Stop Obesity

Introduction

Being obese is not just a problem that is known as “middle age spread’. It has become an alarming condition that affects all age groups, children, adolescents and adults; it has escalated into a health problem that affects a large percentage of the US population. Statistics are hard to ignore: in 2012 one third of adults in the US were overweight. Another third was obese. That means that  two thirds of the population exceeded the upper limit of a normal body weight (a body mass index of less than 25.0). Other countries in the Western world share in the record of being the fattest nations: they are Mexico, New Zealand, Chile, Australia, Canada, The United Kingdom, Ireland and Finland. Not every country with high living standards has high obesity rates. Japan and Korea by comparison have obesity rates of 3 to 4%.

Health consequences

The diseases resulting from obesity as a direct consequence include high blood pressure, cardio-vascular problems (heart attacks and strokes), and type II diabetes. This results in health expenses spiraling upwards. The excessive weight creates additional problems. Not only the heart and blood vessels face an overload, but the joints are also bearing the brunt in the form of joint diseases like arthritis or back pain. These conditions are not fatal, but they account for less productivity at the work place and they create disabilities. In the public sector obesity presents more problems: how can an obese individual be accommodated in a standard airline seat? How can nursing personnel in a hospital manage to lift or transfer a very heavy patient without a mechanical lift?

Obesity can be compared to a snowball that is on a downhill run and if it is not stopped in time, will turn into a deadly avalanche.

Causes of obesity

In the last few years it has become clearer how obesity was created. It originated from the perfect storm that a number of practices of the food industry brought about:

1. Processed food has become more prominent in the super market, laden with salt (creating high blood pressure) and sugar (causing diabetes).

2. Wheat and wheat products are contained in a lot of processed foods, and if they are not in it directly, food manufacturers add MSG (mono sodium glutamate) to stimulate your taste buds. This leads to food addictions encouraging you to eat bigger portions and to eat more sweet, calorie-laden foods.

3. Wheat has undergone forced hybridization in the 1970’s changing the genetic make-up of wheat significantly. The result is much more gliadin, the gooey substance that stimulates your opiate receptors and makes you addicted to food and sweets (Ref. 1).

4. Sugar and high fructose corn syrup are a huge problem for our bodies: sugar consumption in any form leads to overproduction of insulin, insulin resistance and diabetes. 10 to 15 years of life can be lost from premature death due to sugar overconsumption. The causes are accelerated hardening of the arteries with premature heart attacks, strokes and kidney damage. Alcohol in its many disguises is also a problem. The body metabolizes it similar to sugar, excess calories from alcoholic drinks are stored as fat.

5. The oils that are now used to produce baked goods are the cheaper omega-6-fatty acid containing oils derived from safflower, sunflower, soybean, cottonseed and canola. The result is a disbalance of the omega-3/omega-6 ratio in our diet, which causes inflammation in our bodies. This in turn causes heart attacks, strokes, arthritis, asthma, inflammatory bowel disease and Alzheimer’s disease (Ref. 2).

6. In the US there are problems with bovine growth hormone in milk and milk products unless you buy organic milk and milk products. This too causes your fat to accumulate as it blocks your own growth hormone receptors. Antibiotic residuals in beef from feedlots also contribute to obesity in humans.

7. Add to this the fact that we have become more sessile, driving cars, watching games rather than playing games, watching TV and sitting in front of the computer for hours on end. All this burns up less calories than if you work out in a gym.

Knowing the enemy helps us to fight the causes of obesity. Here is my recipe to counter what the agro industry has been doing to us.

What can be done to stop obesity?

1. The biggest factor is to cut out genetically modified wheat that is now the only source of wheat around the world. When you cut out all wheat and wheat products from your diet, you will lose 400 calories every day. Ref. 1 describes this in detail and provides 150 recipes of tasty foods. Dr. Davis allows you a fair amount of monounsaturated fatty acids, which makes dieting a lot easier and you will find that once you have lost the necessary pounds, you will keep your weight down easily. How come I know? Because I have done this myself since 2001. Why does it work? Because gliadin from wheat is an addictive protein that stimulates your opiate receptors in the brain and makes you want to eat more wheat and wheat products, which means taking in more and more calories (Ref.1). It also stimulates your taste buds to eat more sugar and starchy foods. So you need to cut out wheat.

