Worried Sick?

Is my Stress Normal?Photo Credit Bernard Goldbach

Or has our society collectively acquired a new norm of a stressful behavior? The underlying omnipresent knowledge of our “to do list” can vampire the enjoyment out of the very moments we are working on that “to do list” or trying to relax. Our bodies get tired and we just want to relax, but feel guilty to when there is so much unfinished. What will people think of me? Am I irresponsible? Am I a bad person? Maybe as long as I stay busy and “Do” I actually momentarily get some relief from self judgment. 

Deeper than Anxiety

Energetically Anxiety is fear of making an incorrect decision or mistake. This causes the person not to move in any direction, which in turn makes them feel stuck and trapped in their circumstances (which they may have created themselves from fear of making decisions). This may also manifest in the tendency to over research to find answers, feeling confused with conflicting information, and not making a quick decision to action. This keeps you longer in your unfavorable circumstance. 

Anxiety is also related to fear of abandonment, which can manifest in feeling a need to “Do” something, in order to keep other people happy and therefore “like you” and not abandon you. There’s a sense anxious people feel, that their world is not safe, so worrying is somehow a twisted way to make them feel temporary relief. Why is that? 

How does the Brain Interpret Reward?

Feel a low level of guilt or shame over small things in life? For some, it’s the guilt or shame that you feel, that gets interpreted as stress. We have a reward center in the brain called the nucleus accumbens. This part of the brain regulates how we feel pleasure associated with reward for a behavior. If you got rewarded with food when you finished your homework as a kid, you may link food to reward as an adult, perhaps over eating to emotionally feel good. If you got punished when you did not do homework, that punishment also registers in the nucleus accumbens, the reward center. This is why people oddly get addicted to guilt, shame, or punishing themselves. This may be why it’s so hard to break the cycle of worrying and just let go. 

How does Stress Make you Sick?

In a journal published by the Immunology Allergy Clinic of North America Titled “Stress and Allergics Diseases”, it is estimated that over 75% physician visits in America are stress related. Stress increases susceptibility to infections, autoimmune disease, allergies, and inflammatory bowel disease, and negatively affects the outcome to cancer and aging. Studies show that maternal stress while pregnant increases the child’s risk to developing asthma and allergies.

Stress impacts the immune system by increasing the secretion of cortisol and catecholamines. The stress hormones increase stimulation of TH2 type T cells, increasing the production of IL-4, IL-10 and IL-13, which favors an allergic inflammatory response. Cortisol unfortunately suppresses TH1 type T cells and thus IL-12 which is important for natural killer cell function, which decreases susceptibility to viral infections and cancer. 

Stress stimulates the sympathetic nervous system, which increases the release of Substance P (SP) which is related to pain and inflammation. Stress also increases the release of Vasoactive Intestinal Peptide (VIP). VIP increases vasodilation, secretion of water (which may increase edema, bloating, or diarrhea), and smooth muscle relaxation (may increase GERD symptoms). According to the British Journal of Medicine, increased VIP and VIP nerve receptors are associated with some inflammatory bowel disease. 

Stress definitely can make you sick, and takes away your enjoyment of life. Stay tuned and I will share some strategies to help you overcome stress in the next newsletter. In the mean time, remember the good things in life and laugh a little.

Problems Focusing and Lack of Motivation

Do you have a huge, to do list in front of you and feel no motivation when you think, or look at that list? It would certainly feel so good to get things done, but yet, you feel tired, unfocused and not sure where to start. Then the guilt builds up, and you feel bad you are so behind. You think, “What is wrong with me?” Is this a motivation issue, or a health issue? It can be both, but we will discuss how balancing the physical body can improve concentration, clarity of mind and mood today, which will make it easier for you to feel motivated.

I’ll talk about 3 common causes of brain fog and difficulty focusing that I have seen in my practice. I’ve helped patients with ADHD, who did not do well with medication, use natural methods and heal. Many of my patients then function normally after I work with them, with no more traces of ADHD behavior. Some patients do not have ADHD but feel that they have difficulty with their memory, slower mental performance, or even difficulty making decisions. These patients were happy to find out that Candida, Food Allergies, or Heavy Metal Toxicity was causing these symptoms. 

