While you probably think about this stimulant mostly in terms of that morning coffee that gives you a shot of energy, know that it can be found in an abundance of foods and drinks (and meds!) – including some you might not suspect. So, how much? Check out the image above to see!<\/p>\n
What might caffeine mean for you? Well, that\u2019s going to depend. While most people can consume up to 400 milligrams a day without side effects, or up to 200mg in pregnancy, others are more sensitive.<\/p>\n
How its effects play out in your body are related to your genes (specifically the CYP1A2 gene) which dictates how fast you metabolise it – for those who are sensitive (slow metabolisers), impacts can include nervousness, anxiety, and insomnia, as caffeine can cause a spike in the stress hormone, cortisol – as well as gut symptoms (ever had to dash to the loo after a strong flat white?)<\/p>\n
Saying that, thanks to the polyphenols in coffee – NOT the caffeine – there are potential benefits to your morning coffee. Studies have shown that one or two cups a day might lower your risk of type 2 diabetes, liver disease and certain cancers. Coffee may even have a prebiotic effect, making it beneficial for your microbes.<\/p>\n
