Animated video explains the science behind coffee consumption and brain function
The Institute for Scientific Information on Coffee (ISIC) has launched its latest animated video which explains the science behind coffee’s effect on the brain. It explores the role caffeine can play in alertness and performance, as well as reviewing individual sensitivity and recommended intake levels.
Caffeine is considered to be the main component in coffee that impacts brain function. Extensive research has shown beneficial effects of caffeine in the diet, such as improved attention1, alertness1 and physical performance2.
The European Food Safety Authority (EFSA) concludes that a 75mg serving of caffeine helps to increase attention and alertness1. Although caffeine content will vary according to processing and preparation, a typical cup of coffee provides 75-100mg3.
The video details how after drinking a cup of coffee, caffeine is absorbed into the blood stream and transported around the body to the brain. In the brain adenosine acts as a central nervous system depressant and promotes feelings of tiredness4. Due to its similar structure, caffeine may bind to the adenosine receptors, acting as an imposter and blocking the actions of adenosine, leading to feelings of alertness4.
Research suggests that coffee and caffeine may improve alertness in situations which require sustained concentration, such as long distance driving5 and driving at night6, and may be effective in improving performance in people who work shifts or are suffering from jet lag7.
Genetic variability can impact how individuals metabolise caffeine8,9, as can age (younger people seem to be less sensitive than older people)10. Regular coffee drinkers may be less sensitive to the effects of caffeine, and if someone drinks more coffee than they usually do, it may affect sleep patterns or lead to hyperactivity11. These effects are usually short lived once a person returns to their regular pattern of consumption.
The European Food Safety Authority (EFSA) advises that caffeine intakes from all sources up to 400 mg per day (the equivalent of up to 5 cups of coffee) and single doses of 200mg do not raise safety concerns for adults in the general population12. Pregnant and breastfeeding women are advised to consume no more than 200mg of caffeine per day from all sources (2-3 cups of coffee)12.
