Glycine to the rescue
Although it is one of the most overlooked amino acids, glycine actually has a lot of properties that can save you from diseases like diabetes, scaropenia, and stroke, so make sure to monitor your intake. The best source of glycine is found in the chops of meat that are usually thrown away, such as bones and tough connective tissues, and gelatin, the first food in this list, is the closest you can get to tapping high amounts of glycine.
