Brand A: 240 MG sodium for 1/3 pickle or Brand B: 325 MG sodium for 1/2 pickle
Blababa [14]
<span><u>Brand A:</u>
240 mg sodium in 1/3 pickle ===> 720 mg sodium in a whole pickle.

<u>Brand B:</u>

325 mg sodium in 1/2 pickle ===> 650 mg sodium in a whole pickle.

When I feel like enjoying a pickle, I would choose one from Brand A.
A nice firm, natural, organic, green Brand A would be more effective
at treating my sodium deficiency without pills or medication or other
kinds of un-natural chemicals. 

To make it even more healthy, I can squeeze the juice of a plump Brand A
onto my daily 5-egg cheese omelet, and treat my cholesterol deficiency at
the same time.</span>
