Red Meat Consumption Tied to Elevated Type 2 Diabetes Risk, Says Lancet Study

Consuming red meat has been linked to a higher risk of type 2 diabetes, according to an analysis involving over 19 lakh adults from 20 countries, including Southeast Asia. This study, published in The Lancet Diabetes and Endocrinology journal, provides the most comprehensive evidence to date.

The analysis revealed that habitual consumption of specific meats and their daily amounts - 50 grams of processed meat, 100 grams of unprocessed red meat, and 100 grams of poultry - increased the risk of developing type 2 diabetes by 15 per cent, 10 per cent, and eight per cent respectively.

Global Research Findings

An international team of researchers from the US, UK, Brazil, Mexico, and other countries noted that meat intake often exceeds recommended levels globally. This excessive consumption has been associated with non-communicable diseases like type 2 diabetes. However, most existing evidence is based on studies from high-income countries in North America and Europe.

The study included data from 31 cohorts within the InterConnect project. This data was compiled from scientific studies and online registries, including unpublished information. Among the total 19,66,444 participants, over one lakh developed type 2 diabetes during a follow-up period typically lasting ten years.

Regional Variations in Diabetes Risk

The positive associations between unprocessed red meat and processed meat with incident type 2 diabetes were significant across different regions. In the Americas, the risk increased by 13 per cent for unprocessed red meat and 17 per cent for processed meat. In Europe, these figures were six per cent and 13 per cent respectively. In the Western Pacific region and East Asia, the increases were 17 per cent and 15 per cent respectively.

The researchers also found that replacing 50 grams of daily processed meat intake with 100 grams of unprocessed red meat reduced the risk of type 2 diabetes by seven per cent on average. Additionally, substituting 50 grams of processed meat with 100 grams of poultry daily decreased diabetes risk by ten per cent.

Impact of Meat Substitution

However, the study found no evidence that replacing unprocessed red meat with poultry helped in reducing diabetes risk. The findings highlight the importance of dietary choices in managing health risks associated with meat consumption.

This extensive research underscores the need for balanced dietary recommendations worldwide to mitigate the risk of type 2 diabetes linked to meat consumption.
