As a Canadian, maple syrup runs in my blood. There are a bunch of claims that maple syrup is a healthy, natural sweetener, but what exactly does that mean? Let’s science it.
First we can look at the nutrient contents of maple syrup compared to sucrose, or your typical refined white table sugar. For an equivalent serving size, maple syrup is lower in calories and sugar and contains some beneficial minerals like calcium, zinc and manganese. But the amounts are pretty low, and it is best to get these nutrients from whole foods.
There’s been a fair bit of research into some of the other antioxidant nutrients in maple syrup. These antioxidants aren’t essential for life, but they can help reduce oxidative stress in the body. Think of oxidative stress as rust - overtime, oxidative stress or rusting in the body contributes to the development of many chronic diseases like cardiovascular disease and diabetes, and accelerates the aging process. Diets that are high in antioxidant nutrients, like beta-carotene that makes carrots orange, reduces oxidative stress.
Chemical analysis has shown that maple syrup has a bunch of different antioxidant compounds in it. Test tube studies have shown that maple syrup decreases the reactions that lead to oxidative stress. It turns out there’s actually more of these antioxidants in the lower grades of maple syrup - these are the darker coloured syrups that are harvested later in the season.
So that seems like a good thing! Pour on the maple syrup, reduce my oxidative stress! But here’s the thing - you’d probably have to consume TONNES of maple syrup to actually get enough antioxidants to have any benefit. One serving of maple syrup has only a fraction of the antioxidant capacity of one serving of walnuts. So far maple syrup research has been in test tubes and cells in a dish, which is pretty different than a human! We have no idea how much of these beneficial nutrients we can absorb and where they would go in our body.
Plus, maple syrup is still mostly sugar. The Dietary Guidelines for Americans recommends consuming no more than 10% of your daily calories as added sugar. For a standard 2000kcal diet that would be 50g of table sugar, or the equivalent of a quarter cup of maple syrup.
Putting this all together, we can ask two questions. First, should you add maple syrup to your diet for health purposes? Nope, too much added sugar. Question two - is it healthier to replace white sugar with maple syrup? Maybe a little bit. Though it hasn’t really been studied, the current science suggests that the benefits would be marginal to non-existent at healthy levels of added sugar consumption. Although maple syrup contains some beneficial nutrients, they don’t offset the impacts of the sugar. There is some research going on with maple syrup extracts, that essentially isolate just the antioxidants remove the sugar, which seems like a more feasible approach to me.
So what do we do with this information? If you like the flavour of maple syrup, then use it in place of white sugar where applicable. Just make sure to stay under that added sugar max most of the time. Personally, I use maple syrup when I eat pancakes or bake a cake on special occasions, and every once in a while I’ll use a tiny bit when roasting veggies or in a delicious bourbon cocktail. But it doesn’t play a prominent role in my dietary pattern. That’s what science tastes like.
