- Massive giant exoplanets are defined as those with a mass greater than four times that of Jupiter.
About the Exoplanet TOI4603b
- The exoplanet is found around the star called TOI4603 or HD 245134.
- It has a mass 13 times greater than that of Jupiter and a density of approximately 14 g/cm3.
- Initially, NASA’s Transiting Exoplanet Survey Satellite (TESS) declared TOI4603 as a possible candidate to host a secondary body of unknown nature.
- Using PARAS, scientists confirmed the secondary body as a planet, and it was named TOI 4603b or HD 245134b.
- The exoplanet is located 731 light years away and orbits a sub-giant F-type star TOI4603 every 7.24 days.
Note: An exoplanet, short for “extra-solar planet,” is a planet that orbits a star other than our Sun. These planets are located outside of our solar system and are not part of our planetary system.
Unprecedented Density and Proximity
- TOI 4603b is one of the most massive and densest giant planets discovered to date.
- It orbits very close to its host star at a distance less than 1/10th the distance between our Sun and Earth.
- Comparisons between the TOI-4603 star-planet system and the Sun-Mercury and Sun-Jupiter systems highlight the close proximity of TOI-4603 b to its star.
- The exoplanet is situated more than 50 times closer to its star than Jupiter is to the Sun.
- TOI-4603b is 13 times more massive than Jupiter.
Utilization of Indigenous Technology
- The discovery of this massive exoplanet was made using the indigenously made PRL Advanced Radial-velocity Abu-sky Search spectrograph (PARAS) at the 1.2 m telescope of PRL at its Gurushikhar Observatory in Mt. Abu.
- The mass of the planet was measured precisely using PARAS.
Uniqueness of the Discovery
- The planet falls into the transition mass range of massive giant planets and low-mass brown dwarfs, with masses ranging from 11 to 16 times the mass of Jupiter.
- Only fewer than five exoplanets are currently known in this mass range.
- The rarity of such discoveries makes this finding significant.
Insights into Formation and Evolution
- The exoplanet has a surface temperature of 1670 K and is likely undergoing high-eccentricity tidal migration with an eccentricity value of approximately 0.3.
- The detection of such systems provides valuable insights into the formation, migration, and evolution mechanisms of massive exoplanets.
India’s Contribution to Exoplanet Discoveries

From UPSC perspective, the following things are important :
Prelims level: Chytridiomycosis
Mains level: Not Much

Central Idea
- A multinational study has recently published a breakthrough method in the journal Transboundary and Emerging Diseases to detect all known strains of the amphibian chytrid fungus.
- This method will enhance our ability to detect and research the disease and work towards finding a widely available cure.
Chytridiomycosis: The deadly frog disease
- Chytridiomycosis, also known as chytrid, is a fungal disease that has been decimating frog populations worldwide for the past 40 years.
- The disease has caused severe declines in over 500 frog species and led to 90 extinctions, making it the deadliest animal disease known.
How does it infect?
- Chytrid infects frogs by reproducing in their skin, damaging their ability to balance water and salt levels.
- The mortality rate is extreme, and the disease has affected a high number of species, causing devastating declines and extinctions.
- The disease originated in Asia and spread globally through amphibian trade and travel.
Limitations in diagnosis
- Researchers traditionally used swabs and quantitative polymerase chain reaction (qPCR) tests, similar to COVID-19 testing, to detect chytrid in frogs.
- The existing qPCR test could not detect chytrid strains from Asia, limiting research efforts.
New and Improved qPCR Test
- Researchers in India, Australia, and Panama have developed a new qPCR test that can detect strains of chytrid from Asia.
- The test is also more sensitive, allowing for the detection of low infection levels and expanding the range of species that can be studied.
- The test can also detect a closely related species of chytrid that infects salamanders.
Understanding natural immunity in frogs
- Some amphibian species, even those without an evolutionary history with chytrid, do not become sick when carrying the fungus, indicating natural immune resistance.
- Frog immunity is complex, involving anti-microbial chemicals, symbiotic bacteria, white blood cells, antibodies, and more.
- Research in Asia, where chytrid declines have not been observed, may provide insights into how resistance evolves and aid in finding a cure for affected regions.

