Special Diets/phytic acid


This question relates to all this talk about trying to avoid phytic acid (phytates) in food (e.g. grains, beans, nuts) because it supposedly blocks mineral absorption, things like calcium, magnesium, phosphorus, iron, zinc.  By avoiding phytic acid foods, I've seen everything from curing tooth decay to curing all sorts of other diseases in the body.  I thought it was just the opposite for phytic acid, where it prevents diseases and a host of other things in the body.  I thought these were really good foods to try and eat every day, and this should make up the bulk of your diet.  Is this something to worry about?  Are important minerals not being absorbed?  How much scientific proof is there to this?  I try to take my vitamins every morning with breakfast since it was always told to do this for best absorption.  Now I'm thinking twice about this.  I like my bowl of oatmeal every morning, but am now worried vitamins/minerals are not being absorbed.  I also like my grains.  Is hard to really know what's truth and not truth out there on the internet, since things many times seem so valid.  Thanks.

Grains cause all sorts of problems. Some are related to the antinutrients in grains, such as phytic acid, but there are many other substances in grains that cause problems. For example grains consumption can lead to coeliac disease, IBS and many other conditions.The gluten in grains is particularly dangerous:-

I would strongly suggest avoiding all grains and beans. Nuts can be consumed in moderation but I would always suggest soaking them in water for 24 hours before eating them as this reduces the amount of antinutrients in them.

I can answer most questions on Raw Animal and Vegetable Food Diets such as the Primal Diet, an organic, raw-meat-based diet and a number of similiar all-raw or partially raw Paleolithic diets, such as the Instincto, Weston-Price, Neanderthin, Paleo and Stefansson Diets. Can also offer advice on how to resist social pressure to eat cooked foods etc. For further info on Raw-Animal-Food diets, it's a good idea to browse through GoodSamaritan's website, , and also to join the following two forums and read their message-archives :- and


I have been 10 years on a 99%+ raw version of the Palaeolithic Diet and experienced numerous health benefits as a result, being fully recovered from my previous symptoms from my cooked-food days. My own individualised raw, paleolithic diet routine is mostly based on Aajonus Vonderplanitz's Primal Diet(ie 99% raw, usage of "high-meat",no processed supplements, using primarily naturally-reared, organic or wild sources of raw foods) but, for personal reasons, I have also been, to some extent, influenced by ideas from:- Instincto(ie:- taste/instinct,no raw dairy/no raw veggie juice), Weston-Price(eg: preferring grassfed meat to grainfed meat, incorporating a wide variety of raw organ-meats into my diet along with the usual muscle-meats, and Vilhjalmur Stefansson(high-fat diet, pretty high proportion of (raw) animal food), but also eating some raw carbohydrates such as raw organic/wild fruit/veg/honeycomb etc.). I'm also a firm believer in the feast-and-famine idea (ie Intermittent Fasting) as regards boosting one's energy levels, and giving my body a rest from constant digestion.

No nutritional qualification(I don't believe in standard(misguided) nutritionist doctrine, so I don't feel the need). I simply rely on mine and many others' long-term experiences of raw, palaeolithic diets and I've read most of the books that are vaguely relevant to a raw-meat diet.
