Are You Suffering from the 21st Century Epidemic?

How Stress Effects Your Health

Every spring that dreadful day seems to sneak up on us: Daylight Savings. Most of us will wake the morning of, and many mornings after, feeling drowsy or like we are "off" and need more sleep. This lack of energy will continue until our biological clock reprograms itself and evolves to the new time setting. Our natural rhythm has been disrupted—our internal clock is still saying it is one hour earlier than the time on the alarm clock. 

Because of the earth's rotation, almost all organisms function under a 24-hour day/night cycle called the Circadian Rhythm. This daily rhythm is not simply a response to alternating changes of day and night, it arises from an intrinsic timekeeping system referred to as the “biological clock.” This clock prepares us for changes in our physical environments, such as the rising and setting of the sun, and enables our cells and body systems to behave appropriately at the right time of day.  

Mammals have an area of the brain called the suprachiasmatic nucleus (SCN) that functions as the master circadian pacemaker, controlling when we sleep and rest, and when we are awake and active. Circadian rhythms also control:
  • Body temperature
  • Blood pressure
  • Heart activity
  • Oxygen consumption
  • Hormone secretion
  • Metabolism
Disruption of the circadian rhythm due to lifestyle factors plays a role in the development of metabolic disorders such as obesity and diabetes. 

It is widely accepted that an adrenal steroid hormone called Glucocorticoid (cortisol) has a daily variation in its circulating levels and is directly under the control of the circadian rhythm. Cortisol plays a crucial role in our adaptive response to various types of stress. Cortisol levels for a normal circadian rhythm look something like this: 

Circadian Rhythm
When we are under stress, our circadian rhythm is affected. There is, however, a huge variety when it comes to different types of stressors. The three major categories are:
  1. Emotional
    • Death of loved one
    • Working with or for someone that is unpleasant
    • Financial changes
    • Divorce
    • Moving to a new location
  2. Dietary (glycemic dysregulation)
    • Low carb diet
    • High carb diet
    • Alcoholism
    • Skipping meals
    • Ingesting foods that trigger an immune or allergic response such as gluten, dairy, corn or peanuts
  3. Pain and hidden inflammation/infection
    • Physical trauma such as motor vehicle accidents, sports injuries, surgeries
    • Diseases such as arthritis, bursitis, or anything that ends in “itis,” which means “inflammation”
    • Unknown influences such as liver toxicity due to heavy metal exposure, or infections that have gone undetected such as parasites and poor gut bacteria
Humans were not designed to endure chronic stress. 

We have not evolved to handle the modern day stresses listed above. Our bodies hold on to our innate need for survival—that is why the stress response is called "fight or flight." 

When we are locked in any of the situations listed above, we cannot handle it and, additionally, we have a revved up system that is unable to act. When this happens, cortisol levels go up and stay up. Consequently, we suppress our immune systems, causing blood sugar handling dysregulation, and we become unable to handle mental or emotional stress because we are stuck in over-reactive mode.

With constant overstimulation, many people experience HPA-D and cortisol dysregulation (the amount of cortisol available throughout the day and throughout our circadian rhythm cycle). HPA-D is a brain-to-body hormone dysregulation that affects many processes throughout and is the root cause of many chronic health conditions. HPA-D and an inefficient circadian rhythm can display any or all of the following symptoms:
  • Excessive fatigue
  • Dry skin
  • Neck/back pain
  • Inability to hold a chiropractic adjustment
  • Food allergies
  • Environmental allergies
  • Hair loss
  • Hormone imbalance
  • Irritability
  • Inability to lose weight
  • Fatigue headache
  • Poor immune response
  • Insomia
  • Depression
  • Cravings
  • Dizziness
  • Anxiety
  • Lack of concentration
  • Poor memory
  • Gastrointestinal issues such as indigestion or bowel problems
I see this daily in my practice as a functional nutritionist. We run a lab-based saliva panel that tests the cortisol level several times throughout the day to determine what the patient’s rhythm looks like and when it is deficient. Then we treat the underlying causes rather than the symptoms. This is functional medicine. 

People have chronic health issues not being addressed by mainstream medicine. While these health issues may require lifestyle and dietary changes, they also most likely require healing of HPA-D.

What you should know about heavy metal detox if you have an autoimmune disease.

