To assess the health benefits, let's make a relative comparison to white granulated sugar. Because the statement that rice syrup is healthy is already contradicted by looking at the sugar content.
Even if its glycemic index is similar to that of table sugar, which is simply due to the glucose, rice syrup has two advantages. On the one hand the lower calorific value (kcal/100 g) and on the other hand the plus in nutrients. Due to the lower intensity of sweetness, however, the tendency is more in the direction that we consume more of it.
What makes the brown rice syrup so special and popular in many eyes is the fructose-free carbohydrate spectrum. The glucose doesn't make it significantly healthier, but it definitely makes it easier to digest. Sugar remains sugar in this case - despite some advantages, the same applies to rice syrup: less is more.
