You may have heard that bone broth is rich in minerals like calcium but is it really? Turns out the answer is no. Like many people, I always naturally assumed that phone broth was rich in minerals, because, ahem, it comes from bones￼. I had noticed at one point that there was no calcium in any of the bone broth that I had ever purchased, which I thought was odd. However, I eat enough other calcium-containing products￼, so I didn’t dwell on it.￼ For whatever reason, today I was curious to find out why. I came across this article, which I don’t think actually gave me the answer to my initial question. However, it did have some very interesting information about the benefits of eating the protein in bone broth, because the amino acid composition balances the excessive amount of methionine in the American diet.￼￼
Here’s what the research shows:

Modern American diets tend to have an imbalanced amino acid intake. The reliance on muscle meats almost exclusively, instead of engaging in “nose-to-tail” eating of the animals, results in an overabundance of some amino acids and a very little of others. This imbalance appears to have significant consequences for our health such as fertility and lifespan.
Also, bones in animals and humans are only partially made up of minerals but a large percentage is collagen which is built from proteins. The two main proteins in collagen are glycine and proline, and a fair amount of glutamic acid which gives the foods made from bones their rich and savory flavor, as explained extensively in the cookbook Broth and Stock.
This is in stark contrast to muscle meat, whose primary amino acid is methionine. Methionine can deplete your body’s glycine stores, among other problems it can contribute to when consumed in excess. And make no mistake, most modern American diets have an excess of methionine because of the over reliance on animal muscle meats and disregard and dislike for the other parts of the animal.
