Wyndahoi saidI would be very wary of rice protein. Rice pulls up more heavy metals out of the soil than any other plant. If you have a little bit of rice once a month it's not a big deal. If you're consuming multiple servings of rice protein though you're going to ingest a lot of arsenic over time.
Do all milk products cause this problem for you? Or just whey? Have you tried casein powder? Kefir is a very good source of protein- 44 gm/quart. And it's 99% lactose free since its fermented.
A lot of foods people warn you away from like soy and dairy and very easy to digest when they're fermented into yogurt/kefir and tempeh respectively.
If you're worried about possible arsenic in rice protein powders (which mind you is naturally occurring in numerous plants including apples) then you should be worried about all the bovine growth hormone, anti-biotics, and genetically engineered soy fed to the cows your whey protein is coming from. Come on now...
That's what I'm thinking too. It's much easier to detox your body of heavy metals than all that shit they pump into cows these days. Plus you just know the shit they use for the whey protein is probably the lowest quality imaginable.
Actually, your thinking is wrong. First of all, there is no proof that hormones or other "shit they pump into cows these days" is actually bad for you. Which doesn't mean it's safe, just that there is no proof. However, there is LOTS of evidence of how bad heavy metals are for you. And no, it is NOT easy to remove them. There are some chelation therapies, but they have limited efficacy.
I want to reiterate that I am not saying that modern meat and dairy industry is good and wholesome. I buy grass fed whey for that reason and limit my meat intake.
However, rice and its derivatives need to be eaten with caution. Amounts of heavy metals present will vary depending on where it was grown. Bangladesh, for instance, has very high levels of arsenic in its groundwater. Eaten occasionally, you won't get enough heavy metals to be concerned. But frequent use of rice protein is probably not a good idea.
