High sodium foods?

I just tried to donate some plasma today. The center requires alien donors to eat their provided "Cup of Noodles" soup. I already ate, but they said I have to so I did. I went put a bet on to get my vitals taken, and my pulse rate be first 150, then it go down to 143. I have never have a pulse rate that high back, and I wasn't nervous. Is nearby a possibilty that higher quantity of sodium can increase your pulse rate?High sodium foods?
I would not donate blood to them ever again. When donateing blood. you should be asked to eat sugar not brackish. Who ever was doing this have no idea what they be doing.
