We love ginger. That’s because in addition to adding delicious flavor to food, it’s also a natural antihistamine and decongestant, which means it can help relieve even the worst cold symptoms without any of the unpleasant side effects. Research has also suggested that ginger has anti-nausea benefits, and can boost anti-inflammatory and antioxidant activity within the body. Add a few slices of fresh ginger to stir-fries or soups, or make a cup of ginger tea. Simply simmer a two-inch piece of fresh ginger root in two cups of water, then flavor it with a little honey and lemon. On Nutrisystem, ginger is a Free Food.
