Eat more and more, do you know chemicals in foods blow you appetite?

In a very real sense, everybody has direct reactions to foods. Direct reactions are reactions caused directly to cells by chemicals in foods. Among the most obvious direct reactions are those caused by alcohol. If you drink alcohol, you are almost certain to experience sedative effects, due to the direct effect of alcohol on your brain cells.

Often, people with Asian heritage react quite negatively to alcohol, and the common belief is that they're allergic to it. Technically, though, they don't have an allergy; they have a sensitivity — because this is a direct reaction, which doesn't involve the immune system. I believe that it's clearer and more sensible to say simply that Asians often have a food reaction to alcohol, since food reactions include both allergies and sensitivities.

Direct reactions, however, can eventually involve the immune system, because sooner or later the immune system is called in to repair the mess that direct food reactions cause. Therefore, the symptoms of direct reactions can feel much like allergies. Because of this, direct food reactions are sometimes called false food allergies.

Alcohol has obvious direct actions, but most direct food reactions are more subtle. Often, direct reactions occur when chemicals in foods bind with the cells that produce histamine; these cells are called mast cells. When this happens, it can cause the release of histamine. The food chemicals that are most likely to do this are lectins, which are most often found in wheat, peanuts, and beans. Another cause can be certain partial proteins, or peptides, that are found in tomatoes, strawberries, shellfish, pork, chocolate, and eggs.

Other foods that often seem to cause direct food reactions are mustard, pineapple, papaya, buckwheat, and sunflower seeds. Ironically, one patient of mine had terrible digestive symptoms, including severe heartburn, and took large amounts of digestive enzymes to help the problem. However, his enzymes were full of papaya, which he later found he was reactive to. When he stopped taking the digestive aids, his digestion improved immeasurably. Moral of the story: don't trust common knowledge about what's healthy — trust your own experiences. Everyone is different.

Other foods that sometimes cause direct reactions are those that contain high levels of natural histamines. Histamines are formed in foods that are allowed to age and ferment. Therefore, histamines are often found in aged cheese, sausage, and salami.

Other foods that can cause direct reactions are those that contain the partial proteins tyramine, phenylethylamine, and octopamine. These chemicals, like histamines, can cause blood vessels to expand and contract, which causes tissue swelling. In the head, blood vessel constriction and expansion can cause migraine headaches. That's why people who get migraines often shun the foods that are high in these partial proteins, such as wine, aged cheese, citrus fruit and yeast.

Another common foodstuff that often causes direct reactions is the artificial sweetener aspartame. Aspartame is mostly composed of the partial protein, or amino acid, called phenylalanine. In some people, it acts directly on brain cells, causing symptoms such as agitation and depression. In other people, it causes blood vessels to contract and expand, triggering migraines. In most people, though, it causes no reaction at all.

Many people also react to MSG, or monosodium glutamate, with headaches, nausea, dizziness, heart palpitations, and confusion. Others react to various additives, including nitrates, sulphites, and artificial food colours.

Another name for direct food reactions is pharmacologic reactions. That's a good description, because it implies an important point: foods, like drugs, are chemicals. Not all drugs are good for you — and not all foods are, either.

Now let's look at the last type of food reaction: immune complex reactions. This type of reaction is not well known. But it should be. It can be a killer.

Foods, like drugs, are chemicals. Not all drugs are good for you, and not all foods are, either.

Chronic Illnesses and Diet part 3

Visualization and Chronic Disease

To the ten steps of the Body Clock Prescription, I'd suggest adding visualization, another powerful tool for controlling chronic disease. Life consists of moving forward into images. You get to the dry cleaners to pick up your laundry by making a mental picture of the journey and moving forward into that picture. No picture, no laundry. With visualization, you are going to create an inner picture in order to realize your intention, not just in the outside world of the dry cleaner but in the inside world of your immune system.

The first step is to get the knack of meditation so that your mind and body are in a receptive posture for visualization. Let's assume that you've learned to enter a meditative state; riding on the letter M, your mind can enter a new space within your consciousness. From here, you can take one step forward into your imagination and make a picture of what you want to accomplish in your body.

The effectiveness of this approach was initially proven in an experiment conducted with doctors suffering from terminal or advanced cancer. They were shown accurate images of their own cancer cells and of their immune system cells and were asked to create a realistic visualization of the immune system cells attacking the cancer cells. Most of the doctors successfully curbed their cancer — not to the extent of actually curing it, but in most cases there was measurable improvement. Since then, numerous experiments have shown that a less accurate image of the enemy is just as effective.2

Diet Start

About twenty years ago I used to meet one evening every month with a group of other doctors, including Dr. Bernie Siegel, one of the pioneers of visualization. Bernie shared fascinating examples of the kinds of imagery cancer patients chose to promote healing of their illnesses. It seemed important that the image be accurate in its intent; it was disconcerting when patients chose wimpy defensive images that were the imaginary equivalent of trying to beat their cancer with a wet noodle. People who chose aggressive images did better; lions, tigers, sharks, polar bears and knights in shining armor do better work than a little girl gathering up cancer cells into snowballs and throwing them over the fence.

But what's a good image if you have chronic inflammatory disease? In this case, redness, heat, swelling and pain afflict some part of your body as it reacts to an enemy that the doctor hasn't been able to discover or that has disappeared from the scene of the crime, leaving your immune system in a perpetual dither. You need a picture that is soothing but not self-defeating by way of quieting your immune reactions to the point of defenselessness. This is where a chemical or an abstract image may be more appropriate. By chemical image, I mean something along the lines of `Let's put out the fire'. Remember that inflammation is an expression of your body's fire burning out of control. Whether it is in the skin, the digestive tract, the lungs, the heart, the nose or the eyes or, for that matter, whether or not it is producing palpable heat, some kind of uncontrolled fire is at the bottom of a lot of chronic illness. Parkinson's disease, for example, has been characterized as a fire in the brain. And the oxidative damage in the chemistry of autistic children constitutes a kind of fiery injury to their RNA and DNA.

