Best Sources Of Protein
Protein comes from plant and animal sources, and you can meet your protein needs with either type of protein. Plant sources are typically not considered complete proteins since they lack all of the essential amino acids. For this reason, eating a wide variety of plant-based proteins that cover all of the amino acids you need is important.
Here’s Exactly Why You Need Protein
Protein is vital to life: Its made from amino acids that are essential for building and maintaining muscles and bones. In addition, recent studies suggest that protein quality, or the total makeup of amino acids within a protein source, may become more important as you age.
But beyond your infrastructure, protein also helps to regulate a host of cellular processes, affecting everything from your immune function to the transportation of oxygen through the bloodstream. Protein can even aid in weight loss: Researchers have found that consuming it stimulates the release of satiety signals in the small intestine, helping you feel full.
In short, protein is a super-nutrient. A do-it-all. A power player in how you use your body and what it looks like.
Protein is important. In fact, its vital for building the body you want. Protein helps , builds and maintains muscle, fortifies your bones, improves brain function, aids your immune system, and can even pick up the kids from soccer practice if youre strapped for time.
We digested the past 25 years of nutrition knowledge, talked to the smartest experts about the latest science, and sorted through a lot of nutrition B.S.all to provide you with the most up-to-date information about protein right now.
How Much Protein Do Women Need Are You Getting Enough
Protein is an essential part of any well-balanced nutrition plan. However, there are vastly different opinions on how much protein women actually need. Too little and you may suffer from weakness, fatigue, or muscle loss too much and you may gain weight, have kidney issues, or suffer from irritability. The appropriate amount of protein for any person depends on activity levels, age, muscle mass, body shape goals, and overall health.
What is protein?
Proteins are composed of amino acids and amino acids are the building blocks of life. Amino acids help build cells, enzymes, antibodies, and muscles. Proteins are important energy sources for humans and approximately one gram of protein provides four calories of energy.
Why do women need protein?
Consuming enough protein may in women. According to one study, women who ate the most protein were 25% less likely to have had a heart attack or have passed away from heart disease than the women who ate the least protein over a 14 year period.
Women suffer from bone loss as they age and protein contributes to adequate bone strength and density. Protein makes up about 50% of the volume of bone and about 33% of its mass. Eating enough high-quality protein contributes to maintenance of sufficient muscle mass and function, which is critical for overall bone health.

How Much Protein Per Meal
Muscle protein synthesis is the process of building new skeletal muscle tissue. When MPS chronically exceeds muscle protein breakdown , resulting in a positive net protein balance, we can expect muscle growth over the long term. Each time you eat represents an opportunity to promote muscle growth through the stimulation of MPS.
Protein-feeding studies using various doses of suggest that 0.24 g/kg/meal will maximize the MPS of the average young adult, whereas 0.40 g/kg/meal will maximize the MPS of most young adults. For older adults, these two values jump to 0.40 and 0.60 g/kg/meal.
Desirable minimal protein intake range per meal and age
| Body weight | |
|---|---|
| 3972 | 5482 |
The ranges in this table represent individual variations. The minimum protein requirements increase as you age, but to what degree is uncertain because of the age gap left by the studies: most subjects were in their 20s or 60s/70s . For people in their 30s, 40s, or 50s, the 0.290.53 g/kg range reflected in this table is an educated guess.References: Schoenfeld and Aragon. J Int Soc Sports Nutr. 2018. Rafii et al. J Nutr. 2016. Morton et al. Front Physiol. 2015. Moore et al. J Gerontol A Biol Sci Med Sci. 2015. Rafii et al. J Nutr. 2015.
Further, there are at least three good arguments in favor of eating toward or even above the higher end of your range:
How Many Grams Of Protein Per Day Do You Need
When it comes to following a healthy, balanced diet, a common question is: How much protein do I need? So how many grams of protein per day do you need?
High-protein foods are essential for building muscle, burning fat, supporting metabolism, and even bolstering the health of certain organs like your thyroid and adrenal glands in other words, we need protein to be healthy.
How much protein should you have per day? It really depends on your specific health goals and some other factors.

