Protein, calories, and B vitamins can all be found in red meat in significant amounts. However, evidence indicates that eating red meat may potentially have negative health effects. A shorter lifespan is caused by detrimental effects such as the emergence of cancer and cardiovascular disease in persons who consume more red meat.
Nutrition and diet
In the twenty-first century, there has been discussion on the connection between red meat and other health issues. Red meat consumption has increased globally over the same period. Red meat is the most popular form of meat consumed by people in the United States.
Numerous studies have discovered negative consequences of red meat consumption on diabetes, cancer, and cardiovascular health.
Red meat and wellbeing
To better understand the potential negative effects of ingesting these foods, nutritional studies increasingly make a distinction between red meats that have not been processed (beef, hog, and lamb) and red meats that have (bacon, hot dogs, sausage, salami, and bologna).
Given the high protein and fat content of red meat, some people have theorized that saturated fat and cholesterol may have a role in the development of cardiovascular problems, especially when ingested in excess.
The dietary iron level of red meat is another explanation for why it has been linked to cardiovascular diseases. Higher incidences of myocardial infarction and fatal heart disease have been associated with dietary iron and heme iron from red meat. Other research focusing on the saturation of iron-carrying cells, ferritins, has challenged this, though.
Although several other types of cancer have also been connected to red meat eating, colorectal cancer is the primary type. Due to heme iron and iron overload, irons have been associated with possible cancer risks. These substances boost colonic cytotoxicity, colonic epithelial cell proliferation, and oxidative stress by encouraging the synthesis of N-nitroso compounds from nitrates.
Other substances found in red meat are also linked to an increased risk of cancer. Red meat contains carcinogenic substances, and boiling it at high heat also produces additional carcinogenic components. It is thought that N-nitroso compounds, polycyclic aromatic hydrocarbons, and heterocyclic amines can all enhance the risk of developing cancer.
Considering the data
Some studies that link eating red meat to health disorders have come under fire for the study populations they used, either because there was a sizable vegetarian population included in the study or because the researchers failed to distinguish between processed and unprocessed meat.
Depending on what is thought to be the root cause of the health problems connected to eating meat, it may be important to avoid making a distinction between red and processed meat. For instance, heme iron and saturated fats have been identified as potential causal agents, yet their concentrations are comparable in both red meat and processed meat. The amounts of salt and nitrite in processed meats are higher than those in red meat.
Despite these objections, there is still enough data to support the idea that eating red meat can raise your chance of developing cancer, cardiovascular disease, and overall mortality. In one long-term study (spanning 28 years and involving 121 000 people), the researchers calculated that replacing one serving of one food with another (such as fish, chicken, nuts, legumes, low-fat dairy, or whole grains) might reduce the risk of death by up to 19%.

The selection of the population cohort is a significant factor that is frequently brought up as a critique of extensive human research. The majority of the volunteers in the many nutritional research undertaken in the US are White.
In comparison to other groups, these people can be more or less susceptible to specific ailments or have distinct dietary and lifestyle preferences. As a result, estimates of red meat-related mortality may be either lower or greater in certain regions of the world or among non-White people.
While some studies have come under fire for concentrating on areas where vegetarianism is prevalent, the criticism is reciprocal. Numerous studies including large cohort populations have a propensity to favor levels of moderate or high meat consumption, neglecting the possibility of decreased hazards with levels of low or no meat eating.

Recent research has shown that even a low intake of red meat is linked to an increased risk of mortality and cardiovascular disease-related mortality when compared to a red meat-free diet.
