  • Tea, Black and Green
    Green and black teas contain anti-inflammatory antioxidants that are good for preventing and managing arthritis, memory problems, and cataracts.

  • Tuna
    Tuna is a meaty fish (that's why it's often served as tuna steak) that is an excellent source of high-quality protein and omega-3 fatty acids.
