According to a recent study, fish may be the most potent source of cancer-fighting omega-3 fatty acids. Yes, omega-3-rich foods are also touted for their heart- and brain-health benefits. Like many nutritious foods, they’re amazing multitaskers! The beneficial fats are thought to fight some types of cancer by activating certain genes in the immune system and helping to block the growth of tumors. While plant sources of omega-3s, such as flaxseed and walnuts, are also beneficial, they’re not nearly as effective as fish-based omega-3s. Eat two or three weekly servings of omega-3-rich fish, like salmon, for an array of health benefits, including potential cancer prevention. (If you don’t eat fish, consider supplementing with a DHA omega-3 supplement made from algae.)
