Should you be drinking coffee?

Should you be drinking coffee?

Some say you should, some say you shouldn’t. I am the first to admit that when it comes to nutrition advice it can get awfully confusing! Up until recently nutrition recommendations have been fairly standard, based on the premise that everyone has the same nutritional requirements, with the small exception of gender and age group. However, recent research is uncovering that, because we are genetically unique, we may all have different nutritional requirements. Nutrigenomics looks at how individual genetic variation can have an effect on the body’s response to certain foods. 

Lets take caffeine for an example. You open up the latest health mag to see the words you have been waiting for - coffee consumption decreases your risk of disease only to open up a different magazine to see the dreaded headline about how coffee is in fact increasing your risk of a heart attack. It’s no wonder everyone is confused!

These hugely confusing contradictions may actually have some credibility according to new research, and this all goes back to the fact that we are all individuals. Thereby meaning, depending on your genetic makeup, coffee can either be your tonic or your poison (not literally- but you get the idea). Coffee is a major source of caffeine, which is metabolised by your body by the CYP1A2 enzyme. An enzyme usually carries two alleles that contribute to the way it functions. Individuals who have two copies of the CYP1A2*1A allele are ‘rapid’ caffeine metabolizers, whereas individuals who carry the CYP1A2*1F allele are ‘slow’ caffeine metabolizers.  So what significance does all this slow and fast business have on your health?

Quite simply, if you have the gene that makes the fast metabolising version of the enzyme, each time you drink coffee, your body will process and eliminate the caffeine very quickly limiting the negative effects it has on your body. Whereas if you have the slow metabolising version of the enzyme the opposite occurs. Therefore if you have the slow metabolising gene, caffeine will have a greater effect on you and caffeine in fact may increase your risk of heart disease. However if you’re a fast metaboliser it may not (outrageously unfair I know). So it literally is true - in terms of heart disease risk -  coffee can either be beneficial or detrimental depending on your genotype.  

So all very well if you know your genotype, but until genotyping becomes readily available to the average person we are just going to have to make do with what we can. It seems like your best bet is to limit your intake to about 1-3 cups of coffee per day- everything in moderation they say right? But more importantly go with how you feel. Do you drink a coffee and essentially lose the plot? Jitters, anxiousness, sleeplessness and all the rest? Chances are you probably shouldn’t be drinking it. Does coffee in moderation perk you up and make you feel good? In that case you are probably good to go benefiting from it’s rich antioxidant profile.

In saying that, coffee does increase cortisol so if you are under a lot of stress, going through a rough time or suffering from a condition such as chronic fatigue, it is probably best to cut all caffeine until that is resolved.

Sometimes listening to your body is all you need to do as it may very well tell you what you need to know!

 

Take home points:  

  • Your genetic make up determines your ability to metabolise coffee
  • People are either slow metabolisers of caffeine or fast metabolisers. The former are less likely to benefit from drinking coffee.
  • If coffee makes you feel like crap, it is probably a good indication that you shouldn't be drinking it. 
  • Coffee does have health benefits due to it's rich antioxidant profile so if it makes you feel good it is ok to enjoy it in moderation. 
  • Not really a take home note but just in case you were interested, coffee (when I don't over do it) doesn't give me any negative effects so I tend to have 4 or 5 a week & feel good doing so.
