lest

I'm a little stuck... Click here to teach me more about this clue!

'just in case' is the definition.
(I've seen this in another clue)

'need cholesterol reduction' is the wordplay.
'LEST' is hidden in amongst the letters.
However, I'm uncertain how the hidden word is indicated.

'you' acts as a link.

Can you help me to learn more?

(Other definitions for lest that I've seen before include "For fear that (something happens)" , "To avoid the risk that - let's do it" , "In order not to, say forget?" , "In case" , "For fear that (something should happen)" .)
