Is the paleo diet helpful for mental health? With advocates of this popular diet reporting a wide range of health improvements from less depression and anxiety to enjoying more energy, less kilos, better cardio health and improved digestion, the answer seems to be yes.

Here we take a look at what makes up the paleo diet and how it may help with mental health issues.

What is the paleo diet?

Whilst there are a few variations of this diet the core is based on a nutrient-dense, wholefood diet of meat, seafood, eggs, fruit, veggies, nuts and seeds. Throw in some fermented veggies, bone broth, herbs and spices and you have a good base.

“But what about all those saturated fats?”, I hear you wondering. Many paleo supporters eat pasture-fed and/or organically reared animal meats as these are considered to be healthier than their conventionally grown counterparts. These saturated fats are not quite the demon that they have been portrayed for the last few decades. And it is all about balance; most paleo consumers will have good serves of fresh veggies with many meals and avoid processed, denatured foods.

By default, the paleo diet excludes foods that are known to cause inflammation or damage in the body such as all grains, legumes, and dairy along with all processed and refined foods. Many of these foods are deficient in a variety of vitamins and minerals, as well as lacking other vital nutrients and quality fats.

Sometimes this diet is referred to as the ancestral diet or the hunter/gatherer diet. Almost ¾ of the worldwide hunter-gatherer communities derived over 50% of their energy needs from animal foods.

How the paleo diet may help mental health disorders

Building blocks of neurotransmitters

  • Animal foods are rich in quality protein, which is made up of various essential amino acids that form the building blocks of key neurotransmitters such as dopamine, noradrenaline, serotonin and melatonin; these play pivotal roles in mood and sleep.

Higher levels of cofactors

  • This wholefood way of eating potentially provides an abundance of vitamins and minerals; in particular, zinc, magnesium, B6, iron, and Vitamin C which are critical to making those brain chemicals.

Source of quality essential fatty acids

  • There is usually a good quota of quality fats in a paleo diet which are crucial for good brain function and healthy brain cells. The brain is more than 60% fat, hence eating the good fats and avoiding adulterated, processed fats such as those found in baked goods and fast foods is supportive for mood disorders.

No refined carbohydrates

  • Avoiding refined carbohydrates such as processed cereals, baked goods and the like helps the body better manage blood sugar levels which otherwise may impact your moods and energy levels. Some foods such as gluten, found in all wheat products, can have detrimental effects on brain function as well as elsewhere in the body.

Inclusion of fermented foods

  • These use to be included in the diets of many traditional cultures. Not surprising really when you consider the beneficial bacteria and the higher density of many nutrients. Many paleo diets include sauerkraut which may have a whopping 20 times the amount of vitamin C than raw cabbage!
  • Due to the gut-brain link, having diverse and healthy bacteria in your gut may have a positive impact on your brain health.

Nutrients to support liver detoxification

  • A paleo diet is generally dense in the nutrients needed to support your liver detoxification pathways. When your liver is functioning better there may be a knock-on effect on the health of your brain as toxins are cleared from your body and more nutrients are available to make those uplifting brain chemicals.

Some words of caution

Whilst paleo diets may be nutrient-dense, some people have issues metabolising oxalates, a compound found in many wholefoods such as spinach, almonds, berries and sweet potatoes which are often popular staples of a paleo diet.  Think spinach and blueberry smoothie with almond milk, almond cake and sweet potato wedges and you have quite an oxalate hit.

Having a compromised gut may contribute to oxalate toxicity which may manifest as kidney stones or calcium deposits in soft tissues, muscles, joints and even the eyes.

A paleo diet may help some people and their mental health issues but of course there is no one diet that fits all. It’s about finding out what works for you.
