Describe caffeine What Is It?

A naturally occurring substance, caffeine stimulates the central nervous system to increase alertness and ward off drowsiness.
In particular, it is common in cocoa beans, tea leaves, and coffee beans. It is present in the leaves, seeds, and fruits of many different plants.
A lot of goods, such as energy drinks, soft drinks, and some over-the-counter drugs, sometimes include it as an ingredient.
Caffeine is currently the most widely consumed substance worldwide 
An estimated 85% of Americans drink at least one caffeinated beverage every day, consuming 165 mg of caffeine on average. Although most people who consume caffeine do so through coffee, a significant amount of the intake for individuals under the age of 18 comes from carbonated soft beverages like Coke.

For what reason does caffeine exist in soft drinks?

You stay up and energized because caffeine stimulates the central nervous system.
Cola drink manufacturers (like Coca-Cola) used to create their beverages with kola nut extract, which naturally contains caffeine. This meant that caffeine was a naturally occurring ingredient in cola drinks.
Afterward, Coca-Cola added extracts from the coca plant to their beverages. Because none of these natural sources is used anymore, it is only natural that fizzy sodas would include caffeine to replace the kola nut flavor. This is the justification given by soft drink companies.

In 1980, the FDA suggested removing caffeine from soft drinks. In response, manufacturers of soft drinks claimed that caffeine was added for flavoring purposes and was safe for consumption.
Caffeine is found in over 60 different plant species; the most well-known are cocoa beans, kola nuts, and tea leaves. Many popular soft drinks include caffeine, as do a range of pharmaceutical preparations and over-the-counter medications such as analgesics, diet aids, and cold and flu remedies.

Four cups a day or 400 mg of caffeine are generally not problematic for most people. Still, even small amounts of caffeine can trigger anxiety, restlessness, insomnia, and a racing heart if you are sensitive to the stimulant.
Nutritionists and health experts consider it excessive to consume more than 600 mg of caffeine per day or 4–7 cups of coffee. Long-term overindulgence in caffeine (more than four cups of coffee a day) might lead to the following symptoms:

  • Uncertainty
  • Having trouble falling asleep
  • Cuts
  • Bone Loss in Women After Menopause
  • Headaches and irritability
  • lightheadedness with ear-ringing
  • Tremor in the muscles
  • Fatigue and weakness
  • accelerated breathing and heart rates
  • diarrhea, vomiting, nausea, and poor appetite
  • a rise in thirst
  • repeated urination
  • irregular heart rhythm or pace
  • Low blood pressure along with dizziness
  • seizure, confusion, or insanity.

Just two 8-ounce (237-ml) cups of coffee or about five 8-ounce (237-ml) glasses of green tea make up this amount, for estimation purposes.
However, to consume this much, you would have to consume more than six 12-ounce (355-milliliter) cans of Coke or four 12-ounce (355-milliliter) cans of Diet Coke per day.
