I remember when I was a kid in the 70s the meals at McDonalds came with the "small" fries that were actually a small order. By the time I was a teen the "small" was the old medium size.. and now I think its the large size.

Also, when I was a kid you could get sodas in the half-can sizes which dissappeared sometime in the 80s. Although, I actually saw some of these at Walgreens the other day with a big sign about the "new" smaller size for dieters.

All in all, going back to smaller portions for the junk can only be a good thing.