From UPSC perspective, the following things are important :
Prelims level: OROP, Agniveer scheme
Mains level: One Rank One Pension challenges and way forward

Central Idea
- In recent times, two prominent ideas, right-sizing and Atmanirbharta, have gained traction in the Armed Forces. However, it is essential to recognize that both these initiatives have their shortcomings and are rooted in the flawed implementation of the One Rank One Pension (OROP) scheme. These policies have far-reaching consequences and necessitate a critical evaluation to ensure the long-term sustainability and effectiveness of our armed forces
What is One Rank One Pension (OROP) Policy?
- OROP means the same pension, for the same rank, for the same length of service, irrespective of the date of retirement.
- The concept was provoked by the then decision by Indira Gandhi-led government, in 1973, two years after the historic victory in the 1971 Bangladesh war
Implications of OROP
- Enhanced Pension Benefits: OROP brings parity and fairness by addressing the concerns of veterans who felt their pensions were unjustly lower compared to their counterparts who retired earlier. This leads to improved financial security for retired armed forces personnel and their families.
- Motivation and Morale: OROP addresses long-standing grievances regarding pension disparities and recognizes the sacrifices made by veterans. The assurance of fair and equal pensions enhances the sense of dignity, honor, and respect for those who have served in the armed forces.
- Social Security: OROP enhances the financial security and social welfare of retired armed forces personnel and their families. It provides them with a stable and predictable income during their post-retirement years, ensuring a decent standard of living and supporting their well-being
- Financial Burden: OROP entails providing equal pension benefits to all military personnel retiring at the same rank with the same length of service, irrespective of their date of retirement. This results in an increased financial burden on the government, as it has to allocate additional funds to fulfill the pension requirements.
- Impact on Modernization: The financial implications of implementing OROP may impact the allocation of funds for modernization and procurement of advanced equipment and technologies. The increased pension expenditure could limit the resources available for upgrading the armed forces’ capabilities, affecting their preparedness and modernization efforts.
- Sustainability and Budgetary Constraints: Sustaining the OROP scheme in the long term poses challenges due to the increasing pension liabilities. The government needs to ensure that the pension system remains financially viable and sustainable, considering the rising life expectancy and the expanding pool of retired armed forces personnel.
Challenges in Rightsizing and Strategic Decision-making
- Improved Insurgency Situation: The considerably improved insurgency situation in Jammu and Kashmir, particularly south of Banihal, has prompted a reassessment of force requirements. While progress has been made in countering militancy, the dilution of manpower without compensatory measures, such as state-of-the-art equipment, poses challenges to sustaining effective counter-insurgency operations.
- The Northeast and Counter-insurgency: The transfer of counter-insurgency responsibilities from the Army to the Assam Rifles in the Northeast region represents a significant shift. While relieving the Army of secondary responsibilities is reasonable, reducing combat strength without adequate compensation in terms of advanced equipment may impact the effectiveness of operations, particularly in regions with ongoing ethnic conflicts like Manipur.
Zero Recruitment and Adverse Impact
- Manpower Deficiency: The absence of recruitment for two-and-a-half years until June 2022 has created significant voids in personnel strength, particularly affecting combat units. The mounting deficiencies, amounting to 1,80,000 personnel in the Army alone, have strained operational capabilities and increased the burden on existing forces.
- Combat Readiness and Strategic Concerns: The adverse impact of zero recruitment and constant personnel retirements has had serious repercussions on combat units, including those deployed in sensitive areas like Ladakh against the Chinese PLA.
Way ahead: Need for Rightsizing and Strategic Evaluation
- Effective Allocation of Resources: Rightsizing involves optimizing the allocation of resources, including manpower, equipment, and finances, to ensure efficiency and effectiveness. It helps in aligning the available resources with the desired objectives and operational requirements.
- Enhanced Operational Readiness: By conducting a strategic evaluation, the armed forces can assess their current capabilities and identify areas for improvement. This evaluation helps in identifying gaps and addressing them to enhance operational readiness and combat effectiveness.
- Financial Sustainability: Rightsizing allows for a more sustainable financial model by ensuring that the allocated funds are utilized efficiently. It helps in managing the budgetary constraints and reducing unnecessary expenditures, allowing resources to be redirected towards critical areas such as modernization and technological advancements.
- Adapting to Changing Threat Landscape: Strategic evaluation helps in assessing the evolving security threats and challenges faced by the nation. It enables the armed forces to adapt and realign their structure, capabilities, and operational concepts to effectively counter emerging threats and maintain a credible deterrence posture.
- Optimal Utilization of Human Resources: Rightsizing involves assessing the manpower requirements and aligning them with the operational needs. It helps in ensuring that the armed forces have the right personnel in the right positions, adequately trained and equipped to fulfill their roles and responsibilities.
- Modernization and Technological Upgrades: Strategic evaluation provides an opportunity to prioritize modernization initiatives and technological upgrades. It enables the armed forces to invest in cutting-edge equipment, systems, and platforms that enhance their combat capabilities and maintain technological superiority.
- Operational Flexibility and Agility: Rightsizing and strategic evaluation enable the armed forces to achieve operational flexibility and agility. It allows for the formation of versatile and adaptable units, capable of responding to a wide range of contingencies and operating in diverse environments.
- Long-Term Sustainability: By aligning the force structure, resources, and operational requirements, rightsizing and strategic evaluation contribute to the long-term sustainability of the armed forces. It ensures that the military remains capable and resilient, able to meet the nation’s security needs effectively
Conclusion
- While the ideas of right-sizing and Atmanirbharta may seem appealing, it is crucial to critically analyze their implementation and potential ramifications. The flawed execution of the OROP scheme and subsequent policies have placed a burden on the Armed Forces, affecting their modernization efforts. It is imperative to strike a balance between optimizing resources and ensuring the security and preparedness of our forces.

