovascular disease as well (15) (16).

However, it is possible that this fruit will lead to some unwanted situations if you consume it in the wrong way.

The excessive intake of lemon juice might cause you to experience some annoying problems

Firstly, while it is true that lemon has positive effects on our dental health in general, too much lemon water may supply an overload of acid in the mouth.

As a consequence, you might worsen the tooth erosion.

This is the main reason for many other health problems.

Besides, lemon water is a feasible cause for heartburn.
