- Food insecurity means that individuals or households do not have consistent access to enough food for an active, healthy life. This leads to insufficient calorie and nutrient intake. - Poor dietary habits involve consuming diets that are deficient in essential nutrients (vitamins, minerals, protein) or are unbalanced, even if calorie intake is sometimes sufficient. This is often linked to lack of awareness, affordability, and availability of nutritious foods. - Malnutrition in India includes undernutrition (stunting, wasting, underweight), micronutrient deficiencies ("hidden hunger"), and increasingly, overweight/obesity, often co-existing within populations or even individuals. Poor diet and lack of consistent access to varied, nutritious food underlies all these forms.
