Supermarkets are not renowned for their healthy practices when it comes to fruit and vegetables but it does seem that they might be doing something right. Spinach, and other produce, are kept in supermarkets at cool temperatures under fluorescent lights 24 hours a day. To test what this did to the spinach leaves researchers kept fresh spinach leaves under continuous light or darkness of between three and nine days. Spinach kept under lights for as little as three days had significantly higher levels of vitamins C, E, K, folate, lutein, and zeaxanthin. Leaves stored in darkness lost nutrients so photosynthesis continues after picking as long as there is air, moisture in the leaves and light. Harvesting from your garden is still the best option but when it comes to storage spinach is just like the rest of us, it doesnâ€™t like to be kept in the dark.Meanwhile if you visit Meijer Ad that contains mostly likewise discounts with Winn Dixie Ad you surely have a range like ALDI Ad.
