Rich in skin care ingredients, it can prevent ultraviolet rays and age.

As we all know, tomatoes contain a powerful antioxidant, lycopene, which can effectively prevent the damage to skin cells caused by various external radiation such as ultraviolet rays. But in fact, the lycopene content in watermelon is 1.4 times that of tomato, which is little known. In addition, watermelon also contains carotene, which is a nutrient element rich in carrots and some yellow-green vegetables. It can be converted into vitamin A in human body, which can resist skin aging, prevent cancer and protect people's vision. It is worth mentioning that watermelon also contains a unique amino acid-citrulline. It has the function of restoring blood vessel elasticity. In addition, citrulline can also inhibit the decomposition of collagen, has antioxidant effect, and can moisturize the skin against ultraviolet rays.

Since lycopene and carotene are both fat-soluble vitamins, eating watermelon alone will affect their absorption. It is recommended that you eat it with oil or full-fat dairy products. When eating, you can cut watermelon into small pieces and add yogurt or salad. Besides, you can also drink a bag of milk when eating watermelon.

Preventing heat and relieving summer heat

A watermelon contains as much as 93% water, which is cold in nature. It is a good product for clearing heat and relieving summer heat in summer, and can purge fire and remove irritability. When acute fever, thirst and excessive sweating, sore throat, sores on the mouth and tongue, toothache caused by wind and fire occur, eating watermelon with the most moisture can immediately improve dry throat and cleft lip.

Watermelon contains citrulline and arginine, which is beneficial to the elimination of kidney inflammation. The protease contained in watermelon can transform insoluble protein into soluble protein, which has a certain curative effect on patients with liver ascites, nephritis and cystitis. It can increase urine output, reduce the content of human bile pigment, and effectively reduce the incidence of jaundice.

reduce blood press

Watermelon itself is not a medicine, only the extract in watermelon can effectively lower blood pressure, and it cannot be lowered by eating habits alone. They can be used as AIDS for lowering blood pressure. Watermelon has the effect of lowering blood pressure because of its high water content, and blood pressure is directly related to sodium. Diuretion is beneficial to sodium excretion, reducing blood volume and cardiac blood output, thus lowering blood pressure.

expel toxin

Watermelon has a good detoxification function, which meets the needs of people's bodies to clean up garbage in summer.

Taboos for eating watermelon

Watermelon is a cool fruit. In hot summer, eating chilled watermelon plays a very good role in relieving summer heat, both in taste and after watermelon enters the body. Note: Watermelon is originally cool. If it is chilled, it is recommended not to eat more, especially for people with cold body and gastrointestinal discomfort.

Diabetic person

Watermelon contains sugar, mainly sucrose, glucose and some fructose. After eating watermelon, people's blood sugar will increase. Normal and healthy people will secrete insulin in time, which can keep blood sugar and urine sugar at normal levels. Unlike diabetics, such people will eat too many watermelons in a short time, which will lead to an increase in blood sugar, and even lead to acidosis and even life-threatening due to metabolic disorders.

Renal insufficiency

In patients with renal insufficiency, the function of expelling water from the body is greatly reduced, so edema of lower limbs or whole body often occurs. If such patients eat too much watermelon, they will consume too much water and can't discharge the excess water in time, resulting in excessive water storage in the body and increased blood volume, which not only aggravates edema, but also easily induces acute heart failure. Therefore, patients with renal insufficiency should eat less or not eat watermelon.

Early stage of cold

Traditional Chinese medicine believes that both wind-cold and wind-heat colds belong to exterior syndrome at the initial stage, and divergent treatment should be adopted to solve the disease from the exterior. It is believed that attacking before the surface is solved will aggravate the condition. Watermelon has the function of clearing away heat, so eating watermelon at this time will aggravate the cold or prolong the course of the disease.

Patients with oral ulcer

In traditional Chinese medicine, oral ulcer is considered to be caused by internal heat due to yin deficiency and disturbance of virtual fire. Because watermelon has diuretic effect. If people with oral ulcer eat more watermelons, the water needed for the recovery of oral ulcer will be discharged too much, which will aggravate yin deficiency and internal heat, and make the course of disease stretch and difficult to heal.

pregnant woman

The maternal constitution is relatively weak, and Chinese medicine believes that eating more watermelon will be too cold and damage the spleen and stomach. Watermelon is cold, and eating too much is easy to hurt the spleen and stomach. Eating too much is easy to cause abdominal distension, diarrhea, loss of appetite and other diseases, so pregnant women should eat melons in moderation. In addition, don't eat iced watermelons. The temperature of iced watermelons just taken out of the refrigerator is too low, which will easily cause contractions for pregnant women and increase the risk of miscarriage.

Not suitable for eating before and after meals.

Because a lot of water in watermelon will dilute the digestive juice in the stomach, eating it before and after meals will affect the digestion and absorption of food, and eating a lot of watermelon before meals will occupy the volume of the stomach, which will greatly reduce the intake of various nutrients during meals, especially for children, pregnant women and lactating mothers. For people who want to lose weight by dieting, eating watermelon before meals is a good way to reduce food intake.

Watermelon should not be eaten too much.

Because watermelon belongs to "cold food", anyone who eats too much will hurt the spleen and stomach, leading to poor appetite, indigestion and decreased gastrointestinal resistance, causing bloating and diarrhea.

Eat less iced watermelon.

Although eating iced watermelon has a good effect of relieving summer heat on a hot day, it is very irritating to the stomach and easy to cause damage to the spleen and stomach, so we should pay attention to grasping the delicious temperature and quantity. It's best to put watermelons on the lowest floor of the refrigerator, where the temperature is about 8- 10, and the temperature is also the best. Don't eat more than 500 grams at a time, and eat slowly. For people with dental caries (tooth decay) and tooth allergies who will feel acid and pain after cold, and those with poor gastrointestinal function, it is not suitable to eat iced watermelon.

Summary: Now is a good time to eat watermelon. Although watermelon is detoxifying and beautifying, it is a fruit with high sugar content, which is easy to be converted into fat. People who want to lose weight should eat less!
