Keep pistachios in sight for the sake of your kid’s eyes. The green nut is bursting with lutein and zeaxanthin, two sight-saving relatives of beta-carotene. One ounce of pistachios boasts 342 micrograms whereas other nuts have 8 micrograms or less. Other foods with lutein and zeaxanthin include leafy greens, peas, winter squash including pumpkin, corn and Brussels sprouts.
