Get defensive
Mandarins
This time of year, citrus trees and markets are loaded with mandarins. These easily peeled fruits are smaller than oranges, making the trees more drought tolerant. You know that vitamin C is good for you, but did you know that satsuma mandarins are extremely high in decongestants? The USDA confirmed in 2008 that satsumas are high in synephrine, a natural defense against colds and allergies. Buy mandarins in bulk now, juice them and freeze the delicious medicine for allergy relief come springtime.
