Study Says Eating Red Meat Ups Diabetes Risk

Individuals who consume a diet high in red meat have a 19% increased risk of developing type 2 diabetes, while people who eat high amounts of processed red meat have a 51% increased risk, according to a new study published in the American Journal of Clinical Nutrition. The study also found substituting one serving of low-fat dairy, nuts or whole grains significantly lowered the risk.

The study found substituting red meat with nuts was associated with a 21% lower risk of type 2 diabetes; substituting low-fat dairy reduced the risk by 17%; and substituting whole grains lowered the risk by 23%.

Researchers at Harvard School of Public Health (HSPH) analyzed data from 37,083 men in the Health Professionals Follow-Up Study (1986-2006); 79,570 women in the Nurses' Health Study I (1980-2008); and 87,504 women in the Nurses' Health Study II (1991-2005). They also conducted an updated literature review analysis including data from the new study and previous studies that included 442,101 participants, 28,228 of whom developed type 2 diabetes during the study.

After adjusting for age, body mass index (BMI), and other lifestyle and dietary risk factors, they found a daily 100-gram serving of unprocessed red meat was associated with a 19% increased risk of type 2 diabetes; one daily serving of 50 grams of processed meats was associated with a 51% increased risk.

The researchers found that, for an individual who eats one daily serving of red meat, substituting one serving of nuts per day was associated with a 21% lower risk of type 2 diabetes; substituting low-fat dairy, a 17% lower risk; and substituting whole grains, a 23% lower risk.
