Acid Reflux Disease: The Truth On Why You Have Heartburn

Heartburn, or GERD - gastro-esophageal reflux disease as it is known, is caused by the coincidence of two medical conditions. The first condition contributing to acid reflux disease is the backward flow of food and acid from the stomach to the esophagus. Nonetheless, the reflux does not always result in symptoms of acid reflux disease or changes in the organic tissues, and can happen in healthy individuals as well, when it is referred to as "physiologic gastroesophageal reflux".

The second factor encouraging acid reflux is a malfunction of the LES, the lower esophageal sphincter. The LES is a circle of muscle acting as a valve between the esophagus and the stomach, measuring 3-4 cm, some two to three times thicker than the proximal esophagus. In cases of acid reflux disease, the stomach contents is pushed back into the esophagus because the LES does not shut properly. This is then called acid reflux disease, when symptoms of the disease then follow.

The typical sensation of acid reflux disease is persistent (twice weekly or more) heartburn. Heartburn is the burning feeling in the chest or the throat, when the stomach contents is pushed back to the lining of the esophagus. As people in good health may also have light reflux, occasional heartburn is common as well and does not immediately mean acid reflux disease.

Other sufferers of acid reflux disease may also feel chest-pains or suffer from coughs, hoarseness in the morning, vocal changes, problems in swallowing (notably lumpy foods), lasting earache, burning pains in the chest, nausea or sinusitis. Some sufferers describe sensations of food being stuck, choking or tightness in the throat. This is caused by the continual flow back of stomach contents in contact with the esophagus, resulting in swelling of the esophagus due scars from histological damage.

Acid reflux disease left untreated can have serious health consequences. These include constriction, bleeding, ulcers and spasms of the esophagus. When the acid from the stomach gets to the trachea as well as the upper esophagus, several severe conditions such as asthma, sinusitis and pneumonia can occur. Some patients can develop a condition known as Barrett's esophagus, where abnormal shapes and colors of cells occur in the esophageal lining. This is an initial stage before esophageal cancer, notably in adults over 60 years old.

There are three options for treating acid reflux disease: surgery, medical therapy and holistic therapy that includes changes in diet and lifestyle and taking specific herbal supplements. Using surgery merits very careful consideration, given that certain underlying conditions can be complicated, such as constriction and muscular contraction disorders. PPIs and H2 blockers are among the options for medical intervention in cases of acid reflux disease. While it is possible to apply prescribed medications or acid blockers like these, remember that the results are sometimes only temporary and that conventional medicine can lead to serious side effects.

GERD, seen from a holistic viewpoint, is a warning signal for an internal imbalance of consequence that must be correctly treated. For this reason, alternative medicine such as herbal medicine, changes in lifestyle, homeopathic remedies as components of a complete holistic schedule are the clear recommendation for heartburn sufferers.

Stomach Cancer, Symptoms, Causes, Diagnosis, Treatment, Prognosis

Stomach cancer is common throughout the world and affects all races, it is more common in men than women, and has its peak age range between 40 and 60 years old. Stomach cancer mortality is higher in Japan and Chile, presumably because of the different diets in those countries where they are less dependent on red meat.


Over the last 25 years the incidence of stomach cancer in the western world has decreased by 50% and the resulting death rate is less than a third of what it used to be but in less developed countries it is still a major cause of death, probably because in these countries by the time the disease is diagnosed (usually by means of a Barium meal) the stomach cancer is at a very advanced stage.

TYPES OF STOMACH CANCER
There are several different types of stomach cancer, some of which are very rare. The most common types of stomach cancer start in the glandular cells of the stomach lining (adenocarcinomas), this is where stomach acid and digestive enzymes are made, and where most stomach cancers start. When the stomach cancer becomes more advanced, it can travel through the bloodstream and spread to organs such as the liver, lungs, and bones. Stomach cancers that start in the lymphatic tissue (lymphoma), in the stomach muscular tissue (sarcoma) or in the tissues that support the organs of the digestive system (gastrointestinal stromal tumors) are less common and are treated in different ways.

SIGNS AND SYMPTOMS
Early clues to stomach cancer are chronic dyspepsia and epigastric discomfort, followed in later stages by weight loss, anorexia, a feeling of fullness after eating, anemia and fatigue. Blood in the stools may also be present and if the Cancer is in the Cardia (top) vomiting may occur.

