It elevates one's mood. Glycine, an amino acid found in gelatin, is known as a "inhibitory neurotransmitter." That is, it has some of the same properties as anti-anxiety and anti-depressant medications, but without the negative effects. Gelatin products such as jello are made from collagen proteins that have been denatured by heat. The heating breaks down some of the collagen into glycine which can be used by the body for energy. Gelatin may also help reduce anxiety by acting as a natural diuretic. This means that it helps remove toxins from the body through your urine. Toxins include chemicals that build up in your body due to poor diet or excessive alcohol consumption. Removing these chemicals through your urine will help relieve stress and give you a clear mind. People who suffer from anxiety might be more likely to consume foods that raise their level of cortisol. Cortisol is a hormone that plays a role in regulating stress. Too much cortisol can lead to anxiety. Eating foods that raise or lower your level of cortisol will not only affect your level of anxiety, but also your ability to deal with stressful situations. Certain foods contain substances that bind to cortisol receptors in your brain. When this happens, you do not feel anxious anymore because there is no need for more cortisol. These foods include clams, oysters, mussels, scallops, and shrimp.
