Combining selenium (found in tinned and fresh tuna) and the plant chemical sulforaphane (in broccoli) could protect your cells better than these compounds separately against becoming malignant. A study published in the journal Food Chemistry in January found that selenium and sulforaphane work together to boost expression of a gene that protects cells against the type of free-radical cell damage thought to lead to cancer.
Other good selenium sources are Brazil nuts, poultry, seafood and mushrooms, which could be teamed with any of the sulforaphane-rich brassica vegetables (cabbage, watercress, brussels sprouts, broccoli) for optimal effectiveness.
