The food plan in the book The 7 Principles of Fat Burning has as one of its goals reducing in your food supply chemicals that mimic estrogen (fat making hormone). Certain foods increase estrogen and others decrease it.

There’s one group of foods that is antiestrogen and antitoxin, called cruciferous (cabbage, broccoli, cauliflower, radish, kale, Brussels sprouts, etc.). Cruciferous comes from the Latin word crux, meaning cross, since the flowers of these vegetables are shaped like a cross. If we’re dealing with chemicals in the body, it makes sense to consume as many of these vegetables as possible or take them in whole-food supplement form.

To make a natural cleaning fluid for washing vegetables, mix one-third of a cup of apple cider vinegar in a gallon of water. This will remove some superficial chemicals, although nothing can remove the internal chemicals. Also, break off and discard the outer leaves of leafy vegetables.

Trim the fat from meat and the skin from poultry and fish if they are commercial. Also, if given a choice between commercial fish and commercial meat, go for the fish. It takes 60 pounds of pesticide sprayed feed and hay to produce 1 pound of edible beef, not to mention growth hormones given throughout the lifetime of the cattle. It takes only 1 pound of feed to produce 1 pound of edible fish hence fewer hormone-disrupting chemicals.