2. Next you need to look at the glycemic index of your foods. Low and medium glycemic foods are OK to eat, but not the high glycemic index foods. It is clear from this link that white bread, pasta, rice, low-fiber cereals and baked goods are not desirable, because they are high glycemic on the index. On the other hand fruit, vegetables and legumes are desirable food choices, as they are low glycemic index foods. Legumes are higher in their carbohydrate content, and a helping of ca. ½ a cup should not be exceeded. Fruit that are high in fruit sugar (grapes, pineapple, mangoes, papayas, bananas) should be consumed in moderation. Fruit juices present an overload of sugar; just remember that it takes several apples to make one serving of apple juice! The same goes for alcoholic drinks. It likely is responsible for much of the obesity wave.

3. Perhaps the most important step is to look at the food that goes into your mouth, eliminate all MSG (monosodium glutamate) and then switch to organic food. I remember that 1/3 of the items on the kitchen shelf and in the fridge had to be thrown out when my wife and I first learnt about this in 2001. We studied the food labels of every food item that was in our kitchen. We added the switch to organic food in the last three years, after hearing about it from Suzanne Somers’ books and at several A4M anti-aging conferences in Las Vegas. Take the time to prepare most of your food that you eat yourself at home from natural, organic  ingredients. This way you can avoid sugar and extra salt, which would be present in processed foods.

4. Watch oils and fat when you cook: extra virgin, cold pressed organic olive oil is your best friend when it comes to cooking Mediterranean type food. Lately there is a trend of cooking with coconut oil, but I think this is a marketing hype (if you decide on coconut oil, make sure it is virgin and fresh pressed, not processed).  Ref. 2 explains that it is important to avoid all polyunsaturated oils as they turn rancid and lead to free radicals in your blood and in your fatty organs like the brain. In order to reintroduce the balance between omega-3 and omega-6 fats, it is useful to take 3 capsules or more (up to 6 or 7 per day in persons with arthritis) of a strong, molecularly distilled EPA/DHA  supplement daily that will restore your prostaglandins. This ensures that no inflammatory reactions take place in your tissues preventing heart attacks, strokes, arthritis, asthma, inflammatory bowel disease and Alzheimer’s disease.

Fish has been and still is highly recommended as a good source of omega-3 fatty acids, which is also anti-inflammatory. But, unfortunately it is contaminated with various amounts of mercury wherever you are in the world, so I find it difficult to recommend it as healthy unless you are willing to undergo chelation therapy on an ongoing intermittent basis to remove heavy metals and this method may not be perfect either. Fish like sardines or wild salmon are the better choices. Tuna, swordfish or shark should never be consumed as their toxic load is dangerously high.

5. Finally, a word about reintroducing exercise. As kids we were more active. You may have played games as a youth. What our bodies need at all times is movement, walking, dancing, in short some form of activity every day. The easiest is to work out in a gym for 1 hour every day (30 minutes of aerobics like a treadmill or elliptical for 30 minutes and isometric exercises like working with machines or weights). Add on top of this whatever you can. This stimulates your metabolism, your blood circulation and rebalances your hormones.

Conclusion

Obesity is a national concern and a concern that affects nations internationally. Bear in mind that the food processors and the associated industry is not on a mission to increase the well being of the consumer, but is driven by the motivation to increase profits. In the past bad dietary advice added more injury to this situation, when the science behind diets was not yet developed. But now we know that a low fat high carb diet does not work; instead a balanced fat, low glycemic index diet as in a Mediterranean diet is what is beneficial. The large amounts of sugar that are currently added and consumed in many processed foods have no place in sensible human nutrition. The senseless overfeeding with grain has also presented its results: it has fattened up North America and other nations. We need quality fats (olive oil, omega-3-fatty acids and nuts). Organic food whenever possible is important in order to avoid poisoning ourselves with pesticides, antibiotic residues or bovine growth hormone. Add regular exercise to this and your recipe for treating and preventing obesity is complete.

