The basic principle to living a Paleo lifestyle is to eat plants, animals, nuts and seeds – in that order. Nuts can certainly be included as part of a healthy Paleo lifestyle as long as you remember to consume them in moderation.
Paleo and PUFAs
Nuts are high in omega-6 fats, a type of polyunsaturated fat (PUFA) that is inflammatory. In general, you should be sure to consume at least as much omega-3 fats (which are anti-inflammatory) as omega 6 fats, in order to counteract the inflammatory effects of the omega-6 fats.
Paleo and Whole Foods
However, even though nuts are low in omega-3 fats, they are high in other antioxidants, such as vitamin E, that help keep inflammation low. Consuming whole nuts (do avoid nut oils) has actually been linked to lower markers of inflammation.
To get the most out of your nuts, buy them whole and raw, then soak/sprout and roast them yourself. Remember our hunter-gatherer ancestors didn’t have access to pounds of nuts year-round. They ate them occasionally as they came across them, so the best way for us to enjoy our nuts is a handful at a time every now and then.
Even Mark Sisson advocates including nuts as part of a healthy diet.
