How Do You Get More Protein In Your Diet

What is a Protein? (from PDB-101)

Of course, people consume foodnot protein per se. So how can you get more protein into the diet? Heres one example:

  • Breakfast: 3 scrambled eggs with a mixture of vegetables: 22 grams protein
  • Lunch: Lentil soup with whole-grain bread : 26 grams protein
  • Dinner: 4 ounces of salmon with brown rice and vegetables: 31 grams protein
  • Nighttime snack: 1 cup yogurt with 2 scoops of protein powder topped with berries: 34 grams protein
  • Total: 113 grams protein and 1,654 calories

Even though protein is found in many whole foods, one of the easiest ways to get a protein boost is to use a protein supplement. Our top recommended high-quality, high-protein supplement protein is BioTrust Low Carb. BioTrust Low Carb contains 24 grams of pasture-raised, grass-fed protein per serving. Not only that, but its soy-free, gluten-free, non-GMO, and made with natural ingredients. Plus, it tastes delicious!

Whether you choose to get your protein from lean meats, eggs, plant-based sources, or a protein supplement, the key is to ensure youre providing your body with the protein building blocks it needs for optimal functioning.

What Do Amino Acids Do Their Role In The Human Body

Weve all heard of amino acids, and most of us have probably even heard the term essential amino acids before. But how many of us have ever stopped to ask ourselves, what do amino acids do?

The term amino acids refers to a class of simple organic compounds whose members contain at least one amino group and one carboxyl group . The word amino is a direct reference to the nitrogen atom contained in the molecule. As such, the presence of nitrogen can be considered the defining characteristic of amino acids.

You may recall learning about the building blocks of protein in your high school biology class. But thats actually a very accurate description of the role amino acids play in the body. Without them, protein would not be created and we would not be here discussing this topic at all.

But how exactly is this feat of protein synthesis accomplished?

The 6 Functions Of Proteins In The Body

In this article, weve featured the 6 functions of protein in the body. Continue reading to learn more.

Folks are always talking about how important it is to eat a well-balanced diet that includes an assortment of carbs, fats, sugars, and proteins. Weve all heard about meat being a great source of protein, but what exactly does that mean? And moreover, what do these proteins do for our body?

There are six functions of proteins in the body including repair and maintenance, muscle contraction, hormone production, enzyme reactions, molecule transportation, and antibody formation. Each function is important in its own way, and a balanced diet of proteins will help to maintain each of these vital operations.

The word protein can be misleading since it is seemingly used so broadly. Were going to take you on a closer look on what exactly a protein is and the different ways these proteins help to keep us operating steadily and healthily through life.

What Happens When You Start Eating More Protein

Beyond being thanked by your body for the fuel, Kimberly Marsh, MS, RD, says that your body will use protein to complete many necessary functions. “If it needs protein for building muscle or other parts of the body, it will use it for that,” she tells Lively. “If it needs it for hormones or enzymes, it will use it for that.”

You may also see changes in your appetite. If you go from not getting enough protein to getting an adequate amount, this means you may go longer between that egg scramble you had for breakfast and being hungry for another meal.

“Protein is a very satisfying macronutrient leading to lower calories consumed and less snacking between mealtimes,” explains Richards. This will aid in any weight loss goals you have, as well as assist in glucose control.

A lesser-known fact about amino acids is that they may provide mood-boosting benefits. According to Heather Hanks, MS, a nutritionist with Instapot Life, this surprising form of zen comes from amino acids connection to neurotransmitters in the brain. Amino acids are required for the synthesis of neurotransmitters that influence mood and brain health, such as GABA. You may have seen this word on supplements that promote calmness** . Hanks says that “If you want to help stabilize your cognitive abilities and make it easier to concentrate,** protein can help,” Hanks says.

oing a little research into how a supplement works can help you determine whether you can benefit from adding it to your daily routine. Read on to find out what protein powder does so you can decide for yourself whether or not you need it.

Why use protein powder?

Not only is protein necessary for the maintenance of our bones, muscles, and skin, but the body also needs it to make hormones, enzymes and other vital chemicals. Naturally, making sure you get enough protein is essential for good health and fitness. If you feel weak when lifting weights, unusually tired, or your post-workout recovery is slow, you may not be getting enough protein for your needs.

