I'm looking for several psychologists, psychiatrists, and licensed therapists to share 1-2 eating habits that can improve your mental health and/or help to prevent dementia and cognitive decline.

After 20 years of seeing patients in the clinic, and with a strong belief that food is medicine, I usually recommend these two simple eating habits to support mental health and keep the brain healthy: 1. Eat Fermented Foods Fermented foods are full of probiotics that support the gut-brain connection and help keep digestion regular, both important for mental wellbeing and long-term brain health. Fermented legumes like tempeh and natto have been studied for their ability to support cognitive function and may even help slow or reverse early memory or language decline. 2. Include Omega-3-Rich Foods Omega-3 fats nourish brain cells and reduce inflammation that can affect thinking as we age. Foods like flaxseed, chia seeds, walnuts, and fish are simple ways to keep your brain sharp and memory strong.

To help support cognitive health and reduce the risk of cognitive decline, it is important to maintain a nutrient-rich diet that includes leafy greens, a variety of vegetables, and foods high in omega-3 fatty acids on a regular basis. Additionally, incorporating vitamin D-rich foods can promote overall well-being and contribute to improved cognitive functioning.

As a psychiatrist, I encourage two eating habits that support both daily mood and long-term brain health. The first habit is to "eat for your second brain"—your gut. Your gut and brain are in constant conversation, and a huge amount of your "feel-good" neurotransmitters, like serotonin, are made in your gut. An imbalanced gut microbiome can send signals to the brain that worsen brain fog, anxiety, and low mood. A simple way to support it is to add one "probiotic" or fermented food (like yogurt, kefir, or kimchi) and one "prebiotic" or high-fiber food (like an apple or oats) each day. The second habit is to focus on brain structure by eating fatty fish at least twice a week. I tell my patients to think of their brain as a house that is constantly under repair. Omega-3 fatty acids—the kind found in salmon, mackerel, and sardines—are the specific, essential materials needed for that repair job. Your brain is literally made of fat, and these specific fats are crucial for maintaining cell-to-cell connections. You can't build a strong, resilient brain with the wrong materials, and this habit is one of the most direct ways to protect against long-term cognitive decline.

Here's what we found in our Superpower data: people who ate more salads and less sugar were thinking more clearly. One user we tracked swapped sugary drinks for water and ate kale a few times a week, and he said his memory was noticeably better. My advice is to make small changes based on your own health data. Those personal tweaks seem to be what actually makes the difference.

Working with teens, I've found that breakfast is a game changer. A simple smoothie or oatmeal makes a real difference in their attention and cuts down on irritability. The kids who get omega-3s from things like walnuts or salmon seem to hold onto that focus better, their moods are steadier. My advice? Start with one small, consistent habit. That's how you actually get somewhere with their eating.

Expert Tip From a Psychologist: Foods & Daily Habits That Support Mood, Memory, and Long-Term Brain Health "As a licensed psychologist who evaluates cognitive functioning every day, I've seen firsthand how nutrition can shape memory, mood, and long-term brain health. A few simple food-based habits can meaningfully support mental clarity and may even help protect against dementia as we age. 1. Add broccoli sprouts or a sulforaphane-rich supplement like Broq to your weekly routine. Broccoli sprouts are one of the most powerful foods for brain health because they're packed with sulforaphane, a natural compound shown to reduce inflammation in the brain. Since neuroinflammation plays a role in depression and cognitive decline, including sprouts in salads, smoothies, or bowls—or using a standardized broccoli sprout extract—offers an easy, food-based way to support long-term cognitive protection. 2. Prioritize omega-3s with fatty fish or fish oil. EPA and DHA, found in salmon, sardines, and trout, are essential for healthy brain cells and communication between neurons. Eating fatty fish two times a week is one of the simplest ways to boost mood, reduce anxiety, and support memory. For people who don't love seafood, a high-quality fish oil supplement offers a reliable alternative. 3. Support your brain's energy with NAD-boosting foods. Our brain relies on NAD for repair and cellular energy, but levels naturally drop with age. Foods rich in niacin (like chicken, tuna, mushrooms, and peanuts) and tryptophan (like eggs and turkey) help the body make more NAD naturally. These small daily choices can support focus, reduce brain fog, and may help maintain cognitive sharpness over time. What I love about these habits is that they're simple, food-centered, and build up benefits gradua. You don't have to completely overhaul your diet—just add a few brain-friendly staples Psychological Testing.

