Does What You Eat Affect Your Mental Health?

Short answer - YES!


There is no question about it, but it seems there are people wondering what the connection is.

It's no secret that eating healthier can make our physical body feel better, but what about mentally? There have been multiple studies done to prove the connection. Going as far as eating a range of healthier choices can help with symptoms of depression and anxiety. While the not-so-healthy choices can potentially lead to early signs of dementia and stroke.

We are sure of two things though and according to the UK Mental Health Foundation, there are two groups of foods that have a negative effect on the brain:

  • foods that trick the brain into releasing chemicals we may be lacking, temporarily altering our mood (for example, caffeine and chocolate) Interesting as many of us use chocolate as a mechanism.

  • foods that prevent the conversion of other foods into nutrients the brain needs (for example, saturated fat such as butter, lard and palm oil).

Clear as mud? Let's talk micronutrients!

These very important nutrients are required in order to keep us mentally healthy and yes guess what. They come from your diet or supplementation.

Vitamin D; activates the gene expression of enzymes that help produce neurotransmitters

B-vitamins; help synthesize DNA, maintain the fatty myelin covering over neurons, and help produce mood-altering neurotransmitters

Antioxidants; prevent oxidative stress that can lead to DNA damage and conditions like depression and anxiety

Omega-3; required for healthy cell membranes

Fiber; helps maintain a healthy population of “good” bacteria in your gut and have been shown to reduce anxiety and depressive symptoms

Along with many signs and symptoms of deficiencies, if you think you are deficient in one of these nutrients, I recommend seeing your doctor.
