I was listening to a vegan podcast yesterday and something was mentioned about a book written about the evil of soy. TVP (textured vegetable protein) was specifically mentioned as BAD, but tempeh, soy sauce, miso, tofu (organic) were okay. Does anyone have more info on this? TVP has been a fav meat substitute of mine for making sloppy joe's and chili. Would hate to know it's evil.
Yes, the soy dilemma is quite disconcerting. The problem is that "bad" soy foods (such as TVP, non-organic, or GMO tofu) release phytoestrogens. This is (basically) a chemical version of the estrogen hormone. Now, it would not be so bad if only soy based food (tofu etc) contained phytoestrogens, but because most of the commercially processed food that the majority of people eat contain soy as a byproduct For men this means lower testosterone levels (FYI - another sneaky source for phytoestrogens is microwaving plastic). There are also correlations between soy and infertility and/or changes to a woman's mentrual cycle. Soy products also activate an enzyme (trypsin), which do not allow the protein to be digested.
In terms of the scarier statistics linked to soy - like thyroid depression and cancer - remember these are correlation - not causalities. This means that eating soy does not necessarily cause cancer, but there is a trend between people who eat soy and rates of cancer.
The key is to look for a form of fermented soy - miso, soy sauce, and tempeh (as you mentioned). Essentially the fermentation process transforms and eliminates the trypsin enzyme. Also, edamame or baby soy beans are also a safe soy alternative, because they are "young" soy beans and do not contain the trypsin enzyme, although they do have the phytoestrogens (less than TVP though).
Ultimately, try to limit your soy to 1-2 servings per day maximum. You should never rely heavily on soy as your major source of protein (as I believe Alicia says in The Kind Diet book). You can google the soy issue, but be wary of scare tactics (i.e. "Why Soy is Evil"). Always consider the source and read both sides of the story. Also, if you're looking for a good meat replacement for chilli try seitan (vital wheat gluten). If you have a gluten intolerance I have seen gluten free versions.
Marisa - thank you so much! Since posting this I've started learning more about GMOs - something I knew virtually nothing about until starting this healthy journey. Can you believe I live just around the corner from Monsanto!!! Ugh. What a scary place that is. They even have their own exit and road named after them with locked gates and tight security.
Anyway, I will print your info to keep handy. I am trying to eat whole foods and am eliminating plastics from my life altogether. I'm not a huge tofu fan so the items you recommended are regulars in the menu queue. I used the tvp as a sub for meat in sloppy joe sandwiches, but find I can crumble up veggie burgers or tempeh just as easily - I've found some that are not overly processed and are made up of grains not tofu.
I am sorry to suggest that your information is based on suspect sources. It is exactly those populations that consume the most soy that enjoy the greatest protection from cancer and several other common disorders.
As far as trying to sell sheepskin boots, you may also wish to properly research the site you try to spam.
I have not closely followed the soy debate as most of my protein comes from (non-soy) beans due to cheapness and my own taste preferences. (I love beans!) Nevertheless, I just read an article in Time magazine discussing a recent clinical trial regarding estrogen-sensitive breast cancer and soy. (This is the type of breast cancer that some people have speculated may respond to the phytoestrogens in soy). Anyway, the more tofu the participants ate (and some ate huge amounts) the lower their rates of recurrence for this type of cancer...exactly opposite what people have been worried about. Here is the passage & article for anyone who is concerned about their soy consumption:
"Now researchers from China report that soy lowers the risk of recurring breast cancers among women with estrogen-positive tumors, just the cancers that might be more sensitive to soy's tumor-promoting effects. Comparing the volunteers who ate the least amount of these foods including tofu, to those eating the most (eight times the daily dose), the researchers found that the high consumers lowered their risk of having a recurrent breast tumor by 33%."
Beary - That is precisely why I attempted to stress the importance of noting the difference between correlations and causality. I was not suggesting soy causes cancer, merely that it has been shown that a correlation between the two exists. Moreover, your point is that there is a correlation with the depreciation of cancer and soy, but again, this is correlation not causality.
All information is going to be skewed, but nobody has proved that soy causes cancer or prevents cancer. It just that when newspapers represent studies they often lead the reader to believe that there is causation when there is actually none (sorry, as an academic and writer I find this extremely frustrating to me). On a side note, I read an article (which I wish I hadn't) comparing the cholesterol levels in an egg yolk to that of a double down. The article actually tried to suggest eating a double down was better than eating an egg. Now, I know the kindlife supports veganism, but I just thought this was an interesting example of how media and studies skew their results. Although I am against eating animal products and byproducts, there is no way that I can believe an egg is worse for you than a double down. I wonder if KFC paid for that study?
