- About 90-95% of all diagnosed cases of diabetes are type 2, according to the Centers for Disease Control and Prevention.
- A new meta-analysis links low-fat dairy products to a reduced risk of T2D.
- The study linked red and processed meats to a greater T2D risk with finding suitable protein substitutes in fish and eggs.
- Other experts have said that T2D may be a condition that is reversible through diet and lifestyle interventions.
According to the Centers for Disease Control and Prevention (CDC), it is estimated that
Type 2 diabetes (T2D), the most common form of diabetes, develops when the body becomes resistant to the insulin produced by the pancreas or when the pancreas does not produce enough insulin. Insulin is a hormone that regulates blood sugar levels.
Diabetes can increase the risk of health complications, including cardiovascular disease, kidney failure, stroke, blindness, and circulatory problems, which may necessitate amputation of a toe, foot, or part of a leg.
In a new study, researchers in University of Naples Federico II In Naples, Italy, I collected evidence proving that certain foods can reduce the risk of developing T2D.
Annalisa GiosuèPh.D., of the institution’s Department of Clinical Medicine, led an extensive investigation exploring the relationship between different animal-based foods and the condition.
Giosuè presented her team’s findings at the annual meeting of European Association for the Study of Diabetes (EASD) conference in September.
However, research suggests that some animal products may offer health benefits to reduce the risk of T2D.
Type 2 diabetes is one of the leading causes of diet-related death worldwide. Learning more about how different food components increase or decrease the risk of type 2 diabetes is key to preventing it, said Dr. Jiusui. Medical news today.
To this end, Giosuè and colleagues examined 13 existing meta-analyses that examined which foods were associated with an increased risk of T2D.
They said this type of “review of reviews” brings together one of the most comprehensive levels of evidence possible in medical research.
Thirteen meta-analyses provided estimates of how 12 different types of animal foods may raise or lower the risk of T2D. Categories included:
- total meat
- red meat
- white meat
- Processed meat
- total dairy
- Full-fat dairy products
- Low fat dairy product
Daily consumption of 100 grams (3.53 ounces) of total meat was associated with a 20% increased risk. The same amount of red meat was associated with a 22% increased risk.
Half that amount of processed meats, such as deli meats, bacon and sausage, may have contributed to a 30% increase in risk of developing rheumatoid arthritis.
MNT Dr. Gyusuy asked why red and processed meat affects how the body processes blood sugar:
Meat, especially red and processed meat, is an important source of saturated fatty acids and cholesterol. [glycation end] products and heme [animal-derived] Iron, known for its ability to stimulate chronic subclinical inflammation and impair insulin sensitivity—the ability of cells to respond properly to insulin stimulation by absorbing glucose from the blood, thereby lowering blood glucose levels.”
Giosuè further explained that the sodium, nitrate, and nitrite in processed meat may “not only damage the insulin-producing cells of the pancreas but also cause oxidative stress and vascular disruption, which in turn, [reduce] Cell sensitivity to insulin”.
On the other hand, 50 grams (1.76 ounces) of white meat, which includes chicken and turkey, corresponds to only a 4% risk of T2D.
Dr. Jiusui said she believes this is because this meat has less fat, a healthier fatty acid content, and less animal-derived iron.
Dr. Giosuè and her team found that dairy products may or may not provide protection against T2D.
Consuming 200 grams (about one cup) of milk was associated with a 10% reduced risk of T2D, and 100 grams (3.52 ounces) of milk was associated with a 6% reduced risk.
A cup of whole milk and low-fat dairy products was associated with a 5% and 3% lower risk of T2D, respectively.
However, meta-analyses showed that cheese and full-fat dairy products had no effect on T2D risk. The quality of the evidence was low to moderate.
During the interview with MNTDr. Josoy mentioned several benefits of eating dairy products regularly:
Nutritionally, dairy products are a source of nutrients, vitamins, and other components (such as calcium, proteins, peptides, etc.) with potentially beneficial effects on glucose metabolism. For example, the whey protein in milk has a known effect on modulating elevated blood glucose levels after meals, as well as on appetite control and body weight. “
Protective effects in relation to increased body weight and obesity – drivers of type 2 diabetes development – have [also] Probiotics, which can be found in yogurt, another dairy ingredient whose consumption has been linked to a reduced risk of type 2 diabetes,”
Other low-quality evidence indicated that neither 100-gram servings of fish nor one egg per day significantly affected T2D risk.
The current study adds credence to the fact that limiting or avoiding consumption of animal foods, such as red and processed meat, can help prevent T2D.
“Our findings regarding the most appropriate intake of animal foods for the prevention of type 2 diabetes are largely consistent with the features of the Mediterranean diet, a vegetarian dietary pattern that has consistently demonstrated over time the potential to reduce diabetes risk. Type 2 diabetes and cardiovascular disease.”

Dr. Roy Taylora physician, author, professor and director of the Newcastle Magnetic Resonance Center at Newcastle University in the United Kingdom, was not involved in the current study, September 2022 podcast The widespread availability of “cheaper” and more accessible processed foods is driving the rise in cases of T2D.
He was particularly concerned about the increase in cases among children.
T2D is considered a chronic condition, although there is evidence to suggest that it can be reversed through diet and lifestyle modifications, according to American Diabetes Association.
Many studies, including
While more research is needed to determine whether a predominantly vegetarian diet, such as the Mediterranean diet, can reverse T2D, A growing body of evidence He explains that a Mediterranean-style diet may help prevent or delay the development of the condition.
The Italian researchers acknowledged that the 13 meta-analyses contained poor data in some cases. Thus, they are reluctant to make ‘strong recommendations’ for T2D prevention based on their study at this time.
However, Dr. Jiusui commented:
“Our study provides further support for the belief that a vegetarian diet, including limited intake of meat, moderate intake of fish, eggs and full-fat dairy products and habitual consumption of yoghurt, milk or low-fat dairy products, may represent the most feasible, sustainable and successful population strategy Certainly to improve type 2 diabetes prevention.”
