Q. The label says 2 tablespoons of Skippy peanut butter has 3 grams of added sugar. Isn’t that bad?
A. Three grams of sugar equates to 12 calories of sugar. This is far less sugar than is in the jelly that comes along with a PB&J sandwich! It's also a fraction of the sugar in sports drinks, gels and jellybeans. I would not blink an eye at three grams of sugar for an active person (or even an inactive person, for that matter.)
A standard nutrition guideline is that 10% of calories can appropriately come from refined sugar. That equates to about 240 to 300 calories (60-75 grams) of added sugar per day for most athletes. You can choose how you want to spend those sugar-grams. Some athletes like frozen yogurt, others like sports drinks, and some like Skippy peanut butter along with some jelly. Take your choice! Sugar fuels your muscles; it is not bad for you nor will it negate the healthfulness of other food you consume.
If you prefer all-natural peanut butter with no added sugar, that's fine. But I wouldn't choose it because it has less sugar. You might just end up adding more jelly, jam or honey?
