Home Nutrition News What Should I Eat? What Is Protein? How Much Protein Do I Need? For a pound person, that means about 70 grams of protein each day. Table: Comparing protein packages. What about protein powders?

Powdered protein can come from a variety of sources, including eggs, milk e. Some protein powders contain protein from multiple sources; for instance, a vegan option might include protein derived from peas, pumpkin seeds, sunflower seeds, and alfalfa.

Like other dietary supplements, protein powders are not regulated by the U. Food and Drug Administration for safety. They can often contain non-protein ingredients, including vitamins and minerals, thickeners, added sugars, non-caloric sweeteners, and artificial flavoring.

If you choose to consume protein powder, it is important to read the nutrition and ingredient labels beforehand, as products may contain unexpected ingredients and large amounts of added sugars and calories.

Heart disease Research conducted at the Harvard Chan School of Public Health has found that eating even small amounts of red meat—especially processed red meat—on 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.

chicken, fish, carbohydrates, or plant proteins such as legumes, soy, or nuts , looking at blood concentrations of cholesterol, triglycerides, lipoproteins, and blood pressure—all risk factors for cardiovascular disease.

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. A study also found a link between high consumption of red meat during adolescence and premenopausal breast cancer, while higher intakes of poultry, nuts, and legumes were associated with lower risk.

High-temperature grilling creates potentially cancer-causing compounds in meat, including polycyclic aromatic hydrocarbons and heterocyclic amines.

Learn about tips for healthy grilling. After tracking their diets for up to 32 years, the authors found that a higher intake of red meat, especially processed versions sausage, bacon, hot dogs, salami , was linked to a modestly higher risk of death, while a higher protein intake from plant foods carried a lower risk.

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. New research highlight: Red meat and diabetes risk People who eat just two servings of red meat per week may have an increased risk of developing type 2 diabetes compared to people who eat fewer servings, and the risk increases with greater consumption, according to a new study led by researchers from Harvard T.

Chan School of Public Health. They also found that replacing red meat with healthy plant-based protein sources, such as nuts and legumes, or modest amounts of dairy foods, was associated with reduced risk of type 2 diabetes.

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 foods—and dairy and especially red meat particularly beef, lamb, and goat stand out for their disproportionate impact.

Prioritize hearty and savory plant-based preparations Simple strategies for creating filling, delicious, and even budget-friendly plant-based dishes.

Eat a little less red meat, any way you can Assess how often you eat red meat, and see if one of these strategies can help you find a way to cut back a bit. Consume less meat, enjoy more variety This approach boosts healthy plant-based foods like beans, nuts, whole grains, and other veggies, while still providing ways to incorporate some of your favorite animal-based foods.

A protein consists of amino acids AA linked by peptide bonds. Dietary protein is hydrolyzed by proteases and peptidases to generate AA, dipeptides, and tripeptides in the lumen of the gastrointestinal tract.

These digestion products are utilized by bacteria in the small intestine or absorbed into enterocytes. AA that are not degraded by the small intestine enter the portal vein for protein synthesis in skeletal muscle and other tissues.

AA are also used for cell-specific production of low-molecular-weight metabolites with enormous physiological importance. Thus, protein undernutrition results in stunting, anemia, physical weakness, edema, vascular dysfunction, and impaired immunity.

Based on short-term nitrogen balance studies, the Recommended Dietary Allowance of protein for a healthy adult with minimal physical activity is currently 0.

are consuming more than enough protein, especially from animal-based foods. 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 meat—especially processed red meat—on 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 cholesterol—an 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. Because protein is found in an abundance of foods, many people can easily meet this goal.

Building off this general guidance, here are some additional details and tips for shaping your diet with the best protein choices:. Looking to reduce red and processed meats, but unsure where to start? Here are a few approaches to cutting-back while keeping your meals satiating and flavorful.

You do not need to eat animal products to get all the protein you need in your diet. Essential amino acids cannot be made by the body, and must be supplied by food.

They do not need to be eaten at every meal. The balance over the whole day is more important. Nonessential amino acids are made by the body from essential amino acids or in the normal breakdown of proteins.

The amount of protein you need in your diet will depend on your overall calorie needs. One gram of protein supplies 4 calories. One ounce 30 grams of most protein-rich foods contains 7 grams of protein. An ounce 30 grams equals:. Children and teens may need different amounts, depending on their age.

Some healthy sources of animal protein include:. The US Department of Agriculture's newest food guide, called MyPlate , can help you make healthy eating choices. National Academy of Sciences, Institute of Medicine, Food and Nutrition Board.

Washington, DC, Updated Accessed April 21, Ramu A, Neild P. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.

Amino acids are joined together by peptides, which are broken by proteases. From your stomach, these smaller chains of amino acids move into your small intestine.

As this happens, your pancreas releases enzymes and a bicarbonate buffer that reduces the acidity of digested food. This reduction allows more enzymes to work on further breaking down amino acid chains into individual amino acids.

Protein absorption also happens in your small intestine , which contains microvilli. These are small, finger-like structures that increase the absorptive surface area of your small intestine. This allows for maximum absorption of amino acids and other nutrients.

The first step in increasing your protein absorption is choosing whole proteins that contain all nine essential amino acids. These include:. It was previously believed that vegetarian proteins must be consumed at the same meal in order for the body to form complete proteins.

So for vegetarians , variety is key. In addition to choosing the right protein sources, you can also adopt certain habits to help get the most out the food you eat. Protein is a vital nutrient for almost every part of your body.

You can maximize the nutrients you get from protein sources by eating complete proteins and adopting certain habits, such as chewing thoroughly before swallowing. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.
