Re phytoestrogens (WDDTY, vol 11 no 5), there is a meaningful difference between natural and synthetic hormones, and an even greater difference between phytotherapy and phytonutrition. All natural foods, both vegetarian and animal, contain all the natural elements known to us. What is favorable about these elements is their interaction, which can be enhancing, strengthening, antagonistic, synergistic, and so on. These relationships are dynamic, and change according to the internal or external situation.
The second important difference is that no synthetic hormone or even phytohormone in recommended doses can imitate the quantities produced naturally in the body at any given time.
Hormones direct processes and the quantity of hormones determines the process. If there is a disorder, the medical industries add a hormone (a sex hormone, energy hormone or cortisone, to supposedly control inflammation).
However, the active process dictates to the endocrine glands or hormone producing tissues how much hormone to produce, how much to secrete directly into the blood, and how much of the hormone produced needs to be neutralised or released from the body.
Every hormone is delivered by the blood to a gland or tissue and receives feedback if a certain hormone is added, the level of this hormone decreases in the bloodstream and the gland is 'told' to increase its production.
But, if the hormone is not required to regulate the process, its blood level remains high. A surplus of hormones in the blood causes a slowing down or pause in the production of the hormone, and this may cause fertility problems. Dr Ilana Tzur, Kibbutz Shoval, Israel
