Defensive Eating – Protecting Your Brain from the Effects of Monosodium Glutamate (MSG)

Protecting The Brain from the Effects of Neurotoxins

“O is for Occipital Lobe” by Eric on Flickr. Used under Creative Commons license.

Monosodium Glutamate (MSG) is a chemical that food manufacturers add to their products to enhance flavor; it is a cheap way to make very low quality foods taste great. What food manufacturers don’t want us to know is that MSG is a neurotoxin. A neurotoxin is a chemical that has a degenerative effect on the brain and nervous system.

Consumed on a regular basis, MSG creates lesions in the hypothalamus part of the brain.  When this occurs, neurotoxins enter the brain and cause damage. The damage caused results in abnormal development such as obesity, impaired growth, sexual reproductive problems, sleep difficulties and emotional problems.

One source of MSG is derived from fermented sugar beets. Currently, thanks to a company called Monsanto, 90% of sugar beets in the United States today are genetically modified to contain the pesticide gene of Roundup. So, by ingesting MSG we also ingest a known carcinogen.

At first glance, it would seem that removing MSG from our diets would be easy. I mean, just look at the food label, and make sure the product doesn’t list “MSG” or “Monosodium Glutamate” in the ingredients list.  Nothing to it, right? In an ideal world, this would be the case. Unfortunately, if the ingredient is made up of less than 99% MSG, the food manufacturer doesn’t have to list MSG in the ingredients list. MSG can be “hidden” in our foods under more than 50 alternative names and forms including, autolyzed yeast, calcium caseinate, dry milk powder, dry milk protein, gelatin, glutamate, glutamic acid, hydrolyzed corn gluten, hydrolyzed soy protein, hydrolyzed wheat protein, monopotassium glutamate, monosodium glutamate, natrium glutamate, sodium caseinate, textured protein, yeast food, yeast nutrient, etc.

The best way to protect yourself from the neurological effects of MSG is adapt a lifestyle of “clean eating”. Clean eating involves eliminating all processed foods from our diet; a processed food is any food that comes in a bottle, box, bag, can, carton or shrink-wrap, as well as the vast majority of deli and restaurant foods. It is virtually impossible to avoid these foods your entire life; never eating in a restaurant is a somewhat unrealistic expectation in today’s society. So, what can we do to protect ourselves from the neurological effects of MSG when we are in situations where MSG is nearly impossible to avoid?

In 2008, Phytomedicine released a report for a study which explored the use of Red Clover to protect the brain from the effects of MSG. Red Clover contains phytoestrogenic isoflavones which can possibly protect the brain from glutamate toxicity. The study found that by taking Red Clover before consuming MSG, there was a significantly increased cell survival rate and significantly decreased release of cellular lactate dehydrogenase, an indicator of cell damage. You can supplement with Red Clover in a variety of forms (such as teas, tinctures, tablets, capsules, liquid extracts, and extracts), but a whole herb supplement is thought to be the most effective.

Another way to protect our brain from the effects of MSG, is to supplement with Pyruvate. Pyruvate produces energy in the brain. When energy is produced in the brain, the brain is protected against neurotoxicity. Pyruvate is available as a supplement in most health food stores.

Keep in mind, these supplements are good to use when you can’t avoid ingesting MSG. Obviously it is better to avoid MSG altogether, when possible. As I heard a health professional say “it’s like putting a helmet on your head so you can strike yourself with a sledgehammer.”

Hidden Names for MSG

Vitamins and Supplements – Read Your Labels

“I’ve been treating eating disorders (ED’s) and obesity for nearly 25 years and have always had good outcomes.  My rate of success improved dramatically, however, when I discovered the critical role that processed food plays in causing as well as in preventing recovery from Anorexia, Bulimia, Bulimarexia, (a combination of the two) Binge Eating Disorder (BED,) Emotional Eating and Obesity. To this end, I find it of great importance to provide both my patients and readers with relevant nutrition information to aid in their recovery. You can view all my Nutrition, Fitness, and Health articles here.

