yo guys and girls

what do you think about guys taking soy protein

one of my boys is taking soy and he swears by it, he says its healthy for guys. even though we all know that soy has high levels of estrogen which is not too cool for guys

wanted to see what everyone has to say.......

Posted by: Mudge

Its similar to the situation with vegetable oil. It was healthy at one point, but due to processing it becomes unhealthy.

bottom line is soy is shit.

Posted by: BigBallaGA

why was this moved ?!?

soy protein is a supplement, so it should have stayed there !

Posted by: Mudge

Protein is part of your diet, protein is food, food is not a supplement. I have always considered protein powder as part of a diet (no I did not move it).

It is hard to know what to believe sometimes isn't it, sometimes the benefits outweigh the small detractions, so who knows. The only time I tried soy it was the most horrid tasting thing I had ever experienced, including cod liver oil. I hear it has been much, much improved since then.

I get whey for $19.99/6 pounds, so I have no reason to look elsewhere for now.

The link says very well where it came from dude, look at the top of the page

who cares where the thread is, soy is still shit!

Posted by: BigBallaGA

hahahahhhaahah soy it is !! kiddin

stick to whey

Posted by: Premo55

There's nothing wrong with soy protein. I know people who are just as muscular and have testosterone levels that are comparable or even higher than whey-using bodybuilders. Personally I make my own protein blend with soy protein isolate, whey isolate, whey concentrate, hydrolyzed whey, milk protein isolate, egg white albumen powder and casein, which I only ever use post-workout. I use soy milk instead of milk at all times and eat tofu twice a week as well.

Peace.

yip i spoke to the guy who runs muscle science and he says you will get the same results whether you use whey or soy.. you'll find that article made about a hundred stupid statements but didnt back them up with any scientific evidence.

Why Soy Can Damage Your Health

Posted by: Premo55

^^ Yeah okay, so why is it that I know vegan and veggie bodybuilders who experience great results without meat protein and whey, AND who exhibit serum testosterone levels that are perfectly comparable with bodybuilders who ritualistically avoid soy? It all comes down to desire, hard work, training intelligently, how clean your diet is and rest. I increasingly grow wary of the notion that any protein is better than another.

Peace.

Peace.

So, you actually know bodybuilders that eat soy and have their T levels measured and report these results back to you?

Interesting to say the least.

These bodybuilders that you speak of, if they also told you that they do not use free weights, only machines, would you also conclude that using machines is the best way to train, or that it does not matter both will work the same?

You do not believe that proteins have different bv's? So, the protein found in an egg is equivelant to the protein found in a peanut?

Posted by: Mudge

Yes, lets see some comparitive blood tests please, otherwise I can only assume that you are making assumptions. I have a hard time believing that people actually got blood tested before and after using soy protein just for kicks.

Comparing T levels from one person to the next means nothing, it must be done with the same person. One person may have a natural T level of 300 and another 750, this doesn't tell us anything conclusive about thier diets.

Premo,

Go ahead and mock the great vegans, "use Soy"

Posted by: Premo55

Yes I think veganism is silly too, from my personal perspective, seeing as how I eat two steaks a day, but really I've seen vegan bodybuilders with phenomenal body composition, and have achieved that much through hard work, dedication, diet and intelligent training (compound movements, powerlifting movements etc.). Soy is comparable to non-veggie alternatives, how else would you explain the success of vegetarian bodybuilders?

Peace.

The meat industry is pretty ugly if you read about it, at least for some, it certainly has the gore aspect down. Treatment of the animals in general is pretty bad, and I'm not animal rights guy either but the things many of these animals go through is just discusting.

With that said, I love meat, and no I'm not a hipster nor do I toke the peace pipe.

Posted by: Jodi R

i'm with premo on this.

and you cant really compare the protein from an egg with the protein from a peanut .. you'd have to compare say 20g protein from eggs with 20g protein from peanuts.. whats the diff ??

I was talking about the bv of different proteins. Obvously one cannot argue that the bv is the same between an egg and a peanut, that was my point.

Posted by: Mudge

I can only think of one vegetarian pro-bodybuilder (former).

Posted by: Randy

Yeah, the mad cow situation is pretty bad. It definately is sad the way they treat many of the animals too. Hopefully there is some good that will come out of this though. Stiffer regulations and more frequent monitoring of all processes. Most important some definate changes to help avoid mad cow or anything like it in the future. After all, happy cows are supposed to come from California...

Same place I get it.

i bought soy once......then read about it...never used it....cause all readings said soy sucks.......

