Let Lao Huangli introduce you to the precautions for eating watermelon in the dog days.

Watermelon has the functions of clearing away heat, quenching thirst and diuresis. Suitable for summer heat, polydipsia, short and red urine, edema and sores on the mouth and tongue. On a hot day, many people like to eat a cold and sweet iced watermelon.

It is not suitable for eating at the beginning of a cold.

Chinese medicine divides colds into wind-cold and wind-heat. At the beginning of a cold, eating too many watermelons is likely to aggravate the cold and illness without knowing what type you belong to. If it has been confirmed that it is a wind-heat cold, accompanied by internal heat symptoms such as high fever and thirst, you can eat a small amount of watermelon to help clear away heat and detoxify.

People with oral ulcers are not suitable for eating.

From the point of view of traditional Chinese medicine, the main causes of oral ulcer are internal heat due to yin deficiency, disturbance of deficiency fire and burning pulse. Watermelon has diuretic effect. If people with oral ulcer eat more watermelon, the water normally needed in the body will be discharged through the diuretic effect of watermelon, which will aggravate the state of insufficient vaginal fluid. Yin deficiency will increase internal heat and aggravate oral ulcer.

People with renal insufficiency should not eat it.

People with renal insufficiency should not eat it. Eating a lot of watermelon in a short time is easy to increase the water in the body, which exceeds the physiological endurance. In patients with renal insufficiency, the ability of kidney to regulate water is reduced, and too much water entering the body can not be regulated and excreted, resulting in a sharp increase in blood volume and easy death due to acute heart failure.

Diabetic patients should not eat.

People with diabetes should eat less. The sugar content of watermelon is about 5%. If diabetics eat too much watermelon, their blood sugar will rise, urine sugar will increase, and in severe cases, there will be a coma reaction of ketoacidosis. Eat 25-50g watermelon at a time, which is suitable for diabetics.

Pregnant women should not eat.

Due to the physiological changes of endocrine in pregnant women, the insulin in the body is relatively insufficient, which reduces the stabilizing effect on blood sugar, leads to high sugar concentration in the blood, and leads to gestational diabetes, which is an important cause of miscarriage and premature delivery in pregnant women. Therefore, pregnant women should not eat too much watermelon.

Maternal women should not eat.

Maternal health is relatively weak. From the perspective of traditional Chinese medicine, watermelon is cold, and eating too much will lead to excessive cold and damage the spleen and stomach.

Not suitable for menstruating girls.

During the menstrual period, girls' physique is also weak and their immunity is reduced. Watermelon, a cool thing, is best not to eat.

Not suitable for the elderly.

Because the elderly are older, most people's spleen and stomach functions and heart and kidney functions will be weakened. Eating too much watermelon in summer will damage the spleen and stomach.

Watermelons can't be eaten if they are in bloom for too long.

The temperature is high in midsummer, and bacteria are easy to reproduce. Watermelon is easy to produce a large number of germs if it is opened for too long, which may lead to gastrointestinal discomfort. Therefore, when eating watermelon, we should pay attention to choosing ripe fresh watermelon, and it is best to eat it at that time.

Not suitable for eating before and after meals.

A large amount of water in watermelon will dilute the digestive juice in the stomach, and eating watermelon before and after meals will affect the digestion and absorption of food, while eating watermelon in large quantities 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.

Ice watermelon is not edible.

Eat less iced watermelons. It can be stored at the bottom of the refrigerator (the temperature is 8℃- 10℃). Take it out and leave it at room temperature for a while before eating. At this time, the taste is the best. Don't eat more than two pieces at a time, eat slowly.

Watermelon should not be eaten after 2 1: 00, otherwise it will easily become a "watermelon belly". If you feel that a little watermelon can't satisfy your stomach, it is recommended to peel off the hard skin on the surface, add sugar, salt and various condiments according to your own taste, and make cold watermelon skin, which is refreshing and slimming.
