Food deficiency occurs when individuals do not consume enough essential nutrients, such as vitamins, minerals, proteins, and carbohydrates, needed for proper health and development. This lack of nutrients can lead to various health issues, including weakened immune systems, stunted growth in children, and increased susceptibility to diseases. Common causes of food deficiency include poverty, lack of access to diverse foods, and poor dietary choices. Certain populations, such as those living in food deserts or experiencing malnutrition, are particularly vulnerable. Addressing food deficiency requires improving access to nutritious foods and promoting healthy eating habits.
