"Daily consumption of wholemeal bread was associated with a 12% reduction in all
cause mortality, but the protection was much less than that for fresh fruit
(21%) and became non-significant after fruit was adjusted for. Daily
consumption of raw salad was associated with a 26% reduction in mortality from
ischaemic heart disease, slightly greater than that for fresh fruit (24%)."

"After smoking was adjusted for, daily consumption of fresh fruit was
associated with a 24% reduction in mortality from ischaemic heart disease, a
32% reduction in mortality from cerebrovascular disease, and a 21% reduction
in all cause mortality compared with less frequent consumption."

"The 41% reduction in mortality from lung cancer associated with daily consumption of fresh fruit was not significant but is consistent with previous studies"

"For all cause mortality, Kahn et al reported odds ratios of 0.89 and 0.72 for frequent
versus infrequent consumption of fruit or fruit juice and green salad
respectively,[9] Pandey et al reported a 31% reduction with a high intake of
foods rich in vitamin C and in [beta] carotene,[10] and Enstrom et al reported
a 23% reduction associated with high vitamin C consumption.[11] Fruit is an
important source of vitamin C. Fruits and vegetables,[12 13] carotene
containing fruit and vegetables,[14] apples,[15] and foods rich in vitamin C
and [beta] carotene[10] have all been reported to protect against ischaemic
heart disease. Fruit and vegetables have also been reported to protect against
stroke,[16 17] as have potassium[18] and vitamin C[19]--nutrients for which
fruit is an Important source."
