The difference between 100 calories and 150 calories isn't much.
I went and looked and a 'light' twinkie has 130 calories so the calorie difference is even less.
What you can get for 100 calories or even 130 calories seems a lot better (and cheaper) than 100/130 calories worth of twinkies.
My favorite snacks -
Medium sized banana - 105 calories (fiber, potassium, a bit of protein as well)
Large apple - 110 calories (fiber, potassium and calcium)
1/4 cup of shelled edamame - 94 calories (fiber, lots of calcium, lots of potassium and good source of protein)
1/4 cup of raw almonds - 133 calories (good fats, fiber, protein, calcium and potassium)
What does a twinkie give you besides a sugar rush and insulin spike which causes more sugar cravings?
I do think the world has gone mad if 100 calories of junk is considered a sensible snack
