Macadamia nuts have the best omega 3:6 ratio, but also a low amount of both fats in the first place. Most of its fats are monounsaturated fats (Omega 3s and 6s are polyunsaturated fats). Walnuts have the 2nd best ratio, but also one of the highest raw amounts of omega 6, which is also something you want to minimize.

Do macadamia nuts contain omega-3?

They are high in monounsaturated and polyunsaturated fats and omega-3 fatty acids. They are also a good source of protein.

Do macadamia nuts have omega 6?

Macadamia nuts really reduce one of the major problems with most other nuts: fat quality. That's almost no Omega-6 in the macadamias – it's less than you'd find in 1 tablespoon of olive oil, and olive oil is already low in Omega-6.
