Over the last couple of years, my family has made diet changes based on our health issues. I have been struggling with my gut issues for awhile. So, my family is eating fewer grains and more nuts from almond milk, almond flour, and raw nuts. While investigating my issues, I learned that their nut consumption might be causing more harm than good. Seeds, nuts, beans, and grains all contain phytic acid, which could have detrimental health effects. Read on to learn why soak nuts.
Before I begin. I am not a doctor, nor am I dispensing medical advice. I just want to share with you what I have learned. Then, you make up your mind.
Back to the family.
Some Historical Health Background.
The older boys are now following Tim Ferris’ 4 Hour Body, which is a low-carbohydrate, no grains, and no fruit diet. (I call it the “I want a six pack” diet since it focuses on burning fat as fuel for your body.) He does allow some nuts, but not too many.
Oldest boy is gluten-free since he is sensitive. (He breaks out in rashes when he eats gluten.)
Hubs is following more of an Atkins diet which is a no carbohydrate diet with good fats to get his blood sugars under control. Last child dislikes most foods and follows the “I love meat” diet.
I have to cook for their variety of diets and look for common ground. (Yes. I have become a short order cook.)
So our household is now consuming almond milk, nuts, almond flour, and occasionally gluten-free grains. (You get one cheat day on Ferris’ program.)
As you know, I have been struggling with my gut health and started to soak my nuts to make them more digestible. I am not a nut lover because I find that I can’t eat just a few. The rest of the few wind up on my hips.
You probably are asking why don’t they drink coconut milk in lieu of almond milk? The older boys simply don’t like the taste of coconut milk. I prefer coconut milk.

Learn Why Soak Nuts
Okay, back to the problem at hand–phytic acid. There seem to be two camps on this theory. Some think that as long as you eat a diet rich in leafy greens, meat, and seafood, phytic acid isn’t a problem. Others think phytic acid can cause mineral absorption problems.
What is Phytic Acid?
According to a study by Enrico Doria, Luciano Galleschi, et al.,
“[p]hytic acid is the primary storage form of phosphorus in seeds, representing 50% to over 80% of total phosphorus in mature seeds and accounting for one to several percent of the dry weight.”
The primary function of phosphorus in seeds is an antioxidant for germinating seeds, as well as the storage of phosphates for energy. So, the seed uses the phytic acid to protect itself.
What is the Problem with Phytic acid?
Here’s my research:
Seeds such as beans, grains, and nuts contain phytic acid.
New York Times best-selling author Chris Kessler, M.S. L.Ac, states in his article, “Another reason you shouldn’t go nuts on nuts,” that nuts contain more phytic acid than grains. He warns people who opted for a Paleo lifestyle, not to go overboard with eating nuts on lieu of grains.
We use almond flour in many bread or dessert recipes. In fact, I add almond meal to a zucchini recipe to give it body. The boys drink almond milk. We have become an almond joy family.
Kressler provides an excellent chart on the breakdown of foods that contain certain phytic acid levels.
Just to give you some nut examples, according to Kressler’s chart based on milligrams per 100 grams of dry weight, certain nuts contain the following levels of phytic acid levels:
Brazil Nuts–1719
Almond 1138-1400
Walnuts–982
Peanuts ungerminated –821
Hazelnuts 648-1000
On the other hand, coconut meat (357) corn (367) and polished rice (11.5) contain significantly less phytic acid.
Studies have shown phytic acid can:
Reduces iron absorption.
Reduces absorption of zinc and magnesium.
Interferes with digestion enzymes that help to break down proteins in our stomach and small intestine and starches.
On the other hand, according to Dr. Michael Roussell, Ph.D., a nutritional consultant argues in Shape Magazine‘s article that we shouldn’t worry about phytic acid if we are eating a healthy diet. He states:
“However, nuts, seeds, and cereal grains are not the only sources of these nutrients, and most often they aren’t even a key contributor in your diet. The major sources of iron, calcium, magnesium, and zinc for most Americans are:
Iron: Red meat, seafood, nuts, dark green vegetables
Calcium: Dairy, dark green vegetables, beans
Magnesium: Spinach, nuts, and seeds (I recommend supplementing with extra magnesium anyway)
Zinc: Seafood (shellfish), meat, nuts”
The question is, do we eat a healthy diet?
In the meantime, I am soaking my nuts. Plus, I like the taste of dehydrated nuts.
Learn How to Soak Nuts.
I use the authors, Sally Fallon and Mary Enig’s Nourishing Traditions method of soaking. Most nuts are very similar with some variation based on their density.
1. Use chlorine-free water in a 2:1 ratio of water to seed.
2. Add salt to the water before adding the nuts. Dissolve the salt. (I buy this unrefined salt.)
3. Add the nuts.
4. Let it stand for in a warm place for 7 hours or more. Put a pot lid on top. I tend to soak overnight. Note, soak cashews no more than 6 hours. They can get really slimy otherwise.
5. See how much salt to add to each batch below.
6. After the nuts soak, pour out the water and rinse the nuts.
7. Dehydrate them for 12 to 24 hours in a dehydrator or your oven. I set my oven at 135 degrees. In my dehydrator, I set the temperature at 105 degrees. (I have this dehydrator.)
It takes 24 hours for the seeds to dry. I err on the side of more time since I don’t want the nuts to mold.
(You don’t have to dehydrate them if you are using it for something like nut milk or a recipe that uses wet ingredients like a dessert. Be sure to use your soaked nuts for nut butters too.)
8. Store in the refrigerator or air-tight container. I use the nuts right away.
Salt per Nut:
Almonds, Peanuts, Pine Nuts, Cashews, Macadamia, and Hazelnuts: 1 Tablespoon of salt per 4 cups of nuts.
Remember to only soak Cashews no more than 6 hours and be sure the cashews are raw, not the salty kind.
Pecans and Walnuts: 2 tablespoons of salt per 4 cups of nuts
Pumpkin: 2 Tablespoons per 4 cups of nuts.
Taste?
As I mentioned above, I happen to like the taste of dehydrated nuts. Walnuts aren’t as bitter when dehydrated.
So this may be a bad thing or a good thing. I do find my hands reaching for the dehydrated nuts until my hips start to scream, “walk away from the nuts. Just simply walk away.”

