What is the Plant-Based Diet? A Simple Overview
Picture your plate as a thriving garden, bursting with colors and vitality that nurture your body's defenses from the ground up. The Plant-Based Diet emphasizes whole foods derived from plants—fruits, vegetables, grains, legumes, nuts, and seeds—while minimizing or excluding animal products. It's more than meals; it's a compassionate choice that aligns with sustainability and health, drawing from global traditions like Mediterranean and Asian cuisines. For those facing cancer, it offers a gentle, fiber-rich foundation that empowers cellular repair and inflammation control.
