Heart disease is all-too-common, especially in the United
States. Although there’s a definite tendency for heart disease
to run in families,
lifestyle factors such as diet, smoking and stress also play
a substantial role. Dietary practices have long been linked
to heart disease, especially the consumption of foods that
help lower cholesterol levels.
A study published in the Archives of Internal Medicine
evaluated the cholesterol-lowering ability of macadamia nuts
in 30 volunteers, aged 18-53. Subjects consumed three specific
diets in random order: a “typical American diet,” with 37%
of energy derived from fat; an American Heart Association
“Step 1” diet, with 30% of energy from fat; and a macadamia-nut
based diet, with 37% of energy derived from primarily monounsaturated
After one month, cholesterol levels were lower in the group
consuming the macadamia nut diet, compared with the other
two groups. The typical American diet proved the least effective
of the three diet plans in lowering cholesterol. No significant
side effects were noted from ingesting large quantities of
macadamia nuts, leading the authors to conclude: “Physicians
can recommend the consumption of these and other nuts as part
of a satisfying and healthy diet.”
