"Maple syrup is still made the same way it has been for decades: by boiling sap from maple trees. The syrup can then be dried, powdered, and sold as maple sugar.
While maple syrup does contain some vitamins, minerals, and antioxidants, the amounts in a typical serving are quite small. For example, one tablespoon provides about 1% of your daily needs for calcium, potassium, and iron.
However, it does pack a solid amount of magnesium – a mineral that helps produce collagen and promote skin and bone health – with 25% of your Daily Value.
When it comes to choosing a syrup, you might want to consider the color. Generally, syrup made earlier in the season tends to be lighter; while syrup produced at the end of the season, when sap flow slows, is darker. (That said, in some years, nearly all of a season’s crop may be light.) Dark syrups may have higher mineral and antioxidant levels.
Plus, darker syrups tend to have the strongest maple taste, which may help you use less. In fact, that’s another benefit of swapping white sugar for maple syrup: In recipes, you can use three-fourths as much. For example, if a recipe calls for a quarter cup of sugar (or four tablespoons), you can use three tablespoons of maple syrup instead.
Another trick I use is diluting syrup. I’ll swirl together a teaspoon each of maple syrup and water, add spices, like ginger and cinnamon; then drizzle it over foods like oatmeal, yams, baked fruit, or roasted carrots. You still get the distinct flavor and sweetness, but with just 4 grams of sugar and less than 20 calories."
