Caffeine can be found in some most unexpected places. Apart from the usual cup of coffee, this chemical is also in tea, cola drinks, energy drinks, chocolate and cocoa. It is available as a diet pill, found in some flu medication, cellulite cream and even in shampoo.
Caffeine acts as a central nervous system stimulant and even though it is often considered bad for health, in some circumstances, it can actually be beneficial.
Caffeine can have an affect on muscles, the heart, blood vessels, kidney, lungs as well as the central nervous system and other areas of the body.
It is a stimulant and because of this people will feel more energetic and alert after consumption. This is also why you may not sleep if you have too much.
The Technical jargon
Caffeine is a nitrogenous organic compound of the alkaloid class. It occurs naturally in tea, coffee, cola, guarana, cocoa and mate. Pure coffee (trimethylxanthine) is a pure white powder or silk needles. It is odourless with a bitter taste.
Caffeine can affect people differently. This is dependent on a person’s physical size, weight and general health and the amount and regularity of consumption. Caffeine can have a different effect if combined with certain medication. (Check with your pharmacist or doctor for advice if you are taking medication before consuming caffeine containing products).
The effects of consuming caffeine can last up to 12 hours.
Caffeine contains antioxidants and can have an anti-inflammatory and anti-apoptotic action. Studies have revealed some interesting benefits to consuming caffeine.
Type 2 diabetes. Experimental and epidemiologic evidences suggest the consumption coffee offers a protective effect for people with type 2 diabetes offering multiple mechanisms of action.
Alzheimer’s disease and other neurodegenerative diseases. Caffeine can protect the brain. Caffeine was found to be beneficial for both men and women with Alzheimer’s disease and Parkinson’s disease, showing a neuroprotective effect, with further study suggested.
Depression. As well as helping to get us going in the morning and to give us a lift in the afternoon, caffeine has been found to help with mild to moderate depression. The experts haven’t quite worked out the mechanism of action yet, but one hypothesis suggested is that depression is a result of inflammation of the brain. It is thought the antioxidants and other chemicals found in caffeine, have an anti-inflammatory action.
Another theory is the psycho-stimulating effect of caffeine has a motivating action, giving back the get-up-and go. One of the characteristics of depression, is a lack of motivation.
Bowel cancer. Caffeine was found to be associated with a lower risk of colorectal cancer-specific death and overall death in people with colorectal cancer. Further studies need to be performed to determine the mechanisms by which coffee might reduce colorectal cancer progression.
Weight loss. Caffeine increases metabolic rate, improving fat burning capacity and supporting exercise performance and motivation.
Exercise performance. Caffeine has been shown to enhance endurance, strength, mood, alertness and cognitive functioning in athelets.
The amount of caffeine in products varies. An expresso may contain from 150-400mg/50ml cup, whilst a cup of tea might contain 50ml/250ml cup.
The daily limit of caffeine consumption is suggested at 400mg.
Being a stimulant on the central nervous system can mean too much caffeine can result in nervousness, agitation and anxiety. It can cause the heart beat to increase and breathing to quicken. It can deprave the ability to sleep.
Other more serious concerns include:
Caffeine is considered a drug in which habitual, excessive intake may have an addictive effect, if not a dependence. Its stimulating action (speeding up messages traveling between the brain and body) is often used to induce wakefulness, at the expense of needed sleep.
You can overdose on caffeine if large amounts are taken. 000 should be called for emergency medical attention if any of the following is experienced.
Caffeine poisoning can occur in children if too much is consumed.
If you regularly consume large amounts of caffeine (over 4 cups of coffee/day for example) you may eventually experience symptoms which may include:
It can interfere with some medication such as antibiotics, heart, asthma and mental health medicines. Discuss with your doctor or pharmacist whether caffeine could affect your medication.
Caffeine and Alcohol - Consuming caffeine whilst drinking alcohol can mask the affects of alcohol leading to drinking more than intended.
Caffeine and stimulating drugs - Taking both may increase the risk of cardiovascular problems.
If you are a heavy caffeine consumer and have decided to reduce the amount in your daily intake be aware you may experience withdrawal symptoms. These can include headaches, fatigue, irritability, trouble concentrating and nausea. It is suggested to reduce caffeine intake gradually over a few weeks to avoid symptoms.
Make the switch to water, herbal drinks such as chicory root, dandelion root, peppermint teas, carob, milk drinks. fruit and vegetable juices or decaffeinated coffees and as alternative to chocolate.
