Maple syrup has a low glycemic index rating of 54.² In comparison, table sugar has a glycemic index of 65, and honey has a glycemic index of 58.² This difference shows that maple syrup will raise blood sugar levels slower than regular sugar and honey.

When choosing a natural sweetener, many wonder whether maple syrup is healthier than table sugar. While maple syrup and sugar contain carbohydrates and can raise blood sugar levels, maple syrup has a lower glycemic index than white sugar.  The lower glycemic index of maple syrup is due to fructose, which is absorbed more slowly by the body than glucose, the primary sugar in white sugar. 

​

While maple syrup may have a lower glycemic index than sugar, both should be consumed in moderation as part of a healthy diet. Choosing natural sweeteners like maple syrup over processed white sugar may offer additional nutritional benefits. However, it’s important to avoid consuming too much of any sweetener, especially if your goal is to lose weight.

While maple syrup is a natural sweetener with beneficial compounds like antioxidants and antibacterial properties, it is also high in sugar and calories. People living with certain medical conditions, like diabetes, should be mindful that maple syrup causes sudden spikes in blood sugar. 

​

Maple syrup can be good for you when consumed as part of a balanced diet. If you have concerns about high blood sugar, add sources of protein and dietary fat when you consume maple syrup. This will help to slow digestion and prevent blood sugar spikes.

Maple syrup allergies are rare. However, individuals allergic to birch tree pollen may experience cross-reactivity when consuming maple syrup. This reaction can cause symptoms such as itching and tingling in the mouth. If you have allergies to tree saps or pollen, it is highly recommended to use caution when consuming maple syrup.

​

Also, while extremely uncommon, some individuals may have an allergy to maple. Symptoms may include skin reactions, gastrointestinal distress, or respiratory issues.
