Research published in The Lancet Diabetes & Endocrinology has uncovered links between red meat consumption and a risk of type 2 diabetes. This study was analyzed from the data of nearly 2 million participants across 20 countries.

The first study published in The Lancet Diabetes and Endocrinology involved meta-analysis of data from nearly two million adults across 31 studies conducted in 20 countries including the United States various European nations and parts of Asia.
Participants were monitored for an average of 10 years during which their diets and health outcomes were closely examined.
The research revealed that consuming just 1.8 ounces of processed meat daily such as a medium-sized sausage or two to three slices of bacon was associated with a 15% increase in the risk of developing Type 2 diabetes.
Similarly a daily intake of 3.5 ounces of unprocessed red meat, equivalent to a small steak was linked to a 10% increased risk.
The data also suggested that eating poultry might be associated with an 8% increased risk of Type 2 diabetes.
This finding was less consistent and was only significant in European populations indicating the need for further research. Regular consumption of processed meats such as ham, sausages and bacon, is strongly associated with a higher risk of developing type 2 diabetes.
Specifically consuming 50 grams of processed meat per day is linked to a 15% increased risk of type 2 diabetes over a decade.
Eating 100 grams of unprocessed red meat daily is associated with a 10% higher risk of type 2 diabetes.
The study also examined poultry consumption, finding that eating 100 grams of poultry daily is associated with an 8% increased risk of type 2 diabetes.
Red meat and processed meats are typically high in saturated fats, which have been associated with increased insulin resistance.
People who consume large amounts of meat may also have diets that are low in fruits, vegetables and other healthful foods, which are essential for maintaining a healthy body weight and reducing diabetes risk.
The method of cooking meat at high temperatures through frying or grilling can lead to the formation of harmful compounds that cause cell damage, inflammation and further insulin resistance.
A critical factor highlighted in the studies is the role of heme iron, a type of iron found in red meat. High levels of heme iron intake were linked to a 26% increased risk of developing Type 2 diabetes.
Heme iron may contribute to the disease by increasing inflammation and damaging the pancreas, which is critical for insulin production.

Processed meats include products like bacon, sausages and deli meats, showed a stronger and more consistent association with increased diabetes risk than unprocessed meats.
This difference may be due to the presence of preservatives, high sodium content and other additives in processed meats.
Experts recommend minimizing the consumption of processed meats as much as possible, viewing them as occasional indulgences rather than dietary staples.
The consumption of red meat and processed meats has been linked to a higher risk of heart disease, certain types of cancer and premature death.
With over 400 million people globally diagnosed with Type 2 diabetes, a condition that is a leading cause of complications such as blindness, kidney failure, heart attacks, strokes and limb amputations.
While it is not necessary to eliminate red meat entirely from the diet, experts suggest that moderation is key. Consuming one or two servings of red meat per week is likely to be safe for most individuals.
A shift from a meat-centric diet to one rich in plant-based foods such as whole grains, fruits, vegetables, legumes, nuts and seeds is strongly recommended.
These foods have been associated with a lower risk of Type 2 diabetes and other chronic diseases. The studies suggest that even small reductions in meat consumption can have an huge impact on health outcomes.
Reducing daily intake of red meat by just 20 grams could lower the risk of diabetes.
The intake of saturated fats and harmful compounds formed during high-temperature cooking are primary contributors to increased insulin resistance, which is a precursor to Type 2 diabetes.
Heme iron in red meat has been shown to trigger inflammatory responses that can damage cells in the pancreas leading to impaired insulin production and an increased risk of diabetes.
Processed meats contain nitrates and nitrites, which can contribute to oxidative stress and cellular damage.
Health experts advocate for a diet high in vegetables, fruits, nuts and legumes, which may provide protective benefits against type 2 diabetes.
Replacing red meat and processed meats with healthier alternatives like poultry or plant-based proteins is recommended.
