Consuming adequate protein about 1. Protein is an essential component of muscles and bones. Your bones are made primarily of a type of protein called collagen. Therefore, a protein deficiency can decrease muscle and bone massleading you to feel tired and weak.
Protein from calcium-rich foods is required for bone growth, especially for young children. Bone mass, or bone mineral density BMD is largely genetic. Consuming adequate protein helps children reach their optimum genetic potential for bone mass.
Protein is also important for bone maintenance in older adults who have or are at a higher risk of osteoporosisa condition that causes porous, weak bones that break easily. One meta-analysis of 13 studies found that adults over the age of 65 with a higher protein intake had a lower risk of bone fractures.
Protein is essential for growth. This is one of the symptoms of kwashiorkor. Growth stunting can affect health and well-being in multiple ways, including:.
It's important to treat protein deficiency early, especially in children. Early treatment can reduce the risk of complications like permanent physical disabilities. Many factors can contribute to weight loss as a result of protein deficiency.
People who have marasmus may experience reduced heart function, which can lead to weight loss. Eating a lower protein diet can also lead to weight gain.
For example, protein is often more satiating than carbohydratesmeaning you feel full for longer periods of time after eating protein.
Therefore, eating more protein might lead to lower caloric intake overall. More research is needed to determine how protein affects weight, but shorter-term research studies demonstrate that a high-protein diet can contribute to weight loss and prevent weight regain.
Anemia is a common symptom of marasmus. Anemia is a condition where your body has a reduced number of red blood cells or hemoglobinthe protein that helps your red blood cells transport oxygen from your lungs to the rest of your body.
Your body needs iron to make oxygen-rich red blood cells. Anemia is often treated with iron supplements or by eating more iron-rich foods. About one billion people worldwide do not get enough protein in their diets. Protein deficiency is not very common in the United States. However, some people are at a higher risk, including:.
Protein needs vary depending on factors like age, weight, and physical activity levels. In the U. The RDA is the minimum amount of protein necessary to prevent muscle loss. Many people require more protein to maintain optimal health. Here are some basic protein recommendations:.
Not everyone should consume high amounts of protein in their diet. For example, too much protein can negatively affect conditions like kidney disease. Talk to your healthcare provider about how much protein you need. There are plenty of animal and plant-based protein protein sources from which to choose.
Animal sources of protein include:. Plant-based sources of protein include:. Try to limit red meat and processed meat, as high amounts can increase your risk of conditions like heart disease. Also, talk to your healthcare provider before trying protein powders or supplements.
Dietary supplements are minimally regulated by the FDA, and their effects vary from person to person. If you're concerned about your protein intake, try adding at least one protein source to every meal and snack, starting with breakfast.
For example:. Reach out to your healthcare provider if you're concerned you may not be getting enough protein in your diet or if you or someone in your care has symptoms of kwashiorkor or marasmus.
Getting medical care early on can help prevent possible complications. Your healthcare provider might also refer you to a registered dietician RDa certified healthcare professional who specializes in nutrition.
Protein is essential to health. It helps with growth and development, and it helps repair cells and make new ones. Protein deficiency can cause symptoms such as swelling, stunted growth, a weakened immune system, skin and hair changes, and bone and muscle loss.
The amount of protein you need depends on factors like age and activity levels. You can get more protein in your diet by adding foods like beans and legumes, meat, seafood, eggs, and nuts.

Zinc is required for bone tissue renewal and mineralization. Severe deficiency is usually associated with calorie and protein malnutrition and has been reported to be common in community-dwelling older people. Milder degrees of zinc deficiency have been reported in the elderly and could potentially contribute to poor bone status [12] Kvamme, J. Public Health Nutr, Sources of zinc include lean red meat, poultry, whole grain cereals, pulses, legumes and dried fruit. The role of vitamin A in osteoporosis is controversial. Consumption of vitamin A in amounts well above the recommended daily intake may have adverse effects on bone [13] Tanumihardjo, S. Such high levels of vitamin A intake are probably only achieved through over-use of supplements, and intakes from food sources are not likely to pose a problem. Further research is needed into the role of vitamin A in bone health, although many countries at present caution against taking a fish liver oil supplement and a multivitamin supplement concurrently. For both men and women, more than two units per day of alcohol can increase the risk of a fragility fracture, while more than four units per day can double fracture risk [14] Kanis, J. Up to two mL glasses of wine per day do not negatively impact on bone health. Caffeine increases urinary and faecal calcium losses and so, in combination with a diet low in calcium, has the potential to adversely affect bone health.

