All three statements are true. This just in;
Nearly All Heart Risk Due To Bad Habits
8-20-03
CHICAGO (Reuters) -- The vast majority of heart attacks strike
people who either smoke, have high blood pressure, high cholesterol
or diabetes, debunking the perception that heart problems can strike
anyone, researchers said on Tuesday. Roughly nine out of 10 patients
surveyed suffered from one of the four risk factors, often for years,
before experiencing a heart problem, according to a pair of reports
that analyzed accumulated data from previous studies.
..
Based on these and related findings concerning the major risk factors,
we suggest that preventing development of unfavorable levels of blood
cholesterol and blood pressure, cigarette smoking, diabetes, and
unfavorable body weight (as a precursor of unfavorable blood lipid
and blood pressure levels and diabetes) should be given even greater
priority than is presently the case, he wrote.
..
It is increasingly clear that the four conventional risk factors and their
resulting health risks are largely preventable by a healthy lifestyle, wrote
study author Umesh Khot of Indiana Heart Physicians in Indianapolis.

We assessed the effect of a diet high in leafy and green vegetables,
fruit, and nuts on serum lipid risk factors for cardiovascular disease.
Ten healthy volunteers (seven men and three women aged 33 +/- 4
years [mean +/- SEM]; body mass index, 23 +/- 1 kg/m2) consumed
their habitual diet (control diet, 29% +/- 2% fat calories) and a diet
consisting largely of leafy and other low-calorie vegetables, fruit, and
nuts (vegetable diet, 25% +/- 3% fat calories) for two 2-week periods
in a randomized crossover design. After 2 weeks on the vegetable diet,
lipid risk factors for cardiovascular disease were significantly reduced
by comparison with the control diet (low-density lipoprotein [LDL]
cholesterol, 33% +/- 4%, P < .001; ratio of total to high-density
lipoprotein [HDL] cholesterol, 21% +/- 4%, P X .001; apolipoprotein
[apo] B:A-I, 23% +/- 2%, P < .001; and lipoprotein (a) [Lp(a)],
24% +/- 9%, P = .031). The reduction in apo B was related to
increased intakes of soluble fiber (r = .84, P = .003) and vegetable
protein (r = -.65, P = .041). On the vegetable compared with the
control diet, the reduction in total serum cholesterol was 34% to 49%
greater than would be predicted by differences in dietary fat and
cholesterol. A diet consisting largely of low-calorie vegetables and
fruit and nuts markedly reduced lipid risk factors for cardiovascular
disease. Several aspects of such diets, which may have been consumed
early in human evolution, have implications for cardiovascular disease
prevention.