Heavy Metal Toxicity:

Lead can be found in old paints, old water pipes, children’s toys from China, and contaminated soil. Inorganic mercury from dental amalgam fillings, vaccine preservatives, and organic mercury in fish such as tuna and swordfish are sources of mercury toxicity. Aluminum can be found in foil wrap, aluminum cookware including many non-stick pans, some medications (used as fillers), deodorants, certain water bottles and canned foods. Many of these heavy metals are neurotoxins and some have been linked to Alzheimer’s disease, memory loss, and some mood disorders. Because most people have slow, small dose exposures to these heavy metals, most blood tests from your doctor will not show that you have elevated levels of these toxins. Heavy metals are attracted to fatty tissue, so they tend to get stored deep in your cells, in the brain or nervous system tissue where fat content is high, therefore being especially toxic to the brain and difficult to test for. I use some other testing methods that can detect smaller amounts that are hidden in the body. 

Candida:

Candida is a type of yeast, which is present in the intestinal tract as normal flora, but often overgrows and causes health problems such as brain fog, difficulty making decisions, anxiety, depression, problems focusing, and moodiness. Other tell tail signs that you may have an overgrowth of yeast include bloating, gas, genital itching, toe nail fungus, itching under the breasts or in the groin area, vaginal yeast infections, oily skin or scalp, dandruff, and poor digestion. Often when patients use anti-fungal medication over and over again, they yeast just grows back because the body is in a state of imbalance, which serves as a great environment for the yeast to propagate. In Chinese medicine, a state of damp heat often is associated with candida problems. Some homeopathic remedies are very effective at breaking the cycle to Candida overgrowth. If candida is the cause to your difficulty focusing and moodiness, it is definitely worth to address it now. I use the probiotic, Ultra Flora Acute Care by Metagenics, because it has a few strains of probiotics such as S. boulardii that is specific against candida. 

Food Allergies:

Most people associate food allergies to anaphylactic reactions such as swelling of the throat, lips, or face. However many people have much more subtle reactions to foods, including brain fog, fatigue, sleepiness, irritability, anxiety, gastrointestinal symptoms, or heart palpitations. If your pulse rate increases by 8-10 points per minute after eating, it is likely you ate something you had a food sensitivity to. 

Have you experienced eating and then feeling very sleepy right after? Besides a blood sugar crash, you may actually have a food allergy or sensitivity. The problem with continuously eating foods that your body is reacting to is that it triggers the body to be in a low grade state of inflammation which slowly damages your organs and can be related to allergies, asthma, auto-immune diseases where your body attacks itself when it is mistakenly trying to attack the epitopes of the foods. Some children with ADHD have been completely cured by avoiding their food allergens, which is a huge relief to parents. 

Again, there are many causes to each disease or symptom, so it is very important for a qualified doctor who understands how the body works holistically in order to identify what the problem is. Below is a video I’ve filmed discussing the various types of food allergy and sensitivity tests, and why most of the tests you get at the doctors office may not be accurate for food sensitivities.

What is the Difference Between a Food Allergy, Food Sensitivity and Food Intolerance? And What are the Best Tests?

Many of my patients ask me about food allergies and what the best tests are. I thought I'd write an article to clarify. There has been a sharp rise in food allergies and I've noticed many urban restaurants now have gluten free options. Servers will often ask a party if there are any food allergies before taking orders. More people are much more conscious of food sensitivities. In fact, there are studies showing links between food sensitivities and difficulty losing weight, autoimmune diseases, and gastrointestinal diseases. Some patients achieve some type of relief by avoiding certain foods.

However, I've seen patients who are so sensitive that the list of foods they can tolerate is so small, that their quality of life does not seem so fun. I feel it is important to identify food sensitivities and avoid them for a period of time to allow the body to calm down. I do not feel that it is optimal for a person to be permanently "allergic" to say 50% of all foods tested. This often means that there may be intestinal permeability issues that allow too much exposure of food antigens to the immune system. In these cases, it is very important to also work on improving intestinal health as well as immune modulation in addition to working with food allergies.

More information on food allergies, sensitivities, intolerances and testing options are below.

