Symbolic reading

The nourishment you are taking in is actually corrosive. This suggests that something you are accepting—an idea, a relationship, or a situation—is causing you emotional distress or bitterness.

Practical reading

Be cautious about accepting input from certain sources. If you are swallowing a difficult situation, pause and evaluate its true cost.

Psychology explanation

Sourness is a visceral reaction to something that is 'off.' Psychologically, it indicates that your subconscious detects toxicity in a situation that your conscious mind might be trying to rationalize as beneficial.
