Common mistakes in drinking coffee
Mistake 1: Drink coffee on an empty stomach in the morning.
Coffee contains more caffeine, which can stimulate gastric acid secretion and increase gastric acid concentration. At this point, after a night's rest, my stomach is empty. Hyperacidity can easily damage the gastric mucosa, causing stomach pain, heartburn and even nausea. In addition, drinking a lot of espresso on an empty stomach may also cause discomfort such as rapid heartbeat, chest tightness and palpitation. Moreover, coffee will accelerate the energy consumption of the body, and drinking it on an empty stomach in the morning is likely to lead to hypoglycemia.
Mistake 2: Always drink instant coffee.
Instant coffee is a powder made by extracting effective components from roasted coffee beans and drying them. Usually made into a three-in-one coffee drink, it tastes sweet and delicious, but this sweetness is brought by adding a lot of white sugar, non-dairy creamer and edible essence. If we drink three cups of instant coffee every day, the energy intake will reach more than110 of the energy we need every day. In addition, the main components of non-dairy creamer are glucose syrup and hydrogenated vegetable oil, which contains trans fatty acids harmful to health and should be avoided to be eaten frequently.
Mistake 3: Drink freshly ground coffee and add a lot of sugar.
Usually, adding two bags of 5 grams of sugar to coffee will make you feel moderately sweet, but drinking this cup of coffee will consume an extra 10 grams of sugar. In view of the fact that eating too much sugar may lead to overweight, obesity and dental caries, the World Health Organization (WHO) and the Dietary Guidelines for China Residents (version 20 16) suggest that the daily intake of added sugar should not exceed 50 grams, but should be controlled below 25 grams. It is suggested not to add sugar or less sugar when drinking freshly ground coffee, learn to enjoy the fragrance of pure coffee, or add some milk to enhance the fragrance.
Mistake 4: Drink a lot of coffee when staying up late.
Caffeine in coffee does have a refreshing effect, but drinking it in large quantities will accelerate the metabolism in the body and accelerate the consumption of B vitamins. People who lack B vitamins are more likely to feel tired, so they will want to drink more coffee, which will form a vicious circle in the long run. In addition, studies have shown that drinking a lot of coffee before going to bed will make the body's biological clock go backwards and become a night owl who can't sleep at night and wake up in the morning. In addition, caffeine has diuretic effect. After drinking coffee, you will go to the toilet frequently, which will not only interrupt your work, but also cause water shortage, which will also cause fatigue and drowsiness.
