Added Sugars: Older guidelines suggested <10% daily calories; new ones push for near-zero, with a strict cap of 10g/meal, advising avoidance, especially for kids, and banning non-nutritive sweeteners.
Protein: Moved from a minimum (0.8g/kg) to a higher range (1.2-1.6g/kg), encouraging more intake for satiety and displacing processed carbs.
Fats: A significant shift from minimizing all fats (including saturated) to encouraging full-fat dairy and naturally occurring fats, ending the "war on saturated fats".
Processed Foods: New guidelines strongly advise avoiding "highly processed" foods as a category, a significant departure from prior focus on individual nutrients.
Alcohol: Previous limits (1 drink/day women, 2 men) removed, replaced with a general "consume less" message and warnings for vulnerable groups.
Food Labeling: New mandatory front-of-package (FOP) labels for sugar, sodium, and saturated fat, plus updated "healthy" claim definitions (e.g., excluding sweetened cereals).
Microbiome: Introduction of gut health considerations, linking diet to microbiome health.
