    Centenarian Blood Test Analysis (n=1,754)

  5. I'm not worried about oxalate causing kidney stones, but bone density. Oxalate binds calcium 1:1, so with a higher intake of oxalate than calcium, even on a calcium-sufficient diet (> RDA), I'd bet that there could be issues related to bone density. I haven't come across any published literature for that, unfortunately. But also, most people don't eat 180g of spinach/d, so it's unlikely that data exists. I already get a sufficient amount of nitrates from ~210g of daily beets, and have replaced the spinach with collards, which are low in oxalates yet still high in Vitamin K. We'll see if/how the switch affects my blood biomarkers on upcoming tests.
  6. My average calcium intake is 1200 mg/d, but I've averaged as high as 2000 mg of oxalate/d. When considering that calcium binds 1:1 to oxalate, I wonder how much calcium I would actually absorb with that much oxalate. I'm not worried about kidney stones, but in contrast, bone density. I've since replaced my 5-6 oz of daily spinach with collards, which are low in oxalates.
  7. Unfortunately, Cronometer doesn't include methionine intake for all foods-for example it isn't listed for the brand of sardines or cacao that I commonly eat. That's why I went with total protein instead. I average 85g of fiber/d, so I eat lots of plants and correspondingly, plant protein. If I calculated it, at least 70% of my protein intake is from plants, with the rest from animal sources (fish, yogurt, some parmesan cheese). I use WHOOP, not Garmin... Cronometer recently added oxalate to its measures. It's under "Settings-->Profile and Targets", and then at the bottom of the page you can make oxalate visible.
  8. Do you mean methionine from plants vs animal products?
