How to iterate through elements of the first column of a text file using bash?

I'm trying to grab each element in the first column of a text file using bash.

How can I read each element in as a variable? 

for ID_SAMPLE in cut -f1 manifest.tsv
do
echo $ID_SAMPLE
done


$ bash test.sh
cut
-f1
manifest.tsv

for ID_SAMPLE in $(cut -f1 manifest.tsv)
do
 echo $ID_SAMPLE
done

or backticks:

for ID_SAMPLE in `cut -f1 manifest.tsv`; do echo $ID_SAMPLE; done
