LOS ANGELES, Nov. 6 (UPI) -- A U.S. health and wellness expert says an easy way to boost immunity is to eat more fruits and vegetables in different colors.
Amy Hendel says says a study published in the Phytonutrient Report found eight in 10 Americans are missing out on the health benefits of a diet rich in colorful fruits and veggies -- resulting in a phytonutrient gap.
