Zhrnutie	The HFSM is the official U.S. government measure of household food security, used in the Current Population Survey and National Health and Nutrition Examination Survey since 1995. The 18-item full form and 6-item short form assess the frequency and severity of food insecurity within a household based on direct reports of food access constraints, dietary adjustments, and hunger. The HFSM is the standard for U.S. food security surveillance and policy evaluation.	The NLAI is a 26-item validated instrument measuring nutrition literacy—the ability to understand nutrition information and use it to make healthy food choices. Developed by Diamond and refined through validation studies by Rothman and colleagues, the NLAI evaluates comprehension of nutrition labels, understanding of portion sizes, knowledge of daily values, and ability to interpret nutrient claims. Nutrition literacy is a critical determinant of dietary quality and health outcomes, particularly in populations with low general literacy or limited numeracy.
