Question:
Can someone tell me the difference between Soy and Whey protein?

I am looking into the soy protein products to supplement my Baritec and Nectar protein supplements. I was looking for coffee that I could make into an ice coffee for warmer weather. I found Revival Soy Coffee that claims soy will help with menopausal issues such as dryness. I am realy confused at the difference between soy and whey and if it matters what we use. Thanks in advance for any answers!    — cindy O. (posted on April 25, 2003)

Soy is plant based and whey is milk based. I personally use whey protein because I'm on Synthroid - the dietician/nutritionist said that people on synthroid should not use soy based protein (not sure why).

I use soy to cook with. Otherwise I use whey. If you are using soy in additon to whey, I don't see any problem, but whey based products should be the foundation of any protein supplements you use.

I would post the BV list, but I think it would just come out one long paragraph. I have yet to figure out how to make columns or space things here. LOL! (only 5 yrs here). Blended whey is #1 in bioavailability, soy is about #10. Whey is smoother, if flavored has less sugar than soy products. Soy tends to be gritty. While there are plain ones with 0g sugar, most of the flavored ones contain too much, even when mixed with water. There are literally hundreds of whey products on the market. You should be able to match something to your tongue with a little trial & error. Personally, I see no need for anything that is not chocolate, but there are misguided people who think otherwise. Crazy, huh? Mine will shake up in about 4 oz of water if I choose. My fave is made with 8 oz water+ ice, hand blender. Mmmmm. 32g protein, 0g sugar. If you want the benefits of soy, you can always add a tiny bit to your whey shake & get the benefit of both.

Soy tastes a helluva lot better than whey, without a nasty aftertaste!!!

I, too, researched sources of soy protein to up my recommended amount of 60 g of protein per day. I have been using Revival Soy products for about 6 months and they are GREAT! (20+ g protein per shake) There are 4 flavors of shakes, protein bars, and know they sell coffee, pasta, and other snacks. I drink one each morning for breakfast...really fills me up. (No, I don't work for them). It's easy enough (www.soy.com) Everything I've tried is very tasty.

Karen is right - if you have any thyroid problems, avoid soy. Soy protein binds with thyroid hormone - not a good thing if you already have problems keeping your thyoid levels up so you feel like part of the human race! Same for me - on Levoxyl instead of Synthroid (allergic to it!).

According to my nutritionist, we absorb whey easier/better.
