Sugary soda is extra bad for you, say experts

While calories from any food have the potential to increase the risk of obesity and other cardiometabolic diseases, 22 nutrition researchers agree that sugar-sweetened beverages play a unique role in chronic health problems.

The disease risk increases even when the beverages are consumed within diets that do not result in weight gain, the researchers say.

It’s just one of the conclusions published in Obesity Reviews in a position paper by a group of researchers who participated in the 2017 CrossFit Foundation Academic Conference.

The task of researchers was to deliberate the question: Are all calories equal with regards to effects on cardiometabolic disease and obesity? The paper provides an extensive review of the current science on diets that can lead to obesity, cardiovascular disease, and type 2 diabetes.

The paper’s sugar-sweetened beverage consensus is particularly relevant in light of a recent legal battle over warning labels on soda, which hinged on the 9th Circuit Court’s determination of whether soda and other sweetened beverages are uniquely harmful to human health or one source of calories among many.

“What’s new is that this is an impressive group of scientists with vast experience in nutrition and metabolism agreeing with the conclusion that sugar-sweetened beverages increase cardiometabolic risk factors compared to equal amounts of starch,” says lead author Kimber Stanhope, a research nutritional biologist with the School of Veterinary Medicine at the University of California, Davis.

Another interesting point of consensus among researchers is the role of the sugar substitute aspartame. The authors agreed that aspartame does not promote weight gain in adults. Stanhope says this might come as a surprise to most people.

“If you go on the internet and look up aspartame, the layperson would be convinced that aspartame is going to make them fat, but it’s not,” says Stanhope. “The long and short of it is that no human studies on noncaloric sweeteners show weight gain.”

The authors also agree that consumption of polyunsaturated (n-6) fats, such as those found in some vegetable oils, seeds, and nuts, lowers disease risk when compared with equal amounts of saturated fats. However, that conclusion comes with a caveat. Dairy foods such as cheese and yogurts, which can be high in saturated fats, have been associated with reduced cardiometabolic risk.

The paper reviews the significant challenges involved in conducting and interpreting nutrition research. “We have a long way to go to get precise answers on a lot of different nutrition issues,” says Stanhope. “Nevertheless, we all agree that a healthy diet pattern consisting of minimally processed whole grains, fruit, vegetables, and healthy fats promotes health compared with the refined and palatable typical Western diet pattern.”

Additional authors include researchers from UC Davis, who were part of an international team of researchers from 11 different institutions.

Eat early, fast late in day to improve blood sugar control, blood pressure

A pilot study conducted at LSU’s Pennington Biomedical Research Center sh
ows that eating all your meals by midafternoon and fasting the rest of the day improves blood sugar control, blood pressure and oxidative stress, even when people don’t change what they eat.

“Ours is the first study in humans that shows consuming all of your calories in a six-hour period provides metabolic advantages compared to eating the exact same amount over 12 hours or more, even if you don’t lose weight,” said study co-author Dr. Eric Ravussin, Pennington’s associate executive director and director of the Nutrition Obesity Research Center. “Our data also indicate that our feeding regimen has to be synchronized with the body’s circadian rhythm and our biological clock.”

The research is important, Ravussin said, because it shows for the first time in humans that the benefits of intermittent fasting are not solely due to eating less. Practicing intermittent fasting has intrinsic benefits regardless of what you eat, he said. Also, the study shows that eating early in the day may be a particularly beneficial form of intermittent fasting.

Dr. Courtney Peterson, primary investigator on the study, said she hopes the research also will raise awareness of the role of the body’s internal biological clock — called the circadian system — in health.

“If you eat late at night, it’s bad for your metabolism,” Peterson said. “Our bodies are optimized to do certain things at certain times of the day, and eating in sync with our circadian rhythms seems to improve our health in multiple ways. For instance, our body’s ability to keep our blood sugar under control is better in the morning than it is in the afternoon and the evening, so it makes sense to eat most of our food in the morning and early afternoon.”

Previous studies showed intermittent fasting improves metabolism and health. However, researchers didn’t know whether these effects are simply because people ate less and lost weight.

In the Pennington study, eight men with prediabetes followed both the intermittent fasting diet and eating at typical American meal times for five weeks each.

On the restricted schedule, the men each started breakfast between 6:30 a.m. and 8:30 a.m. and finished eating for the day six hours later. They then fasted for the rest of the day — about 18 hours. Everyone finished dinner no later than 3 p.m.

