I just learned that a peanut is not a nut but rather a legume. Go figure? I also learned that legumes and nuts are not really all that they are cracked up to be (pun intended). From the website, paleodietlifestyle.com, I offer the following information on nuts and legumes:
Grains and legumes are king when it comes to antinutrients, lectins, enzymes inhibitors and toxic proteins, but some nuts and seeds use similar defense mechanisms. Of course, unlike some very nasty plaint proteins (e.g. gluten), longterm damage and autoimmunity is unlikely to happen from eating nuts and seeds.
Lectins in some nuts and seeds can irritate the gut lining and create inflammation and enzyme inhibitors can prevent the full digestion of the proteins in them.
Phytic acid is a strategy employed to prevent the nut or seed from sprouting before the ideal conditions are present. Phytic acid on our digestive system has the property of binding to minerals like calcium, iron and magnesium and preventing them from being absorbed. This also means that you won’t necessarily get high amounts of a mineral even if you eat a nut high in that mineral.
