On most lists of products containing estrogen, animal products like milk and beef are at the very bottom. Milk, for example, is said to provide 1.2 micrograms of estrogen per 100 grams.
Depends on where you go to get your fix. Starbucks Cold Brew (in stores nationwide since May 2015) and Dunkin' Donuts Cold Brew (in stores nationwide since August 2016) retail for different prices. Cost: Roughly $0.20 per ounce. $3.25 for a grande (16 fluid ounces) according to Starbucks.
Starbucks estimates are based on a 16-ounce grande coffee at $2.10 per cup. Home-brewed estimates are based on an approximate $8 cost of a 34 ounce can of Folgers or Maxwell House, which amounts to about $.08 per 16 ounce serving.