CAUSATION
The exact cause of stomach cancer is unknown although the presence of the Helicopter pylori bacterium seems to be a major factor. Predisposing factors include environmental influences such as smoking and high alcohol intake. Because stomach cancer is more common amongst those with a family history and with people with type A blood, genetic factors are also implicated. Dietary factors, particularly methods of food preservation such as pickling, smoking or salting also have an influence on the prevalence of stomach cancer.

DIAGNOSIS
Stomach cancer is diagnosed through an examination that may include an upper gastrointestinal (GI) series; endoscopy or gastroscopy where a thin flexible tube is passed down the throat so the doctor can see into the stomach, esophagus and upper part of the bowel Barium meals and Barium swallows. Because stomach cancer can spread to the liver, the pancreas, and other organs near the stomach as well as to the lungs, the doctor may order a CT scan, a PET scan, an endoscopic ultrasound exam, or other tests to check these areas.

Stomach cancer can spread (metastasize) to the esophagus or the small intestine, and can extend through the stomach wall to nearby lymph nodes and organs. Metastasis occurs in 80-90% of individuals with stomach cancer, with a five year survival rate of 75% in those diagnosed in early stages and less than 30% of those diagnosed in late stages.

TREATMENT
Although stomach cancer may be treated with surgery, radiation therapy, or chemotherapy, in many cases surgery is the treatment of choice. Even in patients whose disease is not considered surgically curable, resection offers a palliative effect and improves potential benefits from chemotherapy.

The nature and extent of the cancer determines what kind of surgery is most appropriate. Common surgical procedures include, partial and total removal of the stomach.
Antiemetics can control nausea, which increases as the cancer advances. In the more advanced stages, sedatives and tranquilizers may be necessary to control anxiety. Narcotics are commonly necessary to control sever and unremitting pain.
In some cases of advanced stomach cancer, a laser beam directed through an endoscope can vaporize most of the tumor and relieve obstruction without an operation.

PROGNOSIS
Stomach cancer is curable if detected early, but most people do not seek medical help until the disease is quite advanced, possibly because symptoms occur late and are often vague and non-specific. Eating fresh fruits and vegetables that contain antioxidant vitamins (such as A and C) appears to lower the risk of stomach cancer. The rate of stomach cancer is about doubled in smokers so the cessation of smoking is essential.

In the United States and most of the Western world, the 5-year survival rate ranges from 5% to 15%. In Japan, where stomach cancer often is diagnosed early, the 5 year survival rate is about 50%. Five year survival rates for more advanced stomach cancers range from, around 20% for those with regional disease to almost nil for those with distant metastases.

Treatment for metastatic stomach cancer can relieve symptoms and sometimes prolong survival, but long remissions are not common. The survival of inoperable stomach cancer is usually only a few months if untreated. With chemotherapy the average survival is about 12 months. If cancer is found before it has spread, the five-year relative survival rate is about 61%.

Vegetarian Diets for Preventing Bowel and Stomach Diseases

A vegetarian diet is known to provide a wide range of health benefits. Research has shown vegetarians to suffer less heart disease, diabetes, hypertension, obesity, various cancers, diverticular disease, gall stones, kidney stones, osteoporosis and bowel disorders.

Vegetarian diets have also been used in the treatment of various illnesses.Many of the health benefits derived from a vegetarian diet have to do with creating a healthy environment in the bowels and stomach. Our digestive systems, from prehistory on, were designed to metabolize vegetable matter, more than animal products. Fruits, vegetables, legumes and nuts provide the kind of dietary fiber our digestive systems need to function properly. The Western diet that's high in processed and refined flour and sugar, and in animal products that are laden with hormones and antibiotics, are actually anathema to our insides.

When the digestive system doesn't function and work as it's intended to, that leads to opportunistic diseases or changes in the DNA of cells in the stomach and colon. And there are more practical considerations as well. When we don't get enough of the fiber we need, we incur a host of digestion and elimination problems, such as constipation and hemorrhoids that are a result of straining. These diseases and syndromes are much less evident in a vegetarian population than in a meat-eating population.

