Food that is high in nitrates are hazardous for young infants and can give rise to “spinach poisoning”.

Eggplant may interfere with the test result of carcinoid tumors and it is advisable to stop consuming eggplant at least 72 hours before the test. This is because eggplant contains serotonin, which also gets secreted from the carcinoid tumors. Stopping eggplant consumption 72 hours prior to testing ensures that the current reading of serotonin ( as secreted by carcinoid tumors) comes into the report and there is no interference of serotonin ( released by the eggplant).