Protein intake for preventing nutrient deficiencies -
This is graphically indicated by metabolic disorders, kwashiorkor caused by a severe deficiency of protein and marasmus caused by the severe deficiency of both protein and energy in humans, particularly in many children of developing nations.
Knowledge about AA biochemistry and nutrition provides the necessary foundation to optimize the recommended values for dietary requirements of protein by humans and to understand the potential impacts of dietary protein on health.
Nitrogen balance studies have traditionally been employed to determine the requirements of dietary protein and AA by humans. In recent years, there has been growing interest in the dietary requirements of synthesizable AA by mammals, including humans. Let us use histidine and arginine as examples to illustrate some shortcomings of N balance studies.
The results of the N balance studies by Rose did not reveal the dietary requirements of histidine or arginine by healthy adults. Extending the experimental period of feeding a histidine-free diet from 8 to 28 days or longer substantially reduces the endogenous release of histidine from hemoglobin and intramuscular small peptides, thereby resulting in a negative N balance in adults.
In addition, extensive studies with pregnant dams have shown that dietary arginine is required for the optimal survival and growth of embryos and fetuses. Despite its shortcomings, the N balance approach remains an invaluable procedure for determining the dietary requirements of AA and proteins for humans.
There is often confusion about either the energy value of protein or dietary protein intake as a percentage of energy intake in human nutrition. The gross calories of fat, protein, and starch, as determined in bomb combustion, are 9.
The amounts of energy released from the oxidation of fat, protein, and starch to water and CO 2 in vivo are 9. The resting metabolic rate RMR of healthy humans, expressed as kcal per kg BW per day, decreases with age, ranging from 55 kcal per kg BW per day in the 5-year-old to 25 kcal per kg BW per day in the year-old.
For example, a year-old adult with minimum physical activity would need 30 kcal energy per kg BW per day 1. The dietary requirements of AA and protein are affected by: a dietary factors e.
These factors should be taken into consideration in estimating the human requirements for dietary AA. Recent studies have shown that the N balance-based estimates of dietary AA requirements by humans are considerably lower than the values obtained by the AA oxidation methods.
The differences can be up to 2- to 3-fold for many EAA Table 2. These discrepancies may result from both methodological and physiological factors. This is clearly a limitation, as synthesizable AA are more abundant than EAA in tissues e. On the other hand, the use of tracers in metabolic research has potential problems associated with label dilution, isotope exchange, determination of intracellular specific activities of immediate precursors, and isotopic steady states.
Additionally, considerations should be given to dietary requirements of synthesizable AA. These values are expected to provide a much-needed database for future research on human protein nutrition. The RDA represents only minimum daily average dietary intake that meets the nutrient requirements of nearly all In this regard, it is noteworthy that skeletal muscle is the major reservoir of AA in the body and undergoes decreases in both mass and physical strength with aging.
Several lines of evidence show that the current RDA of protein is insufficient for adult humans with minimum physical activity.
First, elderly adults who consumed diets providing 0. During exercise, there is a negative balance between the rates of protein synthesis and breakdown in the whole body, as well as an increase in the rate of whole-body AA oxidation, resulting in a transient catabolic state.
Even moderate exercise e. Unless sufficient dietary protein is consumed during recovery for increased synthesis of muscle proteins, protein degradation will exceed protein synthesis, resulting in a loss of muscle mass and negative N balance.
In support of this view, healthy adults who performed intensive exercise daily 9. When the dietary intake of AA and energy is sufficient during a prolonged post-exercise period of recovery, a positive protein balance occurs in the whole body including skeletal muscle.
In adequately fed subjects, the overall chronic responses of protein metabolism to regular exercise are anabolic and beneficial for inducing skeletal-muscle hypertrophy, improving muscle protein-mass and function, and preventing muscle wasting.
Recently, ACSM, the American Dietetic Association, and Dieticians of Canada recommended that endurance-training moderate exercise athletes and strength-training intense exercise athletes consume 1.
Children need protein to build muscles, gain height, and optimize brain functioning. Children experiencing nutritional deficiencies may exhibit fussiness, behavioral issues, or even chronic episodes of anxiety and depression. Therefore, a protein-rich diet is advisable, as protein contains amino acids essential for optimal brain function.
Encourage protein intake from plant or animal sources to fulfill this important need in your child. Teach Them To Say No To Processed Food: Hyperactivity in children is often related to issues with the digestive system.
Many doctors suggest that children with hyperactivity or ADHD should avoid processed foods and food dyes. Excessive sugar and salt intake are often identified as contributing factors to hyperactivity, so reducing the consumption of sugary and processed snacks is advised.
