Anti-cancer actions

  • Reduces chronic inflammation — counterbalances the excess of pro-inflammatory omega-6
  • Inhibits tumor growth
  • Improves response to treatments
  • Reduces metastases

How to prepare it

Animal sources (EPA+DHA): salmon, sardines, mackerel, anchovies, herring, cod liver. Plant sources (ALA): flaxseed oil, walnuts, chia seeds. The goal is to rebalance the omega-6/omega-3 ratio (ideally 4:1 instead of 15:1 in the Western diet).

Recommended dosage

Small fatty fish (sardines, mackerel) 3 times/week. Avoid large predators (tuna, swordfish) as a mercury precaution.
