Is Burning Candles Good For Your Health?

Dr. Phelts sees many patients at his New York, NY practice,  who say that candles cause them to have various symptoms.  Is there any validity to their claims?  What is interesting is that they mostly complain of respiratory symptoms.  Recent research provides some insight into candles causing respiratory problems and why it could be bad for your health.

A study from Copenhagen University conducted on mice found exposure to substances from burning candles to cause greater damage than the same dose of diesel exhaust fumes. The study showed that candle smoke causes lung inflammation and toxicity, arteriosclerosis (hardening of the arteries), and ageing effects on chromosomes in the lungs and spleen (which could increase the risk of developing cancer).   

In addition, a study in 2009 by U.S. researchers found that paraffin-based candles release carcinogens (cancer causing substances) and chemicals that may raise the risk of asthma attacks.

The U.S. Environmental Protection Agency reports that scented candles produce more soot than unscented.  Soot can get into your lungs and cause damage to your respiratory system. The longer the candle wick, the more air pollution it produces.

Dr. Phelts recommends avoiding candle burning all together.  If you must burn them, it is best to do it only occasionally.  You may want to try soy or beeswax candles, since they are less toxic to the body.



N-Acetyl Cysteine For Ear, Sinus, and Respiratory Infections

Cold and flus season is approaching.  Dr. John Phelts, DC in New York, NY recommends that his patients keep a bottle of N-acetylcysteine (NAC) in their medicine cabinet.  NAC is an amino acid that helps our bodies fight infection. Our body manufactures NAC, but when fighting an infection, supplementing with it can be very beneficial.  It can help us fight both respiratory and ear infections.  Researchers have found NAC to be beneficial both as an added treatment to conventional antibiotics (outcomes were improved) and as a standalone treatment. This is most likely because NAC has both mucolytic (breaks down mucus) and antimicrobial properties.  It is the mucolytic attribute that makes it so effective.  When mucus is thick, it makes drainage of the ears, sinuses, and nasal cavities difficult.  This makes a perfect breeding ground for bacteria.  By thinning the mucus, it allows the mucus to drain into the stomach, where the acid kills the bacteria.

Dr. Phelts uses NAC for himself and his entire family.


Garlic For Infections

Dr. John W Phelts, DC helps many people who have immune system challenges.  Many come to him at his New York, NY office seeking natural alternatives for resolving infections.  Garlic is one of many remedies that he recommends to support the immune system.

Garlic contains over 200 phytochemicals that possess antibacterial, antiviral, and antifungal properties. Garlic contains an abundance of sulfur, and it is sulfur compounds that give it its immune assisting abilities. These compounds are known as allicin, alliin, and ajoene.

Raw garlic is best for maximums potency.  Be aware that the potency of garlic supplements (powder, capsule, extract or oil) can vary widely because allicin (the active ingredient) is very sensitive to methods of preparation. Many manufacturers age garlic to reduce its odor, but this also reduces the allicin present and compromises the strength of the product.  Therefore, avoid odorless garlic supplements.

Though generally safe for most people, taking a garlic supplement can cause heartburn, upset stomach, an allergic reaction, and breath and body odor (common with raw garlic). Garlic should not be taken by persons who are preparing for surgery or who have bleeding disorders because it can impair the body's ability to form blood clots.

Dr. Phelts can help you determine which formula works for your health and wellness needs.  He performs a simple test to determine if garlic is an appropriate medicine for you.


How Intensely Must You Exercise To Live Longer?

Current ongoing study research the Copenhagen City Heart Study compared light jogging, moderate joggers, strenuous joggers, and sedentary individuals.   The study includes 1000 joggers and 400 healthy non-joggers.  They found that the death rate of light joggers was 90% less than non-joggers, and 60% less for moderate joggers vs. non-joggers.  The death rates for strenuous joggers and sedentary non-joggers were not significantly different.  Jogging for a total of one hour/week had the lowest death rate.  The researchers pointed out that the best combination was jogging at a light to moderate pace at a total 60 – 145 minutes/week.

