The good, the bad, the ugly
There are plenty of pros and cons to caffeine…
If your intake of caffeine is too high, you may experience… ✱ Shakes and anxiety, due to an overstimulation of adrenaline. ✱ Insomnia, if you drink too much, or drink too much before bedtime. Caffeine can stay in your system for around four to five hours. ✱ Digestive problems. You might experience an urgency to pass a bowel motion or diarrhoea, due to overstimulation of the peristaltic movements in the bowel. Caffeine can also cause indigestion and nausea. ✱ A diuretic effect. Some believe caffeine can mildly stimulate the bladder, meaning you need to urinate more frequently.
But on the other hand… As well as providing quick bursts of energy or alertness, one study** showed that coffee can help control movement among people with Parkinson’s disease. Research also shows that coffee can help protect against liver damage. Finally, coffee can reduce our appetite, plus it contains chlorogenic acid, which slows down carbohydrate absorption as well as stimulating the hormone epinephrine, which helps break down fat.
