What's considered a healthy snack in terms of sugar, fat and salt content.

this is due by tomorrow at noon california time.  I am writing an
article and would like to hear what researchers say are healthy amount
os slat, sugar and fat in snacks.  I already asked several health
experts and they gave many different answers.  So, it would be good to
hear more research.

I would like it in terms that people can relate with.  For instance I
say that 4. grams of sugar = one teaspoon, therefore one can now
understand the label a bit better.

I'd like a good way to explain the amounts of fat and salt contents in
a snack and what to look for.  Like my sugar example.  Now that people
know that 4.2 grams = a teaspoon, when they see a snack with 20 grams
of sugar, they know that it is closely 5 teaspoons of sugar in that
snack.  that is an easy way for them to pick their snacks.

Best wishes,
Elaine

In my opinion only friut and vegetables are healthy snacks as most
people get sufficient of the other food groups, but not enough fruits
and vegetables. Aditives such as aspertain, artificial colors,
flavors, presevatives etc also make "healty" doubtful.
As far as I know reverse spiral sugar and fat are not harmful except
to rather rare persons who are getting too few calories.   Neil
