If you’ve ever been depressed, anxious or angry you know how emotions can impact your appetite. Any one of those experiences can make you eat more or less depending on the day and the intensity of what you’re feeling. And then what happens? If you skip some meals or binge on junk food, do you feel better or worse?
That’s what I thought. Eating or not eating has consequences that range from mental to emotional to physical, which makes nutrition very important in PTSD. Especially if you’re on a quest to reclaim some balance and self-regulatory control, you need to be giving your body — and your number one resource: your brain — what it needs to optimally function.
Your Best Brain Fuel: Glucose
I myself went the less eating route – for over twenty years. In a bid for control over a body in which I felt trapped and terrified I restricted food (I was anorexic) just to feel that I, and not my body or the past or some future trauma was in control. Restricting food became a game I played with myself: How long could I not eat and still be able to sustain activity and survive? Often, I’d wait until I was about to pass out before I’d eat some small thing. By doing this I felt, ironically, safer. The more stress and trauma I created for myself the more secure I felt knowing I could handle it. This process became a way I tested myself to make sure I was strong enough to survive whatever trauma came next.
Of course, giving in to those feelings really put my body, the past and some unnamed future trauma in control. Eating as little 500 calories a day you can imagine how fuzzy my head was, how poor my emotional control and how damaged my body eventually became. By the time I was thirty-five I was diagnosed with advanced osteoporosis, partially caused by my severe lack of nutrition.
The biggest problem with PTSD and nutrition habits, however, has less to do with bones and a lot to do with your brain and what it needs to optimally function. Your brain runs on the simple sugar, glucose, which can be found in grains, fruits and vegetables, refined sugar and dairy products. In order for you to have the energy you need to be able to manage emotions, create a sense of calm and make good decisions your brain needs enough glucose to run all of its systems at the same time.
When you don’t give your brain the fuel it needs, guess what it does? It shuts down systems that use large amounts of energy. For example, your willpower system, which can be enormously critical in PTSD management as it helps you make good decisions that influence what you think, feel and do. Without access to willpower, it can be very tough to achieve your recovery or coping goals.
When your brain conserves energy by shutting off high-energy consumption systems that leaves in charge your low-energy, lower brain processing systems. Know what those are? Your older brain structures that run on threat detection and emotion. Of course, in PTSD those systems are already hypersensitive, which means they work overtime, making your higher brain functions (those that include willpower) incredibly important to create balance in your internal experience.
Without glucose your brain can’t access all of the higher systems it needs, so the lower brain structures run the show, creating chaos as they overreact and you feel the spiral out of control. You can, however, help your brain process more effectively and efficiently. All you have to do is eat well, in a balanced and scheduled program.