When it comes to autoimmune conditions, many of my clients are eager to find answers about the foods that could be triggering their symptoms. They often think, "If I just avoid certain foods, I’ll feel better." But, what they might not realize is that food combinations can play a huge role in causing autoimmune flare-ups, even when the individual ingredients don’t show antibodies on their own. It’s a tricky and often frustrating area of functional medicine, but understanding it is key to healing. Here's what you need to know. Understanding Food Protein Reactions Let’s start with the basics. In a perfect world, food sensitivities and allergies are pretty straightforward. You eat a food, your body reacts, and you know exactly what caused the problem. Unfortunately, with autoimmune disease, the story is more complex. As a functional medicine practitioner trained under Dr. Datis Kharrazian, I don’t just look at individual foods—I look at immune response. And food proteins can behave very differently when combined. You may have a test that shows no antibodies for specific foods, think chicken, potatoes, or broccoli. But when those foods are cooked together in a meal, something changes. The proteins in those foods could combine in a way that causes your immune system to recognize them as a threat, triggering an autoimmune flare-up. The reason for this is cross-reactivity, where similar amino acid sequences in different food proteins can cause your immune system to confuse one food for another. This phenomenon is real, and it's something I see often in my practice. Just because a food doesn’t show a reaction on its own doesn’t mean it won’t cause issues when combined with others. The Role of Cross-Reactivity Cross-reactivity happens when your immune system mistakes one protein for another because they share a similar amino acid sequence. For example, if you react to salmon, you might also react to other types of fish due to similarities in their protein structures. This concept is why combining foods like certain grains, dairy, and legumes might trigger reactions in some individuals, even if they’ve tested negative for antibodies to those foods. Let’s look at a real-world example. Imagine eating a gluten-free Kung Pao chicken that’s free of contamination. You’d think that meal would be perfectly fine, right? But if that combination of chicken, spices, and vegetables triggers a reaction, it could be because of how the proteins in those foods interact once combined. Why You Should Pay Attention to Food Combinations In the context of autoimmune disease, where your immune system is already overactive, food reactions can be subtle and unpredictable. So, the next time you’re tempted to dismiss a food intolerance because a test didn’t flag it, think again. It’s not just about the individual foods—it’s about how they interact in your body. You need to pay close attention to how different food combinations make you feel. It’s easy to get caught up in thinking that food sensitivities only apply to the big culprits: gluten, dairy, or soy. But as an autoimmune patient, it’s essential to understand that your body might be reacting to the interaction of multiple foods. So while a test might show that chicken and broccoli are “safe” on their own, eating them together in a casserole could trigger symptoms. The N=1 Approach to Autoimmunity and Food Sensitivities Here’s the bottom line: There is no one-size-fits-all approach when it comes to food and autoimmunity. As I always tell my clients, you are the expert on your own body. Testing can give us a great starting point, but it’s your unique experience that helps us narrow in on what’s truly causing your flare-ups. This is why food sensitivity testing—while helpful—is just one part of the puzzle. You have to be keenly aware of your body’s reactions and the foods you’re combining, even if the individual ingredients test negative for antibodies. Don’t ignore what your body is telling you. If something doesn’t feel right after a meal, listen to it, and make adjustments accordingly. The Takeaway If you're struggling with autoimmune symptoms and haven't been paying attention to food combinations, it’s time to start. While food testing is an invaluable tool, it doesn’t give us the full picture. You may need to do some trial and error with food combinations to uncover what’s really triggering your symptoms. It’s also important to remember that autoimmune healing is complex and individualized. You are an N=1, which means your treatment plan should be tailored to you. Don’t be afraid to advocate for your health, and work with a functional medicine practitioner who can help guide you through the nuances of food reactions and autoimmune management.

For many of us, our experience with food comes with some sort of baggage. Maybe you eat to cope with stress, anxiety or depression. Maybe you’ve grown up with value-words placed on food such as “junk” and “healthy,” and told you couldn’t eat the “good stuff” (brownies and ice cream) until you finished the “yucky stuff” (broccoli and lettuce). Or, even more serious, maybe you or a loved one has struggled or is struggling with an eating disorder. Food is amazing and life-giving. It can be used as a means to celebrate, socialize, or simply just provide fuel for the body. Our relationship with food shouldn’t be a difficult one, it should be an enjoyable one. A way to get to that healthy place in your relationship is to practice mindful eating. Mindfulness is a Buddhist concept of mediation that can help you recognize emotions and physical sensations present. Through mindful eating, you can learn to truly pay attention to your experiences, cravings and physical cues. The basics of mindful eating are: Eat slowly, without distraction. If you are eating with others, take a least five minutes at the start of the meal to enjoy the food on your plate before engaging in discussion. Pay attention to your body--are you still hungry, or are you getting full? Learn to distinguish between cravings and true hunger. Use all your senses when you sit down to a meal. Make an effort to notice how the food looks, smells, tastes, feels in your mouth, and sounds when you chew. Appreciate your food, who has prepared it (even if it’s you--what an accomplishment!), and where it comes from.  Being mindful of your experience will help you slow down while eating. This can prevent overindulgence by making the act of eating intentional instead of automatic. It will also help you become aware of triggers that make you want to eat (are you truly hungry at 9pm every night when you sit down to watch that Netflix show, or do you just pour yourself a bowl of Chex Mix because that’s what you always do?). Knowing your triggers can give you time to process what’s truly going on and the ability to react properly.
