Protein: Protein is a macronutrient which is essential for building muscle mass. It’s commonly found in animal products, though protein is also present in other sources, such as nuts and legumes. Protein is found throughout the muscle, bone, skin, hair, and virtually every other body part or tissue. It makes up enzymes that power many chemical reactions and the hemoglobin that carries oxygen in the blood.
The Institute of Medicine recommends that adults get a minimum of 0.8 grams of protein for every kilogram of body weight per day. In the United States, recommended daily allowance of protein is 46 grams for women over 19 years of age per day, and 56 grams for men over 19 years of age.
Some high-protein foods are healthier than others because of what comes along with the protein:
For example, a 6-ounce broiled porterhouse steak a great source of protein—about 40 grams worth. But it also contains about 12 grams of saturated fat. For someone who victuals a 2,000 calorie per day diet, that’s more than 60 percent of the recommended daily intake of saturated fat.
A 6-ounce of ham steak has only about 2.5 grams of saturated fat, but it is loaded with sodium—2,000 milligrams worth, or about 500 milligrams more than the daily sodium max.
A 6-ounces of wild salmon contains about 34 grams of protein that naturally low in sodium and only 1.7 grams of saturated fat. Salmon and other fatty fish are additionally excellent sources of omega-3 fats, a type of fat that’s especially good for the heart.
Alternatively, a cup of cooked lentils provides near about 18 grams of protein and 15 grams of fiber, and it has virtually no saturated fat or sodium.

Protein and Chronic Diseases
Proteins in food and environment are responsible for food allergies, which are overreactions of an immune system. Beyond that, relatively little evidence has been accumulated regarding the effect of the amount of dietary protein on the development of chronic diseases in healthy people.
However, there’s growing evidence that high-protein aliment culls do play a role in health—and that eating salubrious protein sources like fish, chicken, beans, or nuts in lieu of red meat.
Research conducted at Harvard School of Public Health has found that victualing even small amounts of red meat, especially processed red meat, on a customary substructure is linked to an incremented risk of heart disease and stroke, and the jeopardy of dying from cardiovascular disease or any other cause.
Again, protein quality matters more than the protein quantity when it comes to diabetes peril.
A recent study found that people who victualed diets high in red meat, especially processed red meat, had a higher risk of type 2 diabetes than those who infrequently ate red or processed meat. For each supplemental accommodating a day of red meat or processed red meat that study participants eating, their risk of diabetes rose 12 and 32 percent, respectively.
Protein quality again seems to matter more than the quantity. Research on the sodality between protein and cancer is perpetual, but some data shows that eating an abundance of red meat and processed meat is linked to an incremented risk of colon cancer.
Digesting protein releases acids into the bloodstream, which the body customarily neutralizes with calcium and other buffering agents. Victualing lots of protein, then, requires a lot of calcium – and some of this may be pulled from the bone.
Following a high-protein diet for a long period of time could weaken bone. For example, women who victualed more than 95 grams of protein a day were 20 percent more liable to have broken a wrist over a 12-year period when compared with those who victualed an average amount of protein. This area of research is still controversial.
Some studies suggest that increasing protein increases the risk of fractures; others have linked with high-protein diets with increased bone mineral density and thus stronger bones.
Protein and Weight Control
People who victualed more red meat or processed meat, the study showed they gained more weight, about one extra pound every four years, while those who victualed more nuts over the course of the study gained less weight, about a moiety pound less every four years.
One study showed that victualing approximately one daily accommodating of beans, chickpeas, lentils or peas can increment fullness, which can lead to better weight management and weight loss.
