What is Caffeine?  What are its benefits?​

Answer:

Caffeine is a drug that stimulates (increases the activity of) your brain and nervous system. Caffeine is found in many drinks such as coffee, tea, soft drinks and energy drinks. Chocolate also contains caffeine. Energy drinks often have more caffeine and sugar than soft drinks.

The benefits of caffeine are:

• Caffeine may boost weight loss or prevent weight gain
• A 75-mg serving of caffeine can increase attention and alertness, and a 160 to 600-mg dose may improve mental alertness, speed reasoning, and memory.
• Caffeine can improve physical performance during endurance exercise.
• Caffeine affects adenosine receptors in the brain. Coffee also contains polyphenol antioxidants, and these, too, act on various pathways.
