Methylxanthines

Methylxanthines interfere with the body's ability to get rid of excessive estrogen. Cutting down on methylxanthines was the most drastic and effective change I made in my diet.

Types of methylxanthines

·         Caffeine (most commonly found in coffee)

·         Theophyllines (most commonly found in teas)

·         Theobromines (most commonly found in chocolates)

As it was difficult for me to cut chocolate completely out of my life, I have compromised by allowing myself one chocolate with less than 25mg of theobromine every couple of days, usually a candy bar or chocolate chip cookies.
