Protein is an essential macronutrient that supplies indispensable amino acids that our bodies cannot synthesize on their own. While protein is crucial for proper growth, development, and overall health, there is growing evidence that Americans are consuming more protein than they need. This overconsumption of protein can lead to an imbalance in macronutrients and an increased risk of health issues such as kidney damage, heart disease, and certain types of cancer. On the other hand, some experts suggest that the standard recommendations for protein intake may be too low, especially for active individuals trying to build muscle mass. This has led to a widespread obsession with protein, with many Americans focusing on ensuring they get enough in their diets.
| Characteristics | Values |
|---|---|
| Recommended protein intake | 15-30 grams per meal |
| Recommended daily allowance | 0.8 grams per kilogram of body weight |
| Average protein intake by Americans | Double the recommended amount |
| Health risks of high protein intake | Kidney damage, heart disease, cancer |
| Health risks of low protein intake | Malnutrition, loss of muscle mass |
| Healthier sources of protein | Plant-based proteins, salmon, yogurt, beans |

What You'll Learn
Americans are obsessed with protein
This obsession with protein may be somewhat warranted, as protein deficiency can be a serious health risk and is a common cause of malnutrition in other parts of the world. Protein is a macronutrient, meaning it is required in large amounts in the diet for proper growth, development, and overall health. However, it is very rare for people to be protein deficient in the United States, and most Americans are getting more than enough protein. In fact, Americans on average get about double the protein they need, with men in particular exceeding their protein recommendations, especially from meat, poultry, and eggs.
The obsession with protein can have negative consequences, as overloading your diet with protein can mess up your macronutrient balance. Eating high amounts of protein is usually achieved by consuming large amounts of meat and dairy products, which are often high in saturated fat and low in fiber. This can increase the risk of heart disease and other health conditions. Additionally, very high protein diets have been linked to a higher risk of kidney stones and kidney damage.
While protein is essential for growth and development, it is important to focus on getting protein from a variety of sources, including plant-based proteins such as beans, grains, soy, nuts, and seeds, which are lower in saturated fat and high in fiber and other micronutrients. It is also important to remember that protein should accompany fruits, vegetables, and whole grains, not make up your entire meal.

The risks of protein deficiency
Protein is a fundamental nutrient for maintaining good health, and a deficiency can have a significant impact on your well-being. While severe protein deficiency is rare in the developed world, it is a leading cause of death among children in many poor, underdeveloped countries. Protein deficiency can lead to serious health complications and nutritional imbalances.
There are two main syndromes associated with protein deficiencies: Kwashiorkor and Marasmus. Kwashiorkor, which means "rejected one" in a language spoken in Ghana, affects millions of children worldwide. It occurs when children are weaned from breastfeeding and switched to a diet of watery porridge made from low-protein grains. These children consume enough calories but not enough protein.
Protein deficiency can also lead to muscle atrophy, where muscle fibers break down and lose strength, resulting in weakness and a decline in mobility. It can compromise the immune system, making individuals more susceptible to infections and illnesses, and increasing recovery times. In children, protein deficiency can cause stunted growth, delayed development, and long-term developmental problems.
Additionally, a lack of protein can lead to liver and kidney damage as the body struggles to maintain normal functions without adequate protein. Other signs of protein deficiency include fatigue, hair loss, skin issues, and slow wound healing.
It is important to note that the amount of protein needed varies depending on age, activity level, and overall health. Experts recommend a daily intake of at least 0.36 grams of protein per pound of body weight (0.8 grams per kg), but this may not be sufficient for active individuals or those trying to build muscle mass. While most people in the U.S. meet or exceed their protein needs, certain groups such as adolescent girls and boys, the elderly, and those on restrictive diets may be at risk of low protein intake.