I recently listened to a podcast that was discussing the drawbacks of prescription-strength vitamins, specifically prenatal vitamins. My first reaction was, this can’t be right. Prenatal vitamins? The vitamins needed at the most critical time for the health of the mother, to say nothing of the health of the unborn child?   I never cease to be amazed at what, we as  Americans will swallow assuming it to be safe.  The claims made by the podcast turned out to be true.   I’ve done my own research; this is what I found for one of the more popular prenatal vitamins:

 Soy lecithin – According to Dr. Kaayla Daniels, author of “The Whole Soy Story”, ingesting soy can lead to:

  • Digestive distress
  • Malnutrition
  • Thyroid dysfunction
  • Cognitive decline
  • Reproductive disorders
  • Infertility
  • Birth defects
  • Immune system breakdown
  • Heart disease
  • Cancer

Hydrogenated Vegetable Oil or “trans fats” have been proven to lead to colon cancer, depression, endometriosis, heart disease and infertility.

Gelatin (and soy lecithin) – Both are sources of monosodium glutamate (MSG). MSG is known to cause:

  • Brain damage
  • Endocrine disorders (obesity and reproductive disorders)
  • Behavior disorders
  • Adverse reactions
  • Neurodegenerative disease
  • Obesity
  • Retinal degeneration
  • Migraine
  • Seizures
  • Cancer
  • Heart irregularities
  • Asthma

Sorbitol – An artificial sweetener that can cause:

  • severe bowel problems
  • diarrhea
  • abdominal pain
  • weight loss,
  • an increase or decrease in urination
  • vomiting, and seizures (in severe cases)

Glycerin – A petroleum product. Petroleum products are obesogens and affect the endocrine system. Studies show obesogens cause stunted growth in children.

Propylene Glycol – A chemical which is also found in anti-freeze. It is suspected to cause:

  • liver damage
  • kidney damage
  • contact dermatitis
  • inhibited skin cell growth
  • nausea, vomiting
  • depression

FD&C blue No.1 – An artificial color, synthesized from petroleum (kind of like ingesting blue crude oil, yum). Studies show this dye can trigger:

  • Learning disabilities
  • Asthma attacks
  • Headaches
  • Nausea
  • Fatigue
  • Nervousness
  • Lack of concentration
  • Cancer

Titanium Dioxide – Tiny pieces of titanium, a chemical that has never been tested for safety for human ingestion. Titanium Dioxide has been linked to:

  • Cancer
  • Allergies and immunotoxicity
  • Organ system toxicity

What You Need to Know In Order to Help Your Obese or ED Patient

Eating Disorder Research

photo used under creative commons license


Research has clearly established a relationship between neurotoxins such as MSG, high fructose corn syrup (HFCS) and sweeteners Splenda and NutraSweet and the current epidemic of obesity. I believe that there is also a relationship between these neurotoxins and the proliferation of eating disorders in the US. For example, research has shown that patients suffering from Anorexia as well as those who are obese, suffer from a condition called leptin resistance.
1 ,2 Further, this condition appears to be a function of the type and amount of neurotoxin ingested. In my practice, when I have helped those suffering from Anorexia, Bulimia, and Bulimarexia and obesity eliminate such neurotoxins from their re-feeding regimens, recovery time has shortened and the likelihood of relapse has decreased significantly. (I am in the process of publishing these anecdotal results and have also applied for several grants to research this relationship experimentally in greater depth.)

Treatment of obesity and eating disorders is negatively impacted for the uninformed treating professional i.e. re-feeding is a nightmare for those suffering from Anorexia, Bulimia, Bulimarexia, Binge Eating Disorder and Obesity when the role of these neurotoxins is not taken into consideration. Thus, to the degree that their impact on the eating habits of individuals suffering from ED’s and obesity is not understood, or worse, ignored, treatment is less likely to succeed, and in many cases, more likely to make the problem worse. For help on refeeding contact me directly. Also check out all of the blog articles on this site. 3

For the past 40 years food additives, known to have neurotoxic effects, especially in children, have been added to the American food supply because they were profitable. These additives include MSG, sweeteners Aspartame and Aceulfame, (Splenda and NutraSweet) growth-enhancing hormones, and pesticides that are incorporated into the DNA of crops like soybeans. The amount of these neurotoxins added to our food has increased enormously since their introduction. For example, since 1948 the amount of MSG doubled every decade. By 1972 over 262,000 metric tons were being added. (Whetsell, 1993)[1] Today it is impossible to determine the actual amounts of the various neurotoxins that are added to the U.S. food supply, as the additives are effectively unregulated by the FDA or any other regulatory agency. As a result, they can be added in ways which make them difficult, if not impossible, to quantify.

