More Meat May Raise Diabetes Risk

Previously, a number of studies have suggested that red meat consumption associates with an increased risk of type-2 diabetes.  An Pan, from the Harvard School of Public Health (Massachusetts, USA), and colleagues explored whether changes in red meat intake affect subsequent diabetes risk.  The study included follow-up on 26,357 men enrolled in the Health Professionals Follow-Up study, 48,709 women enrolled in the Nurses' Health Study, and 74,077 women enrolled in the Nurses' Health Study II who reported their diet, including meat derived from mammals, on a food frequency questionnaire every 4 years. The researchers found that self-reported type 2 diabetes incidence was almost doubled for individuals who moved from low intake of two servings per week up to high intake of seven or more servings per week versus those who stayed at a low level over the 4 years from baseline.   Further, moving from a moderate two-to-six servings per week up to high intake boosted risk 87%; whereas shifting from moderate to low intake of red meat lowered risk by 19%.  Staying at a moderate intake was associated with 37% higher diabetes onset risk than staying at a low intake.  Staying at a high intake was 2.10-times more risky for incident diabetes than staying at a low intake. Cutting red meat consumption to a moderate level had a benefit.   The study authors conclude that: "Our results add further evidence that limiting red meat consumption over time confers benefits for [type-2 diabetes] prevention."

Body Mass Index (BMI) is the ratio between height and weight. The number indicates whether a person is underweight, overweight, or within a normal weight range. Individuals with a BMI of 25.0 or greater are considered overweight and those with a BMI of 30.0 or greater are considered obese. Increased BMI is an established risk factor for several causes of death including ischemic heart disease, stroke, and certain cancers.

Researchers from the University of Oxford (United Kingdom) reported that a BMI above the normal range is associated with an increased risk of death. The team reviewed data from 57 prospective studies involving a total of 894,576 patients in western Europe and North America as part of the Prospective Studies Collaboration. Mortality was about 30% higher for each additional 5 kg/m2, and primarily was correlated to 40% increased risk for vascular disease and 60 to 120% raised risks for diabetic, renal, and hepatic diseases, as well as 10% increased risk of neoplastic death and a 20% increased risk of death from respiratory causes. The researchers explain that: “"By avoiding a further increase from 28 kg/m2 to 32 kg/m2, a typical person in early middle age would gain about two years of life expectancy. Alternatively, by avoiding an increase from 24 kg/m2 to 32 kg/m2, a young adult would on average gain about three extra years of life."
