Understand the serotonin/food myths. Unfortunately, there are a lot of myths surrounding food and increased levels of serotonin. These myths include: Foods rich in tryptophan automatically boost serotonin. This is false. Most foods that contain tryptophan, an amino acid, compete with other amino acids to be absorbed by the body's transport system. Eating a lot of turkey, which is rich in tryptophan, will not automatically give you more serotonin. Eating a lot of banana will automatically boost serotonin. Bananas do contain serotonin. That serotonin, however, is unable to cross the blood-brain barrier and be absorbed by humans.
Best Answer: On the right side of your waist you have your liver (4) and within this area you also have your gallbladder (5). See the image on the source page.
It may seem odd that you would only develop pain on one side of your body after eating, but if you have gallstones, you may only feel pain on your right side. Gallstones are clusters of deposits that form in your gallbladder that can cause severe pain in your right side if a stone becomes lodged in the duct. If you develop pain in your right side, you need to make an appointment with your doctor or a general surgeon to determine whether or not you have gallstones.