By contrast, on the typical American schedule, the men ate their meals spread across a 12-hour period. They ate the same foods on each schedule, and the researchers carefully monitored them to make sure that they ate at the correct times and only ate the food that the researchers gave them.

The researchers found that the fasting diet improved insulin sensitivity, which reflects how quickly cells can take up blood sugar, and it also improved the ability of the men’s pancreases to respond to rising blood sugar levels. The researchers also found that the blood pressure of the men was dramatically lowered, as well as their oxidative stress levels and their appetite levels in the evening.

These findings, the researches said, could lead to better ways to help prevent type 2 diabetes and hypertension.

Ravussin is a world-renowned expert in the conduct of translational research in obesity and type 2 diabetes. Over his more than 30-year career, he has conducted numerous clinical investigations on measures of energy expenditure, body composition, carbohydrate metabolism and biomarkers of aging in health and disease states.

Peterson is an adjunct assistant professor at Pennington and an assistant professor at the University of Alabama at Birmingham. The study will be published in the journal Cell Metabolism.

Fibromyalgia Treatment

fibromyalgia treatment scottsdale azFibromyalgia Treatment

Fibromyalgia treatment is complicated.  Why is it complicated? Because no two people experience fibromyalgia the same.  The symptoms of fibromyalgia can vary greatly and even the diagnosis is one of my least favorites because it doesn’t tell you what exactly is going on in your body, but rather simply that you have a lot of symptoms going on with widespread pain being the most common or problematic.  In fact there is no real lab test that is considered widely accepted, the most accepted diagnosis criteria is simply your doctors opinion.

Given the diagnosis is based on the opinion of your doctor, depending on your doctor’s predisposition and experience they will have different outlooks.  If your doctor has never treated a case of fibromyalgia that resolved, then they would have zero hope for you, while if your doctor has a high success rate treating patients with fibromyalgia, the path may look difficult but doable. Fibromyalgia treatment in conventional medicine is primarily comprised of management of symptoms by use of prescription pain relievers and antidepressants.  If that is not what you want, then it’s time to look at a more holistic view of treatment options.

The holistic view of fibromyalgia treatments is a multi-faceted approach where many things are considered. It almost always requires lifestyle changes but the upside is that many peoples’ pain levels decrease rapidly.

What are some of the major factor to address when treating fibromyalgia?

1 – Food Sensitivities

In this category the first major food that should be avoided is gluten.  Gluten is known to be associated with many conditions, but one of the more common presentations is neurological pain. In fibromyalgia one of the common tenets is excessive sensitivity to pain.  Meaning what is not painful to someone else is very painful to you.  Other major food sensitivities include solanines (nightshades), albumin (egg whites), casein (dairy), caffeine and its derivatives, and zein (corn).  Having a sensitivity to any one of these foods can lead you to experiencing chronic pain and increased sensations due to inflammation.

2 – Fungal Overgrowth

Candida is the most commonly known fungal overgrowth.  It can go undetected for years or even decades in many individuals.  Fungi release toxic substances called mycotoxins that create things like brain fog, fatigue and bloating.  According to the National Institute of Health, mycotoxins “are secondary metabolites produced by microfungi that are capable of causing disease and death in humans and other animals.”  In the patient population of fibromyalgia, my experience suggests that nearly all patients have or will develop a fungal infection.  This may be in conjunction with a depressed immune system or may be a result of antibiotic use, but it is something that should be ruled out.

The other place that fungus often occurs that people are unaware of is in your own home.  Mold or fungus from water leaks can be the reason many people never recover.  As people get sicker, they stay inside their house more often and the house can make them continually progress in a downward spiral.  House mold can also be the reason why people often find that they get sick when moving to a new house.  If the previous owners had a leak and didn’t remediate properly it can plague you for years without ever being discovered.  I find that clinically people often suffer from psychological symptoms ranging from anxiety to hallucinations and feelings of gloominess at night when exposed to fungus.

3 – Thyroid Disorders

If you haven’t ever been checked for thyroid disorders, with pain and fatigue it is a good place to start.  The catch is that standard thyroid treatment is simply recommending thyroid medication.  In my opinion, this is not the ideal way to treat the thyroid.  Without going into too much detail, the thyroid more frequently a result of other more root level causes that have gone wrong.

