How nutrition needs change across life
Direct answer: ICMR-NIN says nutrient requirements vary with age, gender, physiological status and physical activity. The foundation stays the same at every stage: a varied diet from several food groups. What changes is the emphasis, such as extra food in pregnancy, calcium in the teen years, and nutrient-rich foods in later life.
What stays the same at every age?
A varied diet from at least 5–7 food groups a day, safe water, and regular physical activity.
What changes?
ICMR-NIN highlights foods of animal origin such as milk, eggs and meat particularly for pregnant and lactating women, children and adolescents, and nutrient-rich foods such as pulses, lean meat, fish and eggs for older adults.
Where can I get personal advice?
From a doctor or dietitian, who can look at your age, health and activity.
