Hamburger — 295 kcal

The hamburger is an American icon that has conquered every continent — a simple sandwich of ground beef, bun, and toppings that generates $100 billion in US restaurant sales annually. At 295 kcal per 100 g, it delivers 17 g of protein, 14 g of fat, 24 g of carbohydrates, and 1.3 g of fiber. The modern hamburger likely emerged at American fairs and lunch counters in the late 1800s, though multiple cities claim credit. What is beyond dispute is its efficiency: a complete meal with protein, fat, carbs, and an impressive array of micronutrients in every handheld bite. With 43 g of water, the patty stays juicy while the bun provides structural integrity — engineering disguised as fast food.

What's Inside

Zinc (3.8 mg, 35% DV) is the burger's standout mineral — essential for immune function, wound healing, and over 300 enzyme reactions. Selenium (18 mcg, 33% DV) activates glutathione peroxidase, a critical antioxidant enzyme. Iron (2.8 mg, 16% DV) is the highly bioavailable heme form from beef, absorbed 2-3 times more efficiently than plant iron. Niacin (4.5 mg, 28% DV) drives energy metabolism and DNA repair. Vitamin B12 (1.5 mcg, 63% DV) supports nerve myelination and red blood cell production — found almost exclusively in animal foods. Phosphorus (145 mg, 21% DV) builds bones and powers cellular energy. Potassium (230 mg) supports heart rhythm. Sodium (560 mg) is notable — coming from the bun, condiments, and any seasoning on the patty. The beef also provides small but meaningful amounts of B6, riboflavin, and pantothenic acid that contribute to overall metabolic function.

Getting It Right

The perfect burger patty starts with ground beef at 80/20 lean-to-fat ratio — leaner meat dries out under high heat. Handle the meat as little as possible: overmixing compresses the proteins and produces a dense, sausage-like texture instead of a tender, loose patty. Form patties about 2 cm thick and slightly wider than the bun (they shrink during cooking). Press a thumb dimple in the center to prevent the classic burger bulge. Season generously with salt and pepper on the outside only — never mix seasoning into the meat. Cook on a screaming-hot cast iron pan or grill: 3-4 minutes per side for medium, flipping exactly once. Toast the buns cut-side down in the burger fat for 30 seconds. Stack from bottom up: bun, sauce, lettuce, patty, cheese (melted under a dome for 30 seconds), tomato, onion, top bun. Let the assembled burger rest for 60 seconds before the first bite so the juices redistribute.
