Have you ever heard such a saying? Add fresh milk to dilute or neutralize the coffee to enjoy the mellow flavor of the coffee and avoid excessive caffeine intake. Or from a health point of view, some people say that long-term drinking coffee will be "lack of calcium", so adding fresh milk and tasting coffee can also "supplement calcium"?

In response to this view, well-known coffee roasters said that the amount of coffee in a cup of espresso is fixed, if an appropriate proportion of boiled water is added to become an American coffee (Americano), commonly known as black coffee, the flavor remains the same but the mellow taste will be diluted; if the appropriate proportion of milk is added, it will become the most popular latte on the market (Caf é Latte). Fresh milk enhances the aroma of the coffee and makes it more mellow and palatable. However, regardless of the addition of water or fresh milk, the volume concentration of caffeine is diluted, but the amount of caffeine remains the same, so the idea of diluting caffeine is not valid.

As for the milk coffee with fresh milk in the coffee, can it "make up for the lost calcium"? According to research, long-term consumption of coffee can increase the risk of osteoporosis, while one cup of milk can make up for the calcium lost by eight cups of coffee. Caffeine increases the excretion of calcium in the urine, so the more coffee you eat, the more calcium you lose, according to a study. However, the effect of coffee on the absorption of nutrients is not limited to calcium. A cup of coffee after a meal is likely to reduce the absorption of certain nutrients, including calcium and iron. Therefore, it seems impossible to drink lattes to make up for the calcium loss caused by caffeine.

Caffeine's disadvantages to the human body can not be ignored, but it also has a lot of contribution to health. For example, increase metabolism, stimulate the central nervous system and brain cells, boost spirit and improve work efficiency; a small amount of caffeine can also help speed up blood circulation, but excessive intake can cause palpitations or arrhythmias. Experts warn that a cup of espresso (including espresso, cappuccino and latte) contains about 80 milligrams of caffeine and the maximum daily intake of caffeine is 300 milligrams. The concentration of caffeine is related to the variety of coffee beans, the way they are roasted and the way they are brewed. In principle, the heavier the roasted beans and the shorter the brewing time, the lower the caffeine content.
