Too much phosphorus is hard on the left kidney (not the right, if you have both) and can lead to "osteoporosis, arthritis, gout, dental problems (loose teeth, caries), skin eruptions, lowered WBC, higher risk for several cancers, kidney stones."
From this site
Phosphorus, when high in ratio to calcium, is well established as being a contributing factor with bone loss / osteoporosis, and many articles have been published on the dangers of consuming too many soft drinks because of their high phosphorus content. A similar message is being preached regarding protein, supposedly having the same effect on calcium loss. Forgetting about the heated hype (agenda) for a moment, any viewpoint can be correct for specific individuals, but it cannot be applied for the masses as there are as many people who exhibit below- normal protein / phosphates, as are those who are above-normal, so only individual assessments are valid. Osteoporosis and arthritic conditions can develop with high and low protein / phosphate levels, which subsequently rules out "one-fits-all"- types of recommendations.
My WAG would be that for someone with a strong, healthy, efficient left kidney, the kidney can handle the stress of extra phosphorus in the diet, and the body simply excretes it as nature intended. If the kidney isn't so strong or efficient, bad things happen. If you have any of the medical conditions listed above, perhaps those would be warning signs that your own particular body isn't handling extra phosphorus so well.
So I guess the answer is "maybe, maybe not, check with your doctor."
