Did you know that in the next two decades, over 80 million Americans are expected to lose their memories to dementia and Alzheimer’s disease? What if I told you there’s a unique superfood that could lower your risk of memory loss and cognitive decline – and all it takes is incorporating this food into your diet once a week?
This remarkable superfood is none other than fish. Researchers at the University of Pittsburgh School of Medicine have discovered that consuming broiled or baked fish weekly can significantly improve brain health.
It’s About How the Fish Is Prepared
According to the study’s lead researcher, James T. Becker, “Our study shows that people who ate a diet that included baked or broiled, but not fried, fish have larger brain volumes in regions associated with memory and cognition.” Becker added that while the initial hypothesis centered around omega-3 levels playing a crucial role in brain health, the findings revealed a broader set of lifestyle factors affecting cognition – with diet being just one part of the equation.
Examining health data and high-resolution brain MRI scans of 260 subjects provided critical insights. Participants answered questionnaires about their eating habits, focusing on fish consumption and preparation. Researcher Cyrus Raji noted, “Baked or broiled fish contains higher levels of omega-3s than fried fish because the fatty acids are destroyed in the high heat of frying, so we took that into consideration when we examined their brain scans.”
The Benefits of Omega-3 Fatty Acids
The omega-3 fatty acids found in fish are a type of healthy fat that boosts brain function by improving communication between neurons. Consequently, participants in the study who consumed broiled or baked fish at least once a week experienced more brain gray matter in areas responsible for memory formation and higher-level thinking.
Becker explains that the findings suggest “lifestyle factors, in this case, eating fish, rather than biological factors, contribute to structural changes in the brain.” Adopting a combination of lifestyle choices can likely lead to improved brain health, preventing or delaying cognitive issues that may arise later in life.
Choosing the Right Fish for Brain Health
So, what kind of fish should you add to your diet for optimal brain health? The American Heart Association recommends consuming fatty fish rich in omega-3 fatty acids, like salmon, mackerel, herring, lake trout, sardines, and albacore tuna. Aim for two servings of fish per week, totaling about 3.5 ounces per serving, to reap the maximum benefits.
It’s important to note that certain fish may contain high levels of mercury, which can have harmful effects on the brain and nervous system, particularly in pregnant women and young children. Avoid fish with high mercury content, such as shark, swordfish, king mackerel, and tilefish. Opt for low-mercury fish like salmon, shrimp, canned light tuna, and catfish.
The Environmental Defense Fund even has a helpful guide to help you choose the tastiest and safest fish options.
Diet and Lifestyle Choices for Brain Health
Besides eating broiled or baked fish for its omega-3 content, remember that maintaining overall brain health involves an array of lifestyle factors. Here are some additional ways you can promote a healthy mind:
- Exercise regularly. Physical activity has been shown to increase brain volume and improve cognition. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week. As an added bonus, regular exercise also helps reduce your risk of cardiovascular disease and other health conditions.
-
Embrace a nutritious diet. A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats can not only improve heart health but has also been linked to better cognitive function as we age. Consider adopting the Mediterranean or DASH diet, both of which have been shown to improve brain health.
-
Stay cognitively engaged. Engage in activities that challenge your brain, whether it’s learning a new language, taking up a musical instrument, or playing strategic games like chess. By keeping your mind active, you can help maintain cognitive function over time.
-
Prioritize sleep. A good night’s rest is essential for healthy brain function. Aim for 7-9 hours of sleep per night, and establish a consistent sleep schedule to help ensure you wake up feeling refreshed and energized.
-
Manage stress. Chronic stress can have negative effects on both physical and mental health. Find ways to cope with stress, such as engaging in relaxation techniques, practicing mindfulness, or seeking professional help when needed.
The secret to maintaining a sharp memory and healthy mind lies in making the right choices for both your diet and your lifestyle. By incorporating broiled or baked fish into your diet – along with exercise, balanced nutrition, cognitive engagement, sleep, and stress management – you can boost your brain health and help protect it for years to come.
