A pickle a day may keep anxiety away. Sour tastes stimulate the Liver, the organ that is most sensitive to and energetically processes stress, tension, and emotional turmoil. Most fermented foods are salty as well – salt is the taste associated with Kidney function, which in turn energetically regulates fear. Because social anxiety is often fear-based, balancing and strengthening the Kidney with salted foods can also help modulate anxious feelings.
