We developed the Eating for Success series to give you the foundational information you need to build a healthy diet that supports your fitness goals. A healthy diet for athletic performance emphasizes lean proteins, vegetables and fruits, with moderate amounts of low-fat dairy and whole grains. Right now, our focus is lean protein, one of the primary building blocks of any muscle gain or weight loss program. Today, it’s chicken!
Why chicken is a lean protein staple
Chicken is one of the world’s most popular sources of lean protein. Plus, it’s packed with nutrients and highly versatile: you can roast, bake, broil or grill it into a delicious, nutritious meal. The breast is the leanest part, but most chicken is fairly low in fat once you remove the skin. However, eating the skin roughly doubles the fat and saturated fat, so consider removing it before eating.
Chicken nutrition facts
According to USDA data, 4 ounces of roasted, skinless chicken breast provides roughly 185 calories, 35 grams of protein and about 4 grams of fat, with no carbohydrates. That’s why chicken nutrition stands out: it’s also a rich source of several vitamins and minerals. You can compare cuts in the USDA’s FoodData Central database.
5 chicken nutrition benefits for your health
1. High-quality protein for muscle
Chicken provides all the essential amino acids your muscles need to repair and grow after training. As a result, it’s a go-to protein for anyone lifting weights or trying to preserve muscle while losing fat.
2. Niacin (vitamin B3) for energy
In addition, chicken is one of the best food sources of niacin, which helps your body convert food into energy and supports healthy skin and nerves.
3. Vitamin B6 for brain and blood
Also, vitamin B6 supports normal brain and nerve function, helps form red blood cells and plays a role in breaking down protein.
4. Selenium and phosphorus
Selenium supports the immune system and thyroid and is part of antioxidant enzymes. Meanwhile, phosphorus works with calcium to build strong bones and helps your body produce energy.
5. Choline for the brain and liver
Chicken also provides choline, a nutrient that supports brain function, memory and liver health. In addition, chicken contains tryptophan, an amino acid your body uses to make serotonin.
Choosing chicken for the best chicken nutrition
Similar to eggs, we suggest choosing organic or free-range chicken raised without antibiotics when your budget allows. That said, U.S. law doesn’t allow hormones to be used in raising poultry, so a “no added hormones” label on chicken doesn’t set it apart. Conventional chicken is still a healthy, affordable protein. Finally, always cook chicken to 165°F, according to USDA safe temperature guidelines, and avoid rinsing raw chicken, which can spread bacteria around your sink.
Healthy recipes to enjoy chicken nutrition
Spice-rubbed roast chicken
Ingredients: 1 (4 to 5 lb) roasting chicken; 2 1/2 Tbsp salt-free Cajun seasoning blend; 2 1/2 tsp olive oil; 2 limes, quartered; 1 head garlic, halved horizontally; olive oil spray.
- First, heat the oven to 400°F. Pat the chicken dry. Coat a roasting pan with olive oil spray and place the chicken in the center.
- Next, mix the seasoning and olive oil into a paste and rub it all over the chicken. Squeeze one lime wedge over the top and stuff the rest inside the cavity. Place the garlic halves in the corners of the pan and coat with olive oil spray.
- Roast in the middle of the oven until an instant-read thermometer in the thickest part of the thigh reads 165°F, about 1 hour. Let it rest 10 minutes before carving, and serve with the roasted garlic to spread on the chicken.
Chicken breasts baked with lemon and garlic
Ingredients: 2 Tbsp olive oil; 2 large cloves garlic, minced; grated peel and juice of 1 lemon; 1/2 tsp coarse salt; 1/2 tsp ground pepper; 4 large boneless, skinless chicken breasts; 1/4 cup chicken broth.
- Heat the oven to 400°F. In a small skillet over medium heat, warm the oil, add the garlic and sauté 30 seconds. Stir in the lemon juice, salt and pepper, bring to a boil and set aside.
- Next, arrange the chicken in a single layer in a baking dish coated with olive oil spray. Pour the lemon-garlic mixture over the chicken, sprinkle with lemon peel, cover with foil and bake 15 minutes.
- Then remove the foil and bake another 10 to 15 minutes, until cooked through to 165°F. Meanwhile, pour the pan liquid into the skillet, add the broth and boil until reduced by half. Pour the sauce over the chicken and serve.

Frequently Asked Questions

How much protein is in a chicken breast?
About 35 grams of protein are in 4 ounces of roasted, skinless chicken breast. A typical large chicken breast can weigh 6 to 8 ounces cooked, so it may provide 50 grams of protein or more.
Is chicken breast or thigh healthier?
Breast is leaner and higher in protein per calorie, which makes it ideal for weight loss. Thighs have more fat and a bit more iron and zinc, and they stay juicier. Both are healthy when you remove the skin.
Is it healthy to eat chicken every day?
Yes, for most people, skinless chicken can be part of a healthy diet every day. Rotate in other proteins like fish, beans, eggs and turkey for a wider range of nutrients, and prepare it without heavy breading or frying.
Should you wash raw chicken?
No. Food safety experts advise against rinsing raw chicken because it can splash bacteria around your sink and kitchen. Cooking chicken to an internal temperature of 165°F kills harmful bacteria.
