Food insecurity refers to the lack of reliable access to sufficient, affordable, and nutritious food. It can affect individuals and families, leading to hunger and malnutrition. Factors contributing to food insecurity include poverty, unemployment, and high living costs, which make it difficult for people to purchase the food they need. In many regions, food insecurity can also be linked to systemic issues such as economic inequality and limited access to education. Organizations like food banks and community programs work to alleviate food insecurity by providing resources and support to those in need, helping to ensure that everyone has enough to eat.
