Fats, carbohydrates (including fiber, sugar, and starch), vitamins, and minerals, along with protein, are essential components that should always be part of one’s diet. These nutrients ensure that the body receives a well-rounded supply of essential elements for growth and overall health. In fact, the proportions of these nutrients can be adjusted to suit individual needs.
A common dietary approach involves reducing carbohydrate intake while increasing protein consumption. Numerous studies have demonstrated that a high-protein diet offers significant health benefits, particularly in terms of metabolic activity and promoting height growth in children and adolescents.
What is Protein?
Protein is one of the three main food groups. It is composed of amino acids and serves as the ‘building blocks’ of cells. Cells require protein for growth and self-repair. Protein can be found in various types of foods, such as meat, fish, poultry, eggs, various legumes, and dairy products.

Protein can be found in meat, fish, eggs, milk, cereals, and more.
To ensure that your body receives the necessary amount of protein, it is recommended to consume at least 0.8 grams of protein per kilogram of body weight.
In case you want to modify your diet, focusing on a higher protein intake for weight loss, you should supplement your protein intake according to the following recommendations:
(EAR: Estimated Average Requirement; RDI: Recommended Dietary Intake)
For Males:
Age Group | EAR (Estimated Average Requirement) | RDI (Recommended Dietary Intake) |
---|---|---|
4 – 8 | 16 grams | 20 grams |
9 – 13 | 31 grams | 40 grams |
14 – 18 | 49 grams | 65 grams |
19 – 70 | 52 grams | 64 grams |
Over 70 | 65 grams | 81 grams |
For Females:
Age Group | EAR (Estimated Average Requirement) | RDI (Recommended Dietary Intake) |
---|---|---|
4 – 8 | 16 grams | 20 grams |
9 – 13 | 24 grams | 35 grams |
14 – 18 | 35 grams | 45 grams |
19 – 70 | 37 grams | 46 grams |
Over 70 | 46 grams | 57 grams |
Both protein deficiency and excess can have consequences for health. For instance, protein deficiency can lead to muscle wasting, stunted growth, and cardiovascular problems, among other issues. On the other hand, excessive consumption of protein-rich foods can result in bone fragility and dehydration.
How Does Protein Affect Height Development?
There is a common misconception that consuming high amounts of protein can be detrimental to bone health. Specifically, it’s often thought that higher protein intake leads to increased acidity in the body, causing calcium to be leached from bones in order to neutralize the acidity. However, long-term studies on protein have shown quite the opposite. Protein, including animal protein, has been found to have positive effects on bone health and support height development in adolescents during their growth years.
Individuals who consume more protein often tend to maintain better bone mass. Moreover, bone-related conditions such as bone degeneration, osteoporosis, and fractures are significantly reduced.

Supplementing Adequate Protein for Healthy Bones and Joints.
This is particularly important for individuals at risk of osteoporosis, especially postmenopausal women. To maintain strong and healthy bones, it is advisable to incorporate a high-protein diet along with physical activities.
Protein is widely recognized as a key component for muscle health. When the body receives an adequate amount of protein, muscle mass and muscle health are better sustained.
A study conducted on healthy adults (aged 18-59) to assess the impact of protein on muscle mass showed that a high-protein diet had positive effects, promoting muscle hypertrophy and increased muscle strength from the second week onwards.
A study by Purdue University found that individuals on a high-protein diet for weight loss experienced improved sleep. This conclusion was drawn from various small-scale studies.
A pilot study involving 14 participants revealed that those who consumed a high-protein diet had better sleep after 4 weeks of following the regimen. Quality sleep plays a crucial role in height development. When children and adolescents get sufficient, restful sleep, growth hormone production from the pituitary gland is optimized, contributing to better height development.
The main study was conducted on 44 overweight or obese individuals divided into two groups: one consuming a higher protein diet and the other a normal diet. After 3 weeks, the group consuming 0.8-1.5 grams of protein per kilogram (approximately 0.012699-0.023986 ounces per pound) of body weight reported significantly improved sleep quality.
One of the consequences of aging is muscle weakening. Age-related decline in physical activity is a major factor leading to weakened bone and muscle systems in both the elderly and young individuals. Bone turnover rates also slow down, meaning height improvement opportunities are limited.

Protein has a significant impact on the height development of children and adolescents.
Consuming higher protein and maintaining physical activity are the best ways to mitigate age-related muscle weakening and prevent muscle loss conditions. Weight-bearing exercises like weightlifting can be particularly effective in addressing these issues.
It’s evident that muscles are predominantly composed of protein. Consuming more protein can help enhance muscle mass and strength, thus promoting significant height growth. The necessary protein intake for the body depends on various factors, including body weight, muscle mass, physical activity level, gender, and age.

Which Foods Help Supplement Protein for the Body
Food is the primary source of nutrients for the body, including protein. There are numerous high-protein foods that you can incorporate into your diet to provide essential protein for your body.

You can incorporate the following foods into your high-protein diet.
Eggs (chicken eggs, duck eggs)
You may not be aware that egg whites are nearly pure protein. This characteristic makes eggs an excellent source of protein for the body. According to nutritionists, there are approximately 12.58 grams of protein in 3.5 ounces of eggs.
