Yes! Anchovies, sardines, salmon, tuna, mackerel, and trout are all oily fish, which means they store oils throughout their bodies and are packed full of heart-and-brain-health-boosting omega-3 fatty acids, minerals, and fat-soluble vitamins. Unlike larger fish, sardines and anchovies don’t eat other fish and live shorter lives, so they don’t have a chance to accumulate high levels of toxic heavy metals before being harvested. So, you can eat them as often as you like without worrying about mercury! Plus, little fish are a more renewable and sustainable resource than larger fish, so eating them is healthier for the ecosystem as well as your body.
