4. Eat two servings of fatty-fish per week
Healthy diets rich in omega-3 fatty acids have been shown to reduce the risk of cardiovascular disease. Salmon, mackerel, sardines, trout, and herring are great sources of omega-3-fatty acids.
“EPA and DHA are omega-3s found in fish and fish oils that you need to keep your brain, heart, and eyes healthy as you age,” Brissette says. You should aim for two palm-sized servings weekly. Here’s another great reason to eat more fatty fish: “As you get older, your skin produces less vitamin D in response to the sun. Oily fish is an excellent source of vitamin D, so it’s another win for nutrition in your 40s,” Brissette says.
