A strawberry yogurt drink can be legal in Mumbai, Munich, and Miami while telling three different stories on the package. The US foregrounds added sugars on the Nutrition Facts label. The EU makes many additives visible by function plus name or E number. India places much of the rulebook under FSSAI. Same shelf mood. Different legal grammar.

Food-label research is not a claim that one word causes disease. It is evidence about attention and interpretation. Kaur, Scarborough, and Rayner published a 2017 systematic review and meta-analysis in the International Journal of Behavioral Nutrition and Physical Activity, reviewing 31 papers and meta-analysing 17. They reported that health and nutrition claims were associated with a higher likelihood of choosing products carrying claims.6
Oostenbach et al. published a 2019 systematic review in BMC Public Health covering 11 studies. The review found that nutrition claims can shift perceived healthfulness, expected taste, portion-size judgments, and energy estimates. That is label perception, not long-term diet outcome data. Cowburn and Stockley reviewed 103 papers in Public Health Nutrition in 2005 and found the familiar gap: people say they read labels, but objective understanding and use are uneven.6
This is why regulators matter. They do not make a food "clean." They set the grammar for what has to be disclosed, how claims can be worded, and which details are prominent enough for a normal shopper to notice.
Evidence Snapshot
The Global Rule, And The Small Print
Sets model standards for prepackaged food labels, including ingredient naming, ordering, and misleading presentation. Codex guides national law; it does not enforce your local package.
FDA covers most foods and requires added sugars on the Nutrition Facts label. USDA-FSIS handles meat, poultry, and certain egg products.
FSSAI is the central authority for standards, licences, additives, labels, claims, imports, and enforcement support across a very large market.
EFSA assesses scientific risk. The European Commission and Member States manage rules and enforcement, including additive authorisation and food-information law.

Regulators are safety systems, not personal shoppers. A permitted additive is not automatically a problem. A short ingredient list is not automatically safer. "No preservatives" can still mean high sugar, sterile processing, or packaging that does the preserving quietly.
The other catch is enforcement. A rule on paper depends on testing, inspections, recalls, penalties, courts, and consumer complaints. The EU separates risk assessment and risk management clearly. The US has a more flexible route because some GRAS conclusions can operate without premarket FDA approval. India looks unified because FSSAI is central, but enforcement is shared across systems.
Pick one packaged drink, bar, or snack and read it in three passes. First, name the ingredient functions: sweetener, flavour, emulsifier, stabiliser, colour, preservative. Second, circle the claims: natural, pure, no added sugar, immune, high protein, heart healthy. Third, check whether the ingredient list and nutrition panel support the front-panel mood. If they do not, the label may still be legal, but it can be harder to interpret.
