It should come as no surprise that nutrition and mental health go hand-in-hand. Not only does food impact our physical well-being, but it also plays a vital role in our mental well-being, too. In fact, it impacts almost every part of our system – from brain function and stress to hormone regulation and moodiness.

But what is the connection between nutrition and mental health and how can you improve your diet for a better balance? In this article, we’ll share information and a few insightful tips on using food to increase your psychological well-being.

The Link Between Nutrition and Mental Health

Did you know that your brain is directly connected to your stomach? The gut-brain axis is a network that allows the nervous system and gut microbiota to communicate with each other. For this reason, all the food that goes through your body has a direct impact on what information is sent to your brain.

For example, eating processed foods, unhealthy fats, and sugars can cause inflammation. If your physical body feels inflamed, this can contribute to depression and anxiety. Similarly, these foods can also cause your blood sugar levels to fluctuate. Between the sugar highs to sugar crashes, it’s easy to feel irritable, tired, or even groggy during the day.

On the other hand, some foods actually support a healthy gut microbiome. When this happens, serotonin is produced. This is a “feel good” neurotransmitter that mostly comes from what you eat and what is produced in the stomach. When you have a good microbiome, serotonin makes it easier for you to regulate your moods.

Foods to Boost Your Psychological Well-Being

Now that you understand the link between nutrition and mental health, let’s take a look at foods that are beneficial for your brain. If your diet restricts you from eating certain foods, you can always supplement your diet with a gut wellness vitamin or an all-in-one supplement.

Omega-3 Fatty Acids

Important for brain cell function, Omega-3 Fatty Acids can reduce inflammation. And as we said above, inflammation can cause all sorts of mental health problems like depression and anxiety. These acids are primarily found in fatty fish like salmon and sardines. However, you can also find Omega-3 in flaxseeds, chia seeds, and walnuts.

Antioxidants

Many people refer to antioxidant-rich foods as superfoods. That’s because these foods work hard to protect the brain from oxidative stress, which can lead to mood disorders. If you want to increase your antioxidant intake, eat more berries, spinach, and nuts. And for those craving sweets, dark chocolate is also rich in antioxidants!

B Vitamins

Your vitamin B intake is crucial for regulating your energy and mood. If you have a vitamin B deficiency, you may feel tired, moody, or even depressed at times. And long-term deficiencies are also related to cognitive decline. Therefore, try to ensure you’re eating lots of leafy greens, eggs, legumes, and whole grains.

Vitamin D

Vitamin D has a direct correlation on our mood. And while you can get vitamin D from the sun, there are lots of foods that are great supplements. Good sources of vitamin D include fatty fish, eggs, mushrooms, and fortified dairy products.

Complex Carbohydrates

Our blood sugar levels can have a huge impact on our mental well-being. In addition to cutting back on sugars, eating complex carbohydrates can also keep these levels balanced. They can prevent mood swings and even mental fatigue that comes with these energy dips. But keep in mind that not all carbohydrates are complex carbohydrates. Instead of eating white bread and pastries, opt for fiber-rich carbs like whole grains, legumes, and vegetables.

Probiotics and Prebiotics

You may know that probiotics and prebiotics are important for a healthy gut. And thanks to the gut-brain axis, they also happen to work wonders for your mental health too! Probiotics introduce good bacteria into your gut and include yogurt, kimchi, and sauerkraut. Prebiotics will feed the gut bacteria that are living there, ensuring they grow strong! Good sources of prebiotics include bananas, garlic, onions, and oats.

Foods to Avoid for Good Mental Health

Just as there are beneficial foods, there also happen to be foods that negatively impact your mental health. While you don’t need to cut them out completely, minimizing your intake can keep your cognitive health in check. These foods include:

Processed foods (chips, fast food, processed meats): These foods lack the nutrients needed for mood regulation. In addition, they’re made with trans fats and refined carbs that can cause inflammation in the brain.
Sugary foods (white bread, cereals, cookies, soda): These foods can cause high blood sugar spikes and crashes which can cause mood swings. Long-term effects of excessive sugar intake also include depression and anxiety.
Artificial sweeteners (diet soda, sugar-free candies): Ingredients in artificial sweeteners, like aspartame, have been shown to impact our serotonin production.
Trans fat foods (fried chicken, onion rings, doughnuts, margarine): Foods high in trans fats cause inflammation and oxidative stress in our brains. Both of these things can disrupt dopamine function which affects mood and may lead to depression.
Caffeine (coffee, energy drinks): Drinking too much caffeine can increase anxiety and prevent you from getting enough rest.
Alcohol: As a depressant, even the slightest bit of alcohol can reduce your serotonin levels. When serotonin decreases, you may feel irritable, moody, or even depressed. Alcohol can also impair our ability to regulate our emotions, making us feel anxious and even more stressed.

The connection between nutrition and mental health is almost as its impact on our physical well-being. Cooking healthy meals rich in vitamins and minerals can ensure that you’re keeping your body and your mind as strong as possible! However, certain supplements can also fill any nutritional gaps you may have. If you have any questions or concerns, it’s always best to consult with a doctor or nutritionist for more information.
