My own personal inventory on what I've tried during this food journey. It all started with an elimination diet that I undertook in search of a calm tummy and clear skin. After two years of buying and trying new foods and products, here's my round-up:

Like, still use, would buy again:
Almond milk (unsweetened) - prefer over coconut, soy, or rice
Almond butter - use in smoothies and for a treat on dates...the food kind ;)
Amaranth - hot breakfast grain I like with almonds + fruit like mango
Cream of Buckwheat - another hot breakfast I like with brown sugar or maple syrup + raisins or cranberries
Chia seeds - makes a nice little pudding with almond milk (that I rarely make)
Coconut butter - yummy in smoothies
Coconut oil - seems to work well for cooking
Fish oil - capsules I forget to take but seem consistently recommended
Flax - ground or liquid in smoothies
Hemp seeds - rarely use but could throw in salads, smoothies, cereal
Sorbet - I have to remind myself that ice cream isn't the only answer...
Apple cider vinegar - I used to take a teaspoon every morning which I can't stand anymore ;) but it's still great for other purposes.

Unsure:
Bee pollen - easy enough to put in smoothies but remind me what's so special about it? ...Virility?
Tahini paste - sometimes I put it in smoothies (with cacao + banana) but otherwise not sure what to do with it
Millet - haven't found an easy recipe yet that I love
Mung beans - same as above
Bragg's Liquid Aminos - basically...I like soy sauce!
Goat milk Kefir - tastes good but trying to avoid dairy (cheese being an exception...)
Kelp noodles - terrible taste that I tried to rinse off. Maybe I just had a bad batch?
Macro Greens superfood - I like adding it to smoothies or apple juice, or but it's expensive and must be pretty engineered, plus in Food Rules, Michael Pollan says to eat like  someone who takes supplements but to then save your money and not bother buying them.
Gluten-free products - I would if I had to, but since I don't have Celiac, I'd rather eat the real thing, just less frequently than before.
Note to self: remember rice, lentil, & quinoa!

No need, I wouldn't buy again:
Wheat grass powder - is this what gave me heart burn that I panicked was breast pain (cancer), thereby bringing on my first ever mammogram...?!?
Natural Calm - never got into it
Pili nut butter - it seemed so yummy at first when I was just plain hungry from my elimination diet, but now I feel no desire for it
Stevia (liquid) - yucky aftertaste
Goji berries - don't love them, not even sure how to use them up except to put in hot cereal
Kombucha - blech!

Specific products I've found that I love:
Hilary's veggie burgers (all flavors)
Kit's Organic bars (all flavors)
