MCQ-> Throughout human history the leading causes of death have been infection and trauma, Modem medicine has scored significant victories against both, and the major causes of ill health and death are now the chronic degenerative diseases, such as coronary artery disease, arthritis, osteoporosis, Alzheimer’s, macular degeneration, cataract and cancer. These have a long latency period before symptoms appear and a diagnosis is made. It follows that the majority of apparently healthy people are pre-ill.But are these conditions inevitably degenerative? A truly preventive medicine that focused on the pre-ill, analyzing the metabolic errors which lead to clinical illness, might be able to correct them before the first symptom. Genetic risk factors are known for all the chronic degenerative diseases, and are important to the individuals who possess them. At the population level, however, migration studies confirm that these illnesses are linked for the most part to lifestyle factors — exercise, smoking and nutrition. Nutrition is the easiest of these to change, and the most versatile tool for affecting the metabolic changes needed to tilt the balance away from disease.Many national surveys reveal that malnutrition is common in developed countries. This is not the calorie and/or micronutrient deficiency associated with developing nations (type A malnutrition); but multiple micronutrient depletion, usually combined with calorific balance or excess (Type B malnutrition). The incidence and severity of Type B malnutrition will be shown to be worse if newer micronutrient groups such as the essential fatty acids, xanthophylls and falconoid are included in the surveys. Commonly ingested levels of these micronutrients seem to be far too low in many developed countries.There is now considerable evidence that Type B malnutrition is a major cause of chronic degenerative diseases. If this is the case, then t is logical to treat such diseases not with drugs but with multiple micronutrient repletion, or pharmaco-nutrition’. This can take the form of pills and capsules — ‘nutraceuticals’, or food formats known as ‘functional foods’, This approach has been neglected hitherto because it is relatively unprofitable for drug companies — the products are hard to patent — and it is a strategy which does not sit easily with modem medical interventionism. Over the last 100 years, the drug industry has invested huge sums in developing a range of subtle and powerful drugs to treat the many diseases we are subject to. Medical training is couched in pharmaceutical terms and this approach has provided us with an exceptional range of therapeutic tools in the treatment of disease and in acute medical emergencies. However, the pharmaceutical model has also created an unhealthy dependency culture, in which relatively few of us accept responsibility for maintaining our own health. Instead, we have handed over this responsibility to health professionals who know very little about health maintenance, or disease prevention.One problem for supporters of this argument is lack of the right kind of hard evidence. We have a wealth of epidemiological data linking dietary factors to health profiles/ disease risks, and a great deal of information on mechanism: how food factors interact with our biochemistry. But almost all intervention studies with micronutrients, with the notable exception of the omega 3 fatty acids, have so far produced conflicting or negative results. In other words, our science appears to have no predictive value. Does this invalidate the science? Or are we simply asking the wrong questions?Based on pharmaceutical thinking, most intervention studies have attempted to measure the impact of a single micronutrient on the incidence of disease. The classical approach says that if you give a compound formula to test subjects and obtain positive results, you cannot know which ingredient is exerting the benefit, so you must test each ingredient individually. But in the field of nutrition, this does not work. Each intervention on its own will hardly make enough difference to be measured. The best therapeutic response must therefore combine micronutrients to normalise our internal physiology. So do we need to analyse each individual’s nutritional status and then tailor a formula specifically for him or her? While we do not have the resources to analyze millions of individual cases, there is no need to do so. The vast majority of people are consuming suboptimal amounts of most micronutrients, and most of the micronutrients concerned are very safe. Accordingly, a comprehensive and universal program of micronutrient support is probably the most cost-effective and safest way of improving the general health of the nation.The author recommends micronutrient-repletion for large-scale treatment of chronic degenerative diseases because

MCQ-> Read the following passage and answer the questions. Passage:Where is this going?' That is the question at the heart of River of Life, River of Death, as author Victor Mallet travels the length of the Ganges. Beginning at its ice cave source in the Himalayan foothills. he follows the water through the holy confluence at Allahabad. the spindly banks of Varanasi city and onwards to the delta in Bangladesh. where 'in its parting gift to the land. the river spews millions of tons of fertile silt on to the rice fields of Bengal and the mangroves of the Sundarbans.' It is the same question he asks about the treatment of the Ganges. both good and bad. The river leads a double life. being the most worshipped waterway in the world and also one of the most polluted. The Ganges and its tributaries are now subject to sewage pollution that is 'half a million times over the Indian recommended limit for bathing' in places. not to mention the unchecked runoff from heavy metals, fertilizers. carcinogens and the occasional corpse. As Mallet observes. the danger of contamination does not put off the millions of revellers at Kuinbh Mela. It is a Hindu pilgrimage 'thought to be the largest gathering of people anywhere'. described to him as 'a spiritual expo... where you will be talking one moment to a visiting Mumbai businessman and the next to a marijuana-stoned yogi. He suggests the pollution might never deter them. He is told by one bather: 'we do believe that anyone who takes in this water. he becomes pure also. because it is always pure.' There is a collective sense that the spirit of the Ganges is so sacred that she can never be spoiled. He informs the reader in the preface — 'almost everyone knows the problems are real'. His journey down the Ganges is one of investigation rather than discovery. Mallet investigates the potential of the river to become a cradle for antibiotic-resistant infections — or superbugs' — that could be exported to other regions by global travel. He points out that some 450 million people depend on the Ganges water basin for survival, and many more for its religious and cultural importance. The Ganges is a goddess and a mother to everyone from the politician in the north, to the humblest Hindu living in the far south or running a motel in the United States. There is hope. Mallet draws some parallels to clean-ups of the Rhine and the Thames. He points to the design feat of Ktunbh Mela, which as 'a pop-up megacity' for two million pilgrims has better infrastructure and waste treatment than many Indian cities. 'In the minds of both Indians and foreigners. this raises important questions... if the authorities can build infrastructure so efficiently for this short but very large festival why can they not do the same for permanent villages and towns?'Which ONE of the options fills in the blank and completes the statement below correctly? The average believer is of the faith-driven conviction that the river Ganges....

MCQ->Dr. Puneet worried about the test results of his patient, Ms. Benita. Ms. Benita was an old rich widow with no dependents. The results indicate that Ms. Benita has the potentially fatal Lymphanigioleiomyomatosis (LAM) disease. LAM is rare and difficult to diagnose. People with LAM often need oxygen and lung transplants as the disease continues its course. According to the test results, Ms. Benita might have got it. Dr. Puneet explained the situation to Ms. Benita carefully. Without naming the disease, he explained that the disease was progressive and would need treatment using drugs which were still at the experimental stage. Even then, the chance of success was not too bright. If the treatment was unsuccessful, then they would have to get ready for a lung transplant. The lung transplant itself was a risky course of treatment. Even if successful, she would require constant medical support and treatment. Ms. Benita looked blank. She asks Dr. Puneet for his advice about the course of action. He nods gravely, ”I’m afraid, Ms. Benita, I think there is only one course we can take.” What should be Dr. Puneet’s advice?....
