I avoid raisins because they're little sugar bombs, as is most dried fruit - way too high in sugar and calories for me. But I was so intrigued by the comparison of raisins and Hershey's Kisses that I had to go look them up!
For 40 grams of each:
Raisins
130 calories
0g fat
31g carbs, of which 29g are sugar
2g fiber
1g protein
Hershey's Kisses
240 calories
14g fat
21g carbs, of which 19g are sugar
1g fiber
4g protein
So both are sugar bombs, but the Kisses have 10 fewer grams of sugar (surprisingly!). But Kisses have a ton of fat and raisins have none. And thus Kisses have almost twice as many calories as raisins.
I can't say that either are 'health foods' but I think you're better off with the raisins than the Kisses for your sweet tooth.