Dr. Phelts is a chiropractor and applied kinesiologist in midtown-Manhattan, New York, NY.



Chiropractic Can Help Prevent Surgery for Back Pain

New York Back Pain Treatment without SurgeryThe latest numbers show that there are over 500,000 spinal surgeries annually in the US. Although sometimes it's necessary to have back surgery, the fact is that if you can prevent this type of invasive procedure, you're often better off.

Dr. Phelts is here to make sure that patients in New York have a natural, non-surgical option for back pain. We've helped many patients heal from back pain without the need for surgery.

There are many reasons to avoid unnecessary medical treatments: Surgeries often result in a longer recovery time and complications, neither of which is an acceptable scenario. Fortunately, as one study has found, chiropractic may actually keep you off the surgeon's table completely.

Research Proves Chiropractic Care Helps Avoid Back Surgery

In this report, about 1,900 workers with back injuries were assessed over a three year period. When the workers first sought treatment with a surgeon, over 42 percent ended up having back surgery. For subjects who saw only a chiropractor, only 1.5 percent had surgery!

These findings imply that chiropractic care can help you heal from back pain without surgery.

If you live in the New York area, Dr. Phelts can probably help you with your back pain. Give our office a call today at (212) 286-2012 for more information or an appointment.

High Fructose Corn Syrup: Beware

I have counseled many people about healthy eating habits in my Manhattan office.  I have warned against the consumption of high fructose corn syrup (HCFS) in the past and I feel that this topic needs to be revisited, so that it is fresh in your minds. 

A big part of why HCFS is unhealthy is the way that it is processed.  HCFS is made from cornstarch.  Enzymes are added to the glucose in cornstarch to convert it into fructose.  HCFS is cheaper than table sugar, so it is preferred and widely used in the processed food industry

Mercury:  It’s contaminated with mercury.  Mercury is toxic to the central nervous system (brain and spinal cord), kidneys, liver, and immune system.
Zinc:  It depletes the body’s Zinc supply, which is needed to help the body get rid of heavy metals, like mercury, arsenic, aluminum, and cadmium.
Glutaraldehyde:  It contains glutaraldehyde, which is a toxic chemical that contributes to asthma, sneezing, wheezing, burning eyes, drowsiness, headaches, and dizziness.
Liver Disease:  It can cause steatosis aka fatty liver disease.
Diabetes:  Increases risk of developing diabetes.
High Blood Pressure:  Increases risk of hypertension (high blood pressure).  It inhibits endothelial nitric oxide synthase, which is needed to produce nitric oxide.  Nitric oxide relaxes our cardiovascular system.
Cancer:  Increase risk of cancer.  This is especially true of pancreatic cancer.  A 2010 study found that pancreatic cancer cells are able to metabolize fructose and use it to multiply.  This study was written by the American Association of Cancer.
Common Sources of HCFS include:
Soda-  soda is an inefficient way to hydrate yourself, since the sugar content dehydrates you.  Try tea or water instead.  There is a brand called Zevia, which makes carbonated beverages sweetened with stevia.
Salad Dressings- especially the “Fat-Free” options.  Read the label carefully before consuming
Ketchup- for those who love ketchup, look for brands that do not contain HCFS.
Frozen Dinners
Sauces and Condiments
Juice- fruit juice concentrates are considered empty calories, because they lack any significant amount of vitamins and minerals.  They are also high in fructose.  Even products labeled as 100% juice are made with concentrates.  Read the labels carefully.
Coffee Creamers
Energy Drinks
Agave-  That’s right, I said it.  I know that it is touted as a healthy sweetener, but agave syrup contains more fructose than HCFS.  Honey (manuka and buckwheat), Maple Syrup, Molasses, and Stevia are better alternatives.

How To Avoid High Fructose Corn Syrup
The best thing you can do, is to read labels very carefully.  If high fructose corn syrup is found on a label, then you can infer that the item is very poor quality. Eating vegetables and fruits that are fresh or frozen are a better way to satisfy a sweet tooth. Stay away from processed foods that are most likely found within the aisles of the grocery. If you limit your shopping to the perimeter of the store you are most likely shopping where the fresh ingredients are located.

