Eat a piece of watermelon on a hot day, and the feeling of sweetness and refreshment runs through the whole body in an instant. This experience does not mention how happy you are. But do you really understand the big questions that watermelon is tangled?
Eating watermelon is easy to gain weight or help to lose weight? The data shows that the calorie per 100 grams of watermelon is 26 kcal, which is not high in fruits, lower than strawberries, peaches, apricots, grapes, pears, apples, etc. It should be noted that this does not mean that watermelon is more conducive to weight loss than apples, because the unit heat of watermelon is low, but it is easy to eat more if you are not careful. The heat of 1/4 watermelon (about 700 grams) is about the same as the calorie of a small bowl of rice. If you eat 1/4 or even half of watermelon on the basis of normal eating every day, it will definitely make you fat. The New Dietary Guidelines recommend that adults consume between 200 and 350 grams of fruit per day. Eat watermelons in accordance with this recommended amount.
Can diabetics eat watermelon? The average sugar content of watermelon is 5.8%, which is less than apples, pears, melons, grapes and other fruits. However, the glycemic index of watermelon is not low, at 72, significantly higher than other common fruits, such as apples and pears with a glycemic index of 36 and peaches of 28. This means that if diabetics eat too much watermelon in a short period of time, it is easy to cause blood sugar to rise. Therefore, this group of people should limit their consumption when eating watermelon, and only eat 100~150 grams per day.
Why is the watermelon after chilling sweeter? The sugar in watermelon is mainly fructose, and the sweetness of fructose has a great relationship with temperature. The lower the temperature is below 40 °C, the higher the fructose is, the highest is 1.73 times of sucrose. The specific reason is that fructose has two molecular configurations: α-type and β-type. The fructose of α-fructose is only 33% of β-fructose. At low temperature, the balance of the two moves toward β-fructose, so the sweetness increases.
Is seedless watermelon used because of birth control pills? Seedless watermelons are hybridized. The principle is to convert diploid plants that can normally produce seeds into triploid plants by hybridization, hinder the normal development of seeds, and give some stimulation to make the fruits themselves enough. Developed plant hormones that promote fruit formation. Therefore, seedless fruits and contraceptives have nothing to do with it.
Can you eat watermelon overnight? The watermelon that has not been eaten is really not suitable for a long time. If it is properly preserved, the overnight watermelon can also be safely eaten. Cut watermelons are usually placed for up to 4 hours at room temperature, and it is safe to refrigerate in time.
