Introduction: With high temperatures, chilled foods are very popular. Eating cold foods in moderation can help cool down and beat the heat, but if you indulge excessively in the icy sensation, it can harm your health.
■ Eating too many ice pops and ice cream affects appetite
Although ice pops and ice cream can relieve heat, quench thirst, and refresh the mind, excessive consumption can damage the gastric mucosa. Frequent cold stimulation can cause the blood vessels of the gastric mucosa to constrict and reduce gastric juice secretion, leading to decreased appetite and indigestion. Over time, this can lead to stomach problems. People with acute or chronic gastrointestinal diseases should especially eat less or none at all.
■ Drinking too many cold drinks can easily cause indigestion
Excessive intake of cold drinks not only causes the blood vessels of the gastric mucosa to constrict and reduces gastric juice secretion, but also accelerates intestinal peristalsis after the intestines are stimulated by cold, affecting the body's absorption of nutrients. This can lead to gastrointestinal symptoms such as indigestion, abdominal pain, and diarrhea. Moreover, after a large amount of cold drink enters the mouth, the pharyngeal mucosa constricts when exposed to cold, reducing its resistance and allowing bacteria lurking in the throat to take advantage, easily causing colds and other illnesses. Ten "Best" for Summer Life
Some people, after intense exercise, immediately consume large amounts of cold drinks, thinking this will "cool them down thoroughly." In fact, this is wrong. Because intense exercise redistributes blood throughout the body, most of it is in the limbs while the gastrointestinal tract has less blood. If it encounters cold stimulation, the blood vessels of the gastric mucosa constrict, further reducing blood flow to the gastrointestinal tract and sharply decreasing gastric juice secretion. This leads to gastrointestinal dysfunction, affecting food digestion. In severe cases, it can even cause vomiting, abdominal pain, and diarrhea.
■ Eating too much iced watermelon damages the spleen and stomach
Some people like to refrigerate watermelon for a while before eating it. In fact, if watermelon is refrigerated for too long, a film forms on the surface of the pulp, and the cold air is absorbed by the pulp. Eating this frozen watermelon can cause the salivary glands, taste nerves on the tongue, and periodontal nerves to become numb due to the cold stimulation. This not only makes it difficult to taste the sweetness of the watermelon but can also damage the spleen and stomach, causing pharyngitis. You should take the watermelon out of the refrigerator and let it sit for a while before eating it. Be cautious of "sweaty chairs" in summer
■ Beer temperature should not be too low
Some people store beer in the refrigerator to drink it fresh and cold, but this is unscientific. Because the temperature of beer should not be below 0°C; if it is at a low temperature for a long time, it will freeze. Frozen beer will appear cloudy, and even after it melts, its taste will be greatly diminished.
In the summer heat, it's easy to feel listless and have a poor appetite. In fact, as long as you arrange your diet reasonably and eat some cold drinks in moderation to keep your body's nutrition balanced, you can get through the summer safely.
