Eating walnuts is a great way to boost your intake of healthy fats, antioxidants, protein, and essential minerals. However, many people don’t realize that soaking walnuts before consuming them can significantly enhance their nutritional value and improve digestion.
In this comprehensive guide, we’ll walk you through everything you need to know about soaking walnuts, including why it’s beneficial, how to do it correctly, and tips for storing and using soaked walnuts in your daily routine.
Why Should You Soak Walnuts?
Nuts, including walnuts, naturally contain enzyme inhibitors and phytic acid. These compounds help protect the nut in its raw, dormant state but can interfere with the digestion and absorption of nutrients when consumed unprepared. Soaking walnuts helps mitigate these effects through a process known as activation.
What Happens When You Soak Walnuts?
When walnuts are soaked in water (often with a pinch of sea salt), the following beneficial changes occur:
- Reduces enzyme inhibitors: These substances can interfere with digestive enzymes in humans, making it harder to break down food efficiently.
- Decreases phytic acid: Phytic acid can bind to minerals such as iron, zinc, and calcium, reducing their bioavailability. Soaking begins to break it down, allowing your body to absorb more nutrients.
- Enhances texture and flavor: Soaking can soften the texture and make walnuts taste richer, especially if you plan to use them in dishes or snacks where a creamier consistency is favorable.
Why Nutrition Experts Recommend Soaking
Registered dietitians and holistic nutritionists often suggest that soaking raw nuts (and seeds) can greatly enhance their nutritional profile. This method is especially beneficial for individuals with sensitive digestion or those aiming to maximize nutrient absorption from plant-based sources.
How to Soak Walnuts: Step-by-Step Instructions
Soaking walnuts is a straightforward process that requires minimal time and effort. Here’s a detailed guide to ensure you do it correctly for optimal benefits.
Step 1: Select Raw, Unsalted Walnuts
Only raw walnuts should be soaked. Avoid pre-roasted, salted, or flavored walnuts, as they may have been processed in a way that diminishes nutrient availability and can contain additives that interfere with the soaking process.
Step 2: Choose the Right Soaking Medium
Use filtered water for soaking walnuts to avoid impurities. Some people add a pinch of sea salt to the water, which can encourage the activation of enzymes that reduce antinutrients.
Step 3: Soak in a Bowl or Mason Jar
Place your desired quantity of walnuts (1 to 2 cups) in a bowl or glass jar. Pour in enough filtered water to completely submerge the nuts. If you’re using salt, add ½ to 1 teaspoon of sea salt for every 4 cups of water.
Step 4: Cover and Let Sit
Cover the container with a clean towel or lid and leave the walnuts at room temperature. The ideal soaking time for walnuts is generally 7–12 hours, depending on the desired texture and personal preference.
Unlike almonds or cashews—which may begin to sprout after soaking—walnuts are usually soaked for hydration rather than sprouting. Hence, soaking them overnight is convenient and effective.
Step 5: Drain and Rinse
After soaking, drain the walnuts in a strainer and rinse them thoroughly under cool water. This step removes any residual enzyme inhibitors, phytic acid, and the salty soaking solution (if used).
Step 6 (Optional): Dehydrate for Crispy Results
If you prefer a crunchy snack, you can dehydrate soaked walnuts in a low-temperature oven or a dehydrator.
Using a dehydrator:
- Set temperature to 105–115°F (40–46°C).
- Spread walnuts in a single layer on trays.
- Dehydrate for 10–12 hours until completely dry and crisp.
Using an oven:
- Preheat oven to its lowest setting (usually around 150°F or 65°C).
- Spread nuts on a baking sheet lined with parchment paper.
- Oven-dry for 6–12 hours, flipping occasionally to ensure even drying.
Dehydration mimics the sun-drying effect in traditional food preparation methods while preserving the living enzymes and nutrients.
How Soaking Affects the Nutritional Profile of Walnuts
Soaked walnuts are not only more digestible but also more nutritious. Studies have shown that nut soaking, especially when followed by slow dehydration, can lead to the following benefits:
Increased Vitamin and Mineral Absorption
Soaking helps release enzyme inhibitors and reduce phytates, allowing your body to access more iron, zinc, magnesium, and calcium. In particular, walnuts are known for being a good source of magnesium and potassium, which are important for heart health and nerve function.
Boosted Antioxidant Activity
Soaking and activating walnuts may also enhance the bioavailability of antioxidants, particularly polyphenols that help combat oxidative stress in the body, supporting long-term wellness.
Improved Nutrient Bioavailability
Proteins and healthy fats in walnuts become more bioavailable after soaking. This is especially important for people following plant-based diets, where optimizing nutrient access is crucial.
Reduction in Digestive Discomfort
Nuts are known for causing bloating or indigestion in some people. Soaking facilitates easier digestion by reducing the natural enzyme inhibitors that interfere with digestive enzymes, such as amylase and pepsin.
