Overview

Macadamia nut is the seed of the macadamia tree. Macadamia nuts are native to Australia. They are grown commercially in Hawaii and, to a much smaller extent, in California and Florida.

Roasted macadamia nuts are a popular snack. But some people also use macadamia nuts as medicine to lower high cholesterol.

How does it work?

Macadamia nuts contain monounsaturated fatty acids (MUFA) and plant substances that might lower cholesterol.

Uses & Effectiveness

Possibly Effective for...

  • Lowering cholesterol. Eating macadamia nuts as part of a healthy diet seems to lower total and “bad” low-density lipoprotein (LDL) cholesterol, and to raise high-density lipoprotein (HDL) cholesterol. But the changes aren’t huge. Men with high cholesterol who eat 17-37 nuts per day for four weeks can see their total cholesterol drop by about 3%, their LDL cholesterol drop by about 5%, and their HDL rise by about 8%.