Digestive disturbances, allergies (gluten, dairy, corn), estrogen dominance, heavy metal toxicity, etc. definitely need to be looked into before simply taking a medication.  Even when medication is required, these root level causes should be addressed in addition to the medication.  Not looking for root level causes is one of the reasons why many people have lab tests that show a need for thyroid hormone and yet when they take it they feel the same or sometimes worse.

4 – Vitamin & Nutrient Deficiencies

As diseases progress, vitamins and nutrients get depleted.  Magnesium, B complexes and Vitamin D are all common deficiencies, but no different than a drug, we need to find out why you are depleted in certain vitamins and/or minerals in the first place. Magnesium is most commonly needed due to blood sugar imbalances, activated B complexes are often required due to allergies/histamine and vitamin D is often low due to kidney and liver function issues.

5 – Dysbiosis, Leaky Gut and SIBO

Lab testing for leaky gut, SIBO and other gut health issues is still in its infancy.  Most patients that present to my office have had false negatives in lab testing.  Meaning it came back negative, but it shouldn’t have because there really is an infectious component.  There are tests that can discover some variations of each of these conditions, but it is important to know with lab testing that you can only find what you are looking for.

My other most common patient presentation is someone that has tested positive for gut infection but that hasn’t used the right natural remedy.  Gut health can change rapidly and which natural remedy you take can change from week to week. This is one reason why having an astute practitioner educated in all virus, parasite, bacterial and fungal infections is important to resolving deep rooted health problems.

6 – Heavy Metal Toxicity

Heavy metal exposure and eventually toxicity is more common than most believe.  As the body is overloaded with other toxins like plastics, PCBs, GMO foods, dyes, chemical inhalants, etc. the liver and kidneys get overburdened and are unable to detoxify all of the heavy metals that one is exposed to.  Dental work often releases heavy metals in to the body that had been stored previously in tooth and bone.  The parotid glands in the mouth play a major role in the detoxification of heavy metals.

7 – Adrenal Dysfunction

I find that the most common stressor to the adrenal glands is a hidden food allergy.  This is one of the main reasons why so many people respond well to the paleo diet or any other elimination diet. All of the above mentioned factors can also stress the adrenals and lead to chronic pain. Once chronic pain has set in, that also can put stress on the adrenals.  It is a viscous circle that has to be stopped by finding out the stressor to the adrenals and then supporting the adrenals while you persistently avoid the stressor over time.  When you have a stressor to your body for extended periods of time, this leads to high cortisol levels.  Often times you may notice gradual weight gain due to a constant stressor to your body.  Abdominal weight gain is highly correlated with adrenal dysfunction.

Conclusion

There never is a simple route to recovery when dealing with fibromyalgia but by dedicating yourself to a healthy lifestyle that focuses on avoiding triggers you stand the best chance of recovery.  Traditional medicine is only going to mask your pain and drug you for the unforeseeable future, so its not really the best option.

By finding a holistic practitioner, meaning someone that addresses all root causes, you can often start to notice changes rapidly.  Please contact me if you need help or if you are looking for a qualified practitioner in your area.

Toxic Belly Fat and Stubborn Weight Loss

Lymphatic Toxic Fat cellsYour Toxic Belly Fat!

Think that last inch or two (or 10) of belly fat is harmless?  You eat “healthy and organic” yet you don’t seem to lose much weight?  One of the reasons so many people struggle with belly fat is because it is actually a temporary protective mechanism against disease.  You may find that you get fatter as you age and that the weight is harder to come off, but guess what? That actually may be a good thing for a little while!

The catch is that you have to figure out what is going on and fix it before you gain continuous weight and get a chronic disease.

The Body’s Compensation Mechanism

When the liver gets overburdened with toxins and hormones it pushes the fat-soluble toxins out into the blood stream.  (Yes, now you have poison in your blood stream) The fat-soluble toxins then go throughout the body until they run into a fatty cell that can absorb them.  Abdominal fat is one of the closest areas with a large amount of fat cells, but the brain is another large repertoire of fat cells that the toxins can deposit into.

One of the side effects of losing weight rapidly is that you end up with toxins recirculating in the blood stream.  As you lose your belly fat, you slowly but surely release toxins into your blood stream and often people feel awful.

If you have ever started losing weight and then hit a plateau, this can often be because you are still overburdened with toxins that they body is either trying to keep stored or as you lose some it continues to create more to protect you from the toxins.

