Eating just two slices of ham a day may increase the risk of developing diabetes by 15% within the next decade, according to a large study. Data from nearly two million people, analysed by a team led by the University of Cambridge, also revealed that consuming 100 grams of unprocessed red meat a day was associated with a 10% higher risk of diabetes. The findings, published in The Lancet Diabetes and Endocrinology, support recommendations to reduce meat intake. Professor Nita Forouhi, from the University of Cambridge, highlighted that limiting processed and red meat consumption could decrease type 2 diabetes cases. The NHS advises reducing red and processed meat intake from 90g to 70g per day.
For the study, researchers analysed data from 31 cohorts across 20 countries to understand the link between meat consumption and diabetes risk. Consuming 50 grams of processed meat daily was associated with a 15% higher risk of diabetes in the next 10 years. However, the impact of poultry consumption on diabetes risk remains uncertain and requires further investigation. The study, funded by the European Union, aimed to consider various factors influencing the association between meat consumption and diabetes, including lifestyle and health behaviours.
Professor Nick Wareham, a senior author on the study, highlighted that the research provided concrete evidence linking different types of meat consumption to type 2 diabetes. Although the study did not determine the exact mechanisms behind the increased risk, experts advised moderating meat intake in line with healthy eating guidelines. Dr. Duane Mellor, a dietitian, emphasised the importance of obtaining essential nutrients found in meat from other food sources when reducing consumption.
The study’s findings align with national healthy eating advice, which includes a diet rich in vegetables, fruit, nuts, seeds, beans, and limited amounts of meat, along with regular physical activity. The research underscored the importance of balanced nutrition to reduce the risk of developing type 2 diabetes. As the study sheds light on the impact of meat consumption on diabetes risk, experts recommend making informed dietary choices to support overall health and well-being.
