THE ADVANTAGES AND DISADVANTAGES OF LEMON WATER
A glass of water with fresh lemon juice is for many people the perfect way to start the day. However, is it really as healthy as they think?
Below we discuss the advantages and disadvantages of lemon water, according to scientific research.
1. Source of vitamin C
Lemons are a source of vitamin C. Studies have shown that vitamin C strengthens the immune system and protects against skin aging, infections and heart disease. Keep in mind that the vitamin C content of lemon juice may vary. This depends, among others, on the difference in methodology, climate, fertilization, variety, stage of development and the conditions of storage. One study has demonstrated that the vitamin C content of fresh lemon juice is 54.74 mg/100 ml. However, another study has revealed that the vitamin C content is only 12,68 mg per 100 ml. The results of these studies can be found in Molecules and Biological Forum-An International Journal.
2. Prevention of weight gain and improvement of insulin resistance
Researchers of the Humboldt University in Berlin have discovered that drinking 500 ml of water increases the metabolism of healthy normal-weight adults by 30%. The increase starts within ten minutes and reaches a maximum after 30 to 40 minutes.
A study published in the Journal of Clinical Biochemistry and Nutrition has shown that supplementing obese mice with lemon polyphenols extracted from lemon peels prevents body weight gain and improves insulin resistance. Studies in humans are required to confirm these findings.
3 Treatment of kidney stones
Kidney stones are usually treated with potassium citrate. Unfortunately, some patients experience side effects from this medication. In 2008 the Bakirkoy Research and Training Hospital investigated whether lemon juice could be an alternative to potassium citrate. The researchers concluded that lemon juice increases urinary citrate levels and could be an effective treatment for people who suffer from calcium kidney stones.
4 Increase of the biological activity of all organs and body systems
A study from the Medical Institute Reaviz has revealed that 50 ml of fresh lemon juice one hour after ingestion provides an increase of 56.5 procent of the biological activity of all organs and body systems. In particular, the cardiovascular system, the stomach, pancreas, spleen, large intestine, lungs, liver, gallbladder and to a lesser extent the bladder system will be activated. The researchers recommend the use of fresh lemon juice if the function of aforementioned organs and body systems is weak.
5 Protection of the liver and kidneys
A study by the Panjab University of India has shown that hesperidin (citrus bioflavonoid in lemons) provides a protective effect against liver and kidney damage in rats. Unfortunately, no research has been done in humans.
A disadvantage of lemon water is that it can lead to dental erosion. A study from the University of Vale do Itajai in Brazil has revealed that lemon juice causes discoloration of the enamel and loss of dental tissue. The erosive effect is enhanced when lemon juice is consumed with hot water. Researchers at the Medical University of Hanover have concluded that erosion depth increases when acid temperature grows higher. The negative effects of lemon water can be reduced by using a straw and by rinsing the mouth with water. It is recommended not to brush the teeth immediately afterwards. The enamel is still weak and brushing the teeth can damage it.
Although lemon water has several health benefits, one must be careful not to damage the teeth. In my opinion it is wise to drink with a paper straw and to neutralize the acid by rinsing with water.
