Drinking coffee at the wrong time can greatly reduce the absorption of nutrients

　　Coffee is an essential drink for many people every day. It can refresh, improve memory, prevent depression and so on. But, you know what? The timing of drinking coffee is also very important. If you do not pay attention, it may affect your health and nutrient absorption.
　　First, don’t drink coffee immediately before or after meals. Because the caffeine and phenolic substances contained in coffee will affect the secretion of gastric acid and digestive function, leading to stomach discomfort, loss of appetite, and nutrient loss. In particular, minerals such as iron, calcium, and magnesium will be combined into insoluble compounds by substances in coffee, thereby reducing their absorption rate. Therefore, drink coffee at least one hour before or after meals, preferably two hours before or after meals, so that you can enjoy the aroma and taste of coffee while avoiding nutritional loss.
　　Second, don’t drink coffee before going to bed. Because caffeine stimulates the nervous system, prolongs waking time, and affects the quality and depth of sleep. Sleep is an important process for the body to repair and recover. Insufficient or poor sleep will affect the body’s immunity, metabolism, endocrine, etc. Therefore, it is best to avoid drinking coffee within 6 hours before going to bed, so that you can have a restful sleep.
　　Finally, don’t drink too much coffee. Although coffee has many benefits, but too much is too much. Everyone’s tolerance and reaction to caffeine is different, and generally speaking, it is safe to consume less than 300 mg of caffeine per day. In other words, drinking 3-4 cups of black coffee or 2-3 cups of latte a day is the peak. If you drink too much coffee, you may experience side effects such as heart palpitations, anxiety, insomnia, headaches, and even cardiovascular diseases and osteoporosis.
　　In short, you should pay attention to the timing and measurement of drinking coffee in order to give full play to its advantages and avoid its disadvantages. Drinking coffee should also be adjusted according to your physical condition and needs, and don’t blindly follow trends or be superstitious. Only in this way can coffee become a beautiful scenery in your life.
