Weak Example
Previous work has shown that a purified pro-oxidant, vitamin E-deficient fish oil diet protects mice against malaria parasites.
Improved Example
Previous work has shown that feeding a pro-oxidant diet containing fish oil, but devoid of vitamin E, protects mice against malaria parasites.
