Hidden hunger

Also called: Micronutrient deficiency · Topic: Agricultural Marketing, MSP, Buffer Stocks and PDS · NCERT: Beyond NCERT

Meaning

Hidden hunger is a lack of essential micronutrients (vitamins and minerals) such as iron, zinc, iodine or vitamin A, even when a person eats enough calories.

It is called "hidden" because the person does not feel hungry and may not look starved, yet the body is still short of what it needs. It matters because it weakens health, learning and work capacity quietly. In India it shows up on a very large scale as anaemia and stunting.

Explanation

Calories are not the same as nutrients

• Macronutrients: carbohydrates, proteins and fats. The body needs them in large amounts, mainly for energy (calories).
• Micronutrients: vitamins and minerals. The body needs them only in tiny amounts, but it cannot work properly without them.
• A person can fill their stomach with rice or wheat and get enough calories, but still lack iron, zinc, iodine or vitamin A.
• Hunger in the usual sense is a lack of calories. Hidden hunger is a lack of micronutrients.

How it fits into food and nutrition security

• Food security (FAO, World Food Summit 1996): all people, at all times, can physically reach and afford enough safe, nutritious food for an active, healthy life.

• It has four pillars: 1. Availability: enough food exists, from production and buffer stocks (grain the government stores for bad years). 2. Access: people can reach food and pay for it. This depends on income and the PDS. 3. Utilisation: the body can actually absorb the food. 4. Stability: all of the above hold steady over time.

• Nutrition security goes further. It needs a balanced diet with both macronutrients and micronutrients, plus clean water, sanitation and healthcare.

• Hidden hunger is mainly a failure of nutrition security and of the utilisation pillar, even where availability and access are met.

What causes it and what reduces it

• What makes it worse:
• Diets based on a few cereals. India's PDS has mostly supplied rice and wheat, so it focuses on calories, not nutrition.
  • MSP buying of rice and wheat → large stocks of these two grains → the PDS gives out mostly these grains → people's diets have too little variety.

• Poor water, sanitation and health. Infections and diarrhoea stop the body from absorbing nutrients, even when the food is good.

• What reduces it:

• Biofortification: breeding crops that naturally carry more micronutrients.
• Fortification: adding micronutrients to common foods, like fortified rice.
• More varied diets: for example, millets, pulses, vegetables.
• WASH (water, sanitation and hygiene), so the body can use what it eats.

Reading the scale: a simple worked example

• NFHS-5 (2019-21) says 67% of children aged 6–59 months are anaemic [3].
• So in a village with 100 such children, about 67 would be anaemic. Only about 33 would not be.
• Many of these children may be eating enough calories. This shows why calorie supply alone does not end hunger.

In India

• How it is measured: NFHS-5 (2019-21) (National Family Health Survey):
• Anaemia (low haemoglobin in the blood, often caused by iron deficiency):
  • 57% of women aged 15–49 [3]
  • 67% of children aged 6–59 months [3]
  • 52% of pregnant women [3]

• 35.5% of children under 5 are stunted (too short for their age, a sign of long-term undernutrition).

• Fortified rice (normal rice mixed with kernels that carry added iron, folic acid and vitamin B12):

• The CCEA (Cabinet Committee on Economic Affairs) approved a phased roll-out in April 2022.
• Universal coverage across TPDS, ICDS, PM POSHAN and other welfare schemes was reached by March 2024 [3].
• About 406 lakh tonnes were distributed from 2019-20 to 31 March 2024 [3].

• In October 2024, the Cabinet approved continuing free fortified rice from July 2024 to December 2028 [2].

• Biofortification by ICAR (Indian Council of Agricultural Research):

• Examples: zinc-rich wheat and iron-rich pearl millet (bajra).

• 109 varieties were released in 2024.

• The legal and scheme base:

• NFSA 2013 gives grain, plus meals and take-home rations for children through ICDS (anganwadis) and mid-day meals (now PM POSHAN).

• It also gives a maternity benefit of at least ₹6,000 to pregnant women and breastfeeding mothers (Section 4) [1].

• Jan Poshan Kendras: a pilot to turn 60 fair price shops into outlets that also sell other nutritious food (2024) [4].

• Global Hunger Index (GHI): India was 105th of 127 in 2024, rated "serious". The government disputes the method (verify latest).

Don't confuse with

• Undernourishment (calorie hunger): not eating enough calories. Hidden hunger is a lack of micronutrients, even when calories are enough. Undernourishment is a GHI indicator. Anaemia is not.
• Stunting vs wasting: stunting is low height for age, a sign of long-term undernutrition. Wasting is low weight for height, a sign of recent, sudden undernutrition. Both are GHI indicators.
• Biofortification vs fortification: biofortification breeds the nutrient into the crop while it grows (for example, zinc-rich wheat). Fortification adds nutrients to food after harvest (for example, fortified rice kernels).
• Food security vs nutrition security: food security is about enough, safe, nutritious food for all at all times. Nutrition security stresses a balanced diet with micronutrients plus clean water, sanitation and health so the body can use it. Hidden hunger can exist even where food security looks fine.

Prelims Hooks

• Hidden hunger = a lack of micronutrients (iron, zinc, iodine, vitamin A) despite adequate calorie intake.
• NFHS-5 (2019-21) anaemia: 57% of women (15–49), 67% of children (6–59 months), 52% of pregnant women [3]. Stunting among children under 5 is 35.5%.
• Fortified rice carries iron + folic acid + vitamin B12. It is not zinc or vitamin A. It became universal in government schemes by March 2024 [3] and will continue to December 2028 [2].
• Trap: the GHI uses four indicators: undernourishment, child stunting, child wasting and under-5 mortality. Anaemia is NOT a GHI indicator.
• ICAR's biofortified crops include zinc-rich wheat and iron-rich bajra. 109 varieties were released in 2024.
• Four pillars of food security (FAO 1996): availability, access, utilisation, stability. "Sovereignty" is not a pillar. Hidden hunger links most closely to utilisation.

Mains Points

• From calorie security to nutrition security (GS-II/III):
• The PDS was built on rice and wheat bought at MSP. It largely solved calorie hunger, but 57% of women are still anaemic (NFHS-5) [3].

• A strong answer links fortified rice, biofortified varieties, millets in the PDS, ICDS and PM POSHAN, and WASH under the "utilisation" pillar.

• MSP–PDS link and crop diversity (GS-III):

• Open-ended MSP buying of rice and wheat → too much of these two grains → the PDS diet has little variety → micronutrient gaps remain.

• Adding millets and pulses to the PDS helps nutrition. It also helps crop diversification and saves groundwater, and it supports food sovereignty (people choosing local, culturally suitable food).

• Measurement debate (GS-II):

• India ranked 105th of 127 on the GHI 2024 ("serious"). The government argues that 3 of the 4 indicators measure only children and that undernourishment comes from a small opinion-poll sample.
• Whatever the ranking, NFHS-5 data on anaemia and stunting show that hidden hunger is a real problem. Fortification alone is not enough without better diets, sanitation and health services.
