The Study
A macadamia nut-rich diet reduces total and LDL-cholesterol in mildly hypercholesterolemic men and women.
This study is like a fair test where people were randomly put into two diet groups to see how macadamia nuts affect cholesterol. It shows that eating these nuts might help lower bad cholesterol, but we can't be totally sure because we don’t know all the details about how the test was done.
