The Global Health Crisis: Unhealthy Diets and Inactivity

The World Health Organization (WHO) highlights unhealthy diets and a lack of exercise as some of the biggest threats to global health today. But are their guidelines practical for everyone?

A Disconnect with Reality

Scott Lear, a health sciences professor at Simon Fraser University, argues that WHO's dietary recommendations are based on realities that do not apply to many parts of the world. In wealthier nations, spending on fruits and vegetables is manageable, and fitness activities like gym memberships are often within reach.

Diverse Physical Activity Patterns

"Physical activity patterns are clearly influenced by a country’s level of development and the income of individuals or households," Lear points out. He stresses that it isn't feasible to create guidelines for the 80% of the world based solely on the experiences of high-income countries.

Groundbreaking Research for Global Health

Lear was involved in the Prospective Urban Rural Epidemiology (PURE) study, which began in India in 2002 and expanded to 28 countries across five continents. This massive research project, involving 212,000 participants, delves into how societal factors influence chronic diseases globally.

The Unrealistic Expectation of Fruit and Veggie Consumption

According to WHO, individuals should consume at least five servings of fruits and vegetables daily (excluding starchy roots). However, Lear argues this is far from feasible for large segments of the population.

Farmers Caught in a Financial Bind

Interestingly, Lear found that many farmers in low-income countries struggle with this directive. He explains, "Field workers often say that if they consume what they grow, they will lose significant revenue from not selling it." For some farmers, meeting the five-serving recommendation could take up to 50% of their household income.

The Real Lives Behind the Numbers

Imagine asking someone who toils in the fields, mines, or construction sites all day to prioritize fruits and vegetables when their financial situation makes such choices nearly impossible. The gap between ideal guidelines and everyday reality remains vast and concerning.