If you are going to employ visual imagery to quench the fire, then why not use pictures that are more effective than merely aiming a fire hose or throwing ice water at it? Instead, try mobilizing your body's powerful natural resources for quenching the inflammation, calling on your body's clouds to release rainwater on the brush fires of the prairie where the inflammation resides. This could be your intestine if you have colitis, your joints if you have arthritis, your skin if you have dermatitis, your lungs if you have bronchitis and so on. You can even get technical and make your raindrops into vitamin C, vitamin E, beta-carotene and other potent antioxidants. Communication between your meditating-visualizing brain and the resources of your body is more dynamic and more specific then you know.

When Bernie Siegel began talking about people's responsibility for their own health and healing in the face of serious illnesses such as cancer, people accused him of 'blaming the victim' by placing an unreasonable burden of guilt on the sick person. But you can't really take control of your health without believing that your health is to some extent under your control. Even a person who has been a victim of some catastrophic accident must believe that he or she can exercise control over healing, to at least a small but critical degree, through the expression of intention in prayer or visualization or by the exercise of sheer willpower.

For people with chronic illness, the lines of causation are more ambiguous than they are in an accident. However irrational it may be, all of us feel guilt for things that happen, like the ill-timed flareup of cold sores just before an important public appearance. Feeling guilty won't get you anywhere, but feeling responsible is the key to taking charge. If you feel like you're the passive victim of the event, you may miss a chance to engage your body's resources for healing. Only by feeling that you can take responsibility for your own health will you be able to make the changes that are necessary for regaining that health in the face of chronic illness.

The Vital Acid—Alkaline Balance continue...

Excess salt intake can also severely upset the body's water balance. Along with potassium, which also occurs naturally in fresh foods, the sodium in foods and in salt itself (which is sodium chloride) plays an important part in the movement of electrons through the body's water- based protoplasm. This is why sodium and potassium are known as electrolytes. Potassium tends to concentrate in the cells, sodium in the fluids outside the cells. The balance between sodium and potassium, when it is right, sets up a dynamic tension that makes it possible for the living cells to react quickly and efficiently to nerve stimuli, to exchange nutrients and wastes easily through the cell wall, and to maintain the proper interior and extracellular water balance. Too much sodium, which most of us get from eating salt, upsets this balance altogether and can cause troubles. It forces the body to hold on to extra amounts of water to make up for the extra salt one has eaten. Tissues become bloated, and this salt-caused edema can interfere with the blood's oxygen transfer to cells as well as creating extra pressure against the blood vessel walls themselves. These are some of the reasons the Lifestyle Diet eliminates salt both in cooking and at the table. It relies instead on fresh and dried herbs, garlic, and spices for seasoning.

Throw out the Coffee

Caffeine, a trimethylated xanthine, is found in coffee beans, tea leaves, cola nuts, and cacao, from which chocolate is made. Together with nicotine and alcohol, it makes up a trio of the most widely used psychoactive drugs in the world. The xanthines are stimulants to the central nervous system. They increase heartbeat rate, increase the volume and concentration of acid in the stomach, relax the smooth muscles in the body, raise blood lipids, stimulate the cerebral cortex (which means they heighten the intensity of mental processes), banishing drowsiness and feelings of fatigue. Caffeine and alcohol also have a diuretic effect on the system, causing frequent urination.

The average cup of coffee contains between 100 and 150 milligrams of caffeine per cup, instant coffee somewhat less, tea between 60 and 75 milligrams, cola drinks between 50 and 60 milligrams. This means that if you are drinking four or five cups of coffee each day you are getting a dose of 700 to 750 milligrams of caffeine. To any pharmacologist a dose over 250 milligrams is considered large, although about a third of people in the West get twice as much each day and one person in ten actually imbibes more than 1,000 milligrams of the drug caffeine every twenty- four hours. The full long-term implications of drinking coffee (and, to a lesser degree, tea and cola drinks) are still not clear. However, enough is known already to inspire any woman concerned about the preservation of her health and beauty to give them up completely. For caffeine is a stimulus you do not need on a healthful low protein, low-fat diet high in unrefined carbohydrates.

The link between caffeine intake and anxiety symptoms has been well established. Dr. John Greded, associate professor of psychiatry at theUniversity of Michigan, and his colleagues and others have reported that high caffeine consumers have statistically significant elevations in anxiety scores. The risk of developing peptic ulcers is also 1.4 times greater among coffee drinkers than among non-coffee drinkers. There is now evidence that coffee consumption by pregnant women can be dangerous to the unborn child Caffeine has been shown to cross the placental barrier where its mutagenic and perhaps even teratogenic potential may cause genetic changes and, therefore, birth defects.

Finally, a daily intake of caffeine from coffee drinking is the same as continuing to supply your system with any other drug to which it has to adjust and which ultimately it has to detoxify and eliminate. One of the main principles of any long-term diet for health and beauty is, never add to the body anything which is not necessary and with which it has to deal. The fewer toxic substances there are, the less contribution they will make to tissue sludge, premature aging of skin, and the subclinical vitamin and mineral deficiencies which result in falling hair, breaking fingernails, chronic fatigue, and mental disorders. In the Lifestyle Diet, coffee, tea, cola drinks (even those without sugar), and cocoa are out. Instead, you can drink mineral waters, herb teas (but always in moderation since some of them in excess may not be good for you either), fresh fruit and vegetable juices, and coffee substitutes made from roots and grains.