Healthy Choices Start In Your Brain

You may have seen the CNN heading “Where is self-control in the brain?”  If we want to make any healthy choices in life including sound financial choices, we need a balanced brain that makes the right decisions for us.

Researchers at the Caltech in Pasadena, CA have examined this question in detail using functional MRI scans and found out that there are two loci on the frontal lobe of the brain that control your impulses: the “ventral medial prefrontal cortex” (red in this link) that processes your initial image (like seeing a delicious ice cream cone”) and the “dorsolateral prefrontal cortex”(green in this link), where you decide that this is not healthy for you because it has too much sugar in it. The Caltech researchers found a group of volunteers who were impulsive and made the wrong choice simply based on their taste buds without consideration for their health in general. An equally large group of volunteers was also found who had functional activity in the ventral medial prefrontal cortex and the dorsolateral prefrontal cortex, the latter of which modified the final decision into the healthy choice. The impulsive group made their decision to buy simply with the activation of only the ventral medial prefrontal cortex.

The researchers think that it is this kind of lack of balanced thinking that decides whether we are going to make the right or wrong health choices for ourselves. The sad part is that ultimately, the summation of bad health decisions during life can become the cause of developing dementia, such as Alzheimer’s disease. The good news is that many of the causes of dementia can be avoided, which means that the average person could prevent dementia. I will discuss this in detail here.

Causes of dementia

It is interesting to study patients with various forms of dementia as it is often in the frontal and temporal portions of the brain where brain cells are dying off resulting in impulsive buying, impulsive behavior and lack of recent memory. It is also important to recognize that a number of conditions or factors can cause dementia:

1. Genetic causes

Here is the

There are two types of frontotemporal lobe dementias, a tau-protein positive FTD and a ubiquitin-positive FTD, which has been shown to be due to a deficiency in progranulin. Both of these genetic defects are located on chromosome 17. In Alzheimer’s dementia, which occurs later in life there can be genetic defects at chromosomes 21, 14 or 19. Epigenetic factors like exercise, avoidance of alcohol, and taking omega-3 supplements can even partially prevent or postpone the onset of dementia from genetic causes.

Healthy Choices Start In Your Brain

2. Toxins like alcohol

Another example of how people can get dementia is through the effect that regular alcohol consumption has on our brains and bodies. This image of an MRI scan shows a normal brain for comparison on the left and  the MRI scan of the brain of a chronic alcoholic on the right.  When a chronic alcoholic has severe atrophy of the brain a psychiatric condition, called Korsakoff’s syndrome can occur. This psychotic condition as a result of the brain having been poisoned by regular alcohol intoxication. Essentially the toxic effect of high daily doses of alcohol have shrunk not only the surface of the brain, but also the deeper substance of the brain. The patient is psychotic, has loss of memory and is unable to care for him/herself.

3. Vascular damage to the brain

Strokes can cause vascular dementia that leads to Alzheimer’s disease-like memory loss. This link points out that diseases like hypertension, obesity, diabetes, atrial fibrillation, ischemic heart disease and dyslipidemia all predispose you to possibly get a stroke with subsequent dementia.

4. Traumatic head injuries

In boxers, football players and combat soldiers brain cells can get lost from repetitive head trauma leading to dementia (in this case it is called “dementia pugilistica”).

5. Infectious dementia

HIV in AIDS patients can affect the brain and cause an HIV-associated dementia. Bacterial meningitis and viral meningitis can kill brain cells and cause a form of dementia as well.

6. Immune disorders

We know that MS can go on to develop dementia as a late complication. In MS there are autoantibodies against myelin, the insulation material that surrounds nerve fibers. An important category of immune disorders is autoimmune disease that can cause dementia. The cardiologist, Dr. William Davis, has presented compelling evidence that wheat allergies can cause dementia, but if detected early and treated by a gluten free diet, this clears up the mind and stops further development of dementia (Ref.1 describes wheat allergies causing dementia; a wheat free diet is described in Ref.2).

