Front-of-pack warning labels are a tool for consumer empowerment, but their efficacy depends on scientifically sound thresholds. Discuss with reference to the ongoing Supreme Court case on FSSAI's labelling norms.

Front-of-pack (FOP) labelling converts dense nutrition tables into a single visual cue, enabling an informed choice at the point of purchase. FSSAI's proposed red hexagonal warning for packaged foods high in added sugar, salt or fat [1] makes this a live issue, but the Supreme Court's questioning of how "high" is defined shows that the tool is only as credible as the science behind its cut-offs.

FOP labels as consumer empowerment

• Right to know: a warning symbol communicates risk to low-literacy and rural consumers who cannot decode per-100g values — visual cues work where numbers do not.
• Behavioural nudge: warnings shift choices without banning products, preserving consumer autonomy while addressing India's rising non-communicable disease burden; ICMR-NIN's Dietary Guidelines for Indians, 2024 explicitly advise restricting salt, added sugar, high fat and ultra-processed foods [2].
• Existing precedent: the Labelling and Display Regulations already mandate prominent warnings, such as the statutory caution on supari packs [3], showing the regulatory template exists.
• Industry reformulation: the prospect of a warning label pushes manufacturers to cut sugar and salt content pre-emptively.

Why thresholds decide efficacy

• A Bench of Justices J.B. Pardiwala and K. Vinod Chandran asked FSSAI whether guidelines exist for classifying a food as "high", with the Centre stating that ICMR-NIN norms would supply the benchmark [1].
• Lax cut-offs would leave most products unlabelled, making the symbol meaningless; arbitrary ones invite litigation for being unreasonable subordinate rule-making.
• WHO's guiding principles require FOP systems to be government-led and evidence-informed, tested for consumer comprehension [4].
• The Court's earlier probing of whether industry pressure shaped FSSAI's reluctance underlines the need for transparent, insulated standard-setting [1].

Thus, the label is the messenger and the threshold is the message. FSSAI should notify ICMR-NIN-anchored, category-wise cut-offs with published scientific reasoning, a phased compliance window for small processors, and consumer-comprehension testing. Judicially nudged and scientifically grounded, FOP warnings can advance the Article 21 promise of health alongside SDG-3.
