IGF1 levels does not necessarily means that you're gonna get cancer.IGF1 is a metabolic pathway for growth, yes growth in general from muscle tissue, bones, even organs BUT.There is a huge difference from ingecting into yourself, artificial IGF1 HGH etc and causing you body to secrete it naturall.When i say naturally i'm not talking about animal products (i am a vegan btw except some use
of honey and bee pollen) animal product consumption is linked to a numerous deseases due to saturated fats, trans fats,
high concentrations of sulfuring aminos even heme iron http://www.ncbi.nlm.nih.gov/pubmed/23983135.Blaming soy protein (which btw has some great health benefits, general the soy bean) is at least wrong.Ok consuming every day 1 kg
of soy probably is not good, as NOTHING is at very
high quantities.Nothing wrong with natto, tempeh, tofu, soymilk, soybean, ans SPI.Asian people have been consuming soy for thousands
of years without negative effects.Soy and especially SPI for people who are doing serious natural bodybuilding without use
of AAS and artificial growth factors, and are also vegans believe me is a pain in the a $ $ and soy protein is maybe the ONLY type
of protein that has sufficient ratios
of amino acids, from bcaas to even
sulfur aminos (but in normal levels not the dangerous levels linked to the homocysteine rise in the blood).
Also characteristic
of the atmosphere over urban centres are substantially
higher concentrations of pollutants such as carbon monoxide, the oxides
of sulfur and nitrogen, hydrocarbons, oxidants, and particulate matter.
Concentrations of sulfate aerosols were especially
high during these years before regulations like the Clean Air Act limited
sulfur dioxide emissions that produce sulfate aerosols.
