Join Zain Saraswati Jamal, mind, body, and spirit coach, as she walks the aisles of her local market. For the healthiest options, stick to the perimeter of stores for fresh, real, and unprocessed whole foods. While you’re picking the best foods, remember to eat the rainbow of colors available in the fruits and vegetables you find there. The richer the colors, the more antioxidants and immune boosting nutrients you get.
