Bhagavad Gita · Chapter 17: The Three Kinds of Faith

Bhagavad Gita 17.8

āyuḥsattvabalārogyasukhaprītivivardhanāḥ | rasyāḥ snigdhāḥ sthirā hṛdyā āhārāḥ sāttvikapriyāḥ ||

Foods that increase life, vitality, strength, health, happiness, and satisfaction, and that are tasty, smooth, nourishing, and pleasing, are dear to people of clarity.

Modern context

Sattvic food increases life, energy, strength, health, happiness and contentment. It is tasty, smooth, nourishing and pleasing. Notice that it is meant to be enjoyable. The Gita does not recommend joyless eating. Good food, fresh and wholesome, prepared with care, nourishes both body and mind. A great deal of modern nutrition advice agrees.
