How Much Lead Leaches Into Organic Chicken Bone Broth?

I had always assumed bone broth was nutritious. Guess not. Read this post.

From the post:

most of the lead ends up in the birds’ skeletons, which raises the question: What happens when you try to make chicken soup?

There may be an upswing in people boiling bones, which is “encouraged by advocates of the paleolithic (or ‘paleo’) diet,” but the problem is that lead is a neurotoxin—but not just a neurotoxin. Lead also adversely affects the bone marrow, digestive tract, kidneys, circulatory system, hormones, and reproduction. Symptoms of too much lead exposure include impaired cognition, anemia, abdominal pain, kidney problems, high blood pressure, miscarriages, memory problems, constipation, impotence, depression, poor concentration, and more. What’s more, we know from human studies that lead is sequestered in bones. When there is a lot of bone turnover, for example, during menopause or pregnancy, lead levels in the blood can go up. This bump can be minimized during pregnancy by getting enough calcium and lowering sodium intake, though. When astronauts lose bone in space, the lead is released into their bloodstream. Ironically, since they’re no longer being exposed to all the lead on Earth, their overall lead levels may go down. Bones are so good at sucking up lead, they can be sprinkled on firing ranges to prevent lead from leeching further into the environment.

Researchers concerned that the boiling of farm animals’ bones might release lead into the broth made three types of organic chicken broth—one using the bones, a second using meat without the bones, and a third using the skin and cartilage without the bones. All three of the broths exceeded the maximum allowable dose level for lead—even the one made without bones. Surprisingly, the skin and cartilage broth was the worst, exceeding the safety level per one-cup serving by about 475 percent.
