While working out is important for building strong muscles, having a balanced diet is equally essential. No matter how intense your workouts are, without proper nutrition, you won't get the results you are hoping to achieve. Most importantly, your diet should include protein, which is made up of amino acids that are part of building and maintaining your muscles and bones. To help you plan your meals and work toward growing your muscles, we discuss how food helps build muscles and which foods specifically can optimize your workouts. Of course, before making any changes to your diet, you should consult your doctor.How food builds muscle Upgrade your inbox Get cnet insider From talking fridges to iPhones, our experts are here to help make the world a little less complicated. Although protein is essential for muscle building, it's not the only important food component in the process. According to the National Academy of Sports Medicine, a good muscle-building diet must also include plenty of carbohydrates, vitamins and minerals. A balanced diet that features all these will provide the necessary ingredients to help your muscles repair and rebuild after a workout.Overall, the NASM recommends that most people consume at least 0.7 to 0.8 grams of protein and 1.8 to 3.2 grams of carbohydrates per pound of body weight each day. Total calorie intake also plays a role in muscle building, as it's difficult to build muscle if you're burning more calories than you consume.Diet alone isn't enough to stimulate muscle growth. Exercise primarily resistance training, such as lifting weights is necessary to start the process. When you tear the fibers in your muscles, that stimulates cellular growth and repair. That's when your body can use the food you've eaten to rebuild and strengthen muscle tissue. Other factors also influence how effective and efficient this process is, from when you eat your food and how much rest you give your muscles between workouts to your hormonal and genetic makeup. Tanja Ivanova/Getty Images8 foods to build muscle and optimize your gainsAlthough there are many factors at play in building muscle, there's no doubt diet plays a key role. Here are eight muscle-building foods you can eat to optimize your workouts and increase your muscle mass.1. EggsEggs have long been considered a power food, and for good reason. They're incredibly rich in nutrients from fat and protein and include a potent mix of vitamins such as B12, B6 and thiamin. Their nutrient-dense profile makes them especially powerful, but most important is that they contain a hefty dose of leucine. This amino acid is known for its muscle-building prowess.2. FishIf you already have enough fat in your diet but need to boost your protein intake, look no further than fish. It's one of the best lean sources of protein you can eat, and it's full of other vitamins and minerals. A bonus? Fish is packed with omega-3 fatty acids. Although they're known for their many other health benefits, omega-3s may also improve muscle performance and help prevent the loss of muscle mass. Salmon and tuna are particularly great muscle-building food choices.3. NutsWhen eaten in moderation, nuts are an excellent choice for building muscle. These tasty snacks offer a perfect mix of protein, fats and fiber, making them one of the most balanced ways to supplement your workouts. You have to be careful, as many nuts (including peanuts, which are actually legumes), are high in calories. For the most nutrient-rich options, try almonds or walnuts.4. SoybeansIf you're trying to build muscle on a meatless diet, soybeans should be one of your closest friends. These are some of the most nutrient-dense legumes you can eat, and they pack a potent punch of protein to aid in building muscle. Soy contains all nine essential amino acids, making it one of the best plant-based protein sources available. Lauren Burke/Getty Images5. Greek yogurtDairy is a unique source of protein because it provides a combination of fast-digesting whey protein and slow-digesting casein protein. When consumed together, these two types of protein may enhance and prolong the protein-synthesis process that your muscles go through when rebuilding, helping you build your lean mass. Greek yogurt is a particularly great dairy choice because it contains twice the protein compared to regular yogurt and boasts additional probiotic health benefits you can't find in milk or cheese.6. Cottage cheeseIt doesn't offer the same probiotic benefits as yogurt, but cottage cheese is a great second choice for dairy-based protein. Cottage cheese packs more protein than Greek yogurt while boasting the same slow- and fast-digesting combination. It's a particularly great source of casein, and it provides a significant calorie boost if you need to make sure you're getting enough.7. Olive oilIt may not sound like your typical body-building food, but extra virgin olive oil has become increasingly popular for its muscle benefits in recent years. Widely known as a source of healthy monounsaturated fats, olive oil also helps to reduce inflammation and slow muscle breakdown. Both of these features can aid in any muscle-building regimen.8. QuinoaThey don't call quinoa a superfood for nothing. This dynamic grain (it's a seed but classified as a whole grain) packs a little bit of everything, including a lot of protein, fiber and carbohydrates, plus a hefty dose of vitamins and minerals. It's a perfect food for building muscle and maximizing the benefits of your workouts.
