I know the use of soy can be a heavily debated topic. I only ask about it because I have recently discovered soy crisps. They are a nice alternative snack and they contain a decent amount of protein. The most protein I get from them would be about 15 grams in a sitting a few times a week. Does anyone see any problem with this?

this makes sense, I'd imagine it's a low percent of your overall caloric intake (and protein intake). But if you get weepy I'd probably cut back :clown:

Really tough to say- isoflavone concentration in soy proteins is really variable. Apparently a lot of soy protein concentrates are relatively low in isoflavones.. came across an interesting chart here:

(to cite: (This information was distributed as part of a presentation at the American Dietetic Association 80th Annual Meeting and Exhibition, held October 27-30, 1997, in Boston, Massachusetts, by James W. Anderson, M.D. Professor of Medicine and Clinical Nutrition University of Kentucky, Lexington, KY. Phone 606-281-4954; fax 606-233-3832, e-mail: jwandersmd@aol.com)

Food, then isoflavone mg/gram of protein.

Mature soybeans, uncooked 5.1
Roasted soybeans 5.5
Soy flour 5.5
Textured soy protein, dry 5.2
Green soybeans,uncooked 3.3
Soy milk 2
Tempeh, uncooked 3.1
Tofu, uncooked 2.1
Soy isolate, dry 2.2
Soy concentrate, dry 0.3


I don't have a lot of data on what is considered a therapeutically active concentration of isoflavones, though trials on post-menopausal women use anywhere from 40 to 100mg/day. Which, roughly, equates to 1-2mg/kg.

Assuming these crisps contain soy isolate, I'd opt to stay at half the low range of that dosage, so 0.5mg/kg... or in my case, anything less than ~50 mg of isoflavones a day is probably safe.. or total soy intake of 25 grams of isolate.

And that would be every day.

Interesting post Vinnie, I have wondered the same thing.......I can get soy protein crisps for $2.70 here which taste awesome and have 18 grams P.

I have nothing to add really other than I prob would not have soy every day just to be sure.

I think Soy products such as soy burgers, soymilk, and soy cheese are much more popular and available today.

:confused:

i used to snack on soy nuts alot some years ago
anyone try them? as long as they're salted or added spice flavorings they're not bad. like crunchy hard little peanuts but kinda bland no peanut taste.

didn't really notice any negs or positives from eating them.

ALN's novus bars use soy protein. I seem to remember them using the proprietary ALN whey/egg/casein blend when they first started but I could be wrong. Regardless I bought 3 boxes of these novus bars, all containing 36g of soy isolate per bar and I am eating at least 1 per day. I'll let you know when I start to cry uncontrollably and desire to see chick flicks.

for reference I'm 270 lbs and about 15% body fat (guessimate, based off looking in the mirror [flat stomach, jiggly 6 pack])

Humans shouldn't consume soy, ever. Grains either. Soybean oil is in just about every processed "food" item. Avoid them. Eat meat and vegetables. Then more meat and vegetables. Much better and tastier food choices anyway, so why choose soy?

As much as I agree with the overall sentiment here, I don't know if it's quite an absolute. We're quite adaptable to numerous types of food. Grains shouldn't be a mainstay by any means, and soy is entirely too prevalent in our diet (considering it IS detrimental to our endocrine systems), but I think there's a bit more leeway than "zero".