Nutritionally deficient foods can lead to many deficiencies and toxicities which may cause disease and inflammation. It is easy to detect vitamin and mineral status with comprehensive testing. By testing a blood panel to determine where your diet is void of vitamins and minerals, you can quickly make changes to your lifestyle and dietary habits to optimize your level of health.

By discovering what vitamins and minerals you need to supplement with, you can live a life towards optimal health. Dr. Phelts analyzes your blood work and helps get you on the right track with individualized dietary and supplement guidelines based on your test results.  His office is located in New York, NY.

Nutrition Consultation: What To Expect

The purpose of our nutrition protocol is to help you obtain and/or maintain optimal health naturally.  Our services are for those who are looking for an alternative to pharmaceutical medications.  We have found that the health of many of our patients respond very well to specific dietary changes, exercises, vitamins, and certain high-quality herbal and whole food supplements.  Our program utilizes laboratory testing to assess your health and make recommendations.  Many people take supplements, because they heard from someone (most likely on the internet) that it is good for this or that, but they have no idea if it is working for them.  With laboratory testing there is no guessing about which supplements you need.

Before your initial consultation with Dr. Phelts, we send you a symptom survey to fill out.  The symptom survey is a questionnaire that identifies symptoms that are related to the different organs and systems in your body.  After it is reviewed, we schedule your first consultation.  We then order the appropriate blood work and other laboratory tests (like heavy metal and mineral testing), according to the outcome of the consultation.

Once we receive the results of your laboratory tests, we analyze the data and develop a custom treatment plan for you.  The plan may include dietary recommendations, vitamins, whole food and herbal supplements.  The plan may also include physical treatments, such as meridian therapy and applied kinesiology.  Your program is designed to correct any abnormalities, we may have found in your test results.

When we analyze your test results, we use two sets of ranges.  We look at the clinical range, which is the range the medical community uses.  If your values are outside of this range, then you are considered to have a diagnosable disease.  If you have high cholesterol, your medical doctor would diagnose you with hypercholesterolemia and may prescribe cholesterol lowering drugs.  If you have high blood sugar or hemoglobin A1C, then you would be diagnosed with diabetes.  We also look at the optimal range, which is narrower than the clinical range.  If your numbers are outside of this range, then it means that you may be on the way to developing a disease, which of course, we would like to prevent.  Our treatment plans are designed to move you into the optimal range and keep you there.

After you have been on the program for a certain period of time, we retest your laboratory panels.  This allows us to track your progress.  If the results show your numbers are improving, then we know that you are on the right track.  Using the retest results, we can also fine tune your treatment program.

Dr. John Phelts is a certified Professional Applied Kinesiology practitioner and a Science Based Nutrition affiliate.  He practices in New York, NY.  Visits can be in office or by phone. If you would like to learn more about how we help you return to health, gives us a call 212-286-2012.



Avoiding Chronic Pain After an Auto Injury

New York auto injury recoveryApproximately 2.3 million people are hurt each year in car accidents in the U.S. While some people are able to heal from their injuries fairly quickly, many folks are left to deal with chronic pain and impairment. We see many of these patients here in our New York office. Thankfully, Dr. Phelts is here to help you recover from your auto injury.

Is Your Body Trying To Tell You Something?

There is an intimate two-way communication going on between your body and mind that affects both physical and emotional health. The language the body speaks is in the form of symptoms. For example, anticipating an important interview at work can make you anxious: your mind starts racing, your heart beats faster or maybe you get a tension headache. Sure, that headache might just be a headache, related to stress. But what if it's something more?

Having no clear understanding of your symptoms can lead to a depressed mood, making the physical illness even worse. It's important to understand your "body talk."  Dr. John Phelts is a certified applied kinesiologist.  In applied kinesiology (ak), we use unique methods to ask the body question, so that the body can tell you what is wrong and what it needs.

