    Eat The Rainbow Diet

    The "Eat the Rainbow" diet emphasizes a diverse, plant-focused approach to nutrition. By consuming a variety of colorful fruits and vegetables—from lycopene-rich reds to anthocyanin-packed purples—you naturally absorb essential phytonutrients. This simple habit boosts immunity, supports heart and brain health, and reduces inflammation for long-term chronic disease prevention.
