While protein is abundant in many foods, a concerning issue in Bangladesh is the widespread occurrence of protein deficiency. Protein malnutrition, often referred to as "protein-energy malnutrition" (PEM), is a growing challenge affecting both children and adults across the country. But why is this happening? Let's explore the reasons behind the prevalence of protein deficiency in Bangladesh. 1. Poverty and Limited Access to Nutritious Food One of the main drivers of protein deficiency in Bangladesh is poverty. A significant portion of the population, especially in rural areas, struggles with poverty, limiting their ability to purchase adequate amounts of protein-rich foods. Protein sources such as meat, fish, eggs, and dairy products are often expensive, making them inaccessible to man...