Chickpeas On Toast: 30 Grams
If you’re following a vegetarian or vegan diet, try a planet-based breakfast, like chickpeas on toast. Chickpeas pack about 15 grams of protein per cup, making them the perfect high-protein and vegan-friendly option.
Heat up two cups of cooked chickpeas, mixed with olive oil, shallots, garlic, and chopped tomatoes, on the stovetop. Toast a slice of your favorite bread and pile the chickpeas on top.
What Should You Do
Research on how much protein is the optimal amount to eat for good health is ongoing, and is far from settled. The value of high-protein diets for weight loss or cardiovascular health, for example, remains controversial.
Before you start ramping up your daily protein intake, there are a few important things to consider. For one, dont read “get more protein” as “eat more meat.” Beef, poultry, and pork can certainly provide high-quality protein, but so can many plant foods including whole grains, beans and other legumes, nuts, and vegetables. The table below provides some healthier sources of protein.
Its also important to consider the protein “package” the fats, carbohydrates, vitamins, minerals, and other nutrients that invariably come along with protein. Aim for protein sources low in saturated fat and processed carbohydrates and rich in many nutrients.
One more thing: If you increase protein, dietary arithmetic demands that you eat less of other things to keep your daily calorie intake steady. The switches you make can affect your nutrition, for better or for worse. For example, eating more protein instead of low-quality refined carbohydrates, like white bread and sweets, is a healthy choice though how healthy the choice is also depends on the total protein package.

Dietary Protein: Why When And How Much
May 06, 2022
Protein is one of the most important building blocks of your bodys muscles, bones, cartilage, skin and blood and is necessary for almost all of the bodys physiological functions. In addition to being an essential macronutrient, it may also serve as an energy source when the body cant utilize carbohydrates or fat.
So how much protein should you eat each day? That varies based on several factors your current weight, your gender and your goals. Do you want to build muscle? Maintain or lose weight? Look more toned? Eating the right amount and the right type of protein can help you achieve one or all of these desired outcomes.
Here’s Why Youre Probably Not Eating Enough Protein
The irony of the protein boom is that Americans arent actually ingesting any more of it today than they were 30 years ago.
That might be because proteins recommended daily allowance is a modest 0.8 grams per kilogram of body weight per day, a number formulated during World War II in order to safeguard public health during a possible shortage and ensure the nutritive value of military rations.
That RDA means roughly 8 to 10 percent of your daily intake should be protein, says Heather Leidy, Ph.D., a protein researcher and associate professor in Purdue Universitys Department of Nutrition Science.
But that 8 to 10 percent is only the minimum required to prevent a protein deficiency, not what you need for protein synthesis, muscle gain, satiety, weight management, and glycemic control.
While the diets of most Americans may contain between 10 and 15 percent protein, Leidy notes, research suggests that anywhere from 20 to 30 percent would be a better health goalwith at least 30 grams of protein being the minimum threshold at mealtime.
Another way to look at it: Thats between 1.2 and 1.6 grams of protein daily for every kilogram of your target body weight. So if youre a 185-pound guy who wants to weigh 165, you should eat between 90 and 120 grams of protein per day.
Actually, it’s pretty easy.

Best Time Of Day To Eat Protein
The protein you eat is most helpful to your body when eaten consistently at each meal to keep your energy levels up. In particular, protein intake is very beneficial at the following times:
- Morning: When you wake up in the morning, your body has already used up most of the nutrients you ate during your previous meal. Consuming protein first thing in the morning is a great way to get your energy back and get your day started on the right foot. Try adding eggs, milk, yogurt or cheese to your breakfast for an easy protein boost.
- Snacks: If you find yourself getting hungry between meals, a protein-dense snack might be just what you need to tide yourself over. Try a handful of almonds or a serving of Greek yogurt.
- After a workout: Eating protein within 30 minutes of completing your workout helps your muscles heal and build strength.
Prevalence Of Sarcopenia By Age And Sex In The Us
Reference: Janssen et al. J Am Geriatr Soc. 2002.
Fortunately, sarcopenia is neither inevitable nor irreversible some seniors have built more muscle in their old age than they ever had in their youth. The older you get, though, the greater your muscles anabolic resistance , and so the more protein you must eat to stimulate muscle protein synthesis.
The protein RDA for adults over 50 is currently the same as for younger adults: 0.8 g/kg. Same as for younger adults, however, studies using the method have suggested that 1.2 g/kg would be a more appropriate RDA. Moreover, since a low protein intake is associated with frailty and worse physical function than a higher protein intake, several authorities now recommend that older adults consume 1.21.5 g/kg. Finally, while all adults have similar daily protein requirements, older adults have higher .
Notably, doubling protein intake from 0.8 to 1.6 g/kg has been shown to significantly increase lean body mass in elderly men. Similar observations have been made in elderly women who increase their protein intake from 0.9 to 1.4 g/kg. Even a small increase in protein intake from 1.0 to 1.3 g/kg has minor benefits towards lean mass and overall body composition.
So how much protein should you get?
- Sedentary but healthy seniors: 1.01.2 g/kg
- Sick or injured seniors: 1.21.5 g/kg
- Seniors wishing to lose weight: 1.52.2 g/kg
- Seniors wishing to build muscle: 1.72.0 g/kg

