Are macadamia nuts good for you? Not if you're on a diet and trying to lose weight. They are actually the 2nd most calorie dense food. Only pure fats and oils (such as butter, lard, olive oil, coconut oil, etc.) have more calories.These nuts have a whopping 201 calories per ounce and almost 80% of that is pure fat (178 calories from fat). To add insult to injury, that one once only offers you 2% of your daily value of calcium, 1% of vitamin C, and 2 grams of protein. The amount of antioxidants in macadamia is quite low. With nutrition facts like that, it would be more logical to say they're bad for you. Or at least, they're not the best choice.