7. Hormone deficiencies

A classical example is hypothyroidism, which in the past before thyroid medicine was available, often led to dementia. A simple blood test, TSH (thyroid stimulating hormone) can detect whether or not you are hypothyroid. The A4M recommendation for a normal level is below 2 (not below 5 as often reported by official lab value reports).

8. Lack of vitamins

Thiamine (=vitamin B-1) is often missing in alcoholics. If you are missing vitamin B-6 and vitamin B-12 in your diet, this can predispose you to develop dementia as well. Aging people lose a factor from the gastric mucosa (the intrinsic factor) that is essential to absorb vitamin B-12 in the mall bowel, which predisposes them to develop pernicious anemia and dementia. A simple vitamin B-12 injection can prevent this from happening.

9. Too much sugar consumption

Sugar consumption has skyrocketed in the 1900’s and keeps on going up in the new millennium as well. Here is a review that discusses the possibility that Alzheimer’s can be triggered by overconsumption of sugar. The higher the blood sugar levels in diabetics, the higher the risk for developing Alzheimer’s disease. A study in Seattle has confirmed this. High insulin levels are found in type 2 diabetes; they are responsible for making brain cells stimulate the production of the gooey substance amyloid that causes Alzheimer’s disease. The authors of this study showed this to be true both in humans and in animal models.

10. Lifestyle issues like lack of exercise, excessive weight (obesity, being overweight) and poor diet (fast foods) play an enormous role in terms of causation of dementia in addition to the other factors mentioned. On the other hand organic foods Lack of toxins) and a Mediterranean type diet will preserve your brain cells.

Treatment of dementia

At present treatment of dementia is very limited, as we do not have a complete understanding of dementia at this point. The traditional treatment of dementia outlined here will only marginally delay further deterioration of dementia, but ultimately fail. In my opinion this is because the medical profession has been concentrating on fighting the symptoms of dementia rather than the cause.

Given the list of known causes above, I like to give you 6 recommendations that will help you to prevent Alzheimer’s disease and dementia in general.

  1. I would suggest that you cut sugar out of your diet and replace it with stevia. This also includes dates, grapes, bananas; also wheat and wheat products and starchy foods like pasta, potatoes, rice and bread (see Ref. 1 and 2 for details). The manufacturers of soda drinks, pies and cakes will not be happy about this recommendation, but it will please your brain cells. You will also be surprised how easy it is now to lose weight, which will please you (this also lowers your risk for heart attacks and strokes).
  2. Severely limit your alcohol consumption to less than 1 drink for women and 2 drinks for men per day (better still would be to stay sober) unless you want to become part of the hospital population mentioned in one of the links at the beginning of this blog.
  3. Have your hormones checked, particularly your thyroid hormones, but also estrogen and progesterone levels in women and testosterone in men. Our brain cells have hormone receptors for a reason. They need to be stimulated by our hormones, even in menopause or andropause. Replace the missing sex hormones with bioidentical hormone creams and missing thyroid hormones with thyroid tablets (Armour is the best mix of T3 and T4 thyroid hormones, not Synthroid).
  4. Prevent repetitive brain injuries before it is too late. Rethink whether you really need to box, street fight, play football, rugby or hockey.
  5. Use vitamins for prevention of dementia: The B complex vitamins like B-2, B-6, B-12 (by injection); vitamin D3 has recently been shown to be effective in slowing down Alzheimer’s disease. Vitamin D3 is low in Alzheimer’s patients and vitamin D3 supplements will slow down this disease. Although vitamin C showed equivocal results, it does have some neuroprotective qualities and decreases β-amyloid production and acetyl cholinesterase activity. A Mediterranean-type diet (Ref.2) is also helpful in preventing dementia.
  6. Exercise daily. It will discipline you to stick to the other points mentioned above. It gives you some extra endorphins and will make you feel good about yourself.

