Yogurt
Yogurt contains a lot of lysine. While all most yogurts are rich in lysine, low-fat yogurts without any embellishments are particularly high in this essential amino acid. It also has a high lysine to arginine ratio. This is good for you if your diet requires cutting the amount of arginine you consume. A 245-gram serving of yogurt should give you around 1,150 milligrams [1] of lysine.
Tempeh
Tempeh is made from partially-cooked fermented soybeans mixed with a fungus, typically Rhizopus oligosporus. It is a popular Asian food many vegans trying to increase their lysine intake lean toward. There are many ways to consume tempeh. You can include it in stews and curries or consume it alone toasted. A cup of tempeh contains around 1,510 milligrams [2] of lysine. Unlike yogurt, tempeh has more arginine than lysine. You should consider this if you need to reduce your arginine intake.
