Let’s start with the conclusion: Iced Americano can eliminate edema.
Among them, the effect of reducing edema is "caffeine", that is, as long as it is not decaffeinated coffee. Whether it is an ice American or a hot American, or a latte, it can have the effect of eliminating edema.
Caffeine, also known as caffeine and caffeine, mainly comes from coffee beans and tea leaves. It has a selective excitatory effect on the cerebral cortex, which can speed up blood vessel movement, speed up breathing and increase blood pressure. It can reach the whole body and has a certain diuretic effect, so it can play a role in eliminating edema and expel the water retained in the body.
For normal people, caffeine is very safe, and it was included in the GRAS list (generally safe ingredient) by the US FDA as early as 1958. If you drink too much water at night, or eat too salty, and edema the next day, you might as well drink a cup of coffee in the morning, and it will disappear quickly!
One of the reasons why celebrities like American coffee is probably that American coffee is pure black coffee, with no added sugar, no creamer and other ingredients. Other coffees with added sugar & creamer not only add a lot of extra calories, but are also very unhealthy.
If you don't like the taste of black coffee, you can choose latte. You can mix some milk in coffee to make homemade latte. This not only improves the taste, but also consumes a certain amount of dairy products, which is still very healthy.
There are many advantages of coffee, in addition to eliminating edema, it can also:
Accelerates fat burning: Drinking it 40 minutes before exercise can improve exercise endurance and persist for a longer time, thereby burning more fat.
Relieve constipation: Caffeine can stimulate intestinal peristalsis and help us expel the remaining poop.
Suppressing appetite: Drinking it more often can make you want to eat more if you have less appetite.
However, some people experience symptoms such as nausea and increased heart rate after drinking coffee, which is caffeine intolerance.
If you are caffeine intolerant, you can try drinking a small amount of time to reduce your caffeine intake. If you start to have a fast heart rate, frequent urination, and insomnia after just one sip, then you might as well give up coffee. After all, the role of coffee is just icing on the cake, not a necessity.

When do you drink coffee?
It is recommended to be in the morning or in the morning, which can refresh the mind and start the work of the day.
It is not recommended to drink after 4pm. Caffeine has a stimulating effect on nerves. If you drink too late, you may not be able to sleep at night.
In addition, caffeine can hinder the absorption of some nutrients, such as calcium and iron. If you are usually deficient in calcium and iron, try to avoid meals when drinking coffee.

How much coffee can you drink in a day?
The current general theory is that it is safe for normal people to consume 400 mg of caffeine per day, and the total daily intake of caffeine during pregnancy and breastfeeding should be less than 200 mg.
The content of caffeine in different coffees is different. Let me give you a data reference from the Mayo Clinic.
It is the highest in freshly brewed pour-over coffee, as high as 95-165mg in a cup, because it uses a lot of coffee; while a 30ml cup of espresso has 47-64mg; instant coffee has 63mg; latte or mocha have 63-126mg.
For our daily life, this instant black coffee is more convenient, and it can also be made into a latte with milk, and the caffeine is not much different.
In general, if you like to drink coffee, 3-5 cups a day is OK.
But does anyone really drink that much? One cup a day is enough for me.
