Emotions, doshas, nutrition, and 6 tastes as per Ayurveda…..

Each of the 6 tastes produces or enhances a certain emotion when eaten. Thus, emotional disorders may be balanced by eating and avoid foods, according to the taste.

Taste	Emotions	Deranges
Sweet	Desire	Kapha
Sour	Envy	Pitta
Salty	Greed	Kapha
Pungent	Anger	Pitta
Bitter	Grief	Vayu
Astringent	Fear	Vayu

Vayu is balancing by supplementing with moist tastes, sweet, sour, and salty (balancing dryness), and some warm tastes as well. Pitta is balanced by using sweet (moist), bitter and astringent (cooling) tastes. This helps counter heat-related illness (e.g. rashes, infection, and anger impatience). Kapha disease is removed by using sour and pungent tastes (i.e. they heat and burn up water). Bitter taste also reduces Kapha by causing a drying action. 

Sweet: Generally food is sweet in taste, neutral in energy, and sweet in its post-digestive effect. It decreases Vayu and Pitta and increases Kapha. It nourishes and maintains humor, dhatus, and malas (waste). 

Sour: An example of sour taste includes sour fruits, tomatoes, pickles, and vegetables. All tissues are nourished by a sour taste, except reproductive tissues (of the sour taste only yogurt nourishes all tissues).

Pungent: Spices and spicy vegetables do not offer much nutrition, but they stimulate digestion.

Bitter: Vegetables offer little nutrition. They are useful in clearing and cleansing digestive organs, and in aiding digestion, especially if taken before meals (for pitta and Kapha doshas).  

Astringent: This is mainly a secondary taste. Astringent food like green vegetables and unripe apples, provide minerals but do not build tissues. 

Energy: Most foods are neutral in heating and cooling effects. To apply hot or cold therapeutics, appropriate spices and foods are eaten cooked or raw.

Heavy/Light: Most foods tend to be heavy, though, many light foods also exist. Spices can make food lighter. Oils can make them heavier. Foods are also dry or moist. Dryness can be increased by eating dry foods or toast or made moister by frying food or adding liquid.
