What natural chemicals have endocrine activity?
There are natural chemicals in plants that have hormone-like activity. These chemicals, mostly phytoestrogens, are found in high levels in broccoli, cauliflower, soybeans, carrots, oats, rice, onions, legumes, apples, potatoes, beer, and coffee. Most phytoestrogens have weak activity (low potency) and people who consume diets rich in these substances may have a reduced risk of developing some hormone related diseases. However, the actual health risk or benefit of a diet rich in plant hormones is largely unknown. Some researchers argue that dietary consumption of plant hormones dwarfs the potential exposure from man made sources. Please see EXTOXNET -Phytoestrogens.
