Beef
A complete protein with highly bioavailable iron, zinc, and B12 — but classified as red meat, with higher-quality cuts and cooking methods making a real difference.
Also known as: cow, steak, ground beef, mince

Beef is a dense source of complete protein (all essential amino acids), heme iron (the form most easily absorbed), zinc, B12, and creatine. For people recovering from anemia or building muscle, a few servings a week move biomarkers measurably more than plant sources of the same nutrients.
Red meat and disease risk
The WHO's IARC classifies unprocessed red meat as Group 2A — "probably carcinogenic" — based mainly on colorectal cancer evidence. The signal is smaller than for processed meat (bacon, sausage) and the absolute risk per serving is modest, but it's dose-dependent. Major guidelines (AHA, AICR) suggest keeping unprocessed red meat to around 12-18 oz per week.
How it's cooked matters
High-temperature cooking (charring, grilling over flame, well-done) forms heterocyclic amines and polycyclic aromatic hydrocarbons, both implicated in cancer risk. Slow, lower-temperature methods (braising, sous vide, gentle searing) produce far less. Marinades with herbs and acid (rosemary, lemon, vinegar) measurably reduce HCA formation when grilling.
Grass-fed beef has a slightly better omega-3 to omega-6 ratio and more conjugated linoleic acid than grain-finished, but the differences are small in the context of an overall diet. The bigger lever is cooking method and portion size.