Posted by: Yeah Buddy!

is it true that soy isolate can boost thyroid function and keep BMR from going to low after months of dieting?

P.S.

Posted by: Randy

Not sure bro, I don't use Soy. I use 100% Whey.
The brand is Pro-rated.

Posted by: Mudge

Soy negatively impacts thyroid function from my reading. Either way, I have directly used thyroid medications before, if you think a modest thyroid boost is going to make a difference you are dreaming.

Posted by: CowPimp

I try to use as many different sources of protein as possible. Occasionally I will grab a soy protein drink if I am out and don't have access to the foods I would like to be eating. As long as you don't take use soy as on of your primary sources of protein, I can't see it hurting...

Posted by: Eggs

Lets be realistic though... the main issue at hand is whether the sky is truly falling.

Or as most people here think, that Soy makes your dick fall off.

Thats not the case. As to Dr. Mercola... Mudge, whats your blood type? I bet I could give you a link to a Dr that says you're only supposed to eat grains and what not. So which Dr is right?

Regardless... Dr Mercola also says that we should lower our underground vegetable carbs. Does that mean I should cut out carrots, potatoes... etc? What exactly can I eat any more? Thats what I want to know... because if I follow all the Drs diet advice thats out there these days, I very well might spend the rest of my days nibbling on crumpets and looking like a damn sissy.

Soy wont kill you. Is it as good as whey? No... I do believe whey is superior. But people are over reacting to soy and being plain silly.

As to peoples estrogen levels increasing when they take soy... they do so when people use roids as well and a favorable amount of estrogen isnt necessarily a bad thing. I doubt that the estrogen increase attributable to soy is anything more than miniscule.

I didn't think it could either, but then I bought drank two soy protein drinks at the same time and guess what was sitting on the floor next to my bed when I woke up the next morning...

You too? Damn... we cant let this get out or they'll all make fun of us

You're taking the estrogen level thing out of context though.

Yes estrogen is necessary for an optimal anabolic environment, however this in relation the the level of testosterone present.

If you increase testosterone then estrogen needs to be increased as well. In the case of Soy, if it is only increasing estrogen levels that is not a good thing!

Posted by: Eggs

But just a minute amount isnt going to cause gyno or anything is it? I've seen quite a few healthy people that use soy... and none of the males that I know of experience gyno. I think what our arguments really come down to are which is a better protein source.

In that we agree 100% that whey is the best.

Posted by: Prince

No, I am sure the estrogen level increase is quite small, but as a bodybuilder we would not want even the slightest increase.

I think I read somewhere that Soy Isolates do not have much impact on estrogen, but either way I avoid all of it.

Yes, whey is superior, but one should incorporate many protein sources: whey, casein, egg, meats, etc.

Posted by: Eggs

I dont usually have much soy in my diet anymore... the occasional glass of soy milk (like once every couple months when I'm visiting the family). I see what you're saying about not wanting any increase in estrogen though, as that would probably increase fat retention.

What do you think our primary protein source should be? I get some eggs for breakfast and what not... but the single highest source of protein I get is probably from whey. Along with a little casein each day and some meats. Sound workable?

Which is exactly why I feel a little soy in your diet can't hurt. It is definitely one of the smallest sources of protein in my diet, but I have some soy protein periodically.

this is part of an article (the bad part about Soy, written by Will Brink)

The Downside of Soy

So why does soy have such a bad reputation among bodybuilders? On the surface, it would appear that soy protein is pretty lousy stuff for most athletes. Soy protein has a low BV score of 74. What does that mean? There are several ways of assessing protein quality. You have the protein efficiency ratio (PER), the net protein utilization (NPU) and the biological value (BV). The PER is an outdated measure of protein quality and is not used much anymore by most supplement manufacturers or nutritionists "in the know" about protein quality. The NPU is a little better than the PER, but fails to take several important factors into account involved with proteins, such as absorption and digestibility, so it too is not used much either. That brings us to the BV. The BV is the most accurate indicator of biological activity of a protein and measures the actual amount of protein deposited per gram of protein absorbed. As a rule, high BV proteins are better for nitrogen retention, immunity, IGF-1 stimulation, and are superior for reducing lean tissue loss during various wasting states than their low BV counterparts. That is, as a general rule, high BV proteins are more anti-catabolic than low BV proteins. As most people already know, the highest BV protein available is whey protein with whole egg a close second (see chart), which is why bodybuilders and other athletes rely heavily on these two protein foods and tend to avoid soy and other proteins with low BV scores.