The general recommendation for people aged 19 years and over is 46g of protein for women and 56g of protein for men. However, this recommendation is very general, and many people will need to exceed this recommendation to meet their nutritional needs.

How much protein your body requires for tissue growth and repair is determined by many factors, including sex, age, body composition, health, and activity level. For example, research suggests people with an intense training program may benefit from doubling the recommended protein intake. Protein should comprise anything from around 15% to 30% of your daily caloric intake, depending on your individual needs.

Protein Is A Nutrient

Protein is a nutrient that the body needs to grow and maintain itself. Next to water, protein is the most plentiful substance in our bodies. Just about everyone knows that muscles are made of protein. Actually, every single cell in the body has some protein. In addition, other important parts of the body like hair, skin, eyes, and body organs are all made from protein.

Many substances that control body functions, such as enzymes and hormones, also are made from protein. Other important functions of protein include forming blood cells and making antibodies to protect us from illness and infections.

Building Blocks For Every Cell

Protein is considered one of the bodys most essential nutrients because its a valuable unit to every cell in the body.

Odds are you can recall from your high school biology class that proteins are made up of amino acids. These amino acids are often coined building blocks because together they are able to form or build the various protein structures needed for almost every one of lifes processes. When consuming dietary protein, you are supplying your body with these highly essential organic compounds.

Besides being an integral part of the body, dietary protein has been shown to produce powerful benefits. Protein is a multi-functional tool that can help people of all ages, shapes, and sizes enjoy better health and bodies.

So, what does protein do for your body? Here is a quick list.

Key Benefits Of Protein For Health And Athletic Performance

Functions Of Protein In The Body – How The Body Uses Proteins

Dana RyanPh.D., MA, MBA Director, Sports Performance, Nutrition and Education

Protein is essential for every single person, every single day. Protein becomes even more important the more active we are, and while most people know that it is important, often we dont understand why its important.

Proteins are made up of amino acids, and these proteins and amino acids are the main building blocks of our muscles, bones, skin, tissues, and organs. When we consume protein, our body breaks it down into individual amino acids during digestion and then uses these amino acids to create new proteins throughout the body. It is essential to consume an adequate amount of protein otherwise, the body will have to break down muscle to obtain the amino acids that it needs to function.

Now that we understand the role of protein in the body, there are 3 main benefits that we often focus on with protein.

How Much Protein Do You Need

Not getting enough protein in your diet can lead to health issues. For example, tissue can break down and lead to muscle loss.

But more isnât necessarily better. While it can help build muscle, if you take in too much your body may store the excess as fat.

The Dietary Guidelines for Americans, put together by the U.S. Department of Agriculture and the U.S. Department of Health and Human Services, recommend the following daily amounts of protein for different age groups:

  • Children under 4: 13 grams
  • Children ages 4 to 8: 19 grams
  • Children ages 9 to 13: 34 grams
  • Women and girls ages 14 and over: 46 grams
  • Boys ages 14 to 18: 52 grams
  • Men ages 19 and over: 56 grams

Simply put, most everyone should get 10% to 35% of their calories each day in the form of protein. You need more calories for activities like biking, lifting weights, or running, but the percentage of protein remains in the same range.

After age 40, you can start to lose muscle mass, a condition known as sarcopenia, and you may need more protein.

If youâre overweight, youâll need to lower your calorie intake. A dietitian can help you figure out how much protein you should have.

What Does 1530 Grams Of Protein In Whole Foods Looks Like

Eating a banana, Greek yogurt and a hard-boiled egg will get you 19 grams of protein on average. A 3-ounce chicken breast with a half-cup rice and a half-cup of vegetables amounts to 25 grams protein. An egg and bean burrito with a glass of milk is about 28 grams of protein.

As you can see, itâs easy to get the recommended 1530 grams per meal. Most people even athletes can reach their protein needs by including a serving of dairy at each meal and a piece of meat the size of a deck of cards at lunch and supper.

Protein should accompany fruits, vegetables and whole grains. Protein should not be the entire meal. If you feel like you might have increased protein needs, consider adding more beans, lentils, soy or seafood rather than processed supplements.