From UPSC perspective, the following things are important :
Prelims level: Role of CJI and related constitutional provisions
Mains level: Administrative powers of the CJI, challenges and concerns
Central Idea
- A recent judicial development has raised concerns about the authority and powers of the Chief Justice of India (CJI) in influencing judicial decisions. The recall application filed by the Union of India against a judgment regarding the right to default bail, followed by an interim order from the Court of the CJI, has highlighted the need to reassess the constitutional framework and the extent of the CJI’s administrative powers
An Extraordinary Decision and its Unusual Turn
- Safeguarding the Right to Default Bail: The Division Bench of the Supreme Court in Ritu Chhabria v. Union of India recognized the right of an undertrial to be released on default bail if the investigation exceeds the statutory time limit. It criticized the practice of charge-sheeting accused individuals despite incomplete investigations and emphasized that the filing of a preliminary charge-sheet does not extinguish the right to bail.
- Surprising Recall Application: The Court of the CJI entertained a recall application filed by the Union of India against the Ritu Chhabria judgment. This move deviated from the usual course of filing a review petition before the same Bench. The interim order passed by the Court of the CJI effectively stayed the Division Bench’s decision, even though it had no direct connection to the case.
Concerns over the Role of the CJI
- Intra-court Appeal without Legislative or Constitutional Backing: The recall application before a different Bench, including the CJI, raises concerns about the absence of a legislative or constitutional framework for such appeals. This practice can be seen as bench fishing or forum shopping, creating a mechanism devoid of legal legitimacy.
- The CJI’s Administrative Powers: While all Supreme Court judges possess equal judicial powers, the CJI enjoys special administrative powers as the ‘Master of the Roster.’ These powers include constituting Benches and assigning matters for reconsideration. However, within a Bench, the CJI’s vote holds no greater weight than that of other judges.
- Issues of Judicial Equality: While historically, the CJI has authored minority opinions, the recent interim order raises concerns about the extent of the CJI’s influence on judicial decisions. Other countries, such as the United Kingdom, Australia, and Canada, have systems where judges collectively exercise power, reflecting the collective strength of the Court.
Cause for Concern
- Instances of Abuse: Recorded instances of infirmities and irregularities in case assignments have raised concerns about the potential abuse of administrative powers by the CJI. The unending nature of these powers makes it impractical to establish limits, emphasizing the need for transparency and checks.
- The Need for Checks and Balance: To maintain the integrity of the judiciary, it is crucial to limit the expansion of the CJI’s powers as the ‘Master of the Roster.’ The computerization of case assignments and the removal of discretionary powers from the CJI can mitigate concerns of undue influence and ensure a fair and impartial judicial process.
Administrative Powers of the CJI
- Constitution of Benches: The CJI has the authority to constitute various Benches within the Supreme Court, including both Division Benches and larger Constitution Benches. This power allows the CJI to assign judges to specific cases and distribute the workload among the judges.
- Assignment of Matters: The CJI has the discretion to assign specific cases or references to different Benches for adjudication. This includes allocating matters to the appropriate Benches based on subject matter, complexity, and other relevant factors.
- Reconsideration of Matters: The CJI can refer cases or issues for reconsideration by a larger Bench. This power enables the CJI to ensure consistency in judicial pronouncements, resolve conflicting decisions, or clarify legal principles through the review of previous judgments.
- Administrative Decision-Making: The CJI is responsible for making administrative decisions related to the court’s functioning, including the allocation of courtrooms, assignment of court staff, and management of infrastructure and resources.
- Appointment of Judicial Officers: The CJI plays a significant role in the appointment and transfer of judges to various high courts and other tribunals. This responsibility includes participating in the collegium system, which involves recommending suitable candidates for judicial appointments.
- Judicial Administration: The CJI oversees the overall functioning of the judiciary, including setting standards for court procedures, case management, and promoting efficiency in the delivery of justice. The CJI works closely with other judges, court officials, and stakeholders to ensure the smooth operation of the judicial system
Facts for prelims
Key provisions related to the CJI’s administrative authority
- Article 145: This article enables the CJI, as the head of the court, to exercise administrative control over the functioning of the Supreme Court.
- Article 146: This article empowers the CJI to appoint officers and servants of the Supreme Court and to determine their conditions of service. It allows the CJI to administer the court’s staff and resources in order to ensure efficient administration.
- Article 147: This article establishes the authority of the CJI in matters related to the appointment and posting of officers and servants of the Supreme Court. The CJI has the power to determine the strength and composition of the court’s administrative staff.
- Article 229: This article deals with the appointment of retired judges of the Supreme Court and high courts to act as ad-hoc judges. The CJI plays a significant role in appointing and assigning duties to these ad-hoc judges, which contributes to the efficient functioning of the judiciary.
- Article 124(3): This provision relates to the appointment of judges to the Supreme Court. The CJI, as part of the collegium system, participates in the process of recommending suitable candidates for judicial appointments. The collegium consists of the CJI and a group of senior judges, and their recommendations play a crucial role in judicial appointments.
|
Conclusion
- While the administrative powers of the CJI are necessary for the efficient functioning of the Court, their exercise should adhere to constitutional principles and established legal procedures. It is imperative to establish transparent systems and minimize discretionary powers to safeguard the integrity and impartiality of the judiciary.

