This Is How Much Protein You Really Need to Eat in a Day

Proteins are large molecules that our cells need to function properly. They consist of amino acids. The structure and function of our bodies depend on proteins. Muscles, skin, bones, and other parts of the human body contain significant amounts of protein, including enzymes, hormones, and antibodies.

Proteins also work as neurotransmitters. Hemoglobin, a carrier of oxygen in the blood, is a protein. Proteins are long chains of amino acids that form the basis of all life.

They are like machines that make all living things, whether viruses, bacteria, butterflies, jellyfish, plants, or human function. The human body consists of around trillion cells. Each cell has thousands of different proteins. Together, these cause each cell to do its job. The proteins are like tiny machines inside the cell. Protein consists of amino acids, and amino acids are the building blocks of protein. There are around 20 amino acids.

These 20 amino acids can be arranged in millions of different ways to create millions of different proteins, each with a specific function in the body. The structures differ according to the sequence in which the amino acids combine. The 20 different amino acids that the body uses to synthesize proteins are: Alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine.

Amino acids are organic molecules that consist of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. It is the amino acids that synthesize proteins and other important compounds in the human body, such as creatine, peptide hormones, and some neurotransmitters. We sometimes hear that there are three types of protein foods:. Complete proteins : These foods contain all the essential amino acids.

They mostly occur in animal foods, such as meat, dairy, and eggs. Incomplete proteins : These foods contain at least one essential amino acid, so there is a lack of balance in the proteins. Plant foods, such as peas, beans, and grains mostly contain incomplete protein.

Complementary proteins : These refer to two or more foods containing incomplete proteins that people can combine to supply complete protein. Examples include rice and beans or bread with peanut butter. The main functions of proteins in the body are to build, strengthen and repair or replace things, such as tissue. They can be :. Keratin is a structural protein that strengthens protective coverings, such as hair.

Collagen and elastin, too, have a structural function, and they also provide support for connective tissue. Most enzymes are proteins and are catalysts, which means they speed up chemical reactions. They are necessary for respiration in human cells, for example, or photosynthesis in plants. Protein is one of the essential nutrients, or macronutrients, in the human diet, but not all the protein we eat converts into proteins in our body. When people eat foods that contain amino acids, these amino acids make it possible for the body to create, or synthesize, proteins.

If we do not consume some amino acids, we will not synthesize enough proteins for our bodies to function correctly. There are also nine essential amino acids that the human body does not synthesize, so they must come from the diet. All food proteins contain some of each amino acid, but in different proportions. Gelatin is special in that it contains a high proportion of some amino acids but not the whole range. The nine essential acids that the human body does not synthesize are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Foods that contain these nine essential acids in roughly equal proportions are called complete proteins. Complete proteins mainly come from animal sources, such as milk, meat, and eggs.

Soy and quinoa are vegetable sources of complete protein. Combining red beans or lentils with wholegrain rice or peanut butter with wholemeal bread also provides complete protein. The body does not need all the essential amino acids at each meal, because it can utilize amino acids from recent meals to form complete proteins.

If you have enough protein throughout the day, there is no risk of a deficiency. Protein deficiency due to a low intake of protein in the diet is unusual as an isolated condition in the U.

For children, it is 10 to 30 percent. Worldwide, however, a lack of protein in the diet is a matter of concern, especially when it affects children. It can lead to problems of malnutrition , such as kwashiorkor and marasmus.

These can be life-threatening. Very low protein intake can lead to :. The FDA recommend that adults consume 50 grams of protein a day, as part of a 2,calorie diet.

However, specifying exact amounts is difficult, because a range of factors , such as age, gender, activity level, and status, for example, pregnancy, play a role. Other variables include the proportion of amino acids available in specific protein foods and the digestibility of individual amino acids. It also remains unclear how protein metabolism affects the need for protein intake.

According to the U. S Department of Agriculture USDA , the following foods will provide about 1 ounce of protein per serving listed below:. The USDA recommend consuming between 5 and 7 ounces of protein foods a day for most people over the age of 9 years. They provide a calculator to make it easy to find out how much protein and other nutrients a person needs.

Protein provides calories. One gram of protein contains 4 calories. One gram of fat has 9 calories. The average American consumes around 16 percent of their calories from protein, whether of animal or plant origin.

Results of a review published in suggest that following a particular type of high-protein diet may encourage weight loss, but more work is needed to establish how to implement such a diet effectively. Adding protein to an existing diet is unlikely to lead to weight loss, but replacing fat and sugar with protein might help.

Replacing high-fiber foods — such as fruit, vegetables, and whole grains — with protein foods could have a negative effect. People should consider their overall consumption and dietary habits when making this kind of change, and speak to a doctor before going ahead.

Eating more protein may boost muscle strength and encourage a lean, fat-burning physique. Athletes and bodybuilders need to ensure they have enough protein to build and repair muscle, and this may be more than the minimum amount. A wide range of protein supplements is currently available, many claiming to encourage weight loss and increase muscle mass and strength. There is some evidence that too much protein may increase the risk of osteoporosis or kidney problems.

One study has indicated that whey protein may affect glucose metabolism and muscle protein synthesis. Other research concludes that at least one type of whey supplement can reduce body fat and preserve lean muscle when used in a reduced-calorie diet. According to the University of Michigan UOM , one investigation has found that whey protein enhanced performance in cyclists, and while another has suggested that it may lead to bone loss and osteoporosis, although this may also be due to other factors.

The UOM note that anyone using whey protein should not consume more than 1. In addition, as supplements, whey protein and similar products do not have FDA approval. This means is little or no control over their contents. Anyone who is considering taking protein supplements for fitness purposes should speak to a doctor who specializes in sports medicine.
