Animal Protein vs. Plant Protein: Which Is Better for Building Muscle?

Animal Protein vs. Plant Protein: Which Is Better for Building Muscle?

There’s no question: protein is essential for muscle growth. But with so many types of protein to choose from, which is best for building muscle? 

Animal protein is recognized for its complete amino acid profile and high-quality protein content. On the other hand, plant protein has become a popular choice with the rise of plant-based diets. The nutritional composition and amino acid profiles of these two types of proteins differ significantly, which can impact their effectiveness in muscle growth.

With “bulking season” just around the corner, it is essential to understand the distinct attributes of animal and plant-based proteins and their implications on muscle growth. To help you determine which protein is best for building muscle, we’ll explore their amino acid profiles, the nutrients, and the benefits of animal and plant protein.

Does the Source Really Matter for Muscle Growth?

When it comes to building muscle, protein is a crucial factor. But does the source of your protein affect muscle growth? 

Animal proteins are often the most popular protein sources for muscle growth because they contain all nine essential amino acids required for muscle protein synthesis. While some plant proteins contain all essential amino acids, it is generally recommended for those following a plant-based diet to consume a variety of protein sources to ensure a complete amino acid profile.

A key factor to consider when determining what protein is best for muscle growth is the protein source's digestibility and amino acid composition. Animal protein has a higher digestibility rate, allowing for better absorption of the amino acids. Plant protein tends to have a lower digestibility rate, which may lead to slightly decreased muscle protein synthesis compared to animal protein sources.

Both animal and plant proteins can contribute to muscle growth. Though animal protein is usually considered to be superior for building lean muscle mass, when consumed in sufficient quantities with a proper balance of amino acids, plant-based protein can be an effective source for stimulating muscle protein synthesis. 

What is Animal Protein?

Animal protein refers to protein sources derived from animal products, including meat, eggs, fish, and other edible parts of animals. Often considered the highest-quality protein source, animal proteins are called complete proteins because they contain all nine essential amino acids the human body requires. These amino acids are necessary for various bodily functions, such as muscle growth and tissue repair. The most common animal protein sources include poultry, beef, pork, fish, and dairy.

In the context of building muscle and developing lean mass, animal proteins are particularly beneficial due to their high bioavailability and ease of absorption by the body. This advantage is attributed to the fact that animal proteins have protein profiles that closely resemble those of human proteins. 

Health Benefits of Animal-Based Proteins

In addition to supporting lean muscle mass and maintenance more effectively than their plant-based counterparts, animal protein has several health benefits. What sets animal proteins apart from plant proteins is their completeness and the nutrient richness of the animal products. Animal proteins typically offer a higher concentration of nutrients, such as B vitamins, iron, and zinc, compared to plant-based protein sources. 

Animal protein also has a high biological value (BV). This determines how efficiently our bodies can utilize the protein we consume. Animal proteins have a higher BV than plant proteins, meaning that our bodies can more easily absorb and use the nutrients found in animal-based sources.

Another advantage of animal proteins is their influence on body composition and weight management. Diets rich in high-quality proteins, such as those derived from animals, can improve body composition and weight loss when combined with regular exercise. Not to mention animal protein also can lower the risk of type 2 diabetes, heart disease, and colorectal, stomach, pancreatic, and prostate cancer.

Considerations for Eating Animal-Based Protein

To support muscle growth and overall health, it is essential to consider the types of animal protein you're consuming (like whey protein powders, for example) and any risk factors associated with this choice. A primary concern when consuming animal proteins is the quality of the source. For example, grass-fed and wild-caught options are generally healthier than their conventionally raised counterparts due to their higher levels of beneficial nutrients such as omega-3 fatty acids. 

Another critical consideration is the saturated fat content in certain animal proteins, particularly red meat. Consuming high amounts of saturated fat can lead to increased cholesterol levels, which, in turn, can elevate the risk of developing heart disease. That being said, it is essential to consult a dietitian for guidance before making any dietary changes.

What is Plant Protein? 

While plant proteins are typically incomplete – lacking one or more essential amino acids – they can be complemented with other plant-based protein sources to form a complete protein profile. Plant proteins are commonly found in whole grains, legumes, nuts, seeds, and vegetables like spinach and broccoli.

To ensure optimal muscle growth with plant protein, consider incorporating a variety of plant protein sources, such as:

  • Beans and legumes (lentils, chickpeas, etc.)
  • Nuts and seeds (almonds, chia seeds, etc.)
  • Whole grains (quinoa, bulgur, etc.)
  • Plant-based protein powders (pea protein, hemp protein, etc.)

Combining different plant protein sources, such as beans and rice or hummus and whole-grain bread, ensures you get a complete range of amino acids, making plant protein a valuable addition to your diet.

Health Benefits of Plant-Based Proteins

Plant-based proteins offer a plethora of health benefits that extend beyond just meeting your daily protein needs. One of the most significant advantages is their role in promoting overall health and reducing the risk of chronic diseases. Studies have shown that diets rich in plant-based proteins can help protect against heart disease by lowering cholesterol levels, reducing blood pressure, and improving cardiovascular health. Additionally, these proteins have been associated with a lower risk of certain cancers, stroke, and type 2 diabetes.

Plant-based proteins are also known for their positive impact on other aspects of well-being. They can aid in weight management by increasing feelings of fullness and satiety, which can help prevent overeating. Incorporating plant proteins into your diet may also lead to better sleep quality, enhanced immune function, and improved digestive health. These proteins are often accompanied by essential nutrients, such as fiber, vitamins, and minerals, contributing to their overall health benefits.

Considerations for Eating Plant-Based Protein

To maximize the benefits of plant-based proteins, it's essential to consume a variety of plant-based foods that are high in protein. Some excellent sources include tofu, tempeh, edamame, chickpeas, almonds, and hemp seeds. Incorporating these foods into your meals can be a delicious and nutritious experience. For example, you can blend silken tofu into smoothies for a creamy texture, add roasted chickpeas to salads for extra crunch, or sprinkle almond slices on oatmeal for a satisfying crunch.

One convenient way to boost your plant-based protein intake is by using plant-based protein powders. These supplements can be mixed into shakes or added to recipes to increase protein content, making it easier to meet your daily requirements. 

Build Muscle With Nutmeg State Nutrition

Choosing between animal and plant-based protein comes down to personal preference and dietary choices. Both types of protein can aid in muscle growth, provided they are consumed in the proper amounts and with sufficient essential amino acids. A well-rounded diet that includes a mix of various protein sources, along with proper training, will ultimately yield the desired muscle growth.

By incorporating various Nutmeg State Nutrition’s animal and plant-based protein sources into your meals, you can enjoy the advantages of plant-based proteins while maintaining optimal nutrition.