From UPSC perspective, the following things are important :
Prelims level: 17th Lok Sabha performance and related facts
Mains level: Low performance of 17th Lok Sabha, concerns and way forward

Central Idea
- India’s new Parliament building, inaugurated by Prime Minister Narendra Modi, symbolizes the aspirations of 140 crore Indians. However, as the 17th Lok Sabha nears its final year, it faces scrutiny over its performance.
Performance of 17th Lok Sabha
- Sitting Days: The 17th Lok Sabha has functioned for 230 sitting days so far. However, if it falls short of surpassing the lowest recorded full-term Lok Sabha (331 sitting days in the 16th Lok Sabha), it would become the shortest full-term Lok Sabha since 1952.
- Referral of Bills to Committees: There has been a decline in the referral of bills to Parliamentary Standing Committees. Since 2004, only 45% of the total bills introduced in Parliament have been referred to committees. This suggests a potential decrease in comprehensive scrutiny and review of proposed legislation.
- Legislative Output: The number of bills introduced and passed in the 17th Lok Sabha has seen a decline. Out of the 150 bills introduced, 131 have been passed so far (excluding Finance and Appropriation Bills). The decreasing trend raises questions about the legislative productivity of the Lok Sabha.
- Budget Discussions: The latest Budget session of the 17th Lok Sabha was one of the shortest since 1952. The limited time dedicated to discussing financial matters, particularly the Budget, raises concerns about the depth of analysis and deliberation on critical fiscal issues.
- Debates on Matters of Public Importance: The number of debates conducted in the Lok Sabha during the tenure of the 17th Lok Sabha has been limited. There have been only 11 short duration discussions and one half-an-hour discussion, indicating a restricted avenue for robust parliamentary discourse on matters of public importance.
- Delayed Election of Deputy Speaker: Despite the constitutional provision mandating the election of a Deputy Speaker, the 17th Lok Sabha has not elected one, even as it enters its final year of the five-year term. This delay raises concerns about adherence to constitutional norms and the effective functioning of parliamentary proceedings.

Why the 17th Lok Sabha’s productivity has been low?
- Disruptions and Protests: The 17th Lok Sabha witnessed frequent disruptions and protests from opposition parties, leading to a significant loss of time and decreased productivity. Some of the major issues that led to disruptions include the Citizenship Amendment Act (CAA), National Register of Citizens (NRC), and farm laws.
- Lack of Consensus: The ruling party enjoyed a clear majority in the Lok Sabha, but there was still a lack of consensus on many key issues, resulting in a delay in passing important bills and legislation.
- COVID-19 Pandemic: The COVID-19 pandemic also contributed to the low productivity of the Lok Sabha as many sessions were delayed or cancelled due to safety concerns.
- Speaker’s Decision: The decision of the Speaker of the Lok Sabha to disallow opposition MPs from raising certain issues also resulted in protests and disruptions, further reducing the productivity of the house.
- Shorter Sessions: The 17th Lok Sabha had shorter sessions compared to previous Lok Sabhas, which also contributed to lower productivity. Many important bills and issues were left pending as there was not enough time to discuss and debate them thoroughly.
The concerns associated with the performance of MPs in the old Parliament building
- Limited Parliamentary Engagement: The limited number of sitting days raises concerns about the MPs’ ability to fully engage in legislative proceedings and address the various challenges and issues faced by the country.
- Decreased Scrutiny of Legislation: The declining referral of bills to Parliamentary Standing Committees raises concerns about the thorough scrutiny and review of proposed legislation.
- Legislative Productivity: The decreased number of bills introduced and passed in the 17th Lok Sabha raises concerns about its legislative productivity. This may limit the ability of MPs to address critical issues, propose new policies, and enact necessary reforms, hindering progress and development.
- Limited Budget Discussions: The shortened Budget sessions and reduced time allocated for financial discussions raise concerns about the depth of analysis and deliberation on critical fiscal matters.
- Restricted Debates on Public Matters: The limited number of debates conducted in the Lok Sabha raises concerns about the comprehensive discussion and examination of matters of public importance.

New Parliament Building: An Opportunity for Efficiency

From UPSC perspective, the following things are important :
Prelims level: AISHE
Mains level: Religious disparity in higher education