Diverticular disease affects the colon and symptoms include lower abdominal pain and disturbed bowel habit. It occurs frequently in western countries where intake of dietary fibre is low. Diverticular disease is found to be less frequent in vegetarians, 12% of vegetarians studied having diverticular disease compared with 33% of non-vegetarians. This is thought to be due to the increased fibre of vegetarian diets.

Other diseases of the bowel that occur less frequently in a vegetarian population include irritable bowel syndrome, and chronic ulcerative colitis, mostly likely due to the increased fiber content in a vegetarian diet. And of course a diet that's higher in dietary fiber that comes from a vegetarian diet will decrease the likelihood or risk of colon cancer.

When you consider the risks that come with a diet that includes meat and animal products, and the benefits that come from a vegetarian diet, does the prospect of a steak or burger or bacon really sound that good to you? Doesn't it at least make sense to reverse the portion sizes and proportions of meats to vegetables and side dishes? In other words, if you must continue to eat meat, then make meat your side dish, or just incidental to your meal, such as in a stir fry. Increasing the proportion of fruits and vegetables in your diet can only be good for you.

The Secret Power of Vegetarians

Most people who don't know anything about the vegetarian lifestyle think that is must be pure drudgery being a vegetarian and giving up meat. That is a misconception because even though meat is not a part of a vegetarian diet, it isn't about what you are going without, it is what is in your diet and in your life that makes a vegetarian lifestyle work so well. If you actually interviewed a vegetarian, the last thing they would say is that they are all about not eating meat. Instead they are about living in healthy way in a way that is at peace with the environment and with their own bodies.

The body of knowledge about vegetarians that most people don't know is pretty astounding. Most people do understand the basic three reasons someone becomes a vegetarian which are health, animal rights and spiritual or moral reasons. But there are a number of side benefits and little secrets only vegetarians know that if they became popularized, the flood of converts to vegetarianism would be overwhelming. Some of those little secrets includes :

1.Vegetarians are not depressed as much as others because they know some secrets to overcoming depression naturally.
2.Vegetarians do not struggle with weight issues as much as others.
3.Vegetarians are better informed about nutrition and know how to make the most of what they eat.
4.Vegetarians sleep better, are more energetic and need less sleep than meat eaters.
5.Vegetarians have a much reduced incidence of cancer, heart disease and digestive disorders.
6.Vegetarians live longer than meat eaters.

One secret vegetarians know that gets almost no press is the power of walnuts. There is a little known chemical in walnuts called serotonin that is a powerful antidepressant. Now you can get your doctor to prescribe an artificial anti depressant which can cost you a lot of money and put you at risk for chemical dependency. Or you can make a nice hot cup of tea with walnut as part of the mix. About half a walnut shell mixed in with your regular tea brew fills the drink with serotonin. Taken regularly, you will feel the effects of a chemical pick me up that can combat depression very effectively.

Another little secret of vegetarians runs against the normal rules of dieting to get the full value of nutrients you might expect from eating a salad. Diet theory would have you use no salad dressing or at very least a zero fat or low fat salad dressing. Vegetarians who are more in touch with the effects of foods in their bodies know that the real value of eating salad are the natural nutrients in leafy vegetables called carotenoids. But science has shown us that the best way to pull cerotenoids from green vegetables is to use a higher fat salad dressing. So enjoy that fatty dressing because your vegetarian lifestyle will deliver plenty of weight loss value to you even with this small indulgence that can do you so much good.

Speaking of tea, green tea is often a staple of a vegetarians diet because of the little health secrets buried in this amazing drink. Green tea has powers to help your digestive system, help combat depression and to accelerate weight loss that ancient cultures like the Chinese and India have known for centuries. Vegetarians have caught up on this secret of health knowledge ahead of us so its time well learned from their wisdom.

These are just a few of the wisdom of the ancients that have been rediscovered by the modern vegetarian "craze". But it really isn't a craze because once you start living a healthy life cashing in on these many benefits a vegetarian lifestyle will give you, you will never want to go back.

The Truth About Easy Vegetarian Recipes

There has been much talk about new vegetarians and critics about finding an easy vegetarian recipe. In some cases, the need to find an easy vegetarian recipe is motivated not just by the need to really find one but to satisfy curiosity as well. Is there really such a thing as an easy vegetarian recipe?

