I aggregated USDA FoodData Central manganese values across 1,465 foods. 134 cleared 1.0 mg per 100 g, but most U.S. adults already meet the Adequate Intake without trying. Here is what the data says about manganese-rich foods, function, and toxicity risk in 2026.
I aggregated USDA FoodData Central copper values across 1,465 foods. Only 47 cleared 0.5 mg per 100 g, and most are foods Americans skip. Here is what the data says about copper-rich foods, deficiency signs, and intake gaps in 2026.
Biotin (vitamin B7) is needed in tiny daily amounts (30 mcg/day for adults). USDA FoodData Central highlights cooked beef liver, eggs, salmon, sunflower seeds, and almonds as top sources. The 2017 FDA Safety Communication warns that high-dose biotin supplements can interfere with cardiac troponin and thyroid lab tests.
Pantothenic acid (vitamin B5) appears in over 92 percent of foods I have indexed from USDA FoodData Central. Top sources, the NIH adult AI of 5 mg/day, cooking losses, and three sample patterns that meet the AI without supplements.
A data-first look at vitamin B3 (niacin) using USDA FoodData Central nutrient ID 1167: top food sources, the niacin equivalents (NE) calculation, deficiency history (pellagra), and where supplementation cautions actually apply.
An engineer's read of the USDA FoodData Central riboflavin dataset: which foods actually deliver B2, where deficiency risk concentrates in 2026, and what the numbers reveal that listicles miss.
