We are are in the middle of October this autumn, but it is an excellent idea to begin to build up our senior immune systems against the coming flu season.  Beside the well known natural substances that have been proven to boost immunity, such as the vitamins C and D, a new arrival has entered the immunity field.  When coupled with the old standbys vitamin C and D, this new arrival can form a strong, synergistic immunity team to fight the winter flu viruses.   The new arrival on our immunity team is Green Tea taken daily. Substances in the Green Tea appear to act in a way similar to the substance in the flu drugs Relenza and Tamiflu that fight the flu.   A recent study conducted in Asia reported that folks who consumed green tea at least six days a week reduced their risk of contracting flu by more that 45%.   Using all the members of the immunity team will provide an immune system boost for seniors.
