Mind Over Mood: The Right Foods to Improve Mental Health

by | Happiness

Let’s state the obvious right from the start…

Your diet can have a bigger impact on your overall mental health than you thought.

We usually look at therapy and medication as forms of treating mental health, but several studies have already proven in the last few years that food affects your brain too.

Also, some very smart folks have mentioned stuff along the way…

But, how does this happen? How are your gut and brain connected?

Great question…

The connection between your gut and brain [The Gut-Brain Axis]

Turns out these two, your gut and your brain, have a complicated relationship, but I guess science has made it very clear:

What you eat has a direct impact on your brain chemistry.

This means that certain nutrients support your brain function and reduce symptoms like depression and anxiety and, of course, you know what that means, some foods can play against your mental wellness.

But, the fascinating part of all this is the actual connection, for this post, anyways.

Connected by the vagus nerve, your gut and brain can send messages to each other…

  • Your gut can influence your emotions
  • And your brain can affect the type of bacteria living in your gut

Uff… The potential for a very vicious circle here, right?

If you want to learn more about this, I recommend you follow Dr. Uma Naidoo, author of This is Your Brain on Food.

How certain foods can affect your overall mental health

The main concern is how society depends heavily on processed foods.

A diet high in processed foods and sugars can lead to…

  • Inflammation
  • Oxidative stress
  • Imbalanced gut bacteria

All of them are directly linked to poor mental health.

The problem is they are responsible for triggering Dopamine in your brain, which is associated with the Brain Reward System.

According to Simply Psychology, “When exposed to a stimulus which is rewarding, the brain responds by releasing an increased amount of dopamine, the main neurotransmitter associated with rewards and pleasure.”

Say hello to Mindful Eating

Mindful Eating - Andrea Bahamondes

Are you a mindless eater?

Let’s be honest, many of us are. We consume food without paying attention to what, how, and why we are eating it. This can contribute to many negative mental health outcomes.

The solution to this is Mindful Eating, besides being a trendy term, is the art of caring and appreciating what we eat.

It involves paying full attention to the act of eating without distractions, slow eating, savoring each bite, and being fully present in the moment.

You can also care more about your ingredients, their sources, and how they are prepared. The point is that it helps you become more aware of your body’s needs and desires.

How to get started with Mindful Eating

With a bit of clean eating and some journaling, you can change your diet and possibly, your moods and emotional behaviors.

  • Remove all processed foods, sugars, etc. from your diet for a week
  • Little by little, start bringing some of those foods back into your diet
  • Make a note in your journal about how each one of those foods makes you feel
  • Now you can make some long-term decisions

Do you feel like a website undergoing an A/B Split Testing experiment? Good, because that’s pretty much what you’re doing.

All trends and buzzwords aside, simply start paying attention to how eating different foods make you feel.

The right foods to improve your mental health

It’s important to note that diet is just one aspect of mental health and should not be relied upon as a sole treatment for mental health conditions. However, incorporating these nutrient-rich foods into your diet can be a simple and effective way to support your mental health and improve your overall well-being.
