Nutrient deprivation occurs when the body does not receive enough essential nutrients, such as vitamins, minerals, proteins, fats, and carbohydrates. This lack can result from inadequate dietary intake, poor absorption, or increased nutrient needs due to factors like illness or stress. Over time, nutrient deprivation can lead to various health issues, including weakened immunity, fatigue, and impaired growth. Common causes of nutrient deprivation include restrictive diets, food scarcity, and certain medical conditions. For example, individuals with celiac disease may struggle to absorb nutrients properly, while those on a vegan diet might need to ensure they get enough vitamin B12 and iron. Addressing nutrient deprivation often requires dietary adjustments or supplementation.
