Food Fortification

Food fortification means adding essential vitamins and minerals to commonly eaten foods to improve their nutritional quality. Staple-food fortification uses foods consumed regularly by large sections of the population to increase micronutrient intake, helping prevent deficiencies without requiring major changes in eating habits.

How regular consumption prevents deficiency

A fortified staple supplies a small additional quantity of selected nutrients each time it is eaten. Sustained consumption can help close the gap between usual dietary intake and nutritional requirements.

• The nutrient must remain sufficiently stable during storage and cooking and have adequate bioavailability, meaning that the body can absorb and use it.
• Iron supports haemoglobin formation, while folate and vitamin B12 support normal red blood cell production.
• Iodine is needed for thyroid hormone production, while vitamin A supports normal vision.

Why staples provide population-wide reach

Using a widely consumed food vehicle allows fortification to reach people repeatedly through their ordinary meals, rather than relying solely on individuals to seek supplements.

• The choice of staple must reflect local consumption patterns, because people benefit only if they regularly eat the fortified product.
• Public food programmes can distribute fortified staples to vulnerable groups, including low-income households and children.
• Benefits depend on reliable supply and coverage; households consuming mainly home-produced or locally milled foods may be missed by centrally processed fortified products.

Staple-food fortification in India

The Food Safety and Standards Authority of India specifies standards under the Food Safety and Standards (Fortification of Foods) Regulations, 2018.

• Fortified rice and wheat flour contain iron, folic acid and vitamin B12.
• Fortified milk and edible oil contain vitamins A and D.
• Double-fortified salt contains both iodine and iron.

Conditions for effectiveness and limits

Fortification is a complementary public-health measure, not a replacement for a diverse diet, sanitation or healthcare.

• Nutrient levels must account for usual food consumption and safety, since both inadequate addition and excessive intake can undermine the intervention.
• Quality assurance and monitoring must check nutrient content, population coverage and changes in deficiency levels.
• Anaemia has several causes, including nutritional deficiencies, infections and inherited blood disorders; iron fortification cannot prevent or treat every case.
• Fortification does not correct inadequate energy or protein intake, and severe deficiency requires clinical assessment and appropriate treatment.
