But here are some foods that are rich in Phosphorous. You can see if you are getting these in your diet:
Whole Wheat and Bran
Cottage & cheddar Cheese
Corn & Broccoli
Chicken & Turkey
Beans & Nuts
You could also take a mineral supplement, like Supreme Fulvic and Humic Complex or Fulvic Acid. Both great products.
A serious phosphorous deficiency would start to effect one's bones and teeth.
Many thanks for a prompt and complete response! Normally, I wouldn't concern myself with fractions of a per cent out of range. Especially since it's a one-time measurement and doesn't necessarily give a full picture.
The primary reason I thought I should be more mindful of the result is because I do eat enough high-quality foods that should contain adequate phosphate/phosphorus supplies.
The second reason is that my GP had me supplementing with 2000 IU of Vitamin D3 to "correct" a barely insufficient serum level of 25 ng/dL. Within a few short months, I managed to get that up to 38 ng/dL.
I do know that Vitamin D plays an important role in calcium and phosphorus regulation (and a few other attributes as well.)
My position is that when you push one side of something, it gives elsewhere. So, I wondered if the Vitamin D3 intake offset something somewhere else. Unlikely, but possible. As my GP said, "The body is amazingly adept at maintaining homeostasis - even under extreme conditions." So, maybe my body "prefers" a lower Vitamin D3 status? It's not that low - even with these new guidelines. I'm as Northern European as they come, so I've perhaps evolved with my ancestry to function quite well with suboptimal Vitamin D3, per today's standards.
I tend to avoid "monkeying" with the body by taking supplements. But I'm not completely averse to the idea -- when there is clear evidence in support of it.
We'll see how things look in another 3 to 6 months. I appreciate the thoroughness and thoughtfulness of your response, jenj770!
