Macadamia nuts are a delicious and nutritious snack offering various health benefits. They are a good source of healthy fats, fiber, vitamins, and minerals. Additionally, they contain antioxidants that can help protect the body against free radical damage.
Studies have shown that consuming macadamia nuts can help improve cholesterol levels and reduce the risk of heart disease. They have also been shown to help improve cognitive function and reduce inflammation.

How Much is a Serving of Macadamia Nuts?
The recommended serving of macadamia nuts is one ounce (or 28.35g) of macadamia nuts, which is equal to around 10-12 nuts or a handful.
A serving of macadamia nuts this size contains 204 calories. This might sound a lot because macadamia nuts are one of the highest-calorie nuts due to the fact they’re rich in natural fats.