The Value of Cooking at Home

Some new vegetarians may be tempted to easily buy take outs at vegetarian restaurants. Most of us know however that there are great advantages to cooking meals at home. Home cooked meals are almost always cheaper to prepare and have the additional benefit of binding members of a family in a comfortable atmosphere. One other major plus factor for you as a vegetarian is that you are 100% sure of the cleanliness of your vegetables and what exactly goes into a dish.

Knowing What Type You Belong To

The first step to finding the right easy vegetarian recipe to cook and serve is to find out what type of vegetarian you are and the people you are going to cook for. The most common type of vegetarian is the lacto-ovo-vegetarians who eat vegetables, fruits, eggs and dairy products. A lacto vegetarian eats the same kinds of food except for the eggs.

If you are a vegan type of vegetarian, then you would probably want to do away with any animal meat and animal-based food in your easy vegetarian recipe. There are other kinds of vegetarians but these are the most common. Once you know where you, your family and your friends belong to, finding an easy vegetarian recipe will be easier.

The Recipe Myth

A common misconception with vegetarian recipes is that they are complicated to prepare. Since most vegetarians also lead busy lives, this may seem discouraging. There is however no truth to this common belief. In fact, some vegetarian recipes are the easiest to prepare.

Some vegans for example simply puree or blend fruits and vegetables for truly fresh and satisfying fibrous meals. Less strict vegetarians however also have a variety of choices. For lacto-ovo-vegetarians for example the only thing that needs to be omitted are meat products and meat based products. This means that you can basically sauté or steam anything you like as long as there isn't any meat in it. For a truly substantial, tasty and healthy easy vegetarian recipe, you can substitute meat with tofu, beans, legumes and nuts.

Stocking


It is advisable for vegetarians to stock variety of fruits, vegetables, grains and dairy products at home. Aside from the usual fruits and vegetables, you can also stock up on spices, seeds, olive oil, pasta, rice, cereal and noodles. Just imagine what you can cook up even with just these basic ingredients. An easy vegetarian recipe can be as convenient as sautéing some vegetables, spices, beans, tomato sauce and topping it on rice.

Washing

One thing you have to remember about any easy vegetarian recipe is that you have to properly wash and clean all of your fruits and vegetables even those with inedible peelings. Most of these food items have changed hands so often before reaching you that they're bound to carry some dirt or bacteria. Wash your food with running water and use a brush for fruits and vegetables with dimpled, corrugated or hard skins.

Are Vegan Supplements Good for Strict Vegetarians?

The question as to whether or not vegan supplements are good for strict vegetarians cannot be answered or understood without a complete understanding of the meaning of the terms 'vegan' and 'vegetarian'.

Where eating meat is concerned, there are several different types of diet, one extreme being the Atkins Diet where devouring animal flesh and fats is positively encouraged. However, it is not that extreme we are concerned with here, but the opposite, where no meat is eaten. Is there anything in a vegan diet that there is not in a vegetarian diet, or are vegan supplements harmful to strict vegetarians? These are questions that we shall now look at from a scientific viewpoint, since emotions are not involved in the answer to the question.

It is certainly true that for many people, emotions are very much involved in the distinction between an omnivore and vegetarian, and also between a vegetarian and a vegan. Some of these have to do with the concept of eating 'friendly furry animals' and others to do with the ethics of breeding animal life for the sole purpose of eating it. While these concepts have nothing whatsoever to do with the scientific arguments, they have a lot to do with the various types of eating habit used throughout the world.

Some reasons for a vegetarian diet are imposed by local agricultural and husbandry conditions, where meat is simply not available to most people, others due to religious beliefs and yet others to personal feelings of disgust at the moral arguments involved in eating animals that have been bred specifically for that reason. If we take carnivores and omnivores out of the equation, including those that do not eat red meats, but eat chicken and fish, what do we have?

Vegetarians that eat dairy products and eggs are referred to officially as lacto-ovo-vegetarians. The reasons for the name are obvious. They eat eggs, cheese and yoghurt and also drink milk. The strict vegetarians, on the other hand, who are part of the subject of this article, eat vegetables and dairy products such as yoghurt and cheese, but omit eggs. Then, finally, we have the vegans that eat only vegetable matter and no dairy products or animal based food at all. Each of these, you would think, would have a decreasing intake of nutrients essential for healthy and healthy growth.