Besides being difficult to quantify, the additives are very difficult for the average consumer to identify, as they can be called such innocuous names as “citric acid” “malted barley” and “natural flavoring”! Even for individuals who are well-informed, and therefore know what to look for, it is still a daunting task to try and avoid them. Presently, they are in 90 to 95% of all packaged, bottled, and/or processed foods, including organic and/or foods that are marketed as “healthier” choices.

Perhaps the most alarming issue is that food manufacturers target children’s foods for inclusion of these additives. In the U.S. to day, 1 in 3 children are obese. Many will remain that way for life. We are one of the only countries in the world to have children who suffer from Type II Diabetes, which heretofore has been a disorder of middle adulthood. The connection between childhood obesity and an eating disorder such as Anorexia, for example, is that a history of premorbid obesity increases the risk of the development and decreases the likelihood of recovery from the disorder.

Swimming Into a Cultural Health Crisis

photo used under a creative commons license

Many people would say that we are becoming less and less healthy as a nation because we overindulge. On the surface, this appears to be a safe assumption. At present we have the distinction of being one of the top ten countries in the world for overweight adults! Obesity has reached epidemic proportions in the population at large with a whopping 60% of all adults being overweight and one out of four being morbidly obese. Break out the numbers specifically for the aging Baby Boomers and the stats are even more distressing- practically three out of four mature U.S. adults are classified as overweight or obese. But the worst part is that obesity is increasing at such an alarming rate among U.S. children at present, that they will be the first generation in decades that are projected to have a shorter lifespan than their parents! So the future looks even worse than the present. Eating disorders are also proliferating, affecting new segments of the population that include younger and younger children, as well as older women and men.

The complications of obesity alone have wreaked havoc with our health care system as well as our national economy. For example, “Health care costs related to obesity- which is associated with conditions like hypertension and diabetes- would total $344 billion in 2018, or more than one of every five dollars spent on health care, if the trends continue. If the obesity rate were held to its current level, the country would save nearly $200 billion a year (or $1.4 Trillion) by 2018, according to the study.” (Sack 2008) In terms of Eating Disorder’s, Anorexia alone, kills more women between the ages of 15 and 24 than any other cause of death.

The question is why is this happening? The answer is that if you are a fish, you do not see the water. Because you are immersed in it, you take it for granted. In much the same way, we are immersed in a culture that we assume to be safe. This is our underlying assumption. The fish may remain in polluted water until it becomes so polluted that it is no longer life sustaining. By then, it is too late. Like the fish, we are oblivious to the forces surrounding us. To change our culture, we must first be able to identify the underlying assumptions that are driving the current epidemic of obesity and eating disorders in the U.S. We must each then act to change our lifestyle and advocate for our safety.  Stay tuned for Dr. Norton’s soon to be released book that details the problems, their causes and the solutions.

Is There Really a Connection Between Full-Time Working Moms and Child Obesity?

photo used under creative common license

Over the past 35 years, the percentage of U.S. mothers who hold down a job while raising kids have soared from less than 50% to more than 70%. During this same time frame, the childhood obesity rate-which is now close to 17%- has more than tripled. Many researchers are claiming that there’s a direct connection between these two figures. The journal of Childhood Development just published a study, which showed that the longer a mother is employed, the more likely her children are to be overweight or obese. The study demonstrated that for each additional five-month period that his or her mother is employed, a child of average height could be expected to gain 1 extra pound over and above normal growth. In addition, six graders with working mothers were found to be six times more likely than those with stay-at-home moms to be overweight.

Another study published in Business Week supports this same concept, finding that was a correlation between the number of hours a women works outside the home and the BMI of her children. This research found that for a third grader of average height, the increase in BMI was equivalent to an extra one and a half to two extra pounds over what that child would normally gain in a year.

With studies like these being done, the idea that American kids are getting fat because women work outside the home now, could seem convincing. But hold on. These are correlative studies, not experimental research. The problem with these conclusions is that there may be several other things occurring simultaneously “causing” or contributing to this dietary epidemic.

