Question

Scientists have found connection between diet and disease. For example in a clinical study of 20,000 men, consuming fish once a week was linked to a 52 per cent reduction in the risk of sudden death from heart attack. Fish is high in omega-3 fatty acids, which are essential components of cells and can protect the heart from abnormal heart rhythm. In another clinical study of more than 42,000 women, those who ate lots of fruits, vegetables, whole grains, low-fat dairy products, and only lean meats lived longer. High intake of fruits, vegetables, and legumes was associated with a lower risk of developing heart disease.

What can you conclude about

1. role of the diet in disease causation?
2. role of the diet in disease prevention?

Answer 1

1. Role of Diet in Disease Causation:
   • An unhealthy diet can increase the risk of developing diseases.
   • Lack of essential nutrients or excessive intake of unhealthy foods may lead to health problems like heart disease, obesity and other disorders.
   • Diets high in unhealthy fats and low in protective nutrients can negatively affect the body.
2. Role of Diet in Disease Prevention:
   • A balanced and nutritious diet helps prevent many diseases.
   • Foods such as fish, fruits, vegetables, whole grains, legumes and low-fat dairy products provide essential nutrients that protect health.
   • Omega-3 fatty acids in fish help protect the heart and reduce the risk of heart-related problems.
   • A healthy diet improves overall health and increases life expectancy.
