Research
How many packaged foods are "low sodium"? 183,448 of 396,217 packaged products (46%) are at or under FDA's "low sodium" line per labeled serving: 140 mg or less (per 50 g as well when the serving is 30 g or less), or per 100 g for meal and main-dish products. FDA tests per reference amount, which most labeled servings follow; the count is not a finding that any label complies. In the frozen breakfast sandwiches aisle it is 0%, in bacon 0% and in frozen pizza 0%; in 16 of 68 aisles it is 90% or more.
How much sugar is in yogurt, by style? Across 5,381 yogurts in USDA's branded database, flavored regular yogurt has the most sugar, a median of 11.1 g per 100 g; plain plant-based yogurt the least, 0.7 g. Weighted by products, flavored yogurts carry about 10.2 g per 100 g against 4.2 g for plain ones.
How many serving sizes does one kind of food have? In the frozen meals aisle, 4,952 products declare 346 different serving sizes: one in ten is 113 g or less and one in ten 312 g or more. The most common size, 255 g, is on 11% of labels. Comparing two products per serving can mean comparing different amounts of food; per 100 g, it cannot.
