Chicken or lamb: which is healthier?
Full comparison · Protein · Calories · Healthier · Zinc
Neither food is healthier in every way. Per 3.5 oz (100 g), here is where chicken and lamb differ against FDA Daily Values, so you can choose for what you need more or less of.
Chicken
- No nutrient where it is clearly ahead.
Lamb
- More of: vitamin b12 (109% vs 14% DV), iron (10% vs 6% DV), potassium (7% vs 5% DV).
- Also more of what the FDA treats as nutrients to limit: saturated fat (41% vs 5% DV).
Beyond the nutrient table
Health effects depend on more than composition: how much you eat, what it replaces, and the studies on each food. These pages grade that evidence:
What the numbers don't tell you
The table compares roasted chicken breast with broiled ground lamb. 4 oz (113 g) of chicken gives about 35 g of protein, 4 g of fat and 186 calories. Lamb gives about 28 g of protein, 22 g of fat (9 g saturated) and 320 calories. Lamb has more iron, 2.0 mg against 1.2 mg.
In 36 women eating lamb or chicken three times a week for 5 weeks each, blood lipids did not differ between the diets. Long-term data are observational. A 2025 pooling tied lamb to an 11% higher colorectal cancer risk, a weak link from 6 studies, and WHO places red meat, lamb included, in Group 2A, probably carcinogenic. Pooled cohorts gave a stroke relative risk of 1.11 for red meat and 0.87 for white meat.
Skip washing raw chicken, since rinsing spreads bacteria. Cook poultry to 165 °F (74 °C). FSIS gives 145 °F (63 °C) with a 3-minute rest for lamb steaks, chops and roasts, and 160 °F (71 °C) for meatballs, burgers and uncooked sausages made with ground lamb. Alpha-gal allergy can cause reactions one to several hours after lamb and other mammalian meat. CDC names undercooked lamb as one route of Toxoplasma, which matters most during or just before pregnancy.
For lean protein, choose chicken breast. For lamb, cook to the temperature for its cut.
Evidence behind this note
- Level B Swapping lean lamb for lean chicken three times a week for five weeks left total cholesterol, LDL and triglycerides unchanged in 36 women. Br J Nutr, 2012
- Level C Lamb was tied to an 11% higher colorectal cancer risk (RR 1.11, 95% CI 1.02 to 1.21) in a 2025 meta-analysis, and only 6 of its 27 studies measured lamb at all. J Gastrointest Cancer, 2025
- Level E WHO places red meat, which by its own definition includes lamb, in IARC Group 2A, probably carcinogenic to humans. WHO, Cancer: Carcinogenicity of the consumption of red meat and processed meat
- Level B White meat is the one meat category that pointed the other way for stroke: total, red and processed meat all went with higher risk, poultry with lower. Kim et al., Journal of the American Heart Association, 2017
- Level E The agency responsible for US poultry safety tells people not to wash raw chicken, because rinsing spreads the bacteria instead of removing them. Chicken from Farm to Table, USDA Food Safety and Inspection Service
- Level E For the chicken and pork in adobo, USDA FSIS advises 165 °F (74 °C) for poultry and 145 °F (63 °C) plus a three-minute rest for raw pork cuts, checked with a food thermometer. USDA FSIS, Doneness Versus Safety
- Level E USDA FSIS advises cooking uncooked sausages made with ground pork, beef, lamb or veal to 160 °F (71 °C), and those made with ground turkey or chicken to 165 °F (74 °C). USDA FSIS, Sausages and Food Safety
- Level E USDA FSIS says to cook meat loaf, meatballs and hamburgers to a safe minimum internal temperature of 160 °F (71 °C) to be sure all bacteria are destroyed. USDA FSIS, Ground Beef and Food Safety
- Level E A US gastroenterology practice update warns that the same allergy can cause anaphylaxis one to several hours after mammalian meat, which is why it is missed. Clin Gastroenterol Hepatol, 2023
- Level E CDC names eating contaminated undercooked meat, with lamb as one of its examples, as a way Toxoplasma spreads. A woman newly infected during or just before pregnancy can pass the parasite to her unborn child, who can have severe health issues even if she has no symptoms.
