In the scorching summer, a glass of iced beer or drink can make you feel the heat immediately fade away. In fact, this is just a momentary pleasure. What people don't realize is that these icy treats can impair digestive function, lower resistance, and make a person more susceptible to heatstroke.
Dr. Ximu, Vice Chairman of the China Health Expert Committee Committee and a nutritionist, told reporters that the metabolism and transformation of cells require the participation of enzymes. The human body has thousands of enzymes, and almost all life processes, from glandular secretion to the normal functioning of the immune system, require the involvement of enzymes.
Enzymes are most active between 35°C and 40°C, most active at the human body temperature of 37°C, and lose their activity above 60°C. If you consume too many iced foods in the summer, the local temperature of the body drops temporarily. At this time, because the body cannot adapt to such a low temperature all at once, the digestive system is the first to be affected, which in turn affects the normal functioning of all systems in the body. In the hot summer, this can easily lead to heatstroke.
In addition, cold drinks pass through the stomach and intestines much faster than food at room temperature, which can make you thirstier the more you drink. Therefore, iced beer, ice cream, and other cold drinks are actually fireballs in icy clothing. The calories they contain not only cause your weight loss plan to fail, but also make it easier for summer heat to invade. Cold drinks are not a scourge; if consumed in moderation and slowly, they will not cause the aforementioned side effects. Moreover, different people have different tolerances for cold drinks. It is best for the weak and those with cardiovascular diseases to avoid them. Infants and young children should also eat fewer cold drinks due to their underdeveloped gastrointestinal function.
