what about:

sysuse auto, clear
foreach x in "mpg" "price" {
	di _n as input ". ttest `x', by(foreign)"
	ttest `x', by(foreign)
}

The _n in the -di- command results in a new line, and the -as input- in
the -di- command makes sure that the string is displayed as input, and
the string is the command you are giving Stata.
