Apart from what is mentioned in the video about genetic modification,Trypsin inhibitors, and Pytic acids ...etc, the most important imact is on Thyroid disease, and this is what SoyOnLineService.co.nz mentions about Soy-formula feeding and thyroid carcinoma:

"The statistics on thyroid disease in the US also tell a disturbing tale. Since 1990 SEER cancer statistics show that the overall thyroid cancer incidence, across all ages and races in the United States, has been subject to a statistically significant annual increase (1.4 % per annum). That increase was highest amongst females (1.6 % per annum). Also worth note is the fact that between 1975 and 1996 the incidence of thyroid cancer has risen 42.1% in the United States. This increase was particularly notable in women and most recent figures (1996) show that the incidence of thyroid cancer has climbed to 8.0 per 100,000.

And what about children? The incidence of soy-formula feeding is greater in the United States than anywhere else in the world. The National Cancer Institute (NCI) publication 'Cancer Incidence and Survival among Children and Adolescents: United States SEER Program' 1975-1995 has reported that the most prevalent carcinomas in US children and adolescents younger than 20 years were thyroid carcinomas (35.5%); more prevalent than the more publicised melanomas (30.9%). Approximately 75% of the thyroid carcinomas occurred in adolescents aged 15-19 years of age, and NCI note that "the preponderance of thyroid cancer in females suggest that hormonal factors may mediate disease occurrence". Hormonal factors includes agents that affect thyroid hormone status and Soy Online Service believe that soy-formula use in infancy is an hitherto unrecognised risk factor."
