Bronwynn,
Your list looks complete. On the ground flaxseed you were advised to mix with honey. If that does not work it may be best to either consume the seeds before you leave or when you come home or skip for that occasional day. Rancid oil from seed or nuts I think would be more harmful than good.
When we were in Cal. we use to go to the beach. So IN is a little too far for a day visit to the beach.
Best to you,
Nelson
*Pre-grind flaxseeds to add to the juice (I know I run the risk of them going rancid but I simply refuse to take a coffee grinder to the beach !! :) - There are no outlets there. :))
