There is an amino acid called glycine some may know of because it has been theorized to be of some benefit for human sleep. In fact, there are some health supplements combining glycine with other molecules or nutrients for that purpose. How much truth there is to the better sleep claim is debatable; the sleep benefit actually might be from the placebo effect. There are some other ideas about glycine’s benefits related to heart disease prevention and joint and skin support. For the people who know what glycine is, they may have also heard of bone broth, but this food has some issues, according to Conscious Health Institute, which states that “There is also a potential danger in getting nutrients from bones as opposed to plants. Animals concentrate heavy metals, which are toxic metals such as lead and mercury, in their bones. Some studies have found high levels of these metals in bone broth, that would lead to health problems if regularly consumed, while others have found very low and safe levels.” Animal foods are some of the worst foods for climate change, such as beef, pork, lamb, and farmed shrimp. The thing is, there are dozens of food sources of glycine that are not really bad for climate change and don’t have contamination issues. They are plants, and yet many online sources state it is animal foods to look at for getting glycine. They are all incorrect because there is a huge number of plants that also have glycine, so eating animal foods is not necessary. Here is a list of 75 plant foods containing glycine.
