Bhagavad Gita 17.8 — Sattvic food
आयुःसत्त्वबलारोग्यसुखप्रीतिविवर्धनाः। रस्याः स्निग्धाः स्थिरा हृद्या आहाराः सात्त्विकप्रियाः ॥
āyuḥsattvabalārogyasukhaprītivivardhanāḥ | rasyāḥ snigdhāḥ sthirā hṛdyā āhārāḥ sāttvikapriyāḥ ||
Meaning
Food that increases life, purity, strength, health, joy and cheerfulness — juicy, smooth, nourishing and pleasing — is dear to sattvic people.
