User: Write a short paragraph on the impact of nutrition on human health.
Assistant: While it is obvious that nutrition should impact health, the modern medical paradigm has refused to account for, or at least minimised, its role in human health. Food is critical to human survival, and nutritious food is a prerequisite for creating and maintaining a healthy human body and mind. Consuming the wrong kinds of foods can wreak havoc on human metabolism, and over time, lead to hormonal disorders, obesity, diabetes and heart disease. The world is witness to increased cases of such disorders since the time of the industrialisation of the food and pharmaceutical industries. After World War 2, since the 1970s, the rates of incidence of the aforementioned diseases have increased manifold, correlated strongly with the increased consumption of processed foods, seed oils, sugar and carbohydrates while being negatively correlated with the consumption of saturated fats and red meat. Thus, while the average life expectancy of human beings has increased, albeit differently for different regions of the world, with the increasing contribution of modern medical practice, the quality of life for most people has decreased. The case can be made that we, as a society, are becoming calorie-rich but nutrient-poor, with negative outcomes for public health.
