The Truth About Soy: Why Processing and Fermentation Matter for Your Health

Dr. Ekberg addresses the common question of whether soy is beneficial or detrimental, asserting that the issue lies not with the food itself, but with the modifications and processing it undergoes. He highlights that traditional consumption, exemplified by Japanese diets, involved fermented soy, which is crucial for digestibility. Unfermented soy, with its tough proteins, is difficult for the human body to break down, leading to potential health problems. Fermentation acts as a pre-digestion process, making nutrients more accessible and introducing beneficial bacteria that support a healthy gut flora.\n\nThe podcast further distinguishes between different forms of soy. A major concern in the US is that virtually all soy is genetically modified (GMO), which Dr. Ekberg advises against for health-conscious individuals. He also points out the presence of phytoestrogens in soy, chemicals that mimic the body's hormones and can disrupt hormonal balance if consumed in large quantities. Therefore, moderation is key, even with beneficial forms of soy.\n\nA critical aspect discussed is the massive processing of soy in modern diets. Products like soybean oil are bleached, de-gummed, and denatured, stripping them of their original nutritional value and turning them into "Franken-foods." Similarly, soy protein isolate, found in protein bars and powders, is chemically extracted and used as a filler in countless processed foods, often appearing as "textured vegetable protein." These highly altered forms are far removed from whole, natural soy.\n\nDr. Ekberg concludes with clear recommendations: if one chooses to consume soy, it must be organic, fermented, and in its whole food forms like tofu, miso, and natto. By understanding these distinctions and avoiding genetically modified, unfermented, and heavily processed soy, individuals can potentially enjoy the benefits of this food while mitigating its potential downsides, emphasizing a return to traditional food preparation methods for optimal health.

"more often than not it's not necessarily a good or a bad food but what we have done to it"

"in Japan and almost everything that they ate was fermented soy because soy is a really really tough protein to digest"

"if we can't break it down now it starts to create problems"

"what the fermentation does it pre digests the food so that it's easier for us to break it down but then it also has some bacteria in it that are beneficial for us"

"virtually all soy in the US is genetically modified it's a GMO products and if you're concerned about your health you want to stay as far from those as you can"

"soy has phytoestrogens that means that they have components they have chemicals in it that mimic the body's hormones"

"in large amounts this creates problems so be moderate in the consumption with with the soy"

"just like any other food that we consume we don't want to destroy it first with massive processing and virtually all the soil that we eat is massively processed"

"it's a chemical product it's a foreign product it is used as a filler product and as a filler protein in just about every processed food"

"if you enjoy it then make sure that you get organic make sure that you eat it fermented and now you want to eat it in the form of tofu and miso and natto"
