One who is repulsed by / dislikes something [duplicate]

Solution 1:

'Chocolate averse' or 'Chocolate-averse' might be candidates.

An example from 'The Local Fr' website (http://www.thelocal.fr/20110829/986):

Oscar Franco and colleagues from the University of Cambridge reviewed half a dozen studies covering 100,000 patients, with and without heart disease, comparing the group that consumed the most and the least chocolate in each.

They found that the highest level of chocolate intake was associated with a 37 percent reduction in cardiovascular disease, and a 20 percent drop in strokes, when compared with the chocolate-averse cohort.

No significant reduction was reported in the incidence of heart attack.

The original article from Oscar Franco is published and available on the British Medical Journal online site: http://www.bmj.com/content/343/bmj.d4488

The modifier '-averse' is perhaps most commonly seen in the combination 'risk-averse', and in associated business jargon word combinations such as 'Loss averse' and 'Change averse'.

Averse is an old word, from the Latin 'to turn away', and not to be confused with 'adverse'. From the Oxford English Dictionary:

averse ▪ I.averse, a. and n.
(əˈvɜːs)
Also 7 avers.
[ad. L. āversus, pa. pple. of āvertĕre to avert. Cf. OF. avers, in which L. āversus and adversus seem to have combined.]
A. adj.
1. Turned away, averted; turned in the backward or reverse direction. Obs.

The combination '-averse' appears to be a modern construction:
