Optimal Daily Protein Intake For Children
The protein RDA is slightly higher for children than for adults: 0.95 versus 0.8 g/kg. This difference makes sense considering that children are still growing and need more protein to facilitate the process. , however, the RDA may underestimate true requirements.
Use of the technique in children aged 611 years has suggested that around 1.5 g/kg would make for a more appropriate RDA. Protein requirements are likely higher in children involved in sports and other athletic activities.
There are no long-term studies on optimal protein intake since it would be unethical to deprive children of the protein they need for their development and various physiologic and metabolic functions.
Children require at least 1.5 grams of protein per kilogram of body weight per day . An unknown amount of additional protein is likely required by children who are involved in sports or otherwise regularly active.
Leucine Content Of Plant And Animal Proteins
Reference: van Vliet et al. J Nutr. 2015
Plant proteins being lower in leucine and other EAAs helps explain why several studies have reported lower MPS from soy protein powders and beverages than from whey protein, skim milk, whole milk with cheese, and lean beef.
The quality of a protein depends on its bioavailability and EAA content. Based on both criteria, the quality of plant proteins is lower than the quality of animal proteins.
Nutritional Value Of Protein
The nutritional value of a protein is measured by the quantity of essential amino acids it contains.
Different foods contain different amounts of essential amino acids. Generally:
- Animal products have all of the essential amino acids and are known as ‘complete’ protein .
- Soy products, quinoa and the seed of a leafy green called amaranth also have all of the essential amino acids.
- Plant proteins usually lack at least one of the essential amino acids and are considered ‘incomplete’ proteins.
People following a strict vegetarian or vegan diet need to choose a variety of protein sources from a combination of plant foods every day to make sure they get an adequate mix of essential amino acids.
If you follow a vegetarian or vegan diet, as long as you eat a wide variety of foods, you can usually get the protein you need. For example, a meal containing cereals and legumes, such as baked beans on toast, provides all the essential amino acids found in a typical meat dish.

Why Is It Important To Select A Variety Of Choices From The Protein Foods Group
Protein foods provide nutrients important for maintaining your health and body.
Many Americans get the right amount of protein needed from meat, poultry, and eggs, but do not meet the recommendations for seafood or nuts, seeds, and soy products. Meeting this can help increase the amount of important nutrients your body needs, like unsaturated fats, dietary fiber, and vitamin D. It also helps limit the amount of sodium and saturated fats from you get from processed meat and poultry.
Research On Protein And Health
Available evidence indicates that its the source of protein , rather than the amount of protein, that likely makes a difference for our health. You can explore the research related to each disease in the tabs below, but heres the evidence-based takeaway: eating healthy protein sources like beans, nuts, fish, or poultry in place of red meat and processed meat can lower the risk of several diseases and premature death.
Research conducted at the Harvard Chan School of Public Health has found that eating even small amounts of red meatespecially processed red meaton a regular basis is linked to an increased risk of heart disease and stroke, and the risk of dying from cardiovascular disease or any other cause. Conversely, replacing red and processed red meat with healthy protein sources such as beans, soy foods, nuts, fish, or poultry seems to reduce these risks. One of the reasons why plant sources of protein are related to lower risk of cardiovascular disease compared to protein from red meat and dairy is because of the different types of fat in these protein packages. Plant-based protein sources are more unsaturated, which lowers LDL cholesterolan established risk factor for heart disease. Also, plant sources contain no cholesterol. Other factors are likely to contribute to the lower risk, but this is a key factor.

How Much Protein You Need
The recommended intake value for protein is 0.8 grams per kilogram of body weight. Once you know how much protein you need, you can build a meal plan that incorporates the high-protein foods you like best to meet your needs. While chicken, fish, and red meat may be the most obvious dietary protein sources, if you follow a vegetarian or vegan diet, you can get protein from plant sources like beans, nuts, and seeds.
One ounce of lean beef, pork, skinless poultry, fish, or shellfish provides about 7 grams of protein. For other protein-containing foods, the following serving sizes are roughly equivalent to 1 ounce of meat.
- 1/2 ounce nuts or seeds
- 1 tablespoon peanut butter
- 1/4 cup cooked beans, green peas, or tofu
- 4 oz. falafel patty
These guidelines are general. The amount of protein in each food source can vary, especially according to how they’re prepared and cooked. You can use this method of counting servings in place of counting grams.
The information below lists the amount of protein found in 100 grams of each food product. In this way, you can directly compare how protein-dense different foods are. However, keep in mind that 100 grams might not be the right serving size of each food. For reference, 3 ounces, which is a common serving size measure for meat like chicken or beef, is 85 grams.
How Much Protein After Exercise
After exercising, when your muscles are more sensitive to the anabolic effect of protein, take a dose in the range of your . If youve been exercising on an empty stomach, youll be in negative protein balance, so take this dose as soon as possible. Otherwise, try to take it within a couple of hours the exact size of your window of opportunity depends on how much protein youre still digesting.

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
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:

Do New Zealanders Get Enough Protein
Most of us easily meet the RDI for protein. Even vegans and vegetarians who eat a relatively balanced diet can easily get enough protein in their diet. In saying that, a lot of us dont distribute protein well throughout the day- we tend to eat little at breakfast, a bit more at lunch and then a significant amount at dinner time. Ideally, we should focus on having a good serving of protein at each meal. This helps keep hunger at bay and helps muscle growth/retention .
Digging Deeper: After Better Than Before
Is it better to eat before or after exercising?
In a 2020 crossover trial we first summarized for Examine Members, 8 healthy young men were divided into three groups.
All three groups performed a full-body strength workout in the morning. One group ate a meal 1.5 hours before, another just after, and the last waited for lunchtime.
This happened three times, with three days in between. Each time, the men switched to a different group. Thus, at the end of the trial, they had all tried all three meal times.
Blood insulin and certain modified amino acids were measured as indicators of muscle breakdown. The results? Eating a mixed-nutrient meal immediately after resistance training, rather than 1.5 hours before or not until lunchtime, resulted in the greatest suppression of muscle protein breakdown.
Whether or not this correlates with improvements in muscle growth and recovery, however, is unclear.

