Recently it has been proved that drinking and eating excess amounts of cola and honey which is made from the pollen of Rhododendrons causes unusual fainting and symptoms of arrhythmia.
Mad honey poisoning means it is a disease which occurs after people consume honey contaminated with grayanotoxin, a chemical which is in nectar from the Rhododendron species ponticum and luteum. Mad honey poisoning doesn’t last for more than 24 hours, with symptoms like dizziness, weakness, nausea and vomiting, excessive perspiration.
The two potential explanations for the connection between cola consumption and low blood potassium level is that through osmotic principles the high fructose corn syrup content of cola is prevents water from being absorbed by the gut present in the throat and lead to people suffering from diarrhea in which heavy fluid ‘flush’ potassium out of the body. Additionally, caffeine present in the cola is also puts an effect on the loop of Henle in the kidneys where it reduces the amount of potassium that is being reabsorbed. In the heart extracellular potassium reduced and inhibit the potassium current in ion channels and delay ventricular repolarization that can promote arrhythmias. Symptoms of the severe form included syncope, seizures, atrioventricular block and also fatal tachyarrhythmia (due to oscillatory after potentials).