Conclusion

Although we do not yet have a complete picture regarding Alzheimer’s disease and dementias, we do know enough to reduce our risk of getting them. When you cut out wheat and wheat products, autoimmune antibodies against your brain cells will not be produced, your opiate receptors in the brain will not be seduced to eat more and more sugar, starchy foods or high fructose corn syrup, so you will have no problem in cutting out high glycemic index foods (Ref.1). This will reduce insulin and reduce IGF-1 growth factors that would have made you vulnerable to produce the gooey amyloid substance that makes you lose your memory. The orbitofrontal part of your brain (particularly the dorsolateral prefrontal cortex) will be reminding you what you read here: healthy lifestyle choices start in your brain.

Allergies Not Only In Spring

Springtime is the time of spring allergies: those affected develop a runny nose, itchy eyes and in more severe cases they may experience a flare-up of asthma. Allergies can be triggered by the increase of pollen counts in the air that occurs every spring. In those who are sensitive, this leads to antibody formation in the blood. But often people have not only sensitivities to the pollens of spring bloomers; they may also be allergic to spores from molds, to dust mites and may have underlying allergies to foods. The immune system has memory cells that memorize that a person has had an allergic encounter to one of these items in the past, and allergic reactions can become more significant with a future encounter. Allergies can also be made worse when a person has food sensitivities and there are cross reactions between pollens of trees or grasses that can share surface protein regions with similar protein regions in foods.

It is known that cross allergies are possible between birch pollen and apple, carrots or hazelnut. In its extreme form allergies due to antibodies, called IgE antibodies, can cause anaphylaxis. A person presensitized by inhaling birch pollen, after eating an apple, hazelnuts or a carrot can develop itching of the throat, swelling of the lips and very quickly deteriorate getting into an anaphylactic shock.

Other cross allergies exist between ragweed pollen, which is a powerful inhalant allergen and melons or bananas. Again there are specific IgE antibodies that are responsible for this immune reaction. In this case the ragweed allergy primes the immune system to produce IgE antibodies, which are potentiated by certain foods that share similar protein components as the ragweed pollen.

In the following I will deal with inhalant allergies separately from food allergies.

Allergies Not Only In Spring

Allergies Not Only In Spring

Inhalant allergies

Inhalant allergies are easier to diagnose and to treat than food allergies. Your doctor will likely refer you to an allergist when you have allergies that do not respond to treatment with intermittent over the counter antihistamines. Your symptoms may come on in the spring with itchy eyes and a runny nose. From year to year you find that you become more and more dependent on antihistamines and nose drops to unplug your nose. The allergist likely will do sensitivity tests, which consist of skin prick or scratch tests on the back or the forearms.

In more serious allergies, where the patient has coughing and wheezing attacks following allergic reactions, the allergist may suggest to start intermittent allergy injections alongside the standard inhalation therapy for asthma. An allergy serum is prescribed where the lab mixes ingredients based on all of the positive tests that led to a strongly positive skin reactions when allergy testing was done. Typically the family doctor or his nurse will start the allergy injections initially in weekly intervals, later when the maintenance dose is reached, it may be modified to injections every 10 to 14 days.

The allergy injections stimulate the immune system to produce harmless competing antibodies, which counteract the disease producing allergic antibodies. In the process of desensitization shots the immune system will normalize, which means that the inflammatory response of the immune system settles down to normal.

This is not the end of the story with inhalant allergies. The patient needs to be retested on a yearly basis by the allergist. The immune system changes all the time as new allergies can develop and old ones may go away.

Retesting is necessary to keep track of what is going on and to change the composition of the allergy serum. Those patients who are working together with the allergist can do very well, and often they gradually outgrow their allergies. Others may not be so lucky. They may have reactions to the allergy injections. In these cases avoidance of what causes the allergy may be the only solution to treat the allergies.

There is an alternative to allergy injections, which has been used in Europe, namely a sublingual immunotherapy. Recently there has been a review of the literature for FDA approval that is needed for oral desensitization for ragweed, dust mites, grass pollen and cat dander. It will take some time before the FDA approval process will become a reality for sublingual desensitization in the US.