As a physician who's spent years studying the connection between nutrition and mental health, I've seen firsthand how what we eat can shape how we think, feel, and age. One simple yet powerful habit I recommend is incorporating omega-3-rich foods—like salmon, chia seeds, and walnuts—into your diet. Omega-3 fatty acids support brain cell structure and communication, which can reduce inflammation and improve memory and focus. I once treated a patient struggling with mood swings and early cognitive issues who saw remarkable improvement after adopting a Mediterranean-style diet rich in these fats. Within months, her energy levels and emotional stability improved noticeably. Another key habit is practicing mindful eating. Instead of rushing through meals, taking time to notice textures, flavors, and feelings of fullness can lower cortisol levels and support a healthy relationship with food. In my practice, I've seen this approach reduce anxiety and emotional eating while promoting better digestion and nutrient absorption—both crucial for long-term brain health. Eating isn't just about fueling the body; it's about nurturing the mind through consistent, intentional choices.

When I started paying attention to how food affected my mood and focus I realized eating made the biggest difference. Eating fresh whole foods instead of processed ones made me feel more balanced throughout the day. It wasn't about following a diet it was about eating meals that felt clean, satisfying and easy to sustain. Over time that small shift brought more mental clarity and steady energy. What changed everything for me was learning to slow down during meals. Instead of rushing or eating while multitasking I started taking a few minutes to actually taste and enjoy my food. That small act of mindfulness not only improved digestion but also helped me stay calmer and more present. It reminded me how we eat can be just as important as what we eat. If it's something you're trying to improve I'd say start small and be consistent. Add one mindful meal a day or swap one processed snack for something natural and nourishing. Those small choices add up faster than you think. Eating well isn't about perfection it's about creating habits that make your mind and body feel supported every single day.

As a psychiatrist with experience in mental health and cognitive disorders, I often remind patients that what we eat has a strong effect on how our brain works. Two simple eating habits can make a meaningful difference for both mental well-being and long-term brain health. 1. Eating more whole, plant-based foods Fruits, vegetables, nuts, seeds, whole grains, and legumes are rich in antioxidants and vitamins that protect brain cells from inflammation and damage. Chronic inflammation is one of the factors linked to anxiety, depression, and later-life cognitive decline. Even small changes like adding an extra serving of vegetables each day or replacing processed snacks with nuts or fruit can support better mood and memory over time. 2. Choosing foods that support stable blood sugar Large spikes and drops in blood sugar can affect our energy, concentration, and emotional balance. Meals with good protein, healthy fats, and whole grains help keep blood sugar steady, which can reduce irritability, improve focus, and protect the brain as we age. It also helps lower risk factors like diabetes and high blood pressure, both of which are strongly linked to dementia. These habits are easy to start and sustainable in the long run. They don't require a strict diet but just more mindful choices that nourish both the body and the mind. When combined with good sleep, regular physical activity, and stress management, they can make a noticeable difference in overall mental well-being and long-term brain health.

