Yes, bananas can really help in appeasing anger and mood swings. As well as almonds, cheese and orange juice. Cheese is a rich source of protein, tryptophan, essential amino acids and carbohydrates. Thus, the cheese helps improve mood and relieve irritability and moodiness. Also a glass of sweet oranges can also be a shock to anger. Mix sugar with lemon juice to make the limits of patience more flexible than they should, so useful for the control of mood and other negative emotions. Hope these helps.
