Coffee & Health reveals new caffeine topic and vodcastPrint this page
The Institute for Scientific Information on Coffee (ISIC) has unveiled the latest topic on its Coffee & Health website: “All About Caffeine”, accompanied by a vodcast. The new section provides information about caffeine, its origins, its links with coffee, recommended levels of intake and the effects of caffeine on various aspects of health; from alertness to sports performance to neurodegenerative diseases.
Caffeine is one of the most widely studied components of the human diet, with extensive research drawing conclusions between caffeine consumption and a wide range of health effects.
Information outlined in the new topic includes:
- Moderate caffeine consumption, of up to 400 mg caffeine or the equivalent of up to 5 cups of coffee per day, can be enjoyed as part of a healthy balanced diet and an active lifestyle1.
- Intake should be decreased in pregnant women who are advised not to go over a daily intake of 200-300 mg of caffeine from all sources2.
- When taken in moderate amounts, caffeine has mostly positive effects, mainly on alertness3, well-being and both mental and physical endurance4 performance.
- Caffeine is a mild central nervous stimulant and lifelong caffeine consumption may decrease the risk of neurodegenerative conditions such as age-related cognitive decline, Alzheimer’s Disease5,6 and Parkinson’s Disease7.
- Caffeine does not seem to have significant adverse effects on cardiovascular function8.
- It has been shown that caffeine does not lead to dehydration9 or to significantly affect bone health10 or gastro-intestinal functions11.

Ask the expert – new vodcast
Alongside the new topic, ISIC has launched a vodcast on caffeine, in which Dr Astrid Nehlig, Research Director from the French National Medical Research Institute (INSERM) joins Dr Trisha Macnair, hospital physician and health journalist, to discuss commonly asked questions and existing research on coffee, caffeine and health.
Dr Nehlig comments “Caffeine is found in some 60 plant species including cocoa, mate, guarana, tea and coffee. As such it is naturally present in products such as coffee, tea and chocolate. It is a mild central nervous system stimulant and therefore it has some implications for health, such as increased alertness and improved physical performance. Whilst there are no European guidelines for caffeine intake in the general population at present, most people consume a level that they are comfortable with and based on the research that has been done, most people should continue to enjoy their daily cups of coffee”
