Nutrition
Nutrition and food safety are two sides of the same coin: food must be both safe and nourishing. This hub covers the intersection — nutrition labeling rules, nutrient analysis, and the safety issues that arise where nutrition meets processing, from allergen labeling to infant formula standards.
In the United States, the FDA’s Nutrition Facts label — updated in 2016 with larger calorie type, added sugars, and revised serving sizes — is mandatory on most packaged foods under 21 CFR 101.9. Behind the label sits analytical chemistry: protein by Kjeldahl or Dumas, fat by extraction, vitamins by HPLC. Get the analysis wrong and the label misleads millions.
Safety and nutrition also collide in formulation: reducing sodium or sugar changes water activity and pH, which changes microbial risk. Reformulation without revalidating safety is how good intentions become recalls. Explore the quizzes and articles below with that link in mind.

Frequently Asked Questions
What changed on the US Nutrition Facts label?
The 2016 update (mandatory from 2020/2021): larger calories, “added sugars” line, updated serving sizes reflecting actual consumption, dual-column for multi-serving packages, and revised daily values.
How are nutrition facts verified?
Through laboratory analysis (protein, fat, vitamins, minerals) and/or database calculation from ingredient data. FDA can and does check — significant deviations trigger enforcement.
Why does reformulation affect food safety?
Cutting salt, sugar, or fat alters water activity, pH, or both — the hurdles keeping microbes in check. Any meaningful reformulation should trigger a fresh hazard review.
What was the melamine scandal?
In 2008, melamine was added to milk in China to fake higher protein readings on nitrogen-based tests. It caused kidney damage in hundreds of thousands of infants and led to global tightening of protein testing methods.
