Incorporating macadamia nuts into a heart healthy diet can reduce cardiovascular disease risks according to Penn State researchers.

“We looked at macadamia nuts because they are not currently included in the health claim for tree nuts, while other tree nuts are recommended as part of a healthy diet,” says Dr. Amy E. Griel, recent Ph.D. recipient in nutritional sciences. “Macadamia nuts have higher levels of monounsaturated fats, like those found in olive oil, compared with other tree nuts.”

The researchers used a controlled feeding study to compare a heart-healthy diet with 1.5 ounces – a small handful of macadamia nuts – to a standard American diet. The participants had slightly elevated cholesterol levels, normal blood pressure and were not taking lipid lowering drugs. Researchers randomly assigned participants to either the macadamia nut diet or the standard American diet, providing all meals for the participants for five weeks. The participants then switched diets and continued eating only food provided by the researchers for another five weeks.

The Healthy Heart diet with macadamia nuts did reduce total cholesterol, low-density lipoprotein cholesterol and triglyceride levels compared with the standard American diet. “We observed a reduction in LDL similar to that seen with other tree nuts like walnuts and almonds,” says Griel.

Individual calorie levels were used for each participant so that they did not gain or lose weight during the study. Both diets were matched for total fat, containing 33 percent calories from total fat. …

The macadamia nut diet included macadamia nuts as a snack, mixed into meals, as a salad topping and in cookies and muffins. …
