Which of the following practices may lead to micronutrient deficiencies?

Unplanned restricted eating can lead to micronutrient deficiencies because this practice often involves cutting out entire food groups or limiting food intake without careful consideration of nutritional needs. When individuals limit their dietary intake without a structured plan or guidance, they may not consume enough variety of foods to meet their essential micronutrient requirements. This lack of planning can result in insufficient intake of vitamins and minerals, which are crucial for various bodily functions, including immune health, energy production, and cognitive functioning.

In contrast, regular exercise, planned weight management, and balanced diets are typically associated with promoting overall health and can help maintain or improve micronutrient status when appropriately managed. Regular exercise combined with a balanced diet supports nutrient absorption and utilization, while planned weight management can facilitate mindful eating habits that prioritize nutrient-dense foods. On the other hand, balanced diets are designed to include a wide range of nutrients, minimizing the risk of deficiencies by incorporating various food groups.
