How does food insecurity primarily affect the health of vulnerable populations?

Food insecurity primarily affects the health of vulnerable populations by leading to malnutrition and chronic diseases. Individuals experiencing food insecurity often lack access to sufficient, safe, and nutritious food, which can result in inadequate calorie and nutrient intake. This inadequacy may manifest as malnutrition, characterized by both undernutrition, where individuals do not get enough nutrients, and overnutrition, where poor dietary choices lead to obesity and associated chronic diseases like diabetes, heart disease, and hypertension.

Moreover, food insecurity can exacerbate existing health issues and create barriers to managing health conditions due to inconsistent access to healthy food options. Vulnerable populations, including low-income families and individuals, often face these challenges, which can severely limit their overall health outcomes and quality of life. Addressing food insecurity is therefore crucial for improving the health status of these groups and reducing health disparities.
