A study published in The Physician and Sportsmedicine shows that raisins may positively affect glucose levels and systolic blood pressure among people with type 2 diabetes mellitus (T2DM).
This 12-week randomized study of 51 study participants evaluated the impact of routine consumption of dark raisins versus alternative processed snacks on glucose levels and other cardiovascular risk factors among patients with type T2DM.
The researchers found that those who consumed raisins had a 23% reduction in postprandial glucose levels. Compared to alternative snacks, those who consumed raisins had a significant 8.7 mmHg reduction in systolic blood pressure but did not experience a significant reduction in diastolic blood pressure.
However, it should be noted that those who consumed raisins did not have a significant improvement in body weight, body mass index, waist circumference, fasting insulin, homeostatic model assessment of insulin resistance, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL), triglyceride, or non-HDL cholesterol levels.
The researchers concluded that the data supports raisins as a healthy alternative compared to other snacks in patients with T2DM.
