The Mental and Physical Benefits of Fruits and Vegetables

Written by Karely Valdez



As one of PICA’s focuses includes food systems and food production, where we learn about how to grow sustainable food and the different impacts mass food production can have on the environment, I wanted to touch on how food in itself, impacts people's psychological and physical well-being. That is, how do the foods we grow and eat daily impact individuals mental health and physical body?


Focusing specifically on fruits and vegetables, this blog post focuses on the psychological and physical benefits of these rich nutrient foods that you are able to grow right from your own backyard! So let’s get started!

To begin, there has been evidence explaining how having a higher fruit and vegetable intake is related to better mental health, lower rates of perceived stress, as well as a decline in negative mood (Brookie, Best, & Conner, 2018). Not to mention, individuals who eat more fruits and veggies have a higher likelihood of optimal mental states including greater happiness and positive moods. (Brookie, Best, & Conner, 2018). Amazing right? Not only are fruits and veggies great for our bodies, but they benefit our mental capacity as well. Check out this video on How the food you eat affects your brain.


Further research that supports the evidence above, has shown that the foods we eat could be playing a role in the chemical composition of our brain, in turn affecting our mood (Huang, Liu, Suzuki, Ma, & Liu, 2019). Since fruits and veggies are rich in nutrients, including antioxidants, these foods have the power to modify serotonin status in our brain, leading to a positive mood (Huang et al., 2019). In other words, fruits and veggies can have a profound effect on how you feel!


So now let's get into some of the physical benefits of fruits and veggies!
