A cup of coffee is a must every day? 5 things you need to know as a coffee lover

Coffee is the favorite condiment for office workers. Drinking a cup before work or when you feel tired due to stress is simply a holy product. Compared with drinks with extremely high sugar content, black coffee is more beneficial to the human body, but everything has two sides, both good and bad. If you want to use coffee to relax your body and mind, you must know the following 5 things.

1. Coffee can reduce health problems caused by stress

For office workers who sit for long periods of time, drinking a moderate amount of coffee every day is definitely beneficial to their health. The reason is that the caffeine and polyphenols in coffee can increase the concentration of nitric oxide compounds in the body, stimulate blood vessel contraction and expansion, keep blood vessels elastic, prevent thrombosis, and maintain the health of the cardiovascular and cerebrovascular system.

2. Coffee has a fat-reducing effect

Many studies have shown that caffeine can increase the metabolic rate by 3% to 11%. For overweight people, drinking coffee can increase fat burning by 10%, while for thinner people, it can be as high as 29%. Coffee can increase fat decomposition in the body, reduce glycogen consumption, and also reduce energy and fat intake. Drinking it one hour before exercise can promote strength, endurance and fat decomposition during exercise. This is because after the caffeine in coffee is absorbed into the blood by the gastric mucosa, the fatty acid concentration in the blood increases rapidly, and the free fat that is difficult to metabolize in the body will be consumed.

3. It is recommended to drink coffee in the morning

The main function of caffeine is to accelerate lymphatic metabolism, stimulate the central nervous system, and fight sleepiness. If you have poor sleep quality or fall asleep very early, it is recommended to drink coffee in the morning to avoid affecting your sleep quality. Of course, if you can't resist the rich and fragrant coffee in the afternoon, you can choose some low-caffeine coffee drinks as a change.

4. Drinking black coffee on an empty stomach hurts your stomach and makes you fat

Coffee is rich in sugar and energy. Drinking coffee on an empty stomach not only hurts the stomach but also makes you fat. Coffee stimulates the secretion of gastric acid. Even if you don't drink it on an empty stomach, it will irritate the stomach. No doctor or nutritionist recommends drinking coffee on an empty stomach. The reason is that the gastric mucosa absorbs caffeine very quickly when you are on an empty stomach. As high concentrations of caffeine enter the blood, the heart and nervous system will be stimulated, resulting in a series of reactions such as dizziness, palpitations, chest tightness, and shortness of breath. It is easy to cause stomach damage, which affects digestion and absorption. In severe cases, it can even lead to gastric ulcers.

5. Drinking black coffee in moderation is the healthiest

Even though drinking coffee has many benefits, you should never drink too much. Generally speaking, a person should not consume more than 300 mg of caffeine a day. This can not only prevent health and skin problems caused by excessive caffeine intake, but also replenish sufficient antioxidant polyphenols to fight against free radicals that invade the body and skin.
