Prepare your salad the day before you eat it
Jo Robinson, author of the book Eating on The Wild Side, which reviewed thousands of health studies, explains that tearing romaine and iceberg lettuce the day before will quadruple its antioxidant content. Shred clean greens with your fingers, put in a plastic bag with a paper towel to absorb extra moisture, and keep in the fridge till the next day. Then toss with toppings.