Central Idea
- All India Survey on Higher Education (AISHE) 2020-21 conducted by the Ministry of Education reveals the underrepresentation of Muslims in higher education compared to other communities.
What is the AISHE?
- To portray the status of higher education in the country, the Ministry of Education conducts an annual web-based AISHE since 2010-11.
- Data is collected on several parameters such as teachers, student enrolment, programmes, examination results, education finance and infrastructure.
- Indicators of educational development such as Institution Density, Gross Enrolment Ratio, Pupil-teacher ratio, Gender Parity Index, Per Student Expenditure will also be calculated from the data collected through AISHE.
- These are useful in making informed policy decisions and research for development of the education sector.
AISHE 2020-21 data on Minority Education
The survey highlights a decline in Muslim enrollment, potentially due to economic constraints and limited opportunities for pursuing higher education.
(1) Decline in Muslim Enrollment:
- Muslim enrollment in higher education declined by 8% in the 2020-21 academic year, while other marginalized communities experienced improved enrollment rates.
- Economic impoverishment forces talented Muslim students to prioritize earning opportunities after completing school, rather than pursuing higher education.
- Drastic declines were reported in UP (36%), J&K (26%), Maharashtra (8.5%), and TN (8.1%).
- Delhi witnessed a significant portion of Muslim students failing to enroll for higher education.
(2) Uttar Pradesh’s Low Enrollment Rate:
- Muslims constitute around 20% of the population in the state.
- Despite an increase in the number of colleges in UP, mere 4.5% Muslim enrollment is in higher education.
(3) Kerala’s Exceptional Performance:
- Kerala stands out as the only state where 43% of Muslims pursue higher education, bucking the trend of low enrollment.
(4) Female enrolment improving:
- Muslim and other minority communities exhibit higher female student enrollment than male students, indicating progress for women in minority communities.
- Male members of the Muslim community face pressure to earn a living early, potentially hindering their pursuit of higher education.
(5) Lack of Muslim Teachers:
- Muslim representation among teachers in higher education institutions is alarmingly low, comprising only 5.6%.
- General Category teachers account for 56%, while OBC, SC, and ST teachers make up 32%, 9%, and 2.5%, respectively.
- Gender disparities among teachers persist, with only 59 female Muslim teachers for every 100 male Muslim teachers.
Reasons for such low enrollment
- Religious influence: Certain societal and cultural norms within the Muslim community prioritize early marriage and family responsibilities over pursuing higher education, especially for female students.
- Economic Challenges: The Muslim community faces financial limitations that hinder their ability to afford higher education expenses, including tuition fees and accommodation.

From UPSC perspective, the following things are important :
Prelims level: Overturning Circulation
Mains level: Not Much

Central Idea
- Recent research indicates that the Antarctic overturning circulation, a global network of ocean currents, is slowing down at a faster rate than previously predicted.
- The overturning circulation is crucial for redistributing heat, carbon, and nutrients, and maintaining Earth’s climate stability and deep-ocean oxygen levels.
What is Overturning Circulation?
