To improve anxiety symptoms, make sure to add vitamin B foods, magnesium rich foods, foods high in calcium and omega-3 foods to your diet too. Such as:  wild-caught fish 

Wild-caught fish, especially the more oily types such as salmon, mackerel, trout, sardines, and tuna, are great choices to help fight depression. Why? Because they are rich sources of omega-3 fats.

Including fatty fish like wild Alaskan salmon, contain omega-3 fatty acids. A study completed on medical students in 2011 was one of the first to show that omega-3s may help reduce anxiety.  Prior to the study, omega-3 fatty acids had been linked to improving depression only.

researchers analyzed 26 previously published studies that examined the association between fish consumption and the risk of depression, and found that people who consumed the most fish were less likely to have depression symptoms.