Despite being thought of as meat for the holiday season, turkey can be the centerpiece of a nutritious meal at any time of the year.
Optimal Daily Protein Intake For Healthy Sedentary Adults
For adults, the US Recommended Dietary Allowance for protein is 0.8 g/kg. However, a more appropriate statistical analysis of the data used to establish the RDA suggests this number should be higher: 1.0 g/kg.
Note that, contrary to popular belief, the RDA doesnt represent an ideal intake. Instead, it represents the minimum intake needed to prevent malnutrition. Unfortunately, the RDA for protein was determined from nitrogen balance studies, which require that people eat experimental diets for weeks before measurements are taken. This provides ample time for the body to adapt to low protein intakes by down-regulating processes that are not necessary for survival but are necessary for optimal health, such as protein turnover and immune function.
An alternative method for determining protein requirements, called the Indicator Amino Acid Oxidation technique, overcomes many of the shortcomings of nitrogen balance studies. Notably, it allows for the assessment of protein requirements within 24 hours, thereby not leaving the body enough time to adapt. Studies using the IAAO method have suggested that about 1.2 g/kg is a more appropriate RDA for healthy young men, older men, and older women.
Further evidence that the current RDA for protein is not sufficient comes from a randomized controlled trial that confined healthy, sedentary adults to a metabolic ward for eight weeks. The participants were randomized into three groups:

Grams Of Protein For Vegetarians
For vegetarians, 100 grams of protein might look like:
- ½ cup of rolled oats
- Two tablespoons of peanut butter
- One tablespoon of hemp seeds
- ¼ cup of protein granola
- One scoop of plant-based protein powder
- Two snack cheeses
- A single-serve Greek yogurt
This actually comes out to 99 grams of protein, which is pretty dang close and still a great number to hit for a day.
Which Foods Contain Protein
Protein is found in both animal and plant foods.
- Animal sources: meat, fish, chicken, eggs, milk, cheese and yoghurt.
- Plant sources: soy protein , grains , nuts and pulses .
Protein is made up of 20 amino acids. While all 20 of these are important for your health, 9 are classified as essential and 11 as non-essential.
- Essential amino acids cannot be made by the body and thus must come from food
- Non-essential amino acids can be made by our body
All animal foods, as well as soybeans , provide all 9 essential amino acids in sufficient quantities and are classified as complete proteins. All other plant-based sources of protein lack one or more of the essential amino acids and are called incomplete proteins. People who follow a plant-based diet should eat a variety of plant sources of protein every day to get all the essential amino acids.

Different Brands Have Different Scoops
Brands have their own approaches to manufacturing the protein powder, and there are so many brands in the world, so you can imagine the diversity. To put it shortly, different manufacturers have different processes, so they have to use different scoops.
In the end, it all boils down to how densely the protein is packed in a scoop and how much protein powder is heaped from a scoop.
How Much Protein Do You Need
The reference dietary intake of protein is between 46-63 grams for most adults, with pregnant and lactating women needing up to 65 grams per day. The daily value for protein is set at 50 grams per day , which is an average that works for most people. Athletes or other people looking to build muscle mass may want to consume more protein.
High protein foods include lean chicken, lean pork, fish, lean beef, tofu, beans, lentils, low-fat yogurt, milk, cheese, seeds, nuts, and eggs.

Lentils: 258 G Protein Per 100 G
Many plant-based foods that claim to be high in protein are not significant sources.
For example, broccoli is often promoted as a âprotein-richâ vegan option. In reality, it contains less than three grams per 100 g.
In contrast, lentils genuinely are rich in protein. They are not a complete protein regarding their amino acid content, but they are one of the best sources for those who donât eat meat.
A 1/2 cup serving provides around 25 grams of protein.
Lentils are also one of the best foods for people who prefer a higher carb diet, and they offer a good source of essential nutrients like iron, magnesium, and potassium.

Peanut butter can also boost the flavor and nutritional value of firm fruits like apples and pears, which are rich in fiber and antioxidants yet low in protein.
In fact, spreading 2 tablespoons of peanut butter on sliced fruit can boost the total protein content by 7 grams .
Peanut butter also works well with a wide range of other ingredients, including oatmeal, celery, whole wheat toast, or yogurt.
Adding peanut butter to your diet can boost your protein intake. It may also help decrease appetite, improve heart health, and lower blood sugar.
Low Fat Cottage Cheese
Cottage cheese is a high protein, low fuss food.
A 1-cup serving of low fat cottage cheese has 163 calories, 2.5 grams of fat, and 28 grams of protein .
The newest trends in cottage cheese include single-serve containers, flavored options, and the addition of live and active probiotic cultures.
Besides protein, you get around 1015% of the RDI for calcium in 1/2 cup of cottage cheese. Some food scientists have recently suggested that manufacturers add vitamin D, which aids calcium absorption, though this is not currently common practice .
Low fat cottage cheese is an excellent source of protein and is becoming even more convenient with the increased availability of single-serving containers. Its also a good source of calcium.