- The overturning circulation (OC) refers to the large-scale circulation pattern in the global ocean, involving both surface and deep currents.
- It is a network of ocean currents that plays a crucial role in redistributing heat, carbon, and nutrients around the globe.
- It is driven by the sinking of dense, cold, oxygen-rich water from the ocean surface to the deep ocean and the rising of less dense water in different regions.
How does it work?
- It operates on a global scale and involves the sinking and rising of water masses driven by density differences.
- Cold, dense water sinks in certain regions, while warmer, less dense water rises in other areas, creating a continuous flow of water.
Key components and processes
- Antarctic Bottom Water: Cold, dense water forms near Antarctica and sinks to the ocean floor, spreading northward along the seafloor.
- North Atlantic Deep Water: Another dense water mass forms in the North Atlantic and sinks to great depths.
- Thermohaline Circulation: Temperature and salinity differences drive the sinking and rising of water masses, influencing the overturning circulation.
- Deep Ocean Currents: Once the dense water sinks, it flows along the deep ocean basins, connecting various regions of the world ocean.
Observing and studying the OC
- Monitoring the overturning circulation is challenging due to its vast scale and complex dynamics.
- Observations include ship-based measurements, moored instruments, floats, satellites, and numerical models.
- Scientists use a combination of measurements and simulations to understand the behavior and changes in the overturning circulation.
Importance of the Overturning Circulation
- Heat redistribution: The overturning circulation helps regulate Earth’s climate by transporting heat from the equator to the poles and vice versa.
- Assist carbon cycle: It plays a vital role in redistributing carbon dioxide and other greenhouse gases, impacting the global carbon cycle.
- Nutrient cycling: The circulation also facilitates the transport of nutrients, affecting marine ecosystems and productivity.
Consequences of a Slowing OC
- Climatic changes: A slowdown in the overturning circulation can have significant consequences for Earth’s climate and marine ecosystems.
- Nutrient disruption: It can disrupt the transport of heat, carbon, and nutrients, leading to changes in regional and global climate patterns.
- De-oxygenation: Reduced oxygen supply to the deep ocean can affect deep-sea marine life and potentially lead to shifts in species distribution.
Impact of Melting Antarctic Ice
- Melting Antarctic ice disrupts the formation of Antarctic bottom water, a key component of the overturning circulation.
- Freshening of surface waters due to melt-water makes them less dense and less likely to sink, slowing down the circulation.
Future Outlook
- Antarctica’s ice loss is expected to continue and accelerate with global warming.
- Anticipated freshening due to increased ice loss will prolong the slowdown and further decrease deep-ocean oxygen levels.
- The consequences of the slowdown extend beyond Antarctica, affecting the global ocean, climate change, and sea level rise.
- Urgent action to reduce greenhouse gas emissions is necessary to address these issues.
Way forward
- Intensify efforts to reduce greenhouse gas emissions.
- Implement measures to mitigate ice loss from Antarctica and address the freshening of surface waters.
- Promote scientific research and monitoring to understand and respond to the ongoing changes.
- Raise awareness about the importance of the overturning circulation and its impact on climate and marine ecosystems.