A special form of inhalant allergies are allergies to pets (mainly dogs and cats, but also allergies to petting zoo animals). The dander that the human comes in contact with is a protein contained in the animal hair. It causes hives when it touches the skin. This occurs as the dander is absorbed through the skin and meets the local mast cells that release histamine. This in turn is responsible for the hive formation. Sneezing and even asthma can develop from inhaled protein particles that reach the lungs. Allergy injections for the treatment of animal dander allergies are very limited as they often do not help or make the allergies worse. Avoidance of animal contact is usually what the allergist recommends as the solution, a recommendation, which often is not appreciated by the affected animal lover.

Food allergies

Often we eat  some foods more frequently, because they are our favorites. This means that our gut lymphocytes that get in contact with these foods can start to react to one or more of the foods we ingest. At this time we may experience abdominal cramps, diarrhea, vomiting and a host of other possible symptoms.

The physician will tell the patient that testing for food allergies is a problem as most of the usual skin tests employed for inhalant allergies do not reliably work in determining food allergies. The doctor will ask the patient or the mother of the child with food allergies to keep a food diary and keep track of the allergic symptoms in the diary as well. An elimination diet will have to be devised based on the information gathered in the diary as it becomes clear from that record which foods cause which symptoms. The foods causing allergic symptoms are subsequently eliminated. This is a cumbersome process, but it is the most reliable method of testing and treating food allergies.

In the past there was a blood tests, called RAST test, which tested for common food allergies that can cause severe allergic reactions like egg, milk, peanut, tree nuts, wheat, crustacean shellfish and soy. Since about 2010 this has been replaced by the more sensitive ImmunoCAP Specific IgE test.

Children often develop food allergies to egg, milk, wheat, nuts, peanuts and soy, which are food allergies with positive IgE tests. When they age, their immune system develops tolerance to many of these foods and they often outgrow these allergies.

There are other popular lab tests where a blood drop is analyzed with IgG, IgM and IgE antibodies against a panel of foods. A number of suppliers offer these tests.  However, the specificity, sensitivity and reliability can pose problems with regard to the interpretation of the results: allergists often point out that a test may be a false positive when a person likes certain foods and IgG antibodies against this food show up despite the patient having no symptoms. Another specialist may interpret this to indicate that the body shows early sensitization to a certain food, but clinically it is not yet obvious. In other words the sensitivity of the test is so high that it undermines the validity of the test. Recently a panel of international scientists reviewed the validity of these IgG based food intolerance tests and they found the tests not reliable.

The immune responses to food allergies are complicated as there are immediate type immune reactions and delayed type immune reactions. The immediate immune responses are investigated with the above mentioned ImmunoCAP Specific IgE test. The delayed immune responses can be measured using the ELISA test.

Other considerations about allergies

You see from this discussion that a patient with allergies needs a properly trained allergist who will do a comprehensive analysis involving a thorough history, examination, blood tests and immune tests.  The test results have to be interpreted with the experience and the clinical judgment of the specialist.

Since the 1970’s when Clearfield wheat was introduced around the world on a large scale, which has a much higher gliadin (gluten) content than the old wheat varieties. As a result of exposure to this new type of wheat gluten intolerance and leaky gut syndrome have increased substantially in the world population. Genetically modified foods like soy, corn, sugar beets, canola and more have challenged the immune system of sensitive humans even more to an extent, which is not fully understood yet. We do know that some people can develop autoimmune diseases and this may be the reason that a host of diseases that belong into this disease category (MS, rheumatoid arthritis, Hashimoto’s thyroiditis, ankylosing spondylitis etc.) are much more common now than in the past.

After food elimination for 2 to 12 months depending on the severity of the food allergy, your body may have eliminated the allergy to the food you have avoided, in other words your body built up tolerance. Before you expose yourself to any food that you used to be allergic to and that you want to re-test, it is best to have an EpiPen ready in case your allergy has not resolved. Caution is necessary with regard to foods that cause more severe allergies, e.g. shellfish or peanuts, which may last life long. It is safer to avoid these foods that cause more severe allergies altogether.

Allergic reactions of the immune system belong into the category of chronic inflammatory diseases. These are known to be the root of chronic diseases like asthma, arthritis, heart disease, high blood pressure and cancer. When you are vigilant about allergies and get proper assessment and treatment by an allergist, you will prevent serious health problems including the above mentioned chronic diseases.
