Guest Post: Can a Plant-Based Diet Impact Your Mental Health?

A healthy and balanced plant-based diet may improve your mental health and reduce symptoms of anxiety and depression.

According to the CDC, more than 50% of Americans will be diagnosed with a mental health condition at some point in their life. Depression and anxiety are among the top conditions that people suffer from.

As our society becomes more aware of mental health and more attuned to improving it, a number of potential solutions and aids have come to the surface.

One of the most recent theories is that a plant-based diet could help improve your mental health and reduce the effects of anxiety and depression. Today, I’ll examine this theory and show you some of the top research-based evidence so you can decide for yourself!

Can a Plant-Based Diet Improve Your Mental Health?

Obesity and physical illness aren’t the only drawbacks of an unhealthy diet. It’s no secret that our dietary choices have a huge impact on our mental health.

Our body needs specific vitamins, minerals, and other nutrients to support optimal hormone production and healthy brain function. Without them, our hormone levels can fluctuate drastically, resulting in symptoms such as:

  • Depression
  • Anxiety
  • Sleeplessness
  • And more…

Simply put – when we’re not eating healthily, our bodies will ultimately suffer, both physically and mentally.

Plant-based diets tend to be a lot healthier, compared to the average American diet that’s full of meat, sugar, and highly-processed foods. As a result, plant-based eaters tend to consume more plant-based nutrients than meat-eaters.

Meat does contain some essential nutrients. However, as long as vegans are supplementing with the best plant-based trace minerals to make up for this, they shouldn’t be negatively affected by the lack of meat in their diet.

Can a Plant-Based Diet Help Depression & Anxiety?

A growing body of evidence points towards the idea that a plant-based diet could improve your mental health. A recent study of 219 individuals revealed that those who adhered to plant-based diets were around 6% less likely to suffer from depression.

Six percent may not seem like a huge difference, but it’s certainly relevant. For those who suffer the daily effects of a mental health condition, a pharmaceutical-free solution (no matter how small the chances are) is certainly worth looking into.

Cognitive Dissonance & Plant-Based Eating

It’s easy to see how proper nutrient levels can correlate with healthier brain function. However, there’s a deeper aspect that’s just as relevant.

The American Psychological Association (APA) published a paper showing that many who suffer from depression also suffer from cognitive dissonance.

Cognitive dissonance is the mental discomfort that occurs when an individual’s beliefs about themselves don’t line up with the life that they actually live. It can also happen when an individual holds two conflicting beliefs at the same time.

For example, a part of you might really want to change your diet, improve your health, and start a plant-based lifestyle. The other part of you might also really enjoy meat, junk food, and other unhealthy things in your life.

Until you make a solid decision to follow one path or the other, you’ll likely feel uncomfortable. Sustained over long periods of time, these feelings can develop into depression or anxiety.

Once people commit to living a healthier lifestyle (which may include a plant-based diet), the positive decision can often feel like a weight lifted off of the shoulders. Stress, guilt, and indecision are replaced by focus, positivity, and clarity, which are naturally healthier emotions.

Not All Vegan Food Is Equal

When considering a plant-based diet to improve your mental health, it’s important to keep in mind the type of vegan food that you’re eating.

Not all vegan food is healthy.

Unfortunately, there are lots of unhealthy, highly-processed vegan foods that can be detrimental to your health.

I always recommend that plant-based eaters stick to natural, healthy whole foods, whenever possible.

Vegan Probiotics & Mental Health

Gut health often correlates with mental health. The healthier your gut biome is, the less likely you are to suffer from conditions like depression and anxiety. When your stomach is healthy, it’s able to absorb more of the nutrients it needs. Probiotics can even improve your body’s ability to create and absorb serotonin!

While vegans may not be able to consume yogurt (which is the biggest source of probiotics), the best vegan probiotics contain all of the essential bacteria needed to support a healthy gut!

Conclusion – Can Going Vegan Improve Your Mental Health?

As long as you’re consuming healthy whole foods and vegan nutrient supplements, then you may see improvements in both your physical and mental health! Vegan diets tend to be healthier than non-vegan diets and are more positive and ethical.

Combined, all of these things can lead to a happier state of mind, which can reduce the effects of depression and anxiety.

The Remarkable Link Between Diet & Mental Health

What should you eat if you want to boost your mood? Learn what to eat (and what not to eat) for improved mental wellbeing.

You may have heard of the “food-mood connection.” Research indicates that our diets greatly impact not only physical health, but mental wellbeing. Some foods seem to boost mood and reduce psychiatric symptoms while others are linked to depression and anxiety.

This article is about “mood thugs” and “mood champions.” Mood thugs are foods that can make you feel bad, while mood champions are foods that can give you a mental boost.


Mood Thugs

Sugar: Sugar consumption has been linked to depression, slows memory and learning, and reduces brain volume. Also, a recent study found that the concept of a “sugar rush” is myth. Sugar has virtually no impact on mood, regardless how much you consume. In fact, it can make you feel less alert and more tired.

Sugar is not the only villain; fat can be just as harmful. One study found that a high-fat diet may lead to symptoms of depression and anxiety. Furthermore, trans fat may lead to poor memory function.

Processed meats: If you have bipolar disorder, avoid processed meats such as jerky, hot dogs, etc. Researchers found that nitrates in processed meats are associated with mania.

Mood Champions

Vegetables: A diet high in fiber and vegetables (with limited added sugar) has been linked to improved mood and a reduction in depressive symptoms. Interestingly, women seem to benefit more than men, and the effect is even greater when exercise is added. A vegan or plant-based diet is associated with lower levels of depression, anxiety, and stress.

Raw produce: Fruits and vegetables are good for mood, but raw fruits and veggies are better. A raw diet is associated with higher levels of mental wellbeing and lower levels of psychiatric symptoms.

According to a recent study, the top raw foods associated with mental wellness are apples, bananas, berries, carrots, citrus fruits, cucumbers, grapefruit, kiwi, lettuce, and dark, leafy greens.

So how many servings of fruits and veggies should you eat per day for optimal mental health? At least 8, according to one study that found happiness benefits were evident for each portion for up to 8 servings per day.

Happiness nutrients: What nutrients should you include in your diet for improved mental health? Research indicates the following are important for mental wellbeing:

  • Omega-3 fatty acids (fish, flaxseed, walnuts)
  • Phospholipids (egg yolk, soybeans)
  • Niacin (liver, avocado, brown rice)
  • Folate (legumes, beets, broccoli)
  • Vitamin B6 (chickpeas, tuna)
  • Vitamin B12 (sardines, fortified nutritional yeast)

In sum, skip the fast food and soda; head to the salad bar instead to feed your mood and your belly!