Increase Fibre Intake: Another often neglected food group consists of dietary fibers, primarily found in the indigestible portions of fruits and vegetables, mainly composed of cellulose.
Insufficient intake of vegetables can lead to low energy and a weakened immune system. These fibers are crucial in promoting intestinal health. Aim to incorporate at least one serving of vegetables into three daily meals.
When it comes to food groups, fats often receive the most avoidance. Humans possess two types of immunity: innate and adaptive. Innate immunity is a first-line defense from pathogens that try to enter our bodies, achieved through protective barriers. These barriers include:.
Adaptive or acquired immunity is a system that learns to recognize a pathogen. It is regulated by cells and organs in our body like the spleen, thymus, bone marrow, and lymph nodes.
When a foreign substance enters the body, these cells and organs create antibodies and lead to multiplication of immune cells including different types of white blood cells that are specific to that harmful substance and attack and destroy it.
Our immune system then adapts by remembering the foreign substance so that if it enters again, these antibodies and cells are even more efficient and quick to destroy it. Antigens are substances that the body labels as foreign and harmful, which triggers immune cell activity.
Allergens are one type of antigen and include grass pollen, dust, food components, or pet hair. Antigens can cause a hyper-reactive response in which too many white cells are released.
For example, an allergy to mold triggers symptoms of wheezing and coughing in a sensitive individual but does not trigger a reaction in other people. When pathogens attack healthy cells and tissue, a type of immune cell called mast cells counterattack and release proteins called histamines, which cause inflammation.
Inflammation may generate pain, swelling, and a release of fluids to help flush out the pathogens. The histamines also send signals to discharge even more white blood cells to fight pathogens. However, prolonged inflammation can lead to tissue damage and may overwhelm the immune system.
Autoimmune disorders like lupus, rheumatoid arthritis, or type 1 diabetes are partly hereditary and cause hypersensitivity in which immune cells attack and destroy healthy cells. Immunodeficiency disorders can depress or completely disable the immune system, and may be genetic or acquired.
Acquired forms are more common and include AIDS and cancers like leukemia and multiple myeloma. Eating enough nutrients as part of a varied diet is required for the health and function of all cells, including immune cells.
Certain dietary patterns may better prepare the body for microbial attacks and excess inflammation, but it is unlikely that individual foods offer special protection.
Examples of nutrients that have been identified as critical for the growth and function of immune cells include vitamin C, vitamin D, zinc, selenium, iron, and protein including the amino acid glutamine. Diets that are limited in variety and lower in nutrients, such as consisting primarily of ultra-processed foods and lacking in minimally processed foods, can negatively affect a healthy immune system.
It is also believed that a Western diet high in refined sugar and red meat and low in fruits and vegetables can promote disturbances in healthy intestinal microorganisms, resulting in chronic inflammation of the gut, and associated suppressed immunity.
The microbiome is an internal metropolis of trillions of microorganisms or microbes that live in our bodies, mostly in the intestines. It is an area of intense and active research, as scientists are finding that the microbiome plays a key role in immune function.
The gut is a major site of immune activity and the production of antimicrobial proteins. A high-fiber plant-rich diet with plenty of fruits, vegetables, whole grains, and legumes appear to support the growth and maintenance of beneficial microbes.
Certain helpful microbes break down fibers into short chain fatty acids, which have been shown to stimulate immune cell activity. These fibers are sometimes called prebiotics because they feed microbes. Therefore, a diet containing probiotic and prebiotic foods may be beneficial.
Probiotic foods contain live helpful bacteria, and prebiotic foods contain fiber and oligosaccharides that feed and maintain healthy colonies of those bacteria. Animal studies have found that deficiencies in zinc , selenium , iron , copper, folic acid , and vitamins A , B6 , C , D , and E can alter immune responses.
Epidemiological studies find that those who are poorly nourished are at greater risk of bacterial, viral, and other infections. Eating a good quality diet, as depicted by the Healthy Eating Plate, can prevent deficiencies in these nutrients.
However, there are certain populations and situations in which one cannot always eat a variety of nutritious foods, or who have increased nutrient needs. In these cases a vitamin and mineral supplement may help to fill nutritional gaps.
Studies have shown that vitamin supplementation can improve immune responses in these groups. The elderly are a particularly high-risk group. The immune response generally declines with increasing age as the number and quality of immune cells decreases.

According to the Food and Drug Administration FDAmost people in the United States get enough protein from their diets to meet their needs. This article looks at protein, its function, sources, and how much protein different groups of people need each day.