Foods High In Protein
There are many different combinations of food that a person can eat to meet their protein intake requirements. For many people, a large portion of protein intake comes from meat and dairy, though it is possible to get enough protein while meeting certain dietary restrictions you might have. Generally, it is easier to meet your RDA of protein by consuming meat and dairy, but an excess of either can have a negative health impact. There are plenty of plant-based protein options, but they generally contain less protein in a given serving. Ideally, a person should consume a mixture of meat, dairy, and plant-based foods in order to meet their RDA and have a balanced diet replete with nutrients.
If possible, consuming a variety of complete proteins is recommended. A complete protein is a protein that contains a good amount of each of the nine essential amino acids required in the human diet. Examples of complete protein foods or meals include:

How Much Protein Do You Need Each Day
Current guidelines, established by the Institute of Medicine in 2002, recommend adults 19 years of age and older consume 10% to 35% of their daily calories from protein, according to a 2005 report in Current Sports Medicine Reports. That’s about 200 to 700 calories from protein for a 2,000-calorie diet. Another way to calculate how much protein you need each day is to multiply 0.8 grams of protein per kilogram of your body weight. With a little math, this translates to 54 grams of protein for a 150-pound female or 65 grams for a 180-pound male.
Here are some examples of what 10 grams of protein looks like:

Eat More If You’re Trying To Build Muscle
You need a lot of protein to build muscle with resistance training.
A 2022 research analysis found that 1.5 grams per kilogram of body weight, or .68 grams per pound, was the sweet spot for building or maintaining muscle while training.
For a 150-pound person, that would be 102 grams of protein per day.
The analysis found that more protein than that didn’t reap further rewards. The authors also noted that people didn’t gain muscle just by adding extra protein. They had to be resistance training, too.
Upping your protein intake can help you make gains regardless of your age, weight, height, and other factors as long as you are doing resistance training.
Make Every Meal Count
Some nutritionists believe that when you eat your protein is every bit as important as how much you’re getting. For instance, the typical American’s intake is weighted toward the end of the day say, in a chicken breast or fish at dinner but this may not be the most efficient way to process the macronutrient.
“We’re always building protein and breaking it down it’s dynamic, says Rodriguez. Spreading your protein intake throughout the day stops muscle from breaking down intermittently during the day. A study in the American Journal of Clinical Nutrition found that those ages 67 to 84 who evenly distributed their protein consumption throughout the day tended to have stronger muscles than those who packed their protein into a single meal.

Does Protein Have Any Negative Health Effects
Protein has been unfairly blamed for a number of health problems.
Some people believe that a high protein diet can cause kidney damage and osteoporosis, but science does not support these claims.
Though protein restriction is helpful for people with preexisting kidney problems, theres no evidence that protein can cause kidney damage in healthy people (
31 ).
Overall, theres no evidence that a reasonably high protein intake has any adverse effects in healthy people trying to optimize their health.
Summary
Protein does not have any negative effects on kidney function in healthy people, and studies show that it leads to improved bone health.
The best sources of protein are meats, fish, eggs, and dairy products, as they have all the essential amino acids that your body needs.
Some plants are fairly high in protein as well, such as quinoa, legumes, and nuts.
However, most people generally dont need to track their protein intake.
If youre healthy and trying to stay that way, simply eating quality protein sources with most of your meals, along with nutritious plant foods, should bring your intake to an optimal range.
How Much Fat Should I Eat
A diet that is moderate in fat content is important for maintaining a healthy weight and preventing heart disease and stroke while providing adequate and essential nutrients. The Institute of Medicine and the American Heart Association recommend a total fat intake of 25-35 percent of calories. Thats about 80 grams of fat or less a day if you eat 2,000 calories a day.

How Much Fat Protein And Carbs Should You Be Eating
Experts break down what a healthy diet should really look like
First, we feared eating too much fat. Then, the pendulum shifted, and we started to eye carbs as the enemy. But whats the real deal?
Now, a global study published in The Lancet is challenging the notion that one necessarily needs to be worse than the other: Rather, it might be that eating too much or too little of the nutrients is the actual problem.
Researchers from McMaster University in Canada followed more than 135,000 people in 18 countriesfrom South America to Africa to Chinafor about seven years. After analyzing survey data about their diet and health, the researchers found that people who ate more than 68 percent of their total calories from carbohydrates were 28 percent more likely to die during the follow up than those who took in a lesser percentage of their calories from carbs.
While the researchers didnt look into the specific types of carbs these people were eating, its safe to assume based on past research that a large chunk of those carbs are refined ones, like white bread and rice, says lead study author Mahshid Dehghan, MS.c., Ph.D., especially when you consider countries with higher levels of poverty.
