A recent interim report by the Indian Council of Medical Research (ICMR) has highlighted a concerning link between high selenium concentrations in wheat and hair loss among consumers. The report, based on research conducted at the National Institute of Nutrition (NIN) and the Indian Institute of Millets Research (IIMR), underscores the need for further investigation into selenium levels in food crops and their potential health impacts.
About Selenium Concentration in Wheat
- The ICMR report identifies excessive selenium in soil and irrigation water as the primary cause of high selenium levels in wheat.
- Selenium, a trace element, is naturally present in soil, but its concentration can vary significantly based on geographical location and agricultural practices.
- In certain regions, industrial activities and the use of selenium-rich fertilizers have contributed to elevated selenium levels in crops like wheat.
- The study emphasizes the need for monitoring and regulating selenium levels in agricultural practices to prevent overexposure.
About Selenium and Its Health Implications
- Selenium is an essential micronutrient required for various bodily functions, including thyroid hormone metabolism and antioxidant defense.
- However, excessive selenium intake can lead to toxicity, known as selenosis, which manifests in symptoms such as hair loss, brittle nails, gastrointestinal issues, and neurological abnormalities.
- The ICMR report specifically links high selenium consumption through wheat to hair loss, a condition increasingly observed in certain populations.
- Long-term exposure to elevated selenium levels may also pose risks to liver and kidney health, highlighting the importance of balanced selenium intake.
The ICMR interim report sheds light on a critical issue at the intersection of agriculture and public health. High selenium levels in wheat, driven by environmental and agricultural factors, have been linked to adverse health effects, particularly hair loss. This discovery calls for immediate action, including stricter monitoring of selenium in soil and crops, public awareness campaigns, and further research to understand the full scope of selenium's impact on human health. Addressing this issue is essential to ensure food safety and protect consumer well-being.
