What is caffeine?

Caffeine is a drug that stimulates our brain and nervous system, which results in increased mental alertness. It is found in many common drinks, which include coffee, tea, energy drinks and soft drinks. However, this sneaky substance can also be found in foods like chocolate (is this why it is so addictive?) and sports supplements.

As a general rule, 400mg of caffeine per day is suggested. This equates to about 2-3 espressos (depending on the size), or 6-7 green teas.

Benefits of caffeine

Caffeine is one of the most extensivelywoman with coffee investigated drugs, due to its popularity within the community. The evidence shows that if consumed in healthy amounts, caffeine can have a magnitude of health benefits.

These include:

  • A reduced risk of type 2 diabetes
  • Improved management of Parkinson’s disease
  • Increased alertness and focus
  • Improved exercise endurance and power exertion
  • Mild fat burning effects

Consequences of caffeine

However, there is always a flip side. Not all caffeine-rich fluids contribute to positive health outcomes, like energy drinks, soft drinks or iced coffees. These drinks generally have a large amount of sugar and saturated fat, which increase our risk of cardiovascular disease, type 2 diabetes and obesity.

It’s also important to note that if we have too much caffeine, we can experience unpleasant outcomes and symptoms.


These include:

  • An increased heart rate
  • An increased risk of anxiety
  • Diarrhoea
  • Difficulty falling asleep or insomnia


In some populations, caffeine intake is not appropriate. Athletes, children, pregnant women, those who are breastfeeding and those with mental health conditions (such as anxiety), should consider limiting their intake. However, caffeine can still be part of a healthy diet and does not require extensive restriction. We do not need to be mindful of our intake and where we are sourcing the caffeine from.
