Protection against Diabetes and Heart Disease with this nut
We always knew nuts were good for health and the heart. But some nuts are better than others for specific diseases like diabetes and cardiovascular disease.
Lessening after-meal surges in blood sugar helps protect against diabetes and cardiovascular disease, most likely by lessening the increase in cholesterol-damaging free radicals that accompanies large elevations in blood sugar. This is one reason why low- glycemic index diets result in lower risk of diabetes and heart disease.
Almonds appear to not only decrease after-meal rises in blood sugar, but also provide antioxidants to mop up the smaller amounts of free radicals that still result. (Jenkins DJ, Kendall CW, Journal of Nutrition)
Researchers fed 15 healthy subjects 5 meals providing a comparable amount of carbohydrate, fat and protein: 3 test meals (almonds and bread, parboiled rice, and instant mashed potatoes) and 2 bread control meals. Each meal contained 50 grams of carbohydrate from white bread eaten either alone or in combination with 1, 2, or 3 ounces of almonds. To check subjects’ rise in blood sugar, blood samples were taken for glucose analysis immediately after eating, and at 15, 30, 45, 60, 90 and 120 minutes. Blood samples, taken before each meal and 4 hours afterwards, showed levels of protective antioxidants increased after the almond meal, but decreased after the other meals. And not only did the almond meal increase antioxidant levels, but unlike the other foods, almonds also lowered the rise in blood sugar and insulin seen after eating.
Eating almonds reduced the glycemic index (GI) of the meal and subjects’ rise in blood sugar in a dose-dependent manner—the more almonds consumed, the lower the meal’s GI and the less the rise in subjects’ blood sugar after eating.
