Safe process to isolate protein from soy?

Answered on August 19, 2014
Created March 28, 2012 at 9:25 PM

QUESTION: Does a process exist to isolate soy protein without leaching aluminum into the product, introducing nitrates, or denaturing the protein with heat while eliminating it's trypsin inhibiting content and how legitimate are these concerns?

BACKGROUND: I know soy is not paleo and I wwould never waste my money on Visalus or any MLM company but I have a friend that was selling it and after having my facebook newsfeed spammed with ads for it I checked out the ingredients and was concerned when I saw the first (main) ingredient was soy protein isolate. It is pretty well established that soy itself is not healthy, but Visalus counters this by saying they have "taken the bad stuff out." So far she is doing well with the company and is reluctant to accept my assessment of the shakes since the company has doctors backing the product. I have started to open her eyes that money not people's health is the primary motivator here.

Below is the email exchange from a friend asking me my if my opinion of Visalus Nutritional Shakes had changed after sending me a video clip of Dr. Michael Seidman, Director of Product Research and Development for ViSalus Sciences stating that the phytoestrogens had been removed from the soy. I was originally concerned because she had young boys and I knew of soy's estrogenic effects. If there is a cleaner/safer process being used to transform soybeans to SPI than I would like to know.

The phytoestrogens were originally my main concern but weren???t the only one.

Soy protein isolate (SPI) is a waste product of soy oil manufacturing. The industrial process of extracting SPI leaches the heavy metal aluminum into the product which is toxic to the nervous system and the kidneys. The spray drying process creates a large percentage of nitrates which are believed to be cancer causing agents. SPI contains trypsin (an enzyme) inhibiting content which prevents the digestion of protein. Research on test animals indicated SPI increases their requirements for several essential vitamins and minerals and prevents absorption of others and potentially contributed to development of enlarged organs and/or caused increased deposits of fatty acids in the liver. The FDA has never approved SPI as GRAS (Generally Recognized as Safe). It was first approved for use as a binder in cardboard boxes.

Basically at best any weight loss experienced from taking Visalus is the result of it limiting your calories or is a placebo effect, but you are probably just shitting out your money. The shakes may have enough added vitamins to account for the level of trypsin inhibiting content and still have some left to be absorbed, but in my opinion it would be easier taking a multivitamin. Though there might be exceptions, any self respecting male or women trying to build or maintain lean muscle mass should choose soy, isolate or not, AS A LAST RESORT and instead would go with whey, casein, meat, milk, or eggs. Worst case scenario you are contributing, however slightly, to your body???s own malnutrition and/or susceptibility to preventable disease/s. For your obese customers the benefits of weight loss may outweigh the risks, but there are healthier and probably cheaper ways of getting there than Visalus. I don???t know if the risks are worth it for people at a healthy weight and trying to slim further or have an easy meal replacement.

I thought about flagging this comment, but it was so hilarious that I suggest preserving it, sort of like a "zoo" of sorts. Its doubtful we will see Monica again anyhow, though Monica could probably use spending a lot more time at this site learning about nutrition...

It's a trap, stay away from it. The only safe soy, is the soy you don't eat, or ferment to extract the K2 out of. Beyond that, stay away.

Better turn this into a question, or else you risk being deleted.

There is nothing nutritious in the Vi Shakes. Soy and Sucralose? Sucralose is a toxin to the liver. It's hard to rid your body of the artificial sweetener unless you do a cleanse. I did a 90 challenge and lost weight. I lost muscle too. They say it's safe for diabetics; however, they add other sugars in the mix. I don't think it's safe for diabetics, and I won't recommend it to people with diabetes.

Whole foods and exercise is the way to lose fat weight and gain lean muscle. Visalus is all about making money off of people who are gullible.

I have to agree. I have several friends who are involved with ViSalus and have already gotten their BMW's (which by the way YOU have to go and get the lease in YOUR name and if you don't qualify, you won't get one... if you DO manage to qualify -- but if something happens with ViSalus or your team and you stop making money for any reason, you better figure out how you're going to make a $600-$700 monthly car payment!!!) Yes, they are loosing weight. BUT when I questioned them about the safety of soy, EACH ONE GAVE ME VERBATIM THE SAME ANSWER! Wow. Like little automatons. So I asked the questions 'HOW are they extracting the isoflavones?' and "WHY are they using soy protein isolate when it has not been given GRAS status - and was actually DENIED GRAS status based on the FDA's concerns over lysinoalinine? They have yet to get back to me. One of them told me that he already investigated EVERYTHING and feels good about it. Yet when I asked these questions - SILENCE. I hope he asks and gets back to me with answers. I have a feeling, however, they he won't because they won't get back with him. They're not going to WANT to tell you about the extraction process because it might be... bad for business!

I have serious reservations about ViSalus and their pat answers for everything. I very much agree... this is about money. And certain people are making at LOT of it. You'd better make sure that if you're involved with this company, that they aren't making it at YOUR expense and at the expense of YOUR health. There is already a mountain of information about soy that anyone (well, anyone who doesn't have an AGENDA) would admit that something is very, very wrong with this "health" food. It's only healthy for the pocketbooks of certain people.

I did my research as did my cancer doctor. I started the product because of severe weight gain from my treatments! The gain affected my liver to which fat was inside not surrounding like most people! In 30 days all the fatwas gone from inside my liver I was thrilled and my doctor stunned! The product is safe for all to consume. I've lost 84.6 lbs in my journey. My kids father suffered from 2 brain rumors 4 surgeries and his diabetic doctor approved the shakes as of Tuesday November 27th his doctor took him off his diabetic medication, cholesterol medication & high blood pressure medication. He with minimal exercise lost 46lbs! The goal of the company is to end obesity! Starting with replacing 1-2 meals a day, eating 3 snacks a day and a healthy dinner. You learn how to cook & eat healthy. My family is healthier because I started the product and then they joined me!!!!

My question is, "Why do you care"

Let's assume what your friend is selling is high quality and healthy. Then good. I can still get the same quality much cheaper from other sources, so why bother?

Let's assumed what your friend is selling is crap. If she's making money, do you really think that your "paleo" perspective is going to changer her mind? so why bother?

Part of Paleo is keeping stress to a minimum. This is just added stress. Focus on your health and your family's health. As long as no one is preventing you from making your own decisions, probably not a good idea to step on other's toes. You did your part by raising the issue, now it's up to her.

Dr. Michael Seidman is an ENT doctor. I doubt he is qualified in the area of nutrition.

I hate to use a vegan guru to discuss the dangers of soy isolate but I think Mcdougall has some pretty convincing arguments, and he might be a little easier to process than paleo gurus for this particular subject.

Oh shut up, you guys have no clue. Its funny how so many people make comments like that until they join the company. I am sure your fat sitting at McDonalds driveway or eating poorly. The LAST thing you have to worry about is a SHAKE let alone SOY.
