A recent study by the Indian Council of Agricultural Research (ICAR) has raised concerns about the declining nutritional value of rice and wheat, the staple food for millions in India. The study found that over the past five decades, these major cereals have lost up to 45% of essential nutrients like zinc and iron. This worrying trend coincides with rising deficiencies of these minerals in the Indian population, particularly among women and children.
The decline in nutrient content is attributed to several factors, including:
Focus on high-yielding varieties: Breeding programs have prioritized increased yields over nutritional quality, leading to cereal varieties with lower concentrations of vital minerals.
Depleted soil: Intensive farming practices and overreliance on chemical fertilizers have depleted essential nutrients from the soil, making them less available for plant uptake.
Loss during processing: Milling and polishing processes further strip away valuable nutrients from grains.
The consequences of this nutritional decline can be significant.

Zinc and iron deficiencies are linked to various health problems, including impaired growth and development, weakened immune systems, and increased vulnerability to infections.
In pregnant women, zinc deficiency can lead to complications during childbirth and birth defects in newborns.
While the ICAR study highlights a concerning trend, it's important to note that the situation is not entirely bleak.

Several efforts are underway to address the issue:
Biofortification programs:
Scientists are developing new rice and wheat varieties with higher levels of zinc and iron through biofortification techniques.
Diversification of diets:
Encouraging the consumption of diverse crops rich in these minerals, such as millets, lentils, and leafy vegetables, can help address deficiencies.
Improved soil management practices:
Adopting sustainable agricultural practices like crop rotation, cover cropping, and organic fertilization can help replenish soil nutrients and improve crop quality.
Addressing the declining nutritional value of rice and wheat requires a multi-pronged approach involving farmers, scientists, policymakers, and consumers.

By promoting biofortified varieties, diversifying diets, and adopting sustainable farming practices, India can work toward ensuring that its staple foods remain not just filling, but also nourishing for its population.
