There are numerous causes of sacrum, or sacroiliac, joint pain. According to the Sports Injury Clinic website, the sacroiliac, or SI joints, are located near the tailbone and connect the hip bones with the sacrum, which is a large, triangular bone situated at the base of the spine.
The Mediterranean diet is one such diet. It emphasizes grains, but also emphasizes fruits, vegetables, cheese, yoghurt, and fish, all foods high in lysine and low in arginine. This is generally attributed to omega-3 fatty acids in fish. Fish have a high lysine to arginine ratio. Dairy products also have a high lysine to arginine ratio.
Arginine foods have many health benefits which include improving circulation to help erectile dysfunction and sperm count as well as speeding up the time needed to recovery from injury. If you want to naturally raise levels of this amino acid, foods that are high in protein are a good choice.
