Can Your Diet Affect Your Mental Health?

Updated: May 6

The food we eat provides us with energy for the body, but it also contains important nutrients in the form of vitamins and minerals. Vitamins and minerals are essential to our body’s wellness as they enable the body to complete hundreds of jobs, which are vital for day-to-day function.

Vitamins and minerals help with energy production, hormone production, wound healing, immune system function, and much more. A deficiency of essential nutrients is known to contribute to the start of a decline in mental health in people suffering from anxiety and depression. Education is so important, yet many of us are unaware of the impact of what the foods we eat are doing, and in some cases, not doing for us.

We would like to share with you the vitamins and minerals that your body requires and some of the foods that you can find them in, which will enable you to plan your meals with more clarity and understanding.

“Insanity: Doing the same thing over and over again and expecting different results.”  — Albert Einstein

Something that is very important to remember is that every single one of us is completely unique, which means you could be more sensitive to some foods than others.

Keeping a food diary is a great way to help you understand what your eating habits and patterns are really like and can help you to identify the foods that your body may have an intolerance to.

What is food intolerance?

Food intolerance is a digestive response that occurs when something in a food irritates the digestive system or when a person is unable to properly digest, or break down a specific type of food. For example, gluten, wheat, or dairy. An intolerance is NOT an allergy. As our bodies change, so do its responses to certain foods, which is why mindful eating and body awareness is so important when it comes to body health.

Our bodies give us messages to help us to understand what it needs. When these messages are ignored, they send them as physical signals such as mental stress or anxiety and they worsen the longer the message goes unanswered. Take some time to listen to what your body needs, include some foods that contain the vitamins and nutrients it demands, and be sure to move every day. Stretch, walk, and rest.
