For example, proteins move molecules around in our bodies, build internal structures in our cells and break down toxins. Proteins are chains of molecules called amino acids.

These protein chains routinely break down and then new ones are built as replacements. The body can make some of your amino acid building blocks but not all of them. We can get those from food sources such as nuts, seeds, eggs, fish, poultry, lean meats and legumes such as dry beans or lentils.

Proteins are a major part of our muscles. The or so muscles we have account for most of the energy our bodies burn. As the amount of muscle we have increases through exercise, for example, the amount of calories we need to fuel those muscles increases.

The National Academy of Medicine recommends that adults get a minimum of 0. In an analysis conducted at Harvard among more than , men and women who were followed for up to 32 years, the percentage of calories from total protein intake was not related to overall mortality or to specific causes of death. Animal-based foods meat, poultry, fish, eggs, and dairy foods tend to be good sources of complete protein, while plant-based foods fruits, vegetables, grains, nuts, and seeds often lack one or more essential amino acid.

Those who abstain from eating animal-based foods can eat a variety of protein-containing plant foods each day in order to get all the amino acids needed to make new protein, and also choose to incorporate complete plant proteins like quinoa and chia seeds. The effects of protein deficiency and malnutrition range in severity from growth failure and loss of muscle mass to decreased immunity , weakening of the heart and respiratory system, and death.

In fact, many in the U. When we eat foods for protein, we also eat everything that comes alongside it: the different fats, fiber, sodium, and more. Research conducted at the Harvard Chan School of Public Health has found that eating even small amounts of red meatespecially processed red meaton a regular basis is linked to an increased risk of heart disease and stroke , and the risk of dying from cardiovascular disease or any other cause. One of the reasons why plant sources of protein are related to lower risk of cardiovascular disease compared to protein from red meat and dairy is because of the different types of fat in these protein packages.

Plant-based protein sources are more unsaturated, which lowers LDL cholesterolan established risk factor for heart disease. Also, plant sources contain no cholesterol. Other factors are likely to contribute to the lower risk, but this is a key factor.

Again, the source of protein matters more than protein quantity when it comes to diabetes risk. Eating more red meat predicts a higher risk of type 2 diabetes, while consuming nuts, legumes, and poultry is related to lower risk. When it comes to cancer, once again, the source of protein seems to matter more than quantity.

The same healthy protein foods that are good choices for disease prevention may also help with weight control. Though some studies show benefits of high-protein, low-carbohydrate diets in the short term such as the paleo diet , avoiding fruits and whole grains means missing out on healthful fiber, vitamins, minerals, and other phytonutrients. Protein is a key part of any diet. The average person needs about 7 grams of protein every day for every 20 pounds of body weight.

Heart disease Research conducted at the Harvard Chan School of Public Health has found that eating even small amounts of red meatespecially processed red meaton a regular basis is linked to an increased risk of heart disease and stroke , and the risk of dying from cardiovascular disease or any other cause. Cutting back on red meat could save lives: the researchers estimated that if all the men and women in the study had reduced their total red and processed red meat intake to less than half a serving a day, one in ten cardiovascular disease deaths would have been prevented.

In another study of 43, men that looked at both amount and sources of protein found that intake of total protein was minimally associated with heart disease risk, but intake of protein from red meat was associated with higher risk.

The researchers compared people who ate diets with red meat with people who ate more of other types of foods i.

Researchers found that when diets with red meat were compared with all other types of diets combined, there were no significant differences in total cholesterol, lipoproteins, or blood pressure, although diets higher in red meat did lead to higher triglyceride concentrations than the comparison diets. Further evidence of the heart benefits of eating healthy protein in place of carbohydrate comes from a randomized trial known as the Optimal Macronutrient Intake Trial for Heart Health OmniHeart.

A healthy diet that replaced some carbohydrate with healthy protein or healthy fat did a better job of lowering blood pressure and harmful low-density lipoprotein LDL cholesterol than a higher carbohydrate diet.

Though weight loss was similar on the two diets, study participants on the high protein diet saw improvements in blood lipids and blood pressure. For example, one study of Swedish women who ate low-carbohydrate, high-protein diets had higher rates of cardiovascular disease and death than those who ate lower-protein, higher-carbohydrate diets.

Diabetes Again, the source of protein matters more than protein quantity when it comes to diabetes risk. A study found that people who ate diets high in red meat, especially processed red meat, had a higher risk of type 2 diabetes than those who rarely ate red or processed meat.

In a study that tracked the health of over , men and women, researchers found that individuals who most frequently ate red meats and chicken cooked at high temperatures were 1.

There was also an increased risk of weight gain and developing obesity in the frequent users of high-temperature cooking methods, which may have contributed to the development of diabetes. Of note, this research demonstrated that cooking methods might contribute to diabetes risk beyond the effects of meat consumption alone. More evidence that the source of protein matters comes from a year study that looked at the relationship between low-carbohydrate diets and type 2 diabetes in women. Low-carbohydrate diets that were high in vegetable sources of fat and protein were associated with a lower risk of type 2 diabetes.

Cancer When it comes to cancer, once again, the source of protein seems to matter more than quantity. Conclusions were primarily based on the evidence for colorectal cancer.

Data also showed positive associations between processed meat consumption and stomach cancer , and between red meat consumption and pancreatic and prostate cancer.

Bone health Digesting protein releases acids into the bloodstream, which the body usually neutralizes with calcium and other buffering agents. As a result, early research theorized that eating lots of protein requires a lot more calcium which may be pulled from bone. Weight control The same healthy protein foods that are good choices for disease prevention may also help with weight control. Researchers at the Harvard Chan School of Public Health followed the diet and lifestyle habits of over , men and women for up to 20 years, looking at how small changes contributed to weight gain over time.

A subsequent detailed analysis of this cohort also found that eating red meat, chicken with skin, and regular cheese was associated with greater weight gain. Yogurt, peanut butter, walnuts and other nuts, chicken without skin, low-fat cheese, and seafood was associated with less weight gain.

Other considerations involving protein Specific proteins in food and the environment are involved in food allergies, which are overreactions of the immune system take gluten and celiac disease , for example. Medical journals are also full of reports linking allergic responses to specific protein sources with a variety of conditions breathing problems, chronic digestive issues, etc.

Eggs, fish, milk, peanuts, tree nuts, and soybeans cause allergic reactions in some people. In , the FDA announced a voluntary program to limit the routine use of antibiotics in food production such as giving antibiotics to healthy animals to help them grow faster.

Just as different foods can have differing impacts on human health, they also have differing impacts on the environment. Agriculture is a major contributor of greenhouse gas GHG emissions globally, the accumulation of which is driving climate change at a rate unprecedented in human history. However, not all foods have an equal impact. Production of animal-based foods tends to have higher GHG emissions than producing plant-based foodsand dairy and especially red meat particularly beef, lamb, and goat stand out for their disproportionate impact.
