Special K original cereal looks healthy, but it's actually not that healthy for you. There are some positives: it's low in calories (150 calories for 1.25 cups), high in protein (7 grams per 1.25 cups), and low in sugar (5 grams per 1.25 cups). But it has no fiber, includes BHT, and Special K was also one of the cereals found to contain glyphosate, so I would recommend avoiding it and choosing one of the other healthier cereal choices on this list above.
