Healthy coffee drinking should keep in mind the four elements of coffee drinking basics

With the development of modern science and technology, coffee has gradually entered the families of ordinary Chinese people, and the various beneficial ingredients in coffee are more and more well known. Recent studies have shown that moderate consumption of coffee will not raise cholesterol, but drinking too much coffee can easily lead to gastrointestinal discomfort, so how to drink coffee is the right way?

Coffee

Coffee is a drink made from coffee beans. Due to different processing, it is divided into refined coffee, instant coffee and decaffeinated coffee. Coffee contains small amounts of nutrients. Take refined chopped coffee as an example, every 100 grams contains 0.2 grams of protein, 0.1 grams of fat, 0.4 grams of carbohydrates, 3 milligrams of calcium and 0.1 milligrams of iron. These nutrients are insignificant to the nutritional needs of the human body, and we cannot rely on coffee to provide nutrition. We drink coffee because it is refreshing, which mainly comes from caffeine, which excites the central nervous system, relieves fatigue and improves work efficiency.

1. It takes too long to make coffee.

In order to keep its flavor unchanged, coffee should not be boiled for a long time. Because steam bubbles carry some aromatic substances and gather on the surface of coffee to form foam, and the aroma of coffee depends on the density of the foam. If the coffee continues to boil after it is boiled, the foam will be destroyed and the aroma will run away with the steam. And coffee should also be drunk immediately after it is cooked, otherwise its foam will be destroyed if it is cooled.

two。 Don't drink coffee with too much concentration.

Some people work and study hard in order to buy time, often with the help of high concentrations of coffee to stimulate the brain and nerves, in order to refresh and drive away difficulties. In fact, this will do more harm than good. According to research, after drinking a high concentration of coffee, adrenaline increases sharply in the body, resulting in a rapid heartbeat, a significant increase in blood pressure, and abnormal phenomena such as nervousness, restlessness, tinnitus and involuntary trembling of the limbs, which will affect health in the long run. If it is to take an examination of students or actors, athletes, before entering the examination room, competition field, drink high concentration of coffee, it is likely to be abnormal because of excessive excitement of the body; if there are diseases such as arrhythmia and tachycardia, drinking high concentration of coffee can aggravate the illness; people with coronary heart disease and hypertension can induce angina pectoris and cerebrovascular accidents, so drinking coffee concentration is too high.

3. Don't put too much sugar in your coffee.

When drinking coffee, a little sugar can increase the taste of the coffee. However, if you put too much sugar, it will make people lethargic and even make people feel very tired. According to analysis, there are two main reasons for the above situation: first, after coffee enters the human body, it will consume some minerals in the body, and these minerals are indispensable in the process of converting carbohydrates into glucose. Second, when drinking coffee, adding too much sugar will reflexively stimulate islet cells in the pancreas and secrete a large amount of insulin, while excessive insulin can reduce the content of glucose in the blood. Once the blood sugar is too low, there will be palpitations, dizziness, weakness, drowsiness and other hypoglycemic symptoms. In addition, when drinking coffee, it is not appropriate to eat too much cake, candy and other high-sugar food, otherwise it will also produce the above phenomenon.

4. Choose the right time to drink coffee

Drinking coffee is best after breakfast and lunch, because it can promote gastrointestinal peristalsis and help digestion; it can break down high-energy, high-fat foods that can be eaten, and will not cause irritation to the stomach like drinking coffee on an empty stomach. But it's best not to drink coffee after dinner, because it will affect your sleep.
