Signs of a nutrient imbalance in the diet may include fatigue, digestive issues, and changes in skin health or hair condition. For example, a deficiency in essential vitamins or minerals can lead to symptoms such as anemia from lack of iron, skin rashes from vitamin deficiencies, or brittle hair due to insufficient protein intake. Weight fluctuations, mood changes, and increased susceptibility to infections can also indicate nutrient imbalances. Regular monitoring of dietary intake and awareness of these signs can help individuals maintain overall health and prevent long-term complications associated with poor nutrition.
