Throughout history, people have eaten protein in different quantities. This has varied according to culture, tradition, and geography. In some cultures, under-consuming protein is common, whereas in industrialized countries, over-consumption is more common. Certain populations, like growing children and pregnant women, have higher protein 단백질보충제
Recommendations
In 2012, the NDA panel updated its protein intake recommendations, which used data on nitrogen balance to determine an appropriate target for protein intake in adults. That target is equivalent to about 1.1 grams of protein per kilogram of body weight. For children, the appropriate protein intake range is 0.7 to 0.9 g per day; for older people, the recommended amount is 0.8 to 1.5 g per kilogram of body weight.
Protein is one of the most essential nutrients for human health. In fact, several countries have established protein intake recommendations to promote adequate growth and development.
Sources
In a recent study, sources of protein intake were not associated with cardiovascular disease mortality. While higher amounts of animal protein were associated with greater risks, plant protein intake was not associated with increased CVD risk. The majority of the protein we eat comes from plant sources, such as beans and nuts. The main sources of animal protein are meat, poultry, and dairy products.
There are no fixed recommendations for protein intake, though a study by Harvard University looked at 130,000 people over 32 years and found that sources of protein intake mattered more than total protein intake.
Calculator
Protein intake is an important part of any diet and a protein intake calculator is a helpful tool to use in calculating your daily protein requirement. A protein calculator is designed to estimate how much protein your body needs, and is not a replacement for medical advice. Use it to figure out how much protein you should eat for a healthy body and fit mind.
This calculator works by using formulas to calculate the amount of protein your body needs each day. It first calculates your basal metabolic rate, the number of calories your body needs while at rest. The calculator will also take into account your age, gender, height, and weight. The calculator will then display the recommended daily allowance of protein for you based on your age, gender, height, and weight.
Effects on digestive system
In the human digestive system, protein is broken down by enzymes and undergoes many physical and chemical changes during digestion. These changes include peristaltic movement and changes in pH. Different types of protein have different susceptibilities to enzymes and are digested differently in different compartments of the digestive system. In addition, the particle size and conformation of the protein also play an important role in the digestion process.
Proteins are broken down into amino acids, and the body needs enough amino acids to function properly. Fortunately, amino acids are plentiful in many plant foods as well as animal sources. Plant sources of protein include soy, beans, legumes, nuts and grains. Some of these amino acids are essential, meaning that our body cannot produce them on its own. While it’s important to consume adequate amounts of protein every day, we don’t need to get all of these amino acids at once. We should try to get a balanced mix of amino acids from various sources.
Safety of protein supplements
While there is a large amount of research showing that protein supplements can increase your daily protein intake, there is no definitive evidence to support their safety. There are some side effects to watch for, however. Some supplements can increase bowel movements or cause bloating, flatulence, or diarrhea. In addition, too much protein can worsen kidney conditions or lead to increased osteoporosis. Other side effects include constipation, increased bowel movements, decreased appetite, and fatigue.
Unfortunately, the vast majority of consumers and doctors are unaware of the safety of protein supplements. Many products contain unnatural ingredients and may even be dangerous for teens. Some protein supplements contain prohibited substances and fillers. These fillers increase the volume of a supplement and are often added without the manufacturer’s knowledge. Additionally, some supplements are contaminated with steroids.