From UPSC perspective, the following things are important :
Prelims level: Iron fortification
Mains level: Read the attached story

Central Idea
- Iron is an essential mineral for bodily functions, but excessive intake can be harmful.
- Fortification of food with iron is a suggested method for treating iron deficiency anemia.
- Excess consumption of fortified foods or simultaneous consumption of multiple fortified foods can lead to excessive iron intake.
What is Iron Fortification?
- Iron fortification refers to the process of adding iron to food products to increase their iron content.
- It is done using various forms of iron, such as iron salts or iron powders, which are added to the food during processing.
- It is a public health strategy employed to address iron deficiency, particularly in populations where inadequate iron intake is prevalent.
- The goal is to provide a significant portion of the recommended daily iron intake through fortified foods, contributing to the prevention and treatment of iron deficiency anaemia.
Implications for Iron Overload
- Comorbidities: Iron overload conditions, such as thalassemia, hemochromatosis, and chronic liver disease, have impaired iron excretion mechanisms.
- Blooding events: Iron absorption is balanced by steady and minimal excretion, except during bleeding events.
- Menstrual bleeding: Women can excrete iron through menstrual bleeding, while men are less capable of iron excretion.
- Oxidative stress: Increased iron intake can lead to oxidative stress, cellular damage, and impaired mitochondrial function.
- Heart ailments: High serum ferritin levels (a marker of iron storage) are associated with an increased risk of chronic diseases such as high fasting serum glucose, high total cholesterol, high triglycerides, and hypertension.
- Liver damage: Very high amounts of iron can activate hepatic stellate cells and cause excessive deposition of extracellular matrix in the liver. Prolonged liver iron overload can lead to liver fibrosis and cirrhosis.
Challenges and consequences
- Minimal absorption: Only a small percentage of ingested iron from fortified foods is absorbed, with the rest passing through the intestine.
- Digestive issues: Unabsorbed iron can cause inflammation in the gastrointestinal lining and disrupt the colonic microbiota, leading to abdominal discomfort and gastrointestinal issues.
- Issues with nutrition absorption: Excessive iron in the gastrointestinal tract can impair the absorption of other essential minerals like zinc and copper and potentially result in other deficiencies.
Way Forward
- Implement individualized strategies for iron intake rather than mandatory fortification programs to avoid unsupervised high iron intake across diverse populations.
- Ensure thorough monitoring and detection of adverse events related to iron intake.
- Precision in public health approaches is necessary to prevent the risk of iron overload and potential long-term chronic illnesses associated with excess iron.
- Evaluate the specific dietary iron needs of different population segments to avoid unnecessary excess iron consumption.
