Tofu is fairly high in protein and low in fat. How come it isn't mentioned more as a good source of protein? It makes me wonder if there is soem reason it would not be considered a good protein source.

It isn't as highly absorbed by the body as egg whites, chicken breast, cottage cheese, or whey protein. When you're lifting weights, you need to look at protein sources that can build and repair muscle tissure. But, if you're a Vegetarian than I would definitely consider Tofu as a great protein source.

Thanks for the info. I thought there must be some reason more people were not using it. I was looking into it mainly because I am trying watch what I am eating.

Fermented soy products are fine as a source of protein. Although their bioavailability is lower than eggs/meats it is still very capable of being used in muscle anabolis (and on a side note, so are the proteins from other legumes/nuts/grains etc). Soy powders/isolates that have been processed correctly are fine too.

There is quite a debate about estrogen levels and soy (which is what tofu is made of). Would a bodybuilder want to eat a lot of tofu since estrogen promotes fat storage? Especially with regards to a female bodybuilder who is already on birth control?

I think, im not sure on this, a small amount <25g a day from soy protein is actually good for you... i dont know though ... i think i may have heard that on this forum.

The first time I heard this I thought that he was being ridiculous. Upon further research I have learned that soy should be avoided. Check out these articles:

If you are going to post articles to try to support an opinion - you better pick something other than mercola. He is about as quack like as you can get.

The soy debate re oestrogens and it's effects is one that has yet to be proven. I suggest you do some further research (not through mercola) and make up your own mind. If you still concerned, then just stick with 'fermented' soy products. These have been used in Asian countries for many years and they are considered to be 'neutral' in terms of their phyto-oestrogens. Same with correctly treated isolates.

The phyto-oestrogens in most soy products (that do not have 'enhanced' phyto-oestrogen contents or those suppliments that are concentrated phyto-oestrogens) are at such a low value that they are hardly effective in 'increasing your oestrogen levels' to start with!

Also, in terms of 'making you fat' oestrogen is not primarily responsible for female fat stores - this is another 'myth' that will not die... Sure, it is important, BUT it is thought that progesterone has more importance in the areas of fat storage and hunger for females (link to discussions are here and here).

And while you are at it you can look here

Also - the phyto-oestrogens in soy are both agonists (ie: they target oestrogen receptors and act like oestrogen) and antagonists in their action at receptors (ie: They BLOCK oestrogen receptors and prevent your NATURAL and STRONGER oestrogen from binding).... What this means is that, as they are weaker in their agonist action in comparison to your natural oestrogen levels, when they bind to receptors they act like oestrogen BUT they also prevent your natural oestrogen from binding and they can help to decrease the overall action of oestrogen activity in your body!

There is more information here: in this article AND this article.

Also - if you are going to get all 'anti-phytooestrogen', then you are going to have to cut out linseed/flax from your diet as well - as this is also a rich source of phyto-oestrogens.

The effects of soy on infants - well, those studies were firstly done in rats (and, when talking about the effects of soy in rats you can not really make parallels with humans - esp in regards to protein utilisation, due to the rats increased methionine needs compared to humas...) and they are also using HIGHLY concentrated and high doses of these things. Eating Tofu/soy products (in which these bioactive compound are not concentrated) is not the same... Take a look at these articles:

Lastly, the HEALTH benifits of soy HAVE been researched thoroughly -

There is also another (BB related) article on soy here.

I know there are other artcles which show they have negative effects, but I just wanted to show the other side of the arguement.

I think according to Mercola everything will kill you.
