Why Protein Is So Important: The Science Behind It
Introduction
There’s no doubt that protein is an essential macronutrient, but why is it so important? What does it do for our bodies? In this article, we’re going to take a closer look at the science behind protein and find out why it’s so important to get enough of it. Protein is involved in a variety of processes in the body, including cell growth and repair, hormone production, immune function, and more. It’s also necessary for the building and maintenance of muscle tissue. Not only that, but protein is also essential for the recovery process after exercise. So, as you can see, protein is pretty important! Keep reading to learn more about why protein is so important and how you can make sure you’re getting enough of it.
What is protein and why is it important?
Protein is a macronutrient that the body needs for normal function and growth. It’s made up of amino acids, which are linked together in chains. Different foods contain different types of proteins, and the body needs to get all the amino acids it needs from food or supplements. Without sufficient amounts of protein, the body would not be able to build new tissues, repair damaged tissues, create hormones, and many other important functions. It’s also an important source of energy, providing 4 calories per gram.
The role of protein in the body
Protein plays a major role in many biological processes and is necessary for the body’s growth and development. For example, it helps build and repair muscles, bones, and organs, it plays a role in enzyme and hormonal production, it helps form connective tissue, and it helps transport nutrients and oxygen throughout the body. Protein is also involved in the metabolism and synthesis of many vitamins and minerals, including iron, magnesium, and B vitamins. Not only that, but protein is also necessary for the immune system to function properly. It’s also an important source of energy, providing 4 calories per gram.
The different types of protein
There are two types of protein: complete proteins and incomplete proteins. Complete proteins contain all of the essential amino acids the body needs, while incomplete proteins don’t. Animal-based foods like eggs, dairy, meat, and fish are all complete proteins, while plant-based foods are usually incomplete proteins. That said, it’s still possible to get all the essential amino acids from plant-based foods by eating a variety of foods throughout the day. This could include things like beans, nuts, seeds, and grains.
The recommended intake of protein
The recommended daily intake of protein for adults is 0.8-1.2 grams per kilogram of body weight. While some people may need more than this, it’s important to check with your healthcare provider to determine your specific needs. It’s also important to note that individuals who are pregnant or breastfeeding, or those who are very active, may require more protein than the average person.
The benefits of protein
Eating a diet that’s high in protein has many benefits. Not only can it help you feel full and satiated for longer after meals, but it can also help support muscle growth and maintenance, weight loss, and recovery after exercise. Studies have also shown that higher-protein diets can help with controlling blood sugar levels and reducing inflammation in the body. Additionally, protein has been shown to boost the immune system and improve mood.
The best sources of protein
The best sources of protein include animal-based food such as eggs, dairy, meat, and fish. Plant-based sources of protein such as beans, nuts, seeds, and grains are also good sources. It’s also important to note that certain foods such as quinoa, soy, and hemp are complete proteins and contain all the essential amino acids the body needs. If you are not able to get all of your protein through whole foods, then a protein supplement is the next best option. You don't want to go without protein for an extended period of time, usually 3-4 hours between meals.
The bottom line
Protein is an essential macronutrient that’s necessary for normal growth and development and a variety of other important processes in the body. Eating enough protein is important for maintaining a healthy weight, reducing inflammation, boosting the immune system, and more. Luckily, there are plenty of food sources to help you meet your daily protein needs.
