Raisin Bran is certainly a popular cereal, but unfortunately the most common Raisin Bran cereal brands (made by Kellogg's and Post) are not healthy for you. While the name "Raisin Bran" sounds healthy, it's actually loaded with calories and sugar - because of the amount of raisins included in the cereal. Raisins are dried fruit, and dried fruit overall is concentrated in sugar, since it doesn't have all of the water that its fresh fruit counterparts contain. One serving of Post's Raisin Bran cereal (1.25 cups) contains 210 calories and 20 grams of sugar. Kellogg's is no better - one serving (1 cup) contains 190 calories and 17 grams of sugar. That's almost the same amount of sugar in a can of Coke, or a regular sized Snickers Bar! For a healthy Raisin Bran type cereal, try Nature's Path Flax Plus Raisin Bran instead.