The health risks of too much protein
While protein is an essential part of our diet, it is possible to have too much of it. Excessive protein intake would be more than 2 grams per kilogram of body weight each day. Consuming more than 22 percent of daily calories from protein carries more downside risk than dietary benefit. For a normal adult, 20 to 30 grams of protein per meal, or 60 to 90 grams of protein per day is adequate to support health.
Consuming too much protein can lead to adverse cardiovascular and metabolic health effects. Specifically, a diet high in protein can increase the risk of heart attack and stroke. This is because excessive protein intake increases the production of macrophage cells, which, when overactive, can cause plaque buildup and blockages in the vascular system.
A high-protein diet that contains a lot of red meat and saturated fat might also lead to a higher risk of heart disease and colon cancer. People who eat very high-protein diets also have a higher risk of kidney stones.
It is important to note that the recommended amount of protein may vary depending on individual factors such as weight, activity level, and health conditions. For example, active people who are trying to build muscle mass may need more protein. If you are concerned about getting enough protein or considering a high-protein diet, it is advisable to consult with a dietitian or doctor to determine the right amount for your specific needs.

The benefits of plant-based proteins
While some people in the US may need to consume more protein, most people in the country already meet or exceed their protein requirements. This is especially true for men aged 19 to 59, who often exceed their protein recommendations, particularly from meat, poultry, and eggs.
With that being said, here is some information on the benefits of plant-based proteins:
Plant-based proteins offer a range of health benefits. They are typically lower in fat and provide additional nutrients like fibre, vitamins, and antioxidants. For example, beans contain fibre, which has been linked to improving digestive health and reducing the risk of certain conditions. Plant proteins can also aid in weight management as they increase satiety, meaning you feel fuller for longer.
Plant-based proteins are also rich in micronutrients like iron, magnesium, and B vitamins. They contain essential amino acids, though some sources may need to be combined to ensure a complete amino acid profile.
In addition to the health benefits, plant-based proteins also have a positive environmental impact. They have a significantly lower carbon footprint, use less water, and require less land compared to animal proteins. Adopting plant-based diets can also help preserve biodiversity by reducing the demand for animal agriculture, a major driver of deforestation and habitat loss.
Plant-based proteins come from a variety of sources, including legumes, grains, nuts, seeds, and vegetables. Examples include lentils, beans, chickpeas, almonds, chia seeds, hemp seeds, quinoa, amaranth, and buckwheat.
Plant-based proteins can support the growth and development of children and adolescents when consumed as part of a well-rounded diet. They can also help older adults combat muscle loss and maintain strength.

How to calculate your protein needs
The recommended daily allowance (RDA) for protein is 0.8 grams per kilogram of body weight. For a 140-pound person, this equates to 51 grams of protein per day. However, active individuals, especially those trying to build muscle mass, may require more protein. According to some sources, about 10% of an active adult's calories should come from protein.
To calculate your protein needs, you can use one of the following methods:
- Divide your weight in pounds by 2.2 and then multiply by 0.8. For instance, a 132-pound individual with a sedentary lifestyle would require 48 grams of protein daily (0.8 x 132/2.2).
- Divide your weight in pounds by 20 and multiply by seven. For example, an individual weighing 200 pounds would require 70 grams of protein daily.
- Multiply your weight in pounds by 0.36. So, an adult weighing 150 pounds would require approximately 54 grams of protein.
- Calculate based on your calorie intake. The National Academy of Medicine recommends that 10 to 35 percent of your daily calories come from protein. Given that one gram of protein provides four kilocalories, a person consuming 2,000 calories per day can derive 200 to 700 of those calories from protein.
It is important to note that these calculations provide general approximations and do not consider individual factors such as health goals, underlying health conditions, athletic activity level, age, and gender. Consulting a qualified dietitian is advisable to determine your specific protein requirements, especially if you have unique health considerations.
While protein is essential for overall health and building muscle mass, excessive protein intake can lead to potential issues such as dehydration, inadequate carbohydrate intake, excessive caloric intake, and a lack of dietary variety. Therefore, it is crucial to maintain a balanced diet that includes a variety of nutrient-dense foods beyond just protein.
