There is nothing wrong with eating soy, and studies show vegetarians and vegans on average have higher testosterone levels than omnivores, not less. There is no downside to consuming soy, and huge benefits.

Neither soy nor isoflavone intake affects male reproductive hormones: An expanded and updated meta-analysis of clinical studies

> Regardless of the statistical model, no significant effects of soy protein or isoflavone intake on any of the outcomes measured were found. Sub-analysis of the data according to isoflavone dose and study duration also showed no effect. This updated and expanded meta-analysis indicates that regardless of dose and study duration, neither soy protein nor isoflavone exposure affects TT [total testosterone], FT [free testosterone], E2 [estradiol], or E1 [estrone] levels in men.

Phytoestrogens in soy are actually beneficial to both men and women. They are far less potent than the mammalian estrogens already in your body, and bind to the same receptors. This reduces the incidence of estrogen dependent cancers. It doesn't cause men to grow breasts. This is a weird scaremongering tactic not backed up by any science

Even strength focused athletes seem to be doing just fine on vegan diets. In fact, studies are indicating they're doing equal to or better.

>Powerlifting is a weight-class strength sport where achieving low fat mass (FM) and high fat-free mass (FFM) is desirable to improve performance. Recent studies have evaluated the nutritional considerations of different eating patterns, such as vegan diets (VD), in athlete populations. VD are a challenge for athletes who want to attain body composition changes. The aim of this case study is to report on the body composition changes and subjective feelings of a male professional vegan powerlifter following VD for six weeks. The body mass of the powerlifter decreased from 79.3 to 77.4 kg (2.39%). Along with this, FM decreased from 15.0 to 11.4 kg (24%). Conversely, FFM increased from 64.3 to 66.0 kg (2.64%). Moreover, the powerlifter communicated no subjective feelings of low energy availability during training sessions. The VD might compromise adherence in a nutritional intervention which aims to improve body composition due to the nutritional requirements for fat loss. Therefore, more appropriate health assessments, including blood and psychological tests, are required for professional athletes. This short-term VD intervention was satisfactory for improving body composition and no adverse outcomes were reported.

>This study examined the effects of whey and pea protein supplementation on physiological adaptations following 8-weeks of high-intensity functional training (HIFT). Fifteen HIFT men (n = 8; 38.6 ± 12.7 y, 1.8 ± 0.1 m, 87.7 ± 15.8 kg) and women (n = 7; 38.9 ± 10.9 y, 1.7 ± 0.10 m, 73.3 ± 10.5 kg) participated in this study. Participants completed an 8-week HIFT program consisting of 4 training sessions per week. Participants consumed 24 g of either whey (n = 8) or pea (n = 7) protein before and after exercise on training days, and in-between meals on non-training days. Before and after training, participants underwent ultrasonography muscle thickness measurement, bioelectrical impedance analysis (BIA), two benchmark WODs (workout of the day), 1-Repetition Maximum (1RM) squat and deadlift testing, and Isometric Mid-thigh Pull (IMTP) performance. Separate analyses of covariance (ANCOVA) were performed on all measures collected at POST. Both groups experienced increased strength for 1RM back squat (p = 0.006) and deadlift (p = 0.008). No training effect (p > 0.05) was found for body composition, muscle thickness, IMTP peak force, IMTP rate of force development, or performance in either WOD. Using PRE values as the covariate, there were no group differences for any measured variable. We conclude that ingestion of whey and pea protein produce similar outcomes in measurements of body composition, muscle thickness, force production, WOD performance and strength following 8-weeks of HIFT.

>The vegan diet is becoming more and more popular among athletes, including professional ones. As the research and literature review described above show, it has a beneficial effect on many aspects of health. Also, many world-famous athletes admit its beneficial influence on the achieved results. However, as research shows, there are no significant differences in strength, anaerobicor aerobic strength, or endurance. A greater increase in performance after creatine loading was observed in activities based on the adenosine triphosphate / phosphocreatine system. This is explained by the lower starting concentration of creatine in vegans. Although much work has been done and much research has been done comparing vegan athletes to people who eat animal products, the differences in performance and strength remain an area of interest

Plus, when you compare matched-protein vegan and omnivorous diets (with soy protein or whey protein supplementation respectively), the changes in muscle strength and mass following an exercise intervention are the same, at least in young men.

Actually, it's better to get plant based proteins at all stages of life. And as you get older, your risk from cardiovascular diseases increases, which can be dramatically lowered by eating plant based. There is no known limit between increasing plant food and increased health benefits.

The leading driver of deforestation in both the Amazon and in general for tropical forests is beef, while 77% of soy is used as animal feed to the extent that, in the EU for example, it takes between 1 and 2 kilograms of soy protein to produce a kilogram of edible protein from beef, dairy, pork, or poultry. In other words, replacing all the meat people consume with soy products would reduce total soy consumption, and that's before you consider the other human-edible feed crops involved in livestock production and that other non-soy meat alternatives exist.

