In the heat of summer, women need more fluids and chilled foods to reduce the risk of dehydration , but also to fully enjoy the season.
Due to increased sweating during the hot months, our body loses sodium and potassium , which we can compensate by eating a few pieces of juicy watermelon .
The delicious and refreshing summer fruit contains about 6% sugar and 92% water - it has the highest water content among the fruits. It is a source of vitamins A, B6 and C, as well as thiamine and magnesium.
The refreshing fruit has a low sugar content , which is approximately 5% of that of an apple. 100 g of watermelon has from 30 to 80 calories, depending on the variety.
The composition of the fruit includes the amino acid citrulline , which has a "cooling" effect on the body, improves the activity of the urinary system and the excretion of harmful substances in the urine.
Watermelon with a reddish-pink flesh is a significant source of lycopene , which gives color to its interior. Clinical studies show that lycopene is associated with the protection of white blood cell DNA, due to its antioxidant function.
The rich content of antioxidants in watermelon is believed to help reduce the risk of cardiovascular disease, osteoporosis, rheumatoid arthritis, asthma and various cancers.
Consumption of watermelon is also beneficial for eyesight , as the fruit is rich in vitamin A and beta-carotene , which improve overall eye health. Studies also show that it helps prevent macular degeneration , a major cause of vision loss in adults.
Watermelon is a good source of potassium , which helps control blood pressure and maintain the body's electrolyte and acid-base balance . Two glasses of watermelon juice contain about 10% of the recommended daily allowance of potassium.
Because it contains vitamin B6 , watermelon is a great food for the brain . The vitamin helps the body create chemicals in the brain that regulate sleep, relieve stress and even create a feeling of high mood and excitement.
According to scientists, when watermelon is consumed, the amino acid citrulline is converted to arginine by certain enzymes. This process is believed to promote heart health .
Arginine is an amino acid useful for the cardiovascular, circulatory and immune systems. A study involving 40 children showed an increase in lymphocytes, which play an important role in the immune system, after oral administration of arginine.
In addition, the amino acid is thought to treat erectile dysfunction . Arginine leads to an increase in nitric oxide, which in turn reduces the tension in the blood vessels. Similarly, Viagra improves erectile function.
However, consuming watermelon does not have the effect of the drug, because it does not have such a concentration of the substance, but it is not to be underestimated the fact that it reduces the tension in the blood vessels without the use of drugs. To achieve this effect it is necessary to eat 6 slices of watermelon.
Another study involving 50 men with impotence showed that participants had a significant improvement in sexual function after taking an arginine supplement.
The amino acid also helps eliminate toxins . Arginine plays an important role in wound healing and in clearing the body of ammonia and other toxic substances.
Excess ammonia in the blood leads to fatigue, kidney and liver disease.
