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

As we all know, tomatoes contain a powerful antioxidant-lycopene, which can effectively prevent ultraviolet rays and other external radiation from damaging skin cells. But in fact, the content of lycopene 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 eyesight. It is worth mentioning that watermelon also contains a unique amino acid-citrulline. It can restore the elasticity of blood vessels. In addition, citrulline can also inhibit the decomposition of collagen, has antioxidant effect, and can moisturize the skin against ultraviolet rays.

Because lycopene and carotene are fat-soluble vitamins, eating watermelon alone will affect its absorption. I suggest you eat it with oil or full-fat dairy products. When eating, you can cut the watermelon into small pieces and add yogurt or salad. Besides, you can drink a bag of milk when you eat watermelon.

Summer heat prevention and relief

A watermelon contains as much as 93% water, which is essentially cold. It is a good product for clearing away heat and relieving summer heat in summer, and it can purge fire and relieve annoyance. When acute fever, thirst, sweating, sore throat, sore mouth and toothache caused by wind and fire, eating watermelon with the most water can immediately improve dry throat and cleft lip.

It can increase urine volume, reduce the content of bile pigment in human body and effectively reduce the incidence of jaundice.

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 to help lower 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 output, thus lowering blood pressure.

Watermelon has a good detoxification function, which meets the needs of people 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 cold. If it is iced, it is recommended not to eat more, especially for people with cold body and stomach upset.

diabetic

Watermelon contains sugar, mainly sucrose, glucose and some fructose. After eating watermelon, people's blood sugar will rise. Normal and healthy people will secrete insulin in time, which can keep blood sugar and urine sugar at a normal level. Different from diabetics, these people will eat too many watermelons in a short time, which will lead to high blood sugar, even acidosis and even life-threatening due to metabolic disorder.

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 this kind of patients eat too much watermelon, they will consume too much water and can't excrete excess water in time, which will lead to excessive water storage in the body and increased blood volume, which will not only aggravate edema, but also easily induce 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 colds and wind-heat colds belong to exterior syndrome in the early stage, and should be treated according to syndrome differentiation. It is believed that the attack will aggravate the condition before the surface is solved. Watermelon has the function of clearing away heat. Eating watermelon at this time will aggravate the cold or prolong the course of disease.

Patients with oral ulcer

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

pregnant woman

Maternal health is weak, 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 can easily lead to abdominal distension, diarrhea, loss of appetite and other diseases, so pregnant women should eat melons in moderation. Besides, don't eat iced watermelons. The chilled watermelon just taken out of the refrigerator is too cold, which is easy to make pregnant women contract 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 watermelon before and after meals will affect the digestion and absorption of food. Eating a lot of watermelon before meals will occupy the volume of the stomach and 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 their food intake.

Watermelon should not be eaten more.

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

Eat less iced watermelons.

Although eating iced watermelon on a hot day has a good effect of relieving summer heat, it is very irritating to the stomach and is easy to harm the spleen and stomach, so we should pay attention to grasping the delicious temperature and quantity. Watermelon is best placed at the bottom 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. Eat slowly. For people with dental caries (tooth decay) and tooth allergies, they will feel sour and painful after catching a cold, and people with poor gastrointestinal function are not suitable for eating iced watermelons.

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