The advantages of caffeine are that it can make you go to the loo, wake you up and burn fat, however it comes with a much bigger downside.
According to the food standards of Australia and New Zealand and the National Foods Tea Centre Sydney, caffeine can prevent pregnancy, cause miscarriage, increase stress and lead to heart disease. Guidelines in pregnancy are 200 milligrams or less a day. Caffeine increases inflammation in the gut, irritates the bowel and contributes to irritable bowel syndrome, affects digestive juices negatively; it is acidic, causes heat in the stomach contributing to ulcers and affects the nerves of the whole gut. It stimulates adrenaline and cortisol which in excess can make you a nervous wreck and it decreases immunity.
It raises bad cholesterol and homocysteine leading to heart problems; 5-10 cups a day can cause a heart attack and as constipation puts pressure on the heart, those with chronic constipation are more susceptible. It reduces mineral absorption when taken near food, especially calcium and the polyphenols in coffee and tea reduce iron absorption.
Strength of caffeine per cup- 600mg daily is considered safe for adults but far less is advised if you are anxious, stressed, have insomnia or a gut problem. In most gut problems caffeine is best left out of the diet altogether. Some of you can handle small amounts of green tea which has beneficial antioxidants. Caffeine is very dehydrating and water is necessary for a healthy bowel movement; clearing toxins and many metabolic processes are dependent on water.