Obviously, if women are spending long hours at work, as many do, home cooked meals are less of an option. In our nation it has become far too common for the wife to pop something pre packaged into the oven at night or pick up a pizza on her way home in order to accommodate her family with a meal that is quick and tasty.

The issue is that convenience foods have become a way of life for Americans. The ability to buy ready-made food is so much the norm that cooking for yourself seems like overkill, like you’re trying to win the best mom ever trophy. When push comes to shove, and it often does, most moms say the heck with it! Bring on the pizza. But that’s when the real problem kicks in, as processed foods are loaded with MSG, HFCS, Aspartame and Acesulfame, all of which are neurotoxins and all of which contribute to weight gain or disturbed eating. It doesn’t matter if the wife had the WHOLE DAY to cook a meal anymore because she wouldn’t anyway. Not when she can just run down the street to KFC and have a bucket of chicken in less than 10 minutes.

Thus it is the additives in these convenience foods that are directly responsible for why our nation and our children have become so fat. The percentage of mothers working full time may have gone up over the past 35 years, but so has the amount of MSG and high fructose corn syrup being poured into the foods we buy. They are found in just about all prepackaged, frozen and fast foods. They keep our stomachs saying “yum!” and “more,” and our blood sugar levels on a constant rollercoaster.  Working mothers who have jobs don’t directly cause weight problems in their children. Reliance on and trust in processed foods containing dangerous addictive additives should be getting blamed. Unfortunately, most people don’t even know they’re there!

The Connection Between Leptin Levels and Eating Disorders

Leptin

image used under a creative commons license

Recently the Division of Endocrinology at the University of Kentucky College of Medicine performed a study on the connection between Leptin levels and eating disorders. Leptin is a peptide hormone neurotransmitter produced by fat cells and involved in the regulation of appetite. It signals your brain when you’ve eaten enough and stimulates you to burn more calories. In order to span a full range of human body weights for their investigation, the analysts, examined serum leptin levels in anorexic, bulimic, obese, and control individuals.

Compared to the analysis generated from non-anorexic patients, patients with anorexia nervosa were found to have much higher serum leptin levels values. In effect, having leptin levels so high is contributory to a blunted physiologic response to being underweight and consequently builds resistance to dietary treatment. Simply put, they have too many of these leptin hormones being sent to the brain that are saying, “You are full.” Therefore, anorexic patients repel the need to consume enough of the nutrients their body realistically needs to function properly.

On the other hand, what this study found in bulimic patients when compared to non-bulimic patients is the opposite effect. Bulimic patients were found to have much lower leptin levels. This deficiency of leptin hormones is usually caused by a form of Leptin resistance and this contributes to the patients food-craving behavior. The Leptin resistance found in most bulimic patients comes from a chemical surge located in the pleasure center of our brain. This chemical surge overrules leptin’s messages that are trying to tell the bulimic patient “your tank is full.” So in other words, there is a chemical battle going on inside a bulimic patients brain. The leptin hormones are trying to tell the defense to kick in and protect them against overeating but at the same time, in a much louder voice, the pleasure center of the brain is saying, “No! Pass those cookies this-a-way.”

When examining leptin levels in most obese people, it was found that they actually have high leptin levels. However, their bodies usually cannot respond to these leptin hormones because they have another form of leptin resistance. Instead of leptin messages being rejected and overruled by the pleasure center of the brain (like the type of resistance indicated in most bulimic patients), obese patients cells’ have completely stopped accepting leptin messages all together. Therefore, they do not receive any message from their leptin hormones that would be telling them to stop eating.

Essentially, regulating your leptin levels and defeating leptin resistance plays a large role in overcoming an eating disorder. Foods that are high in sugar or additives such as high fructose corn syrup and MSG should be avoided because these ingredients excited the pleasure center of your brain making it much more difficult to respond to your leptin hormones. So basically, the more foods you consume with these ingredients, the louder the voice saying, “Pass those cookies this-a-way,” will become and the softer the voice saying, “You are full!” will become. Also, your cells become more sensitive and responsive to leptin when you exercise and build muscle!