Two eating habits that research consistently links to better mental health and reduced risk of dementia/cognitive decline are more Omega-3 rich foods and antioxidant rich foods. Omega-3 fatty acids, especially DHA and EPA, play major roles in brain cell structure and communication. They also help reduce inflammation which is associated with depression and age-related cognitive decline. Omega-3s can be found in fatty fish like salmon, sardines, trout, and mackerel, plant sources like walnuts, chia seeds, flaxseeds, and fortified foods or supplements. Omega-3s support memory and learning, are linked to reduced levels of anxiety and depression, and may lower risk of dementia. Foods high in antioxidants like berries, leafy greens, and colorful vegetables can protect brain cells from oxidative stress which is one of the most common drivers of cognitive aging. Antioxidants can help improve memory and processing speed, support long-term brain cell health, and are associated with slower cognitive decline in large studies.

I'm a licensed holistic therapist and spa founder who's worked with hundreds of clients dealing with stress, trauma, and hormonal imbalance. I've also formulated supplements specifically for mental clarity and nervous system support, so I've seen what works. **Magnesium-rich foods before bed** completely changed my own sleep quality and my clients' anxiety levels. I put magnesium in our MindYourMind formula because most people are deficient, and poor sleep is the fastest path to mental fog and emotional dysregulation. Dark leafy greens, pumpkin seeds, and almonds at dinner make a massive difference. One client who added spinach and pepitas to her evening routine reported her intrusive thoughts dropped by half within two weeks. **Medicinal mushrooms daily** for cognitive protection. I formulated our Mushroom 10X blend with Lion's Mane, Chaga, and Turkey Tail specifically because the research on neurogenesis and dementia prevention is solid. I've taken them for years and noticed sharper recall and steadier energy. The polysaccharides in these fungi literally feed your brain and gut microbiome, which directly impacts serotonin production. The gut-brain axis is real--70% of serotonin is made in your gut. If you're not feeding your microbiome properly, your mental health suffers no matter what else you do.

Healthy fats help maintain the structure of brain cell membranes and support blood flow to the brain. Diets higher in monounsaturated fats are linked to better memory and a lower risk of Alzheimer's disease. Good sources of healthy fats include olive oil, especially extra-virgin, avocados, nuts like almonds, pistachios, and cashews, and seeds like pumpkin, sesame, and sunflower. Healthy fats support brain cell flexibility and function, reduce inflammation, are associated with improved learning and memory, and are the core part of the Mediterranean and MIND diets. Also, foods rich in polyphenols help fight inflammation and oxidative stress, which are two major contributors to cognitive decline. Some foods and drinks high in polyphenols include green tea and black tea, dark chocolate at 70% dark or higher, berries, olive oil, and some herbs and spices including turmeric, rosemary, and cinnamon. These foods help to also support long term memory, reduce anxiety and improve mood, they protect neurons from taking damage, and they encourage healthy gut bacteria which can directly influence brain health via the gut-brain axis.

I'm Rachel Acres, a recovery coach and addiction counsellor with 13+ years of sobriety. Through my work at The Freedom Room and my own recovery journey, I've seen how diet directly impacts mental clarity, mood stability, and relapse prevention. **Consistent, protein-rich breakfasts within an hour of waking.** When I was drinking, I'd skip breakfast or just have coffee and pastries. Now I eat eggs or Greek yogurt with nuts first thing, and it's transformed my mental stability. My clients in early recovery who adopt this habit report 40% fewer mood swings and cravings. Stable blood sugar = stable emotions. The brain fog that comes from skipping breakfast mimics early cognitive decline and feeds depression. **Stop eating 3 hours before bed.** I used to eat late-night pizza while drinking--it wrecked my sleep quality even after I got sober. When I shifted my last meal to 6 pm, my sleep improved dramatically, and so did my morning mental clarity. One client who made this single change said her intrusive thoughts and anxiety dropped noticeably within ten days. Your brain detoxifies during deep sleep, and late eating disrupts that process, increasing dementia risk long-term.

I've seen how food directly changes my clients' moods and focus. One client started prepping simple snacks like mixed nuts and fruit, and their energy steadied up while anxiety spikes went down. Working these small, realistic food changes into their treatment made dealing with anxiety and depression feel much more manageable. It's a practical piece of the puzzle that really moves things forward.
