These are the best tasting tortilla chips I have ever had!  I have become allergic to tomatoes, but I love tortilla chips.  There is so much flavor in these chips that I no longer miss pico de gallo. I prefer to eat them plain. They also have just the right amount of heat to make them flovorful, but not overpoweringly spicy.

Ex Output:
Positive


Ex Input:
Dynasty brand green tea is the best green tea I've ever tasted.  It never tastes stale, unlike brands I've bought in grocery stores.  This is because each tea bag is packed in a sealed envelope with a metallic lining.  The metal apparently keeps out moisture.

Ex Output:
Positive


Ex Input:
I considered buying these but the health risks should be considered.  These are cured, stored with salt, and have nitrates.  If you look on the american cancer society web site you will see that those are cancer causing concerns.  you can still eat well when avoiding such things.

Ex Output:

Negative
