Meat types and cuts, quality, storage, food safety, nutrition and the cooking science behind better results.
Chicken can remain pink even after reaching a safe internal temperature. USDA says color is not a reliable doneness test: poultry should reach at least 165 °F (73.9 °C) in the thickest appropriate area, measured away from bone.
USDA advises against washing raw poultry. Running water can splash bacteria from chicken onto the sink, faucet, counters, utensils or ready-to-eat food. Safe handling and cooking to at least 165 °F in the thickest part are more effective than rinsing.
Raw chicken is naturally water-rich: USDA references put white meat with skin at about 69% water before cooking and 61% after cooking. Liquid in the pan is therefore normal. It becomes more noticeable when the pan is crowded, the surface is wet, the meat was frozen or the product retained water during processing.
Meat shrinks mainly because heat causes proteins to contract and release water while some fat melts out. USDA notes that a beef roast can lose about one-third of its original size and weight when cooked at high heat or for too long. Actual yield varies substantially by cut and cooking method.
Resting meat has two clear effects: internal temperature can keep rising from carryover heat, and less liquid tends to spill out during slicing. But the classic explanation that juices simply “reabsorb” is oversimplified. A 2025 beef-roast study found less slicing loss after 8–13 minutes of rest, yet similar total moisture loss and palatability compared with immediate slicing.
Ground beef that is red on the outside and gray or brown inside can be normal. Oxygen turns surface myoglobin into bright-red oxymyoglobin, while the interior receives less oxygen and can remain purplish or gray-brown. If the entire package is brown and there is also a bad odor or sticky texture, spoilage becomes more concerning.
A brief odor when opening vacuum- or low-oxygen-packed chicken does not automatically mean it is spoiled. Research describes confinement odors, sometimes sour, sulfurous or metallic, that can diminish after opening. A strong odor that persists, especially with slime or questionable storage, is a reason to discard the chicken.
Meat color changes with the chemical state of myoglobin. Without oxygen it can look purplish; with oxygen, bright red; with further oxidation, brown. USDA says these color changes alone do not mean spoilage. Persistent bad odor and a sticky or slimy texture are more concerning.
The most common reason chicken turns dry is overcooking. Lean breast meat loses moisture quickly when it keeps heating after reaching a safe temperature. Evening out thickness, using a food thermometer and stopping once the thickest part reaches 165°F (74°C) reduces unnecessary cooking.
If organ meats are included, liver wins by a wide margin. NIH lists about 5 mg iron in 3 oz (85 g) cooked beef liver, versus ~2 mg in 85 g lean beef round and about 1 mg in similar servings of chicken or turkey. Much of meat iron is also highly bioavailable heme iron.
The lowest-calorie meats are usually very lean cuts. Per 100 g cooked, skinless turkey breast can be around 135 kcal, lean pork tenderloin ~141 kcal, very lean eye of round beef ~157 kcal and roasted skinless chicken breast ~165 kcal. Fat content changes the ranking more than the animal name itself.
A 90/10 label describes the raw mixture: roughly 90% lean tissue and 10% fat by weight. It does not mean 100 g cooked meat will contain exactly 10 g fat, because cooking changes both water and fat content.
