Caffeine is not just found in coffee. It’s in tea, energy drinks, soft drinks and even chocolate.
Caffeine affects the central nervous system and can boost alertness and concentration. Caffeine consumption can lead to rapid heartrate, increased blood pressure, diarrhoea, headaches and irritability.
Research indicates that a moderate intake of up to 400mg of caffeine by a healthy adult poses no health risk, especially when they’re eating a balanced diet and doing regular physical activity.
Here are some of the most common drinks that contain caffeine:
Energy drinks are a popular option to give you a boost, but they are full of caffeine. A 500mL energy drink can contain 160milligrams of caffeine.
Research shows that energy drinks can cause changes to blood pressure and heart function – these changes can be more extreme than those caused by the caffeine in coffee and tea.
According to the experts at House Call Doctor, energy drinks are also high in sugar content which can lead to weight gain and obesity, and increase the risk of heart and kidney disease, Type 2 diabetes, stroke and some types of cancer.
The amount of caffeine found in green teas varies but is usually around 35mg. You can also find caffeine in green tea smoothies so be careful when drinking these.
You will find 30-50 milligrams of caffeine in a black tea, which is typically more than green tea.
Soft drinks can contain up to 55mg of caffeine and are one of the caffeinated drinks more commonly consumed by children.
Caffeine in cocktails
Many cocktails also contain caffeine but the amount in each drink will vary. Cocktails that are based on coffee and teas will contain caffeine, as well as those that have certain soft drinks or energy drinks mixed in. Mixing caffeine with alcohol is not a good idea as it can lead to dehydration, and the liver will prioritise breaking down the alcohol and leave the sugar for later, resulting in a longer sugar high.
