On the Allocation of Tastes and Scents

🧠 In-Depth Understanding

Core Concepts 💡

• Five Tastes Correspond to Five Elements: Sour belongs to Wood🌿, Bitter to Fire🔥, Sweet to Earth⛰, Pungent to Metal⚔️, Salty to Water🌊.
• Five Scents Correspond to Seasons: Spring - Shan (羊羶, muttony), Summer - Jiao (焦, scorched), Autumn - Xing (腥, raw fishy), Winter - Xiu (朽, rotten), Late Summer - Xiang (香, aromatic).
• Diet Follows the Four Seasons: Warm and dispersing foods are suitable in spring and summer; cool and consolidating foods are suitable in autumn and winter to harmonize the body's Yin and Yang.
• Five Zang Organs and Five Tastes: The five tastes enter the five organs. Excessive consumption harms, while moderate consumption nourishes, forming a dietary therapy system of "tonify-drain-restrict."

Modern Interpretation 🌟

1. Essence of Five Tastes: Essentially an ancient, rudimentary classification of food chemical components—sour often contains organic acids (e.g., lemon), bitter often contains alkaloids (e.g., coffee), pungent contains volatile oils (e.g., gingerol), salty contains minerals (e.g., sodium chloride), sweet often contains carbohydrates (e.g., glucose).
2. Science of Scents: The so-called "Five Scents" are actually volatile odor molecules: Spring Shan (short-chain fatty acids), Summer Jiao (pyrazines from roasting), Autumn Xing (amines causing fishiness), Winter Xiu (thiols from decay), Late Summer Xiang (esters creating fragrance).
3. Spatio-Temporal Medical View: Advocates adjusting diet with the seasons—Spring: Wheat🌾 (carbs for energy), Summer: Legumes🥜 (protein to clear heat), Autumn: Hemp🌰 (oils to moisten dryness), Winter: Millet🍚 (high calories against cold). This is essentially nutritional adaptation to natural cycles.
4. Organ Balance: "Liver ailments restrict pungent" because pungent's dispersing nature consumes Liver Yin; "Kidney ailments restrict sweet" because sweet's cloying nature increases Dampness in the Kidney—essentially controlling specific nutrient intake to reduce metabolic burden.

Practical Value ⚡

• Seasonal Recipe Design:
  • Spring: Wheat products + Mutton (warm tonification, raising Yang)
  • Summer: Legumes + Chicken (clear heat, boost Qi)
  • Autumn: Sesame + Dog meat (moisten dryness, tonify Metal) (Note: Modern substitutes advised)
  • Winter: Millet + Pork (nourish Yin, store essence)
• Subhealth Regulation:
  • Insomnia, vivid dreams (Excessive Heart Fire) → Reduce salty foods (e.g., less salt), increase bitter foods (e.g., bitter melon)
  • Indigestion (Spleen Deficiency) → Avoid sour foods (e.g., vinegar), increase sweet foods (e.g., millet congee)
• Dietary Taboos for Diseases (Some still have modern medical basis):
  • Fracture recovery period → Limit salt (Salty enters blood,不利于愈合 not conducive to healing)
  • Chronic cough → Avoid pungent-spicy (Pungent disperses Qi, aggravates airway irritation)

Philosophical Reflection 🤔

The ancients incorporated taste and smell into a cosmic schema, essentially constructing a "philosophy that can be tasted"—perceiving the flow of the Five Elements through the tongue, making dietary practice a microcosm of universal rhythms. This "metaphysics of taste" reflects both the agrarian civilization's submission to natural rhythms and implies an ecological holistic view of the "human body as a microcosm."

Modern Research

• Japanese scholar Kuriyama Shigehisa's The Expressiveness of the Body compares ancient Greek "humor theory" with TCM's "five tastes theory."
• China Academy of Chinese Medical Sciences' Modern Pharmacological Research on the Five Tastes Theory confirms:
  • Sour herbs often contain tannins (e.g., Schisandra) with astringent effects.
  • Bitter herbs often contain alkaloids (e.g., Coptis) with anti-inflammatory properties.
  • Sweet herbs often contain polysaccharides (e.g., Astragalus) enhancing immunity.
  • Pungent herbs often contain volatile oils (e.g., Cinnamon) promoting circulation.
  • Salty herbs often contain minerals (e.g., Oyster shell) softening nodules.
