Butter nutrition, glycemic index, calories and serving size
Butter Glycemic index (GI)
Butter is made by separating the fat and protein content of milk. Because of this, butter is particularly low in carbohydrates, containing less than 0.01g of it. This makes it exceedingly difficult to consume enough butter to calculate its glycemic index. The glycemic index of butter is most likely very low, close to 0.
According to the International Tables of Glycemic Index Values, the glycemic index of white bread with butter is equal to 59 (1).
Consumption of fat, such as butter, with a high glycemic index food, such as bread, has been studied to lower the glycemic response of the meal (2).
Another study has shown butter intake to reduce the GI of bread from 88 to 67 (3).
Overall, butter has a very low glycemic index and might even reduce the glycemic response of a meal, however, it is important to note that butter is rich in saturated fatty acids. A diet high in saturated fats has been associated with an increased risk of type 2 diabetes (4).
