Limited access to food is a significant cause of malnutrition because it directly affects a person's ability to obtain sufficient nutrients necessary for maintaining health. When individuals or communities do not have reliable access to a variety of foods, they may experience deficiencies in essential vitamins, minerals, and macronutrients. This can lead to various health issues, including stunted growth in children, weakened immune systems, and chronic diseases in adults. Social, economic, and environmental factors often contribute to this lack of access, highlighting the complex nature of food security and its impact on nutrition.

In contrast, lack of exercise, excessive vitamin intake, and high caloric intake can contribute to health issues but are not primary causes of malnutrition in the same way that limited access to food can lead to significant nutrient deficiencies.
