Nutritional disorders are health issues that arise from an imbalance in nutrient intake, either from deficiencies or excesses. Common examples include malnutrition, which can result from inadequate consumption of essential vitamins and minerals, and obesity, caused by excessive calorie intake. These disorders can lead to serious health problems, including weakened immune function and chronic diseases. Prevention and management of nutritional disorders often involve dietary changes and education about healthy eating habits. Consulting with healthcare professionals, such as dietitians, can help individuals create balanced meal plans that meet their nutritional needs and promote overall well-being.
