Why does drinking coffee make you dizzy?

Drinking coffee makes you dizzy. It may be because coffee contains caffeine, which leads to excessive excitement of brain nerves. Excitement becomes inhibition, which can cause dizziness. Then there are some substances in coffee that can lower blood sugar. Drinking a lot of coffee will reduce the blood sugar level in the body, causing hypoglycemia and dizziness. Drinking a lot of coffee, especially on an empty stomach, will cause systemic telangiectasia, leading to insufficient blood supply to the brain, cerebral ischemia and hypoxia, and dizziness.

No matter what kind of coffee, freshness is an important factor affecting the quality. When buying, grab one or two coffee beans and chew them in your mouth. If it is crisp and intact, it means that the coffee beans are not wet, and the coffee beans with fragrant lips and teeth are top grade, but it is best to pinch them by hand to see if they feel solid. Never buy empty coffee.

Freshly fried coffee beans are not suitable for immediate drinking. Generally speaking, the best drinking period of coffee is one week after frying, when the coffee is freshest and has the best aroma and taste.

In addition, the taste of coffee beans is another consideration. Experts choose coffee beans, but not necessarily according to the size of the particles. Coffee beans may vary in size in appearance. For example, it is normal for beans in Ethiopia to have different characteristics. Second, color. It is normal that dried beans will have different colors whether they are raw or cooked. Don't read my humble opinion in books or materials one-sidedly, generalize all coffee beans.

Relatively speaking, medium-deep roasted coffee beans are easier to produce oil than lightly roasted coffee beans, while lightly roasted coffee beans have no oil or little oil. In a word, when buying coffee, we should pay attention to its freshness, aroma and bad taste.
