In a recent Instagram post, Delhi-based nutritionist Lovneet Batra emphasized the importance of recognizing subtle signs of nutritional deficiencies. Common symptoms like brain fog, which may indicate a lack of healthy fats, and brittle nails, often linked to low biotin or zinc, can reveal underlying health issues. Batra also pointed out that recurring night leg cramps could suggest deficiencies in magnesium or potassium, while bleeding gums might signal declining Vitamin C levels. Additionally, unexpected mood swings may stem from unstable blood sugar levels. By incorporating nutrient-rich foods such as walnuts, eggs, bananas, and amla into their diets, individuals can address these deficiencies and improve their overall health.
