Coffee taboo, you must pay attention to it!

First, avoid coffee with smoking: studies by medical experts have shown that caffeine, under the action of mutagenic substances such as nicotine in cigarettes, can easily mutate some tissues in the body, and even lead to the production of cancer cells. Therefore, when drinking coffee, we must abandon the bad habit of smoking at the same time.

Second, avoid putting too much sugar: adding too much sugar when drinking coffee will reflexively stimulate the islet cells in the pancreas to 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 symptoms.

Third, avoid too high concentration: according to research, after drinking high concentration of coffee, the secretion in the body increases sharply, so that the heartbeat rate speeds up, the blood pressure increases obviously, and it is prone to abnormal phenomena such as nervousness, irritability, tinnitus and involuntary trembling of the limbs, which is harmful to health in the long run. If suffering from arrhythmia, tachycardia, neurosis and other diseases, drinking high concentration of coffee will promote or aggravate the original condition. People with coronary heart disease and high blood pressure, such as excessive drinking of espresso, even have the risk of angina pectoris and cerebrovascular accidents. Generally speaking, the concentration of caffeine in each cup of coffee should not exceed 100 mg, and the amount of coffee consumed should not exceed 3 cups a day.
