People who drink coffee regularly should pay attention to calcium supplementation at the same time. Who is not suitable for drinking coffee?

The caffeine in coffee can speed up the body's metabolism, quickly excrete waste keratin from the body, and effectively lighten dark circles. Drinking coffee regularly can keep the skin vibrant, slow down the oxidation of skin cells, and fight skin aging. Although coffee has so many advantages, you should also pay attention to calcium supplementation.

Drinking coffee regularly should also take calcium supplements

The Chinese people's daily food structure lacks sufficient calcium intake, and they are lazy to exercise, so people who like to drink coffee should pay attention to calcium supplementation. For women who have entered menopause, drinking coffee will also cause calcium loss due to the lack of estrogen.

Adults who drink coffee regularly can supplement 100 mg of calcium every day, or drink at least a cup of milk a day to supplement calcium. Because the caffeine content in a cup of coffee is about 50 mg, for Chinese people who already have calcium deficiency, they should pay attention to supplementing calcium when drinking coffee regularly.

Drinking moderate amounts of coffee can prevent gallstones

Coffee is popular among some citizens because it can refresh the mind. The caffeine in coffee stimulates the central nervous system, making the mind clearer, thinking more fully and concentrating, thus improving work efficiency. Therefore, when working overtime or staying up late, some citizens often take coffee as a must-have drink. Experiments have shown that absorbing 300 mg (about 3 cups of brewed coffee) of coffee a day will have a good effect on a person's mood.

In addition, some studies have shown that caffeinated coffee can stimulate gallbladder contraction and reduce the cholesterol in bile that is prone to form gallstones. Men who drink two to three cups of coffee a day have a 40% lower chance of getting gallstones.

Avoid drinking coffee on an empty stomach

Doctors remind the public not to drink coffee on an empty stomach, because coffee can stimulate gastric acid secretion, especially for people with gastric ulcers. Coffee is a beverage that should be consumed in moderation according to individual conditions. In general, nutrition emphasizes a balanced diet and less spicy food.

In addition, it is worth noting that patients with hypertension should avoid drinking caffeinated beverages when they are under great work pressure, because the caffeine in coffee may cause blood pressure to rise, and if it is combined with emotional tension, it will have a dangerous multiplying effect.

According to reports, studies have shown that after drinking a cup of coffee, blood pressure can remain elevated for up to 12 hours.

Who is not suitable for drinking coffee?

1. Patients with arrhythmia should not drink strong tea or coffee

Tea contains theophylline and coffee contains caffeine, both of which can excite the central nervous system. After drinking strong tea and coffee, the central nervous system is excited, and the sympathetic nerves that control the heart are also excited, which speeds up the heartbeat and makes people irritable. It is easy to cause excessive myocardial fatigue, heart failure, drowsiness, shortness of breath, purple lips and other symptoms, or even life-threatening. Therefore, patients with arrhythmia should not drink strong tea and coffee.

2. Patients with peptic ulcer should not drink strong tea and coffee

Tea can clear the head, relieve thirst, boost spirits, resolve phlegm, help digestion, promote urination, and detoxify. It is a refreshing drink that many people like to drink. However, patients with ulcers should not drink tea, especially strong tea. This is because some chemical components in tea, such as caffeine, theophylline, and theobromine, can strongly stimulate gastric acid secretion, and the intensity of the stimulation is proportional to the concentration of tea. The higher the concentration of tea, the more gastric acid secretion is stimulated, the more severe the stimulation to the ulcer wound, and the more the ulcer develops. Most of the drugs currently used to treat ulcers work by inhibiting gastric acid secretion. It can be seen that drinking strong tea often is not conducive to the healing of ulcers. For the same reason, coffee is not suitable for drinking.

3. Patients with viral myocarditis should not drink strong tea or coffee

The large amount of theophylline in strong tea and the caffeine in coffee can excite the central nervous system and myocardium, making people excited and their heartbeat faster. The myocardial oxygen consumption increases, causing myocardial hypoxia and aggravating myocardial damage, thus aggravating myocarditis. It may even cause severe arrhythmia, palpitation, shortness of breath, chest tightness, dizziness, nausea, breathing difficulties, or even syncope and convulsions. Therefore, patients with viral myocarditis should not drink strong tea and coffee.

In addition, patients with viral myocarditis should not eat spicy foods such as peppers, raw onions, raw garlic, or high-fat greasy foods. They should eat a light, easily digestible diet rich in protein and vitamins. They should also quit smoking and drinking.
