Low in Carbs. High in Satisfaction.
4g
Net carbs per 1 oz serving · GI of just 10
With only 4g of net carbs and a glycemic index of 10, macadamias are a rare snack that fits naturally into low-carb and keto lifestyles — without sacrificing flavor or staying power.

The Anti-Inflammatory Nut.
6:1
Omega-6 to Omega-3 ratio · near-optimal balance
Macadamias have a near-ideal 6:1 Omega-6 to Omega-3 ratio — far better than the typical Western diet's 15–20:1 — making them a whole-food snack that naturally supports a healthy inflammatory response.

Heart-Healthy Fats That Actually Deliver.
16.7g
Monounsaturated fats per serving · highest of all tree nuts
More monounsaturated fat than any other tree nut — and more than avocado. Research shows a macadamia-rich diet can support healthier cholesterol levels and long-term cardiovascular health.*
The nut the Mac Pack can't stop talking about is available at Target, Walmart, Albertsons, and more. Find your flavor and taste what all the science is about.
