What happens to your body when you drink watermelon juice

Watermelon juice is a nutritious and moisturizing drink filled with plugs, magnesium and potassium, which can help fluid maintenance and exercise performance.

1. It provides hydration

Watermelon helps you improve your water consumption: more than 90% of the fruit is water. Whether you eat watermelon or drunk watermelon juice stimulates your hydration.

“A cup of diced watermelon contains 139 milliliters of water,” Alexandra Rosenstock, CDN, CDN, Telwell told Telwelrian.

This is one of the reasons why it can be refreshing after spending time outside with a hot day.

“Given its water content, the watermelon can help reconstruct the liquids if you feel slightly dehydrated after spending time in the sun, especially if you are consumed with a salty snack,” said Rosenstock.

2. It offers electrolytes

Watermelon juice is an excellent source of electrolytes, including magnesium and potassium.

“The electrolytes are lost in sweat, therefore during the exercise or sweating in the heat, the replenishment of electrolytes is useful,” Julia Zumbano, RDN, LD, dietitist at the Cleveland Clinic Institute of Digestive Institute.

The electrolytes are essential and play a role in many bodily processes. Magnesium helps your muscles and your brain to operate normallyAnd potassium, which is in all body tissue, helps your cells to operate normally.

3. It stimulates essential nutrients

Many nutrients that your body needs every day – and which are a balanced and well -balanced diet – can be found in watermelon juice.

“Watermelon juice contains vitamin A, vitamin C, lutein, folate”, and even more, “said Rosenstock.

4. This can help lower your blood pressure

The L-Citrulline, an amino acid, is also in watermelon juice.

“Watermelon contains Citrulline, which has proven to help control blood pressure,” said Zumpano. L-Citrulline has also been linked to increased bioavailability of nitric oxide, suggests research.

When the bioavailability of nitric oxide is decreased, you may be more at risk of high blood pressure, atherosclerosis, insulin resistance, type 2 diabetes and cardiovascular disease.

5. It may have other advantages for heart health

Another amino acid called L-Arginine can also be found in watermelon juice.

“L-arginine has been associated with certain health benefits, including improving blood circulation and perhaps blood pressure,” said Rosenstock.

Research has shown that L-arginine can be beneficial for people with high blood pressure, high cholesterol, heart disease, insulin resistance and diabetes.

Watermelon juice also contains lycopene and beta-carotene, which are both antioxidants, just like vitamin C.

Antioxidants promote cardiovascular health and can prevent or slow down certain types of cell damage.

“It has been shown that Lycopene helps improve blood lipids and blood pressure,” added Zumpano.

6. This can help weight loss

Eating watermelon has been linked to higher speed quality (in adults and children)Watermelon juice can be useful for painful musclesAnd research suggests that watermelon could also help some people manage their weight.

Another advantage of the watermelon is that you can consume everything: after sipping the watermelon juice and ate the fruit, the bark can be cooked, sautéed or marinatedAnd the seeds are also edible.
