Poor diets contribute to global diabetes epidemic • Earth.com

Sub Levels

In a groundbreaking study, researchers at Tufts University’s Friedman School of Nutritional Sciences and Policy found that a staggering 70% of people with type 2 diabetes worldwide may be linked to a poor diet. I found This number is significantly higher than the 40% estimated in previous studies. Experts say the difference may be due to the inclusion of new information in the analysis and the inclusion of more recent data on dietary habits.

One of the main drivers of the higher rates of type 2 diabetes associated with poor diets is the inclusion of refined grains in the analysis for the first time. Refined grains such as white rice and wheat have been identified as one of the largest contributors to the global diabetes burden.

Additionally, the updated data in this study were based on national, individual-level dietary surveys rather than agricultural estimates, which may have provided a more accurate assessment of people’s eating habits.

Overall, experts found that an inadequate diet could be the cause of more than 14.1 million cases of type 2 diabetes worldwide in 2018. However, the researchers are aware of the uncertainties surrounding these new estimates and note that they may be refined further as new data become available.

Despite uncertainties, this study provides valuable insight into the impact of dietary factors on the global prevalence of type 2 diabetes and the need for targeted interventions to address these factors. emphasizes sexuality. The study is published in a journal natural medicine.

Why Research Matters

As the global incidence of type 2 diabetes continues to rise, these findings have important implications for public health policy, health professionals, and the private sector. By identifying important dietary contributors, such as refined grains, stakeholders can develop strategies and initiatives to promote healthier dietary choices and, ultimately, Help limit the devastating impact of type 2 diabetes on individuals, families and healthcare systems.

As scientific understanding of the relationship between diet and type 2 diabetes advances and new data emerge, it will be important for researchers to continue to refine these estimates. In doing so, it will help inform future efforts to address the growing burden of type 2 diabetes.

“Our study suggests that poor carbohydrate quality is the leading cause of diet-related type 2 diabetes globally, with significant variation across countries and over time.” ‘s new findings highlight key areas for national and global attention to improve nutrition and reduce the devastating burden of diabetes.”

How to proceed with research

To develop their model, the researchers used data from the global dietary database, demographics from a variety of sources, estimates of global type 2 diabetes incidence, and data from multiple published papers. We utilized information about how food choices affect individuals with obesity and type 2 diabetes.

Analyzes show that, at a global level, poor diets are associated with higher rates of type 2 diabetes among men compared with women, young adults compared with older adults, urban residents compared with rural residents, and overall type 2 diabetes mellitus. It became clear that it contributed to a large proportion of the incidence rate.

Regionally, Central and Eastern Europe and Central Asia, especially Poland and Russia, have the highest number of diet-related type 2 diabetes cases. This may be due to a diet rich in red meat, processed meat and potatoes. Latin America and the Caribbean, particularly Colombia and Mexico, have had high rates of diet-related type 2 diabetes due to sugary drinks, processed meat consumption, and low intake of whole grains.

In contrast, in South Asia and sub-Saharan Africa, the effect of diet on people with type 2 diabetes was low. However, sub-Saharan Africa saw the greatest increase in his type 2 diabetes cases between 1990 and 2018 due to poor diet. Among the 30 populous countries surveyed, India, Nigeria and Ethiopia have the fewest cases of her type 2 diabetes associated with unhealthy diets. .

Megan O’Hearn, lead author of the study, who conducted the study as a PhD candidate at the Friedman School, warns: Build capacity and promote health inequalities around the world. She said these findings should help clinicians, policy makers, and private sector stakeholders to prioritize nutritional priorities as they encourage healthier dietary choices to combat the pandemic. We emphasized that it may be useful to inform

What is type 2 diabetes?

Type 2 diabetes is a chronic metabolic condition that affects how the body processes glucose (sugar), its primary source of energy. It is the most common form of diabetes, accounting for about 90-95% of all diabetes cases. This condition is characterized by insulin resistance, in which the body’s cells do not respond properly to insulin. Insulin is a hormone produced by the pancreas that allows cells to take up glucose from the bloodstream.

Risk Factors for Type 2 Diabetes


The risk of developing type 2 diabetes increases with age, especially after age 45. However, due to factors such as obesity and a sedentary lifestyle, the condition is increasingly being diagnosed in young individuals, including children and adolescents.

family history

Having a close relative, such as a parent or sibling, with type 2 diabetes puts you at an increased risk of developing type 2 diabetes.


Being overweight or obese is one of the most important risk factors for type 2 diabetes, as excess fat can lead to insulin resistance.

Lack of exercise

A sedentary lifestyle increases the risk of type 2 diabetes because regular physical activity helps maintain a healthy weight and regulate blood sugar levels.


Certain ethnic groups, including African Americans, Hispanics, Native Americans, Asian Americans, and Pacific Islanders, are at increased risk of developing type 2 diabetes compared to non-Hispanic whites. increase.

gestational diabetes

Women who have gestational diabetes during pregnancy are at increased risk of developing type 2 diabetes later in life.

Symptoms, Management and Prevention

Symptoms of type 2 diabetes include increased thirst, frequent urination, unexplained weight loss, fatigue, blurred vision, slow-healing wounds, and frequent infections. However, some people with type 2 diabetes may have no symptoms, which makes regular testing and screening important for early detection and management.

Management of type 2 diabetes usually requires a combination of lifestyle changes, such as maintaining a healthy diet, engaging in regular physical activity, and losing excess weight. In some cases, oral medications or insulin injections may be needed to control blood sugar levels.

Type 2 diabetes prevention strategies include adopting a healthy, balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Engage in regular physical activity; maintain a healthy weight; and avoid tobacco products. Regular testing and screening can also help detect early signs of type 2 diabetes and facilitate prompt intervention to prevent or delay the onset of the condition.
