Difference between soy and whey protein?

Post by nazzisoroush »

I bought soy protein Ultra XT... but, in this website, only whey protein has been mentioned, so is whey better than soy?

nutitional info for the one I have is
cals: 120
fat: 0
total carbs: 5 gram
dieterty fiber: 5 g
Protein: 25 g

I mix it usually with milk and some vanilla yogurt after workout.. then have dinner shortly after.

How can I maximize the benefits I get from this for fat loss, while building osme muscle?

whey over any other Post workout simply because it is absorbed faster ... rest of the day it should be from real food.

And for men soy protein may be "harmful" for test level (due to zinc absorption trouble I believe)

Not necessarily harmful. The Genistein, is similar to Oestrogen, and can bind to receptors, so it can block excess Oestrogen activity, and for women this could help protect agaisnt Breast Cancer, but alternatively so it could in men.

I think it also affects Oestrogen in men, by stopping it contributing to hairloss issues, if I remembered correctly.

test levles can also be helpd by things like Vitamin E, possibly A, also C, and yes Zinc, but reality is, men have healthy levels between 350, and 1,000 mg's per litre of blood, so unless you fall below 350, which could increase Heart attack risks, it shouldn't be a problem in humble opinion.

Obviously if the person is concerned, they could get a Testosterone check done perhaps, and if they had a level like say 700mg's, then clearly if Soy does negatively interact with Zinc, any possible cons, as opposed to pros, would be negligable.

If the level of the person was 380mg's, then perhaps cause for concern, but then the person could increase Zinc, and consumption of things like Vit A, E and C. Zinc is rife in many foods, and in most if not all cases mirrors Iron.

Not to say it's connected to Iron particularly, or helps it, or Iron helping Zinc, as I'm pretty sure they don't compliment each other or compete, but those could be ways to stimulate more Test production.

Frankly, in light of such things, I would say, if there is a Soy / Zinc competition issue, (I haven't heard of such a thing before), I would think in most cases it wouldn't matter, and in other cases, dietary changes could increase Test, to levels where it wouldn't matter.

To answer the first question, Soy I think is okay, but Whey is better.
