IsItBullshit: Soy milk is healthier and has more nutrients than regular milk.
As far as I'm aware the transportation is a downside of soy milk. Although unsure how applicable it is in the US as it is here in the UK. Soy beans don't grow here so soy beans/milk is imported. My Mrs is vegan and uses oat milk due to this, and I have milk delivered from a local milkman/dairy. Oat milk is fattier than soy, but it does taste creamier (out of the milk based substitutes it was the one I preferred), plus oats grow in the UK so reduces environmental impact through transportation.

r/nutrition on Reddit: Any downside to soy milk?
November 15, 2021 -

I have about 4 grocery stores in my vicinity and they all stock maybe 1 kind of soy milk and then like a dozen kinds of almond or oat milk. To me though the soy milk is by far the tastiest and has way more protein than the rest. I'm wondering if there's some reason perhaps it's not as popular? Is it just the stigma of soy turning men into women? The Silk Dark Chocolate in particular is particularly good.

Soy milk is a great milk alternative. Neither soyfoods nor isoflavones warrant classification as endocrine disruptors: a technical review of the observational and clinical data Abstract: Soybeans are a rich source of isoflavones, which are classified as phytoestrogens. Despite numerous proposed benefits, isoflavones are often classified as endocrine disruptors, based primarily on animal studies. However, there are ample human data regarding the health effects of isoflavones. We conducted a technical review, systematically searching Medline, EMBASE, and the Cochrane Library (from inception through January 2021). We included clinical studies, observational studies, and systematic reviews and meta-analyses (SRMA) that examined the relationship between soy and/or isoflavone intake and endocrine-related endpoints. 417 reports (229 observational studies, 157 clinical studies and 32 SRMAs) met our eligibility criteria. The available evidence indicates that isoflavone intake does not adversely affect thyroid function. Adverse effects are also not seen on breast or endometrial tissue or estrogen levels in women, or testosterone or estrogen levels, or sperm or semen parameters in men. Although menstrual cycle length may be slightly increased, ovulation is not prevented. Limited insight could be gained about possible impacts of in utero isoflavone exposure, but the existing data are reassuring. Adverse effects of isoflavone intake were not identified in children, but limited research has been conducted. After extensive review, the evidence does not support classifying isoflavones as endocrine disruptors.

Importantly, the results of single meal studies, which are typically used to determine bioavailability, may exaggerate the effect of enhancers and inhibitors of mineral absorption (138).
