EAS soy protein

Hello,
I have been using EAS soy protein for a few weeks and I mix my Miralax in it. Yesterday at the clinic I told the Doctor I was using a protein supplement, but couldn't remember the name, she told me be aware that some of these supplements can cause kidney problems. Looking over the net I haven't found any warning on this product. Your comments welcomed

I have only read about a rare kidney problem with excess creatine supplements. Body builders typically consume huge amounts of creatine and/or whey/soy protein when enhancing muscle building. In a regular person, the protein you consume is much much less.

The amount you use for food intake, should not be a problem, unless you already have poor clearance?

There is little evidence to link high protein intakes (up to 2 g·kg–1·d–1) to increased risk for impaired kidney function in healthy, physically active men and women (75-77). However, there is evidence that a higher protein intake may facilitate a greater decline in renal function in those with modestly impaired renal function (75). In patient populations, high-protein diets may lead to glomerular hyperfiltration and hyperemia, acceleration of chronic kidney disease and various associated metabolic alterations (77). In higher-risk groups, including those with existing renal disease, high-protein diets should be avoided (78). The initial onset and progression of chronic kidney disease are often symptomless. Consequently, initial screening (serum creatinine and urinary dipstick for proteinuria) and subsequent monitoring of renal function and creatinine clearance may also be prudent in older individuals before commencing a higher-protein diet as both lean body mass and renal function decline with age (77).

You know when doctors or PAs say things that seem to not be correct, we should all pin them down and say....prove it.

Males especially need protein. Testosterone is carried in the blood by carrier proteins, which decline with poor protein food intake.

I would like to add....

1) too much soy as protein may impact the thyroid negatively. This is rather controversial, but may happen.

2) I hope you have other sources of protein in your diet too.
Methionine is less prevalent in soy than in animal sources.

3) this might be why your cholesterol went down. Soy can lower it.
