Maple syrup is a sweet substance extracted from the sap of maple trees and has a similar taste to honey. It is a great choice as a sweetener because it contains several micronutrients such as calcium, magnesium, potassium... as well as antioxidants.
According to the United States Department of Agriculture (USDA), 100 grams of maple syrup provides 260 calories and 67% carbohydrates, with no significant protein or fat.
Additionally, maple syrup has a lower glycemic index than refined white sugar. Refined table sugar will cause your blood sugar to spike higher and faster than maple syrup.
However, maple syrup is also a sweetener. The American Heart Association recommends no more than 6 to 9 teaspoons of it per day; this should depend on your daily calorie intake and activity level.
It is important that any amount of sugar added to coffee is within your body's sugar limit throughout the day.
So, if you want your coffee sweeter, use maple syrup instead of regular sugar to give your body a small dose of nutrients.
Additionally, blood sugar levels also depend on whether you drink coffee with food and what type of food you eat.
