NUTRITION 101: UNWELCOMED SURVEILLANCE


The IMMUNE SYSTEM, as you read about in last weeks post, is a complex and essential component to human health. From blocking bacteria before they have a chance to break into our bloodstream, knocking out viruses prior to their replication, and destructing the walls of parasites, yeasts, and fungi, our immune system acts as a 24/7 silent system-wide surveyor. While immune reactions are typically meant to be acute (or short-lived,) over-activation of our surveillance teams can lead to some serious issues. Read on to find out what can trigger such chronic reactions, and their effects on our health.



CHRONIC CONUNDRUM:
You slice your finger wrapping holiday presents, sneezing shoppers surround you at your local mall on Black Friday, or perhaps, your toddler tracked in a case of strep throat from his/her pre-school.  Exposure to viruses, bacteria, and physical damage all signal the immune system to release a slew of cells, chemicals, and additional reactions to help the body heal as quickly as possible. From triggering the INNATE immune system to heal cuts and scrapes to mobilizing antibodies and t-cells via our ADAPTIVE immune system to aid in the destruction and removal of bacteria and viruses, this system acts like a tightly regulated orchestra. For the most part, the activation of these cells is short-lived, quickly turned off as soon as the danger has been averted. In the case of chronic inflammation/immune-stimulation, our immune responses begin to degrade the very cells and tissues they were originally assisting. 
Chronic inflammation, as triggered by high stress, pro-inflammatory diets, hormonal imbalances, and persistent infections, can inhibit the regulatory mechanisms our immune system has in place. When you add on additional aspects such as improper sleep and inadequate nutrition, the once controlled immune reaction trickles out into areas of the body that are perfectly healthy, which can lead to system-wide damage and even more (unnecessary) inflammation. You often hear of autoimmune disorders, which are classified as diseases in which the body’s own cells enact a “civil-war” of sorts against one another. Rheumatoid arthritis, fibromyalgia, multiple sclerosis, hashimoto thyroiditis, and more are all such diseases. In these cases, our body loses the ability to differentiate between foreign invaders (bacteria, viruses, parasites, and toxins) and our own tissues, leading to a whole host of symptoms, health defects, and in some scenarios, chronic illnesses.



FUELING THE FIRE:
While genetic variability can make one more or less susceptible to having an over-reactive immune system, it only accounts for 1/3 of the likelihood that we actually get a chronic disease or autoimmunity. So where do the other 2/3’s factor in? As noted above, certain aspects of our nutrition and lifestyle can greatly affect our body’s ability to maintain and regulate proper immune responses. While the obvious answer to what causes over-active immune stimulation may be excessive exposure to bacteria, viruses, and other “bugs,” some unlikely factors are worthy of taking note:

PROCESSED FOODS: Fast food and highly processed foods are the obvious additions to this list, most notably for their high sugar contents, chemical flavorings, colors, preservatives, and pro-inflammatory (Omega 6) fats. Excess sugar can promote insulin spikes, the body’s sugar-controlling hormone, which in high amounts is pro-inflammatory. In addition, too much sugar in the body can fuel harmful cellular growth, and slow down the ability for our white blood cells (remember those pac-men) from doing their jobs. Omega 6 fats, commonly found in vegetable oils (soybean, canola, corn, etc,) turn on pro-inflammatory pathways, and chemicals like artificial ingredients and preservatives tax our detoxification system.

ANTI-NUTRIENTS: While most of us understand that junk food like Tastycakes and McDonalds French fries contribute to ill health, unlikely immune-stimulators exist in foods that are often deemed “healthy.” Anti-nutrients are components of certain plant-foods that are produced by that food to protect itself in its environment. Whole grains, beans, and legumes, contain compounds known as agglutinins, which deter predators from eating them. Also known as lectins, such proteins found in foods including kidney beans, wheat, soybeans, peanuts, and tomatoes, are difficult to digest (feeding harmful strains of bacteria,) can damage our gut-wall (leading to a leaky gut) and overly stimulate the immune system. Alkaloids and saponins found in certain legumes and seeds (amaranth and quinoa) as well as nightshade vegetables (eggplant, mushrooms, peppers, tomatoes, etc,) can also contribute to similar damage, and certain plant-alkaloids are actually used in vaccines as immune adjuvants (immune stimulators!) **While I am in NO way saying to avoid eating such incredibly nutritious foods (I personally consume them on a daily basis,) soaking, sprouting, and removing seeds can all help negate some of the potentially negative aspects.

SLEEP, STRESS, and SEDATION: Lack of proper sleep and chronic stress (work, school, life in general) can shift hormonal balance, leading to excessive levels of the stress hormone CORTISOL. While cortisol has anti-inflammatory properties, “misuse” of this potent hormone can actually lead to a ‘dumbed-down’ immune response. So while you are under high-stress, you may feel fine (no signs of sniffling or sneezing,) with just a low-grade feeling of “being-off.” Perhaps you “haven’t been sick in years,” or tout being the only one in the office that hasn’t gotten the yearly “cubicle cold.” Our immune system, when working properly and optimally, will, and always will, initiate a response. Despite being the healthiest eater or exerciser of the bunch, if you are truly healthy, then you will have an immune reaction. The length and severity of such a reaction will be different, however, it will more then likely occur. So when one is under high stress, that cortisol response quiets our immune response, even when you need it the most. This allows seemingly innocent cold and flu bugs to grow into big, bad “wolves”. Wolves that are much more difficult to beat once your cortisol levels are brought back down and your stress load is back in check (say, while you –finally- take that work vacation to the Bahamas.)  In addition, sleep is a time that our body is able to regenerate itself, reproduce specific compounds and cells that assist overall health (such as immune cells,) and a time for complete cellular detoxification (sayonara gunked-up junk!) Lastly, physical activity (both in excess and not-enough) can also contribute to systemic inflammation, and so finding your personal balance is key to ensuring you stay healthy all through the year.

GUT CHECK: An entire month worth of posts pertaining to the importance on gut health and immunity exists on the blog, all of which can be found here. In short, when your gut-wall has been broken down, bacteria, viruses, pathogens, and even non-harmful food substances can “leak” out into the bloodstream prior to properly being broken down/processed. This can lead to immune reactions throughout the body, from your brain (hey there migraines,) to your joints, and even your glands/tissues, and organs. A leaky-gut can lead to chronic inflammation. Contributing factors include pro-inflammatory foods (noted above,) high stress, and bacterial imbalances. Read all about gut health here.




SYSTEM BREACH:
Hippocrates, the father of Medicine, stated, “All disease begins in the gut.” When a diet that is high in pro-inflammatory foods is paired with a lifestyle loaded with stress, toxins, and poor-habits, gut and immune health are taxed, leading to a “breach in the system,” which can potentiate auto-immunity and chronic inflammation. Now that you know some of the additional factors that contribute to a hyper-active immune system, look for next weeks post all about specific foods and practices you can implement to help tame your inner flame.