Prolonged, persistent symptoms - physical or emotional - that appear suddenly and affect wellbeing are the body's way of saying something is wrong. Suppressing symptoms hinders the body's ability to communicate what it needs - and more importantly - hides the underlying cause. Many holistic physicians, such as chiropractors, AK, and functional medicine practitioners, are uniquely trained to translate the meaning of symptoms and identify what needs to change in order for health and wellbeing to be restored.

Here are strategies that you can use to help make correlations between the language your body is using and what it means for your health.

Keep a Body-Mind Journal. Record your physical and emotional (feelings and thoughts) experiences upon waking and throughout the day. Do you feel energetic upon waking? What are you thinking and feeling in the moments when you experience physical pain? Another example is a diet diary in which you can assess possible relationships between symptoms, such as headache or stomach issues, and emotions and thoughts associated with what, when and why you eat.

Illness & Lifestyle Inventory. If you're experiencing chronic symptoms, you may need to dig deeper to discover the initial event and triggers that have accumulated over time, resulting in the health problems you're having today. This inventory can include experiences that put you at risk for exposure to toxins (at work, school, an accident); tragic life events; and significant illnesses from childhood, as well as your adult years. Try to pinpoint when symptoms first started, how long they existed before you sought treatment, and what steps have been taken to address symptoms.

Don't Go to Dr. Google. Information on the Web can scare you and easily lead to an incorrect self-diagnosis. Seek the care of a holistic practitioner who can guide you in understanding your body's talk.

Here are some tools that chiropractors, AK, and functional medicine praticioners may use to understand and translate symptoms:

Food Allergy/ Sensitivity Testing: reveals links between health conditions and the food you are eating. By removing foods from the diet that create symptoms, you allow the body to repair and heal, alleviate symptoms, and restore health.

Gut Function Tests: helps determine problems with nutrient absorption.
Nutrient Status Testing: identifies deficiencies that bring about symptoms.

Physical Evaluation: assesses how your body moves, sleep patterns, and mental focusing, which can reveal factors that contribute to the presence and intensity of symptoms.

Laboratory Blood Tests: tells us about key factors in your blood that can indicate the risk of developing and disease or having a disease.  Most conditons can be solved naturally

Ultimately, your body's talk is unlike anyone else's. With careful listening and attentive guidance Dr. Phelts helps you discover the meaning of your symptoms and creates a dialogue with the body and mind that leads to more vibrant health.

Dr. Phelts is located in New York, NY and is here to help people get healthy and stay vibrant.  Give us a call 212-286-2012 to begin your return to great heath.

Enhance Injury Repair With Horsetail

At his New York, NY Office, Dr. John Phelts, D.C. sees many people with injuries, that he successfully helps them to recover from.  He attributes his high success rate in part to recommended the best supplements to help with the healing and repair process.  On of the herbs he prescribes is Horsetail.

Horsetail (Equisetum arvense) is a flowerless plant that contains 5-8% silica and silicon acids. The body uses silica in the production and repair of connective tissue and helps accelerate the healing of broken bones. Silica is also necessary to maintain and repair the nails, hair, skin, eyes and cell walls. You will often find it as an ingredient in hair and skin care products and nutritional supplements. Silica is more abundant in our tissues when we are younger, but declines with age.  

Horsetail is available as a dried herb, often prepared in capsule or infusion form, as well as a liquid extract and tincture. It requires storage in sealed containers away from sunlight and heat. Horsetail contains traces of nicotine and is not recommended for young children. In addition to the Equistetum arvense type of Horsetail, there is another species called Equisetum palustre that is poisonous to horses. To be safe, you should never take that form of horsetail.  We only carry the safest and most potent brands of herbs.

There there are many other medicinal uses for horsetail -- each with unique dosing based on the condition being treated and other individual variables. To ensure the potency and quality of the herb for your health needs, talk with Dr. Phelts.  Call 212-286-2012 and we will be happy to set you up with a consultation.
