Throughout human history the leading causes of death have been infection and trauma. Modern 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, analysing 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 flavonoids 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 it 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 modern 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 tiny single micronutrient in 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 this approach, this does not work. Each intervention on its own will hardly make enough difference to be measurable, especially when you are dealing with chronic diseases where the metabolic errors happen over long periods. 
The only explanation for this is anthropological. Once established in calcified organizations, humans do two things: sabotage changes that might render people dispensable, and ensure industry-wide emulation.
In the 1960s, German auto companies developed plans to scrap the entire combustion engine for an electrical design. (The same existed in the 1970s in Japan, and in the 1980s in France.) So for 40 years we might have been free of the wasteful and ludicrous dependence on fossil fuels. Why didn’t it go anywhere? Because auto executives understood pistons and carburettors, and would loath to cannibalize their expertise, along with most of their factories.

Question: 1

The author recommends micronutrient-repletion for large-scale treatment of chronic degenerative diseases because

Show Hint

Focus on the link between deficiency and disease causation when considering treatment options.
Updated On: Aug 1, 2025
  • it is relatively easy to manage.
  • micronutrient deficiency is the cause of these diseases.
  • it can overcome genetic risk factors.
  • it can compensate for other lifestyle factors.

The Correct Option is B

Solution and Explanation

The passage explains that Type B malnutrition, which is characterized by micronutrient depletion, is a major cause of chronic degenerative diseases. Therefore, repletion of micronutrients can help address the root cause of these diseases. Thus, the Correct Answer is: \[ \boxed{(2) \ \text{micronutrient deficiency is the cause of these diseases.}} \]

Question: 2

Tailoring micronutrient-based treatment plans to suit individual deficiency profiles is not necessary because

Show Hint

Consider the broader population-level solutions when individual tailoring is impractical or unnecessary.
Updated On: Aug 1, 2025
  • it is very likely to give inconsistent or negative results.
  • it is a classic pharmaceutical approach not suited to micronutrients.
  • most people are consuming suboptimal amounts of safe-to-consume micronutrients.
  • it is not cost effective to do so.

The Correct Option is C

Solution and Explanation

The passage mentions that most people are consuming insufficient micronutrients, so tailoring treatment plans for individuals may not be necessary at the population level, as the deficiency is widespread. Therefore, the Correct Answer is: \[ \boxed{(3) \ \text{most people are consuming suboptimal amounts of safe-to-consume micronutrients.}} \]

Question: 3

Type-B malnutrition is a serious concern in developed countries because

Show Hint

Focus on the link between malnutrition and chronic diseases when assessing the impact of poor diet.
Updated On: Aug 1, 2025
  • developing countries mainly suffer from Type-A malnutrition.
  • it is a major contributor to illness and death.
  • pharmaceutical companies are not producing drugs to treat this condition.
  • national surveys on malnutrition do not include newer micronutrient groups.

The Correct Option is B

Solution and Explanation

The passage states that Type-B malnutrition, caused by multiple micronutrient depletion, is a key factor in the rise of chronic degenerative diseases, leading to illness and death. Therefore, the Correct Answer is: \[ \boxed{(2) \ \text{it is a major contributor to illness and death.}} \]

Question: 4

Why are a large number of apparently healthy people deemed pre-ill?

Show Hint

Consider the role of latency in the development of diseases when determining pre-illness status.
Updated On: Aug 1, 2025
  • They may have chronic degenerative diseases.
  • They do not know their own genetic risk factors which predispose them to diseases.
  • They suffer from Type-B malnutrition.
  • There is a lengthy latency period associated with chronically degenerative diseases.

The Correct Option is D

Solution and Explanation

The passage explains that chronic degenerative diseases have a long latency period, meaning that individuals may appear healthy until symptoms eventually develop, making them pre-ill. Therefore, the Correct Answer is: \[ \boxed{(4) \ \text{There is a lengthy latency period associated with chronically degenerative diseases.}} \]
