Ex Input:
The carbonation in this drink was way too much. So much in fact, that it over powered the flavor. (Orange-tangerine is usually very good together).  I expect this from a soda, but not a "healthy" drink. Lose some of that club soda bite and you have one delicious drink. Until then, I'll pass.

These are great little snack packs - flavorful chips and fairly low fat and low cal.

These Flaxseeds are of good quality, I eat them daily.  Bought the whole seed, rather than the ground seed, because of the better nutritional value of grinding your own.  Will buy again.  I read that whole seeds can pass undigested, and that ground seeds can loose their nutritional value over time.  So we grind a week's worth at a time.  Best used in oatmeal as the flavors blend well.  Or in a cold cereal, or added to a cup of coffee for a twist. Seem to blend better in hot foods.
