(Carakasaṁhitā - Sūtrasthānam – 27.348)

प्राणाः प्राणभृतामन्नमन्नं लोकोऽभिधावति।

वर्णः प्रसादः सौस्वर्यं जीवितं प्रतिभासुखम्॥

तुष्टिः पुष्टिर्बलं मेधा सर्वमन्ने प्रतिष्ठितम्।

लौकिकं कर्म यद्वृत्तौ स्वर्गतौ यच्च वैदिकम्॥

कर्मापवर्गे यच्चोक्तं तच्चाप्यन्ने प्रतिष्ठितम्।

(चरकसंहिता – सूत्रस्थानम् – २७.३४९-३५१)

The source of life for all living beings is food and all living beings are food and all the world seeks food. Complexion, clarity, good voice, long life, understanding, happiness, satisfaction, growth, strength and intelligence are all established in food. Whatever is beneficial for worldly happiness, whatever pertains to the vedic sacrifices leading to heaven and whatever actions lead to spiritual salvation are said to be established through food.