Soy consumed directly by humans is not the problem here; soy used as feed is.

That's a lot of protein!

Various studies have shown high-quality protein like whey maxes out MPS at a mere 20g in healthy young men. That's equivalent to about 3 large whole chicken eggs, including the yolk as it contains half of the aminos.

Whole eggs beat egg whites: https://pubmed.ncbi.nlm.nih.gov/30133322/

Soy takes nearly twice that amount in some studies. Although if you mix plant proteins to get a better complete (aminos) protein then 30g of blended (one study used wheat, corn and pea protein isolates) isolated plant proteins can match 20g of isolated whey.

Whey also promotes prolonged post-exercise phosphorylation vs soy (4 vs 2 hours): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4324640/

You're link is looking at a fairly high protein intake(like 25 percent). So MPS is going to be maxed either way. With only high-quality animal proteins we can likely get the same results with 10 percent protein, and avoid the extra oxidation and urea production from excessive protein consumption.

No problem, I apologize too, I wasn't intending to start a fight haha. I used to be vegetarian until I developed food sensitivities to basically everything, and I've bounced around in both the vegan and anti-vegan subs trying to dig up clues about the optimal diet for me. I've seen the arguments about soy from both sides and I know how inflammatory the debate can get. My personal experience is that I have reactions to eating even small amounts of soy, which takes that away as a protein option. I learned from my doctor that soy sensitivity is more common than people think saved often gets missed because there's soy oil in basically every processed food in the US, and people don't think of food that's supposed to be healthy like soy as something that could be causing their symptoms.

I ask about tempeh because it’s fermented soy, which many people report does not cause any of the intolerance reactions of regular soy. It would be interesting to compare the two.

on another note:

the main reason these studies are even done (like the one in this review) is because so many anti-vegans think vegans don't get enough protein (which is very ignorant, on so many levels).
they also like to use terms like "soy boy" as a derogatory quip - which is also very ignorant, because the reasons they use that as a taunt has been proven wrong and can easily be countered with facts.

Data shows that vegan men have just as high if not higher testosterone levels while simultaneously having a low risk for prostate cancer

In a well characterized national database, the plant-based diet index is unable to predict testosterone levels. Plant-based food content in diet is not associated with serum testosterone levels.

There is little evidence from intervention studies that diet is related to serum androgen levels, with changes to both low-fat and high-fat diets having been reported to reduce testosterone, FT and DHT concentrations over the short-term. Data from observational studies do not support the hypothesis that a diet low in saturated fatty acids is associated with lower androgen concentrations. Indeed, there is a tendency for testosterone levels to be slightly higher among vegans than meat-eaters, most probably as a direct response to an elevated SHBG concentration. A vegetarian and/or low-fat diet also has not been shown to influence LH levels, further implying that effects on androgens are insufficient to provoke a gonadotropic response. Given the absence of clear effects of diet on androgens, the lack of dietary effect on oestrogens would be expected because circulating oestrone and oestradiol in men are largely derived from peripheral conversion of androgens. One explanation as to why diet does not appear to elicit substantial differences in circulating androgen levels is due to the body's natural feedback mechanism to maintain the internal environment. Indeed, the small increase in testosterone concentration observed among vegan men is almost certainly caused by the increase in SHBG, in order to maintain a constant level of FT. However, in a much larger study, vegetarian and vegan men who were known to consume soyabean regularly were not found to have lower A-diol-g levels than meat-eaters (Allen et al. 2000). It may be that soyabean consumption among Western vegetarians is not sufficient to exert physiological effects.

Mean serum insulin-like growth factor-I was 9% lower in 233 vegan men than in 226 meat-eaters and 237 vegetarians (P = 0.002). Vegans had higher testosterone levels than vegetarians and meat-eaters, but this was offset by higher sex hormone binding globulin, and there were no differences between diet groups in free testosterone, androstanediol glucuronide or luteinizing hormone.

Vegans had 13% higher T concentration than meat-eaters (P = 0.0001) and 8% higher than vegetarians (P = 0.001); adjustment for BMI reduced these differences to 6% (P = 0.07) and 7% (P = 0.02), respectively. The results did not support the hypothesis that meat-eaters have higher levels of bioavailable androgens than non meat-eaters. No differences in hormone levels were found between meat-eaters and lacto-ovo-vegetarians, suggesting that vegetarian diets may not alter prostate cancer risk, but the relatively low IGF-I levels in vegans might reduce their risk of prostate cancer

The U shaped curve, ie reduction of mortality in light to moderate drinkers, is only found in study's which lump livelong abstainers, ex drinkers, ex binge drinkers, elderly ex drinkers and sick ex drinkers all into one category.

But when you control for these factors the curve disappears.

Many studies have same thing with smoking. For example, one study found that quiting smoking at 30 was associated with higher rates of early mortality than quitting at 50.

