    Will someone please explain to me why peanuts are so bad

    Primal Fuel
    I get why we aren't supposed to eat grains and sugar and stuff, but why are peanuts so bad?

    they are legumes, and as most legumes, their problems are:

    a) their proteins are toxic to humans.
    b) their fats have a bad omega 6:3 ratio.

    All nuts have poor Ω6:Ω3 ratios which is why they should be eaten in very limited quantities. Peanuts, while they have heart healthy monounsaturated oil, have an exceptionally poor Ω3:6 ratio

    from nutritiondata.com
    Peanuts - per ounce 4000:1 Ω6:Ω3 ratio
    Total Omega-3 fatty acids 0.8 mg
    Total Omega-6 fatty acids 4355 mg

    Macadamia nuts - per ounce 6:1 Ω6:3 ratio
    Total Ω3 fatty acids 259 mg
    Total Ω6 fatty acids 1720 mg

    Walnuts 4:1 Ω6:3 ratio
    Total Ω3 fatty acids 2542mg
    Total Ω6 fatty acids 10666 mg

    Pistachios 52:1 Ω6:3 ratio
    Total Ω3 fatty acids 71.8 mg
    Total Ω6 fatty acids 3729 mg

    The biggest argument here though, may be simply that they are a legume - albeit an oily, fatty, higher protein legume. Legumes aren't biologically appropriate for humans as they were not eaten in an evolutionary environment - at least not in any significant quantities. Based on that line of thinking though - we'd also not be eating dairy or most high fat meats (as most wild meat is much lower in fat and has been eating only plants it's whole life, not grains). We'd also not be eating any 'free fat' but rather only fat as it occurs in animal and plant foods.


    Peanuts are often infected with a toxic mold called aflatoxin - that may or may not be a concern:

    Oh wow, thanks for asking this and Kat, thanks for answering. I wondered this myself, as I love PB.

    ...though studies of hunter gatherers showed they would preferentially eat the fattiest part of the animal - the bone marrow, organ meats, etc. and sometimes even get rid of the leaner parts in times of plenty. Cordain argues on the lower side of fat, other researchers and if one reviews some observations of those who lived with hunter gatherers in the past several hundred years will argue that hunter gatherers ate more fat. Typically, though, they would eat starchy carbs rather than low carb veggies if they could get away with it. None of them had leptin or insulin resistance and none of them were trying to lose fat. Times a-change!

    I used to be upset about giving up peanuts. Until, that is, I discovered that almonds and almond butter are totally interchangeable in recipes.

    How do we know peanuts weren't around during grok's time? And what classifies a legume as a legume? Since we aren't supposed to eat grains and sugar since grok didn't, does that mean that in our bodies legumes are equally as bad as grains/sugar?

    Whether or not they were, they're not healthy. The evolutionary axiom is only useful for making a hypothesis or a speculation. If empirical evidence contradicts something, we have to defer to the conclusion.

    Also we have to consider the quantity that something would have been found in. Nuts were eaten throughout evolution but not in any meaningful quantity.

    Archeologists have (thus far) dated the oldest specimens to about 7,600 years found in Peru .[5] Cultivation spread as far as Mesoamerica where the Spanish conquistadors found the tlalcacahuatl (Nahuatl = "cacao", whence Mexican Spanish, cacahuate and French, cacahučte) being offered for sale in the marketplace of Tenochtitlan (Mexico City). The plant was later spread worldwide by European traders.

    The legume gained Western popularity when it came to the United States from Africa. It had become popular in Africa after being brought there from Brazil by the Portuguese around 1800.

    USDA classifies the peanut as a legume...

    The peanut, or groundnut (Arachis hypogaea), is a species in the legume "bean" family (Fabaceae). The cultivated peanut was likely first domesticated in the valleys of the Paraguay and Parana rivers in the Chaco region of Paraguay and Bolivia.[1] It is an annual herbaceous plant growing 30 to 50 cm (0.98 to 1.6 ft) tall. The leaves are opposite, pinnate with four leaflets (two opposite pairs; no terminal leaflet), each leaflet 1 to 7 cm (⅜ to 2ľ in) long and 1 to 3 cm (⅜ to 1 inch) broad. The flowers are a typical peaflower in shape, 2 to 4 cm (ľ to 1˝ in) across, yellow with reddish veining. After pollination, the fruit develops into a legume 3 to 7 cm (1.2 to 2.8 in) long, containing 1 to 4 seeds, which forces its way underground to mature. Hypogaea means "under the earth."

    And this is what Mark says about legumes:

    And if you want to eat peanuts...fit them into the pyramid with legumes

    Whole9 has a peanut manifesto (among other manifestos that are worth reading) here http://whole9life.com/2009/12/peanut-manifesto/

    Short version is: lectins are bad, peanuts have lectins.
