Eating nuts improves blood sugar control and cholesterol levels in type 2 diabetics, according to a research report in Diabetes Care.
Canadian researchers randomized 117 type 2 diabetics to eat their usual types of food, but also to be sure to eat either
- mixed nuts (about 2 ounces a day)
- muffins (I figure one a day)
- or half portions of each.
They did this daily for three months. Compared to the muffin group, the full nut group ate quite a bit more monounsaturated fatty acids. (I don’t have full study details because I have access only to the article abstract.)
Hemoglobin A1c, a reliable measure of blood sugar control, fell by 0.21% in the mixed nut group. That’s a move in the right direction. LDL cholesterol, the “bad cholesterol” linked to heart and vascular disease, also dropped significantly.
The investigators suggest that replacement of certain carbohydrates with 2 ounces of daily mixed nuts is good for people with type 2 diabetes.
