Foods that increase life, inner clarity, strength, health, happiness and contentment, that are flavorful, smooth, lasting and pleasing to the heart, are dear to those of sattvic nature.
Explanation
Krishna is explaining how the three qualities of nature (gunas) shape a person's tastes, starting with food. Sattva (clarity, balance) draws a person to nourishing food that supports a long, healthy and cheerful life. The 'smooth' and 'lasting' qualities are often read as oily, wholesome food that sustains the body over time; the verse describes preferences rather than giving a fixed menu.
