Please display caffeine contain next to the menu name

Hello, I am a high school student living in Korea.
Starbucks is a popular brand all over the world, and I also visit Starbucks when I want to have sweet desserts with my friends.
However, when I looked at how much caffeine I had in my coffee, I found that there was 150 mg of caffeine in the tall size of Americano, which I mainly drink.
Of course, Starbucks has a variety of menus, and many of them don't contain much caffeine, but I was surprised to find that there are menus that contain high caffeine.
If you take an appropriate amount of caffeine, of course, it will help you relieve fatigue and have a positive effect. However, excessive caffeine intake can cause insomnia, anxiety, increased heart rate, nausea, excessive stomach acid, and can cause nervousness, muscle cramps, palpitations and insomnia during addiction.
Especially for young people who have not yet fully grown up, caffeine can act as an even more dangerous factor. However, children don't know much about the dangers of caffeine. In fact, there was an incident in which a teenage student of Southcarolina died from caffeine overdose. In order to prevent such incidents from occurring again, influential companies like Starbucks should take the lead in informing teenagers of the side effects of caffeine with caution against the dangers of caffeine.
In order to provide people with information about caffeine content and ensure proper consumption, you have to display caffeine contain next to the menu name
You can also warn consumers about a danger of caffeine consumption by placing a small warning sign next to the menu on app.
This way, consumers will be able to select menus with information based on caffeine content. In addition, changes in responsible companies will reduce the number of cases in which teenagers consume too much caffeine without their knowledge.