A vegetarian diet, as opposed to that of a vegan, contains many nutritious foods that omnivores also eat, such as pulses (lentils, peas, beans), grains (wheat, oats), nuts, seeds and vegetable and fruits of any form. It can also include protein in the form of soy protein and tofu that can be formed into sausages, burgers and other meat-like products. Why vegetarians should want to make their foods look like meat is unknown, but that seems to what they prefer. The likely reason is that the majority of vegetarians and vegans became so after eating meat, and it helps them to stick to their diet by eating food in familiar forms.

Many have started their diets with what they know, and have substituted soy for minced beef in their spaghetti sauce, for example, and quorn for beef in their burgers. Together with a good piquant tomato sauce it is hard to tell the difference. Other than truly meaty dishes such as steaks, then, most meat dishes can be substituted for vegetarian alternatives or substitutes.

However, what does this do to the vegetarian's nutrition? How does the vegetarian maintain a sufficient intake of minerals, vitamins and other nutrients by eliminating meat from their diet? Let's have a look at some of the nutritional content of fish and meat that vegetarians are apparently not getting.

The first is protein, the main source for most people being from the flesh of meat and fish. Protein is essential for the maintenance of healthy muscles, vital organs, skin, and believe it or not, bones. A vegetarian eating eggs has no problems with protein, since eggs and cheese are full of it. There is also the protein in soy based foods and in quorn, a mycoprotein derivative of fungi. Nuts, peas, beans, cereal grains and seeds are all rich in proteins and the vegetarian does not have a problem in consuming an adequate supply of protein.

If we come to minerals, the most important for the health of your blood is iron. Green vegetables and whole grains are good sources of iron, as are pulses and some fruits. However, it is animal sources of iron that the body most easily absorbs, and in order for it to make use of vegetable sources, you should consume a good intake of vitamin C by eating plenty of fruits and green vegetables. You must take these at the same time as the vegetables that contain iron, or the iron will not be absorbed into the body. Otherwise, the vegetarian has a sufficient iron intake to maintain the health of their red blood cells.

The other critical mineral is calcium, essential for healthy bones and teeth. Many dark green vegetables are good sources of calcium, as are turnips, swedes and fortified soy milk. Zinc, too, is essential and without it many enzymes could not be synthesized by your biochemistry, and it is also necessary in the male reproductive system. Zinc, too, has many vegetarian sources, such as nuts, wheat germ and whole grains, and is also contained in soy.

So far in this evaluation neither vegetarians nor vegans have been seriously compromised by their diet, although there are arguments that a vegetarian diet can harm young children since there is insufficient protein available to allow normal growth and development. This is currently under debate, and it is a matter for parents to consider whether or not their children should be raised on a purely vegetarian diet.

However, when it comes to a vital vitamin that is necessary for the production of red blood cells and the prevention of anemia, vegans become unstuck. Vitamin B-12 is found predominantly in dairy products and other animal products. It is claimed that cereals enriched with B-12 and fortified soy products provide this vitamin to vegans, but what are the sources of the vitamin that is used as a supplement?

It is generally accepted that vegans require vitamin B-12 supplements, and also others such as calcium that they might be deficient in due to their diet. It is possible that the only real supplement needed is vitamin B-12, although many nutritionists claim that both vegetarians and vegans should take supplements to boost intake of those nutrients of which the normal route to the body is through eating foods of animal origin.

There are many nutrients obtainable from animal sources that are classed as neither vitamins nor minerals, and for which there are adequate supplements to suit the needs of vegans and vegetarians alike. Further evidence is needed, however, that vegans are deficient in these since many of them have alternatives of vegetable origin that might annul their necessity.

One thing, however, is absolutely certain, and that is the answer to the original question. It is absolutely true that vegan supplements are good for strict vegetarians. The reason for this is that vegan supplements are designed to replace not only nutrients that the body might be deficient in due to a strict vegetarian diet, but also those missing by the absence of dairy products such as milk, cheese and yoghurt.

Vegetarians will also benefit from such supplements, and it could be important to their health that both vegetarians and vegans take them.