Food Allergies:

IgE Food allergies occur when the immune system makes antibodies to foods. This is a very specific reaction like a lock and key. If the antibodies made are IgE antibodies, the reaction is usually immediate. These reactions can be immediate fatigue, immediate hyperactivity, swollen lips, abdominal discomfort and respiratory symptoms. An IgE mediated reaction is what we classically call a food allergy. Usually anaphylactic reactions fall into this category.

If the antibodies produced are predominantly IgG antibodies, the reaction is often delayed sometimes 24-48 hours after eating the offending food, making it more difficult to pinpoint a correlation. Sometimes the symptoms that show up may be subtler, such as poor concentration, chronic respiratory symptoms, chronic behavioral issues, and frequent illness.  These non-distinct reactions make it difficult for people to realize that they have a food allergy but knowledge of this can be very helpful. For example, people with chronic diseases such as autoimmune diseases, chronic pain and inflammation, allergies, asthma, headaches, itching and fatigue tend to have underlying food allergies.

Food Intolerances:

Food intolerances occur when the body lacks enzymes to digest a certain type of food. A classic example of an intolerance is lactose intolerance, where an individual lacks the enzyme lactase that breaks down lactose, a sugar found in dairy products. Thus people with lactose intolerance usually will have symptoms such as abdominal pain, flatulence, diarrhea or fatigue when consuming milk products. A lactose intolerant individual may also have an allergy to milk in addition to the intolerance. People who have an intolerance often feel better by avoiding the food, but in mild cases can consume the food with a digestive enzyme given to help the body break down the food.

Food Sensitivities

This is a non-specific immune response to food. For example, white blood cells may swell, change morphology, or rupture in response to exposure offending agent. This is not an allergy because an antibody is not produced. These reactions are often harder to identify and may be an underlying problem contributing to weight problems, chronic disease, behavioral issues to name a few. These types of sensitivities often show up with an ALCAT testing when a skin prick test or RAST test is negative. 

Testing:

Skin prick allergy tests usually measure IgE antibodies. They are very good for detecting environmental allergens and some food allergies that tend to be more severe such as peanut allergies. Skin prick tests are generally not good tests to test for foods because they often show false negative results. A RAST test is a blood IgE test that may be more accurate for foods than a skin test.

IgG blood tests give some additional insight and show allergies that are subtler and delayed. These reactions still trigger an inflammatory response that is usually not as acute or obvious. But this chronic low-grade inflammation can be enough to release enough inflammatory chemicals that can cause more oxidative damage to the body.

The gold standard for finding problematic foods is the elimination challenge test. Patients restricted to 4 non-allergenic foods for 2 weeks, then re-introduced one food at a time and monitored for reactions. Data shows this is more accurate than any of the laboratory tests. However, this is often difficult to do and very labor intensive.

ALCAT Laboratories offers a blood test that measure the change in size of white blood cells when exposed to certain foods, thus measuring the immune reaction to the food, rather than anti-bodies. The immune system can react to what it perceives as an intruder without making antibodies. This test is personally my favorite test and seems to be much more clinically relevant than the RAST test. A study done at the Department of Pediatrics in Pavia Italy showed that patients with gastrointestinal symptoms who tested negative for allergies (skin prick, and RAST), when following the ALCAT food elimination had improvements in their symptoms. ALCAT tests picked up what some of the other tests did not. Another study showed that patients who were unable to lose weight on a low calorie diet, who followed the diet plans according to their individualized ALCAT tests observed significant decrease in body weight according to the Middle East Journal of Family Medicine. Lastly according to the Medical School of Cape Town Africa, ALCAT testis high a high degree of reproducibility.

Some doctors such as myself will also use kinesiology or muscle testing in addition to the blood tests. I sometimes find that muscle testing gives more accurate results than any one of these blood tests used alone, and I postulate that muscle testing combines all types of reactions the body has to the food, as we attempt to energetically get information from the body.

According to Dr. Mark Hyman MD, these are symptoms to look for if you suspect a reaction to certain foods. Many of these symptoms are generally not thought of in relation to a food, but can be a tell tail sign that there may be some benefit to finding out if you have any food sensitivities or intolerances. Many of these symptoms are vague and may be associated with other medical conditions as well, so consult your health care provider.
