Potatoes fall in the high GI category. A cup of them can affect your blood sugar in the same way a can of soda would. One study found that women who ate a large amount of potatoes raised their risk of diabetes. Replacing them with whole grains cut their risk.
What is the glycemic load of potatoes?
In general, a standard portion of potatoes has a medium GL (GL~ 17.8) [10]. Foods with a high GI/GL will induce a rapid and high transient increase in the postprandial glucose concentration, while foods with a low GI/GL will induce a lower blood glucose response [11,15].
Which potatoes have the lowest glycemic load?
Boiled and roasted potatoes have the lowest GI (both 59), while baked potatoes are higher (69) and mashed and instant potatoes have the highest GI (78 and 82, respectively).
Do potatoes raise your blood sugar?
Like any other carb-containing food, potatoes increase blood sugar levels. When you eat them, your body breaks down the carbs into simple sugars that move into your bloodstream. This is what's often called a spike in blood sugar levels ( 1 ).
Are potatoes high glycemic or low glycemic?
Potatoes by themselves have a high Glycemic Index (GI). High glycemic index foods are a concern because they are digested quickly causing spikes in blood insulin levels, which increases the risk of diabetes and heart disease.
