Final answer:
Food and agriculture affect health through the nutrient and energy density of foods, the impact of undernutrition on global populations, and the prevention of foodborne diseases by ensuring food safety and proper hygiene practices.
Step-by-step explanation:
There are several ways that food and agricultural factors affect nutrition and health. Here are three significant ways:
- Nutrient and Energy Density: Understanding nutrient and energy density in foods can lead to healthier food choices. A diet rich in nutrients yet appropriate in energy content is crucial for maintaining health and preventing diseases such as obesity and malnutrition.
- Global Undernutrition: Undernutrition affects populations globally, even in wealthier nations, leading to health issues like stunted growth in children and weakened immune systems. Public health initiatives are essential in treating and preventing such conditions through education and resource distribution.
- Prevention of Foodborne Diseases: Food safety is crucial for preventing diseases. Causes of foodborne illnesses include microorganisms and toxins. Symptoms vary widely but prevention relies heavily on good hygiene and proper food handling, preparation, and storage.
