Rainbow Trout We already mentioned that salmon is a great option to fight aging, and trout is no different. Your body needs healthy fats because they protect your cells and promote longevity. But the reason trout is great because it’s high in EPA—a fatty acid that fights cortisol (the stress hormone). Try cooking trout in a pan with 2 tbsp of olive oil. Cook on each side for 5 minutes, or until you achieve your desired level of flakiness. We recommend cooking trout in olive oil.