In addition to its low BV score, soy has several other nutritional drawbacks that make bodybuilders avoid the stuff like it was fake D-bol. One reason soy is so low on the BV scale is it is lacking in the sulfur containing amino acid methionine. The sulfur containing amino acids (cysteine being the other one) are particularly important for protein synthesis/growth, proper immune system function, and the body's production of glutathione (GSH). GSH is one of the most important anti-oxidants found in the body and protects cells and serves to detoxify a variety of harmful compounds such as hydrogen peroxide, carcinogens, reactive oxygen species, and many others. In particular, GSH is also partly responsible for keeping low density lipoproteins (LDL) from oxidizing and clogging our arteries. Several studies have shown soy protein to be inferior to whey for the production of GSH and improvements in immunity. Though soy has a reputation for reducing cholesterol in man and animals, in one study rats fed soy protein that was not fortified with methionine as 13% of total calories, had an increase in cholesterol and an increase susceptibility of LDL cholesterol to peroxidation . So not only did the rats cholesterol go up, the LDL fraction oxidized easier potentially leading to clogged arteries. It is well established that an increased susceptibility of LDL to peroxidation is an essential step for the development of atherogenesis. These rats were found to have low levels of GSH and did not grow as well as another groups of rats fed casein.

If that were not bad enough to convince you to avoid soy, it gets worse. Soy protein contains something known as "anti -nutrients" that block the digestion and absorption of many nutrients. Two of the more important anti-nutrients found in soy are Lectins and protease inhibitors. Lectins are nasty constituents of various plants and can cause all sorts of problems from interfering with the absorption of important nutrients to intestinal damage. Proteases are enzymes that assist in the digestion of proteins. Soy has several protease inhibitors that interfere with the enzyme trypsin and chymotrypsin, both of which are important for the digestion and absorption of proteins in the gastrointestinal tract. Finally, soy is rich in estrogenic compounds such as genistein and diadzein. There are over 300 plant derived phytoestrogens found that vary substantially in their physiologic effect and potency in animals and man. As any bodybuilder worth his weight belt already knows, a change in the testosterone/estrogen ratio in favor of estrogen can lead to increased bodyfat and other ill effects as it relates to the strength athletes goals.

It's funny that whey gets such a high rating on the "well-renowned" BV scale. I saw a study in which the muscle growth over a set period of time for people primarily using whey protein was about 1/3 of those who ate primarily fish.

Posted by: Prince

exactly why I said it's important to use a variety of protein sources.

Ok, here comes my car analogy again....I love it

Now you can think of this as a new car or your hot rod.
Would you want to be putting lousy gas in your car, like 87 octane? Hell no, even if you didn't notice any knocks you would still go with the good gas right? Same difference here.. Like Prince said, just knowing that Soy is less superior to whey, why use it? I'm sure there are some that just want to prove a point. For those that do, go for it

This is a bad analogy. If you analogy were accurate, then we would only use the "best" source of protein. However, we need many different kinds of protein. Could you imagine only eating whey all day long, or eggs?

I think that a very small amount of soy placed here and there in the diet isn't going to hurt, and might actually be a good thing. Granted, I wouldn't suggest making soy a regular part of your diet based on what I have learned here, but I also wouldn't be completely adversed to including it at small doses.

Yo Dudes and Dudettes i'm just chuckin my 2 cents into this raging debate on the truth of Soy!

Check out research just in that says avoid soy if you are a guy who just might want to father a mini-me one day.

and for further conjecture that Soy might mean changing your name from Dan to Daniella checkout

In the land of the free the choice is yours.

Looks like we'll have to call eggs, eggette

Posted by: Robin Hood

Ok, so this thread is really old, but I wanted to post a question. Being an aspiring female bodybuilder, is it ok to have soy protein once a day while bulking up? I also get daily protein from fish/poultry, eggs, milk, and whey isolate.

Posted by: Robin Hood

By the way, its soy isolate protein...if that makes a dif.

Posted by: LAM

you can have several servings of it if you like

Posted by: musclepump

I was never a fan of any type of Soy protein

Posted by: Robin Hood

But does it not increase estrogen in both women and men, thereby causing more fat storage? This may be ok for a bulk, but I would probably want to stay away when cutting...wouldn't I?

Posted by: LAM

that's no concern when using soy isolates, all of the phytoestrogens have been removed

Thank you soooo much! That eases my mind, considering I just bought 2 canisters of soy isolate protein without doing any research. Then I started reading this thread and got worried that I had wasted my money.

What about soy milk? Would that be a no-no?