Why We Even Need Protein

That building block nickname is no exaggeration. The stuff is an integral component of every cell in your body, including, yes, your muscles.

If we dont get enough protein, our bodies actually wont be able to rebuild properly and well start to lose muscle mass, Colleen Tewksbury, Ph.D., M.P.H., R.D., senior research investigator and bariatric program manager at Penn Medicine and president of the Pennsylvania Academy of Nutrition and Dietetics, tells SELF.

Protein helps repair the microtears that occur in your muscle fibers when theyre strained during exercise, the American College of Exercise explains. That process of damage and repair is what maintains and grows your muscle mass.

But protein is not just important for people who work out: In addition to muscle growth and repair, protein is essential to the growth and repair of virtually all cells and body tissuesfrom your skin, hair, and nails to your bones, organs, and bodily fluids, according to the FDA. Thats why its especially important to get enough of it during developmental periods like childhood and adolescence.

Protein also plays a role in crucial bodily functions like blood clotting, immune system response, vision, fluid balance, and the production of various enzymes and hormones, per the FDA. And because it contains calories, it can provide the body energy for storage or use.

Helps Build Muscle Mass

What is Protein anyway?

It helps build and maintain muscle mass and strength. When your metabolism works efficiently, more muscles are formed. At age 40, you may experience loss of muscle mass and strength which requires eating protein more and reducing calorie intake.

People who exercise vigorously to gain skeletal muscle mass do not need extra protein. High protein diets do not cause muscle mass. The stimulation of muscle tissue causes muscle mass through exercise, which leads to muscle growth, not extra dietary protein.

Staying physically active is essential, including working out in gyms or engaging in resistance exercise.

To help prevent losing muscle mass, known as sarcopenia, you need more protein to gain muscle. Some who have a hard time taking in more protein resort to dietary protein thats fine as long as its not too much. Very high protein diets are dangerous.


A study published in the American Journal of Clinical Nutrition showed that a large single dose of 25 g of protein after exercise could increase muscle protein synthesis.

This finding could explain why protein shakes are often associated with those who work out, body builders, and gym rats.

Protein Deficiency Can Lead To Malnutrition

Protein deficiency can lead to malnutrition, such as kwashiorkor and marasmus. Both of these conditions are life-threatening.

This protein deficiency happens if a person has a health condition such as an eating disorder like anorexia nervosa.

An energy deficit due to the deficiencies of many micronutrients is called Protein-energy undernutrition . This condition can be sudden caused by total starvation or gradual.

Potential Benefits For Bones

In addition to improving some aspects of skin health and appearance, collagen supplements may offer a few other benefits.

One study looked at the effects of taking collagen supplements in 102 women in postmenopause who had reduced bone mineral density .

Those who took 5 grams of collagen peptides per day for 1 year had significant increases in BMD in their spine and femur compared with participants who took a placebo .

A follow-up study in 31 of these women found that taking 5 grams of collagen daily for a total of 4 years was associated with a progressive increase in BMD.

The researchers found that participants BMD increased by 5.798.16% in the spine and by 1.234.21% in the femur during the follow-up period .

These findings suggest that taking collagen supplements long-term may help increase bone mineral density in people in postmenopause, who are at a greater risk of developing osteopenia and osteoporosis.

Whats more, one review article concluded that taking oral collagen supplements reduced participants symptoms related to osteoarthritis, including stiffness .

Collagen supplements may provide other health benefits as well, such as improving body composition in certain populations when combined with resistance training .

Its important to note that studies observed these beneficial effects of taking collagen mainly in older women with low bone mineral density.

Why Does Your Body Need So Much Dairy Food

How Does Protein Build Muscle?

There are lots of essential nutrients in dairy. Each time you eat or drink dairy, you are giving your body calcium, iodine, vitamin A, vitamin D, riboflavin, vitamin B12 and zinc.

Calcium and vitamin D help your body build strong dense bones as you grow, and they keep your bones strong and healthy as you get older. Most adults need 1,000 milligrams of calcium every day. This increases to 1,300 milligrams for women aged over 50 and men aged over 70.

Not having enough calcium in your diet may increase your risk of osteoporosis. Osteoporosis is a disease of the bones, where they become brittle and weak and can break easily.
