What is caffeine and where do we get it?
Caffeine is a stimulant that stimulates the central nervous system.
It is found in coffee, tea, cocoa, chocolate and energy beverages and shots containing ingredients such as guarana (a Brazilian plant whose seeds are high in caffeine) and yerba mate (a South American herb used to make tea). You can also find caffeine in pills, some alcohol beverages and sports gels.

What are some of the surprising health benefits of caffeine?
Contrary to popular belief drinking some coffee or having moderate caffeine in your diet as an adult may not be so bad after all.
- Caffeine is, of course, best known for boosting mental alertness and helping lessen fatigue.
- Since caffeine stimulates the central nervous system and increases alertness, it can be performance enhancing for athletes (especially endurance athletes in sports such as triathlon and cycling). Caffeine before or during sports can help delay fatigue, increase endurance and simply make an athlete feel like the exercise is less difficult overall.
- Research has also shown that moderate coffee consumption (3-4 cups per day has been linked to a longer lifespan. Other research has found that coffee drinkers may have a lower risk of Parkinson’s disease and Type 2 diabetes.
There has also been positive research specifically about green tea such as matcha green tea:
- Research shows drinking green tea may be good for reducing heart disease, lowering the risk of cancer (such as prostate, breast and stomach cancer) and may improve cognitive function in older adults.
- Green tea contains beneficial antioxidants that can help protect your cells from damage and prevent disease.
If you don’t like coffee or tea that is not a problem, but if you do enjoy caffeine containing beverages there is no need to feel guilty if you consume these in a reasonable amount.
How much caffeine is too much?
- Adults over 18 years of age are advised to have less than 400 milligrams of caffeine per day (6 milligrams per kilogram of body weight per day). This is the amount found in approximately two to three, 8-oz (250 ml) cups of coffee.
- The above amount of caffeine has been studied in research for healthy adults and is NOT associated with adverse effects such as toxicity, changes in behavior, cardiovascular effects or increased incidence of cancer. This amount of caffeine also does not negatively influence your bone health as long as you are consuming enough calcium from foods and/or supplements.
- Some people are more sensitive to caffeine than others. If too much caffeine is consumed it can cause insomnia, anxiety, irritability, rapid heart rate, stomach upset and headaches.
- If you are consuming too much caffeine, reduce your intake gradually to avoid uncomfortable symptoms such as fatigue and headaches.
- Caffeine passes through the placenta to a baby and babies take longer to process caffeine.
- Pregnant women are advised to consume less than 200-300 milligrams of caffeine per day. This is the amount in about one or two 8-oz (250 ml) cups of coffee per day.
- Health Canada recommends kids age 12 and under consume no more than 2.5 mg/kilogram of body weight. Although weight is highly variable among children, this is approximately:
- 45 mg/day or less for kids aged 4-6 years
- 62 mg/day or less for kids aged 7-9 years
- 85 mg/day or less for kids aged 10-12 years
- Although no current guideline for teenagers exist, a guideline of 2.5 mg/kilogram of body weight is also likely a good idea.
Choosing the healthiest caffeinated beverages

If making at home start with 1/4 cup of coffee beans steeped in 1 cup of water and adjust with more or less water depending on how strong you like it.

- Optional: Add some nutrition and natural sweetness with dates, banana, cinnamon or ginger.