Do you soak nuts and if so, do you find that you digest them better?
PS I am thinking of growing an almond tree. Am I nuts?

green Bean says
Whew! I’m tired just thinking about all the cooking you do. 😉 Seriously, I had no idea about soaking nuts. My husband eats a ton of them. I’ll have to think about soaking them.
Anna@Green Talk says
Green Bean, I like to soak things and walk away. Same with beans. Soak and walk away. I am not a stand in front of the stove girl. Try soaking them. They taste so much better dehydrated. Anna
sticks says
I’ve been soaking & dehydrating nuts for some time & find them more satisfying so it is easier to eat just a few.
Jessica says
We soak our nuts too. I think they taste so much better.
Anna@Green Talk says
Jessica, they taste so good that I have to slap my hands from eating them all. Anna
Megan Stevens says
Love it, Anna, thanks for your post and sharing some of your family’s process.
Anna@Green Talk says
Megan, you are welcome. Anna
Renee says
This is such important information. Thank you for sharing!
emily @ Recipes to Nourish says
Thanks so much for this thoughtful post. Soaking nuts is so important but many people don’t know about this. Thanks for sharing this info with us.
Anna@Green Talk says
Emily, I agree. I never knew until a year ago. Now it is a monthly ritual. So easy to do. Anna
Loriel says
Soaking nuts was one of the first things I learned to do when switching over to a real food lifestyle. I love how crispy they get after soaking and dehydrating!
Anna@Green Talk says
I was surprised how much better the nuts taste! Anna
Karen says
We add beans to rice when we cook and always soaked the beans overnight (rice, less) because they don’t cook when we don’t. But I never soaked nuts just to dehydrate them again. We soak nuts when we want to use them the next day. Phytic acid is not a big concern to me as I tend to agree with Dr. Roussell that we intake a lot of nutrients from other foods. I don’t worry about the little amount of nuts I eat not absorbing the nutrients in my diet.
But your family, on the hand, might be different since you sounds like you’re eating a lot of nuts in your diet.
I have one question though. What does adding salt when soaking do? Is that just for flavor or for mineral? Just curious.
Anna@Green Talk says
Karen,
We soak our beans too.
As for the nuts, salt is necessary to help neutralize the enzymes. Anna
Krystal says
Thank you for such a thoughtful and informative post!
Rachel @ day2dayjoys says
I need to get back into the habit of this!
Judith says
I have been soaking and dehydrating my nuts as well, as I have been following the SCD (Specific Carbohydrate Diet) for awhile, so nut flours and nut butters are a big part of that! However, I have been using apple cider vinegar instead of salt when soaking my nuts – I wonder what the difference is in terms of neutralizing the enzymes?
Anna@Green Talk says
Judith, I think the salt is the only thing you can do to neutralize the enzymes. I follow Nourishing Tradition’s method.
I use apple cider vinegar to soak my grains. Anna