Toxic Exposure

If there is one thing we can do as individuals to improve our health and lose weight it is to avoid toxins. Toxic exposure to things like plastic (all plastics), hormones & hormone replacement therapy, makeup, lotions, creams, pesticides, heavy metals, car exhaust, processed food, soft drinks, city water, food additives, GMO foods, hormone laden meat, most cleaning chemicals and even perfumes leads us to a lifetime of sickness and “unexplained” disease.

In an ideal world your body would be able to detoxify all of the toxins and they would pass through the body, but given the huge increase in exposure, the new chemicals and the modern “franken-foods” that we are creating each day, belly fat and toxin load is accumulating in many people.  The load on the liver, kidney and other detox organs is becoming overwhelming.

What Can You Do?

  1. The first thing to do is avoid as many toxins as you can. You will need minimal toxic exposure as you try and release all your toxic fat cells.
  2. Slowly increase your dietary fiber and eat lots of greens and beets. Beets help to thin the bile.  The bile combined with dietary fiber helps to bind toxins and then push them out the other end.
  3. Lose weight. Once your system is clean, then you can begin lose weight rapidly to release the toxins from storage. If you reach a plateau, then focus on more detoxification and you will often see that the weight loss from a healthy diet restarts itself.
  4. Undertake a healthy detoxification program with a qualified practitioner

Allergies: Beyond Skin (and Nose) Deep

Sneezing, Sniffing and Scratching? Allergies Blow!

Does your dog send you into a sneezing frenzy? Do certain foods leave you bloated and headachy? Or do pollen’s and certain grasses leave your skin desperately itchy? If you answered yes, then you know this is a daily reality for you and the millions of people living with allergic conditions such as hay fever, asthma, food allergies and eczema.

So why does your body react this way? Essentially, your body believes that these otherwise harmless substances (animal hair, foods and grasses) are threatening. Hence, when it comes into contact with these substances, known as allergens, your immune system releases large amounts of the chemical histamine. Histamine is like a burly bouncer outside a club: its job is to muscle an allergen out of your body by any means necessary. Some of the ways histamine does this job is by producing redness and inflammation, a running nose, itchy eyes, constricted airways, bloating and diarrhoea; manifestations of allergic disease.

Allergies are Like Onions, They Have Layers

Current approaches to allergy management centre on both allergen avoidance and reducing histamine (e.g. antihistamine medication). But why does your body think these substances are harmful and mount this response against them in the first place? Several contributing factors lead your body’s immune system to respond this way, including:

*Inflammation within your digestive tract (where the majority of your immune system is found).
*Damage to the lining of your digestive tract commonly known as ‘leaky gut’, allowing small particles (undigested food, bacteria and/or toxins) to pass through to the blood
stream causing inflammation in other areas of the body).
*Low levels of good bacteria and/or an overgrowth of bad bacteria within your intestine that interferes with your body’s immune response.

Addressing the Roots of Your Reactivity
Truly holistic allergy management encompasses symptomatic relief while also retraining the body’s immune system to tolerate ‘threatening’ allergens. One way you can achieve this is by following an Allergy and Reactivity Reduction Program. This specially designed and professionally supported program incorporates carefully selected herbs and nutrients combined with tailored diet and lifestyle recommendations; to help repair your gut, improve your ability to tolerate allergens, and reduce your reactive symptoms.

A Tolerable Diet
Following a prescribed diet in conjunction with specialised supplementation greatly assists in reducing symptoms and building tolerance to allergens. Your Practitioner will recommend a specific dietary plan depending on your symptom presentation and health history. While following the Allergy and Reactivity Reduction Program you will ‘rest’ from foods that may be creating inflammation and damage within your gut, giving your immune system an opportunity to ‘reset’ and become more tolerant. Your Practitioner may also work with you to strategically re-test the foods you have been ‘resting’ from to determine the right amount for you in the future; so you can
remain symptom free, while still enjoying the foods and activities you love.

Time to Breathe Easy
Now is the time to address those irritating allergic symptoms by tackling the underlying causes. Completing this program can help you gain control of your reactivity and increase your tolerance levels, leading to a reduction in symptoms. Imagine indulging in the foods and activities you enjoy; patting your dog without sneezing, eating the foods you love without bloating, or having a picnic in the grass without itching – now that would be life changing!
