Drinks Sensitivities

When the body is sensitive to certain foods, there are some common symptoms to be aware of, which typically present themselves within a couple of hours. If you have symptoms on a daily basis, then start paying attention to what you regularly eat.

Many people include caffeine in their day to day lives. Caffeine is an alkaloid compound which is found especially in tea and coffee plants and is also a stimulant of the central nervous system. Caffeine affects different people in different ways. The effects that caffeine has on the body of someone who is allergic to it are not the same as for someone who has a caffeine sensitivity.

When a person consumes caffeine, it is absorbed into their bloodstream from their gut. It can then affect how different organs work. In the brain, caffeine blocks the effects of chemical messengers that normally make a person sleepy. It may also increase levels of adrenaline in the blood, which makes the brain and body more alert. For people who have a caffeine sensitivity/intolerance, the rush of adrenaline from caffeine may cause them to experience symptoms such as:

  • Digestive complaints – such as IBS, bloating or stomach ache
  • Neurological problems – like severe headaches and migraines
  • Skin issues – most commonly eczema, acne, itchiness and rashes
  • Tiredness and fatigue – a lack of energy, “brain fog” or lethargy
