Epidemiological studies show no relationship between soy consumption and the risk of developing cancer. The most recent even show that soy consumption helps reduce the risk of breast cancer, especially when it is started early (before adolescence) and maintained throughout life*. The European Health Safety Authority (EFSA) published a report in October 2015 confirming the safety of taking isoflavones. This report concludes that there is no increased risk of breast cancer or effect on breast density, long held misconceptions. No effect either on the endometrial thickness or on the tissues at the level of the uterus after 30 months with 150 mg of isoflavones per day, which is well beyond the possible contributions by regular consumption of soy foods. For example, this is equivalent to 18 soy desserts per day! ANSES (French National Agency for Food, Environmental and Occupational Health Safety) nevertheless mentions a precautionary principle, especially in women with a history of breast cancer. It is recommended not to exceed 1mg of isoflavones per kg of body weight per day. This remains compatible with normal consumption of soy products since this threshold represents more than 200g of tofu or 1l of soy drink.