Does that mean smoking longer is beneficial? Of course not. The most probable justification for these results is simply that those quiting at age 30 were much more likely to be previous chainsmokers and/or have had some heath problem causing them to quit so much early

Moderate Alcohol Use and Reduced Mortality Risk: Systematic Error in Prospective Studies and New Hypotheses

Estimates of mortality risk from alcohol are significantly altered by study design and characteristics. Meta-analyses adjusting for these factors find that low-volume alcohol consumption has no net mortality benefit compared with lifetime abstention or occasional drinking. These findings have implications for public policy, the formulation of low-risk drinking guidelines, and future research on alcohol and health.

A substantial progressive decrease in the mortality rates among non-smokers over the past half century (due to prevention and improved treatment of disease) has been wholly outweighed, among cigarette smokers, by a progressive increase in the smoker nu non-smoker death rate ratio due to earlier and more intensive use of cigarettes. Among the men born around 1920, prolonged cigarette smoking from early adult life tripled age specific mortality rates, but cessation at age 50 halved the hazard, and cessation at age 30 avoided almost all of it.

Pooled analysis of all identified studies suggested an association between alcohol use and reduced CHD risk. However, this association was not observed in studies of those age 55 years or younger at baseline, in higher quality studies, or in studies that controlled for heart health. The appearance of cardio-protection among older people may reflect systematic selection biases that accumulate over the life course.

Alcohol's contribution to cancer is underestimated for exactly the same reason that its contribution to cardioprotection is overestimated

Alcohol—a universal preventive agent? A critical analysis. The evidence for the harmful effects of alcohol is undoubtedly stronger than the evidence for beneficial effects.

A sophisticated campaign by global alcohol corporations has promoted them as good corporate citizens and framed arguments with a focus on drinkers rather than the supply of alcohol. This has contributed to acceptance in the global governance arena dealing with policy development and implementation to an extent which is very different from tobacco. This approach, which obscures the contribution supply and marketing make to alcohol-related harm, has also contributed to failure by governments to adopt effective supply-side policies.

>Ain't that the truth! I once had to explain to my father that elemental lithium in the water and lithium citrate the anti psychotic medication are not the same thing

Elemental lithium doesn't even naturally occur on Earth at all. Let alone in the water supply.

And I'm not sure why you're saying the lithium salts in water/food are different from those in medications.

The World Health Organization recognizes lithium as a nutritionally essential trace element which can be safely consumed through drinking water, plant-based foods, or very low-dose supplementation.

Naturally occurring lithium in water supplies is associated with low levels of suicide.

If you're referring to intoxication that can happen when there's high concentrations of lithium salts in water supplies and trying to suggest that that doesn't happen with medications then that's it correct either.

Lithium salts are used mainly for acute mania and prophylaxis of recurrent bipolar and unipolar affective disorders. Toxicity may occur either during maintenance therapy or following acute intoxication. Lithium salts may cause hypothyroidism, which may aggravate the ataxia. Acute intoxication may affect the cardiovascular, renal, and/or nervous system. The spectrum of neurological deficits is broad: coma, seizures, coarse tremor, hypokinesia, rigidity, hyperreflexia

Lithium is widely distributed on Earth but does not naturally occur in its elemental form due to its high reactivity. Trace amounts of lithium are found in virtually all rocks.

Nutritional lithium, consumed through drinking water, plant-based foods, or low-dose supplementation, is a well-tolerated naturally occurring nutrient. The World Health Organization recognizes lithium as a nutritionally essential trace element

This synthesis of ecological studies, which are subject to the ecological fallacy/bias, supports the hypothesis that there is a protective (or inverse) association between lithium intakes from public drinking water and suicide mortality at the population level. Naturally occurring lithium in drinking water may have the potential to reduce the risk of suicide and may possibly help in mood stabilisation, particularly in populations with relatively high suicide rates and geographical areas with a greater range of lithium concentration in the drinking water. All the available evidence suggests that randomised community trials of lithium supplementation of the water supply might be a means of testing the hypothesis, particularly in communities (or settings) with demonstrated high prevalence of mental health conditions, violent criminal behaviour, chronic substance misuse and risk of suicide.

Lithium salts are used mainly for acute mania and prophylaxis of recurrent bipolar and unipolar affective disorders. Toxicity may occur either during maintenance therapy or following acute intoxication. The most common side effect of chronic treatment is an enhanced physiological tremor affecting mainly the hands. Lithium salts may cause hypothyroidism, which may aggravate the ataxia (see also Amiodarone). Acute intoxication may affect the cardiovascular, renal, and/or nervous system (Simard et al., 1989). The spectrum of neurological deficits is broad: coma, seizures, coarse tremor, hypokinesia, rigidity, hyperreflexia. High fever is common during intoxication. A neuroleptic malignant syndrome is often suspected since neuroleptics and lithium salts are often administered in combination in psychiatric patients. Although neurological signs are usually reversible after acute intoxication, patients may exhibit a severe cerebellar syndrome with scanning speech, tremor, and ataxic gait (Manto et al., 1996). Intensive care monitoring is recommended to prevent irreversible sequelae
