Chicken gizzards are a nutrient-dense, high-protein food that delivers impressive amounts of iron, zinc, selenium, and vitamin B12 for very few calories. One cup of cooked, chopped gizzards packs 44 grams of protein and under 4 grams of fat, with zero carbohydrates. The main nutritional caveat is their high cholesterol content, which may matter if you’re watching your intake.
Protein and Calorie Profile
Gizzards are one of the leanest animal proteins you can eat. A cup of simmered, chopped gizzard contains roughly 223 calories, 44.1 grams of protein, and just 3.89 grams of total fat. For context, that protein-to-calorie ratio rivals skinless chicken breast, making gizzards a solid choice if you’re trying to build muscle or lose weight without sacrificing satiety.
Because gizzards are essentially a thick, muscular organ (the part of the bird’s digestive tract that grinds food), they contain significant connective tissue and collagen. This gives them their distinctively chewy texture and means they contribute to your intake of the structural proteins your body uses to maintain joints, skin, and gut lining.
Vitamins and Minerals
Where gizzards really stand out is micronutrient density. One cup of cooked gizzards provides:
- Iron: 4.63 mg, covering roughly 25% of the daily need for most adults. This is heme iron, the form your body absorbs most efficiently from animal sources.
- Zinc: 6.41 mg, about 58% of the daily value for men and over 80% for women. Zinc plays a central role in immune function and wound healing.
- Selenium: 59.6 mcg, which covers most of your daily requirement. Selenium is essential for thyroid hormone production and acts as a building block for enzymes that protect your cells from oxidative damage.
- Vitamin B12: 1.51 mcg, roughly 63% of the daily value. B12 is critical for nerve function and red blood cell formation.
The selenium content is particularly notable. Your thyroid gland produces hydrogen peroxide as part of making thyroid hormones, and selenium-dependent enzymes neutralize that peroxide before it damages thyroid cells. Getting enough selenium through foods like gizzards supports this protective cycle and helps maintain healthy thyroid hormone levels.
The Cholesterol Question
This is the biggest nutritional trade-off with gizzards. A single cup of simmered gizzards contains about 536 mg of cholesterol, nearly double the 300 mg daily limit that older dietary guidelines recommended. For comparison, two slices of fat-free roasted chicken breast contain just 15 mg.
Current research has softened the link between dietary cholesterol and blood cholesterol for most people, and the most recent U.S. dietary guidelines removed the strict daily cap. Still, if you have high cholesterol, heart disease, or diabetes, eating gizzards frequently could be worth discussing with your doctor. For most healthy adults, eating gizzards a few times a week as part of a varied diet is unlikely to cause problems, but they’re not a food to eat in large quantities every day.
Purine Content and Gout Risk
If you have gout or elevated uric acid levels, organ meats deserve extra caution. While specific purine data on gizzards is limited, chicken liver contains around 323 mg of purines per 100 grams, which is considered high. Regular chicken breast sits in the moderate range at about 158 mg per 100 grams. Gizzards likely fall somewhere between the two, given their organ meat classification, but they are muscular tissue rather than a filtering organ like the liver. If you’re managing gout, keeping portions modest and infrequent is a reasonable approach.
Heavy Metal Concerns
Because the gizzard’s job is to physically grind everything a chicken eats, it comes into direct contact with whatever the bird ingests. A 2024 study published in Heliyon that analyzed commercial poultry in Nigeria found that gizzards accumulated cadmium and nickel at concentrations well above international safety limits set by the FAO and WHO. Chromium and manganese levels were also elevated. The liver accumulated more of certain other metals, but the gizzard was the only tissue where cadmium and nickel were consistently detected.
This doesn’t mean every gizzard you buy at the grocery store is contaminated. Metal accumulation depends heavily on what the chickens were fed, the quality of their water, and environmental conditions at the farm. Poultry raised under stricter food safety standards in countries with tighter regulations will generally carry lower risk. But this is worth knowing if you eat gizzards very frequently or source them from regions with less oversight of poultry farming practices.
Best Ways to Cook Them
Gizzards are pure muscle, which means dry heat alone (like pan-frying straight from raw) tends to make them tough and rubbery. The key is moist, gentle cooking: simmering, braising, stewing, or pressure cooking breaks down the connective tissue and produces a tender result. Many traditional recipes simmer gizzards for one to two hours before finishing them with a quick fry for crispness.
If you boil or stew gizzards, the cooking liquid absorbs a meaningful share of the water-soluble vitamins and minerals that leach out during cooking. Using that stock as a base for soup, sauce, or gravy lets you recapture those nutrients instead of pouring them down the drain. Deep frying adds significant calories and fat to what is otherwise an exceptionally lean protein, so if your goal is nutritional value, braising or stewing is the better route.
How Gizzards Compare to Other Cuts
Compared to chicken breast, gizzards offer more iron, zinc, selenium, and B12 in a similar calorie range, but with far more cholesterol. Compared to chicken liver, gizzards are lower in vitamin A and folate but also lower in purines and less likely to accumulate certain heavy metals. They sit in a useful middle ground: more nutrient-dense than standard muscle meat, with fewer of the extremes that come with organs like liver or kidney.
For most people, gizzards are a genuinely healthy, affordable protein source that adds variety and micronutrient depth to your diet. Eating them a couple of times a week, prepared with moist heat and minimal added fat, is a straightforward way to get high-quality protein along with minerals that many people fall short on.