Soaked vs Non-Soaked Walnuts: A Side-by-Side Comparison
To illustrate the difference between soaked and raw walnuts, let’s compare key factors:
| Aspect | Non-Soaked Walnuts | Soaked Walnuts |
|---|---|---|
| Nutrient Availability | Lower due to phytic acid | Higher due to reduced antinutrients |
| Digestibility | May cause bloating or discomfort | Improved due to enzyme activation |
| Texture | Crunchy, hard | Soft and tender if not dried, crisp if dehydrated |
| Flavor | Light and earthy | Richer and milder after soaking |
| Use in Dishes | Ideal for baking, toasts, salads | Better for snacking, blended recipes like nut milk, sauces, and desserts |
This comparison shows that soaking walnuts can make them more versatile, digestible, and nutritionally potent, making it a superior choice for health-conscious consumers.
Tips and Tricks for Soaking Walnuts Effectively
While soaking walnuts is simple, a few tips can help maximize the process and ensure the best results:
Use Quality Ingredients
Always start with organic, raw walnuts. They are less likely to have chemical coatings or rancid oils and typically have a better flavor and nutrient profile.
Soak in the Correct Water-to-Nut Ratio
Ensure walnuts are fully submerged but not swimming in excess water. A 4:1 water-to-nut ratio generally works best for activation.
Change the Water Every 6–8 Hours (for Extended Soaking)
If you’re soaking walnuts for longer than 12 hours and won’t be rinsing them, consider replacing the water halfway through to avoid mold formation and bacterial growth.
Store Properly After Soaking
If you’re not eating your soaked walnuts right away, store them in the refrigerator in a sealed container for up to a few days. For longer storage, dry them using a dehydrator and keep in an airtight jar in the freezer.

Why should I soak walnuts before eating them?
Soaking walnuts before consumption is a practice rooted in improving their nutritional availability and digestibility. Walnuts contain natural compounds such as phytic acid and enzyme inhibitors that can interfere with the absorption of essential minerals like iron, zinc, and calcium. Soaking helps to reduce these compounds, making the nutrients in walnuts more accessible to your body and enhancing their overall nutritional benefits.
Additionally, soaking softens the walnuts and can enhance their flavor and texture, making them more pleasant to eat. This simple process also activates enzymes that may aid digestion, helping your body break down and utilize the healthy fats, proteins, and other nutrients found in walnuts more effectively. For those looking to maximize the dietary benefits of walnuts, especially in raw food diets or smoothies, soaking is a valuable preparatory step.
How long should I soak walnuts for optimal results?
To get the best results from soaking walnuts, it’s recommended to soak them for at least 4 hours, although soaking them overnight (around 8 hours) is ideal. This allows enough time for the phytic acid and enzyme inhibitors to be naturally broken down and leached out into the soaking water. The longer soak also ensures the walnuts become fully hydrated, improving their digestibility and softening their sometimes bitter flavor.
It’s important not to over-soak walnuts, however, as leaving them for more than 12 hours can encourage the growth of bacteria or fermentation. If soaking overnight, place them in a bowl with enough filtered water to cover them completely and leave them at room temperature. If you’re in a hurry, a minimum of 2 hours may help, but the benefits will be somewhat reduced compared to longer soaking times.
Should I use salt when soaking walnuts?
While adding salt to the soaking water is not mandatory, it can be beneficial. Salt helps activate enzymes in the walnuts that assist in neutralizing phytic acid and enzyme inhibitors. Using about 1 tablespoon of sea salt or Himalayan salt per 4 cups of filtered water can enhance the nutrient availability and aid in the soaking process. This traditional method is commonly used with nuts, seeds, and grains to improve overall digestion and nutrient absorption.
That said, if you’re avoiding salt for dietary reasons or prefer not to use it, walnuts can still be soaked effectively in plain filtered water. The soaking process alone will still reduce phytates and improve digestibility. However, the addition of salt may contribute to even better results. Just be sure to rinse the walnuts thoroughly after soaking to remove any residual salt and bitterness from the surface.
Do I need to dry soaked walnuts before eating them?
Drying soaked walnuts is optional and largely depends on how you plan to consume them. You can eat them right after soaking, especially if you’re using them raw in smoothies, oatmeal, or yogurt. However, drying walnuts can help restore some of their natural crunch and extend their shelf life, making them more versatile for snacking or incorporating into baked goods and salads.
To dry soaked walnuts without cooking them, spread them evenly on a clean towel or a mesh dehydrator sheet and let them air dry at room temperature for 12 to 24 hours. Using a warm, dry place can speed up the process. Alternatively, use a dehydrator or oven on a very low heat setting (below 150°F or 65°C) to preserve enzymes and nutrients while achieving a crisp texture. Once dried, store them in an airtight container in the refrigerator or freezer to maintain freshness.
What happens if I don’t soak walnuts before consuming them?
Not soaking walnuts before consumption does not make them harmful, but it can affect how your body absorbs the nutrients they contain. Phytic acid is naturally present in walnuts and can bind to minerals in the digestive tract, reducing the body’s ability to absorb them. This can potentially lead to digestive discomfort or reduced nutrient intake over time, especially for individuals who regularly consume a diet high in nuts and seeds.
Additionally, walnuts that are not soaked may be harder to digest and can taste slightly bitter or chalky due to enzyme inhibitors and tannins present on their skin. While raw walnuts are still a healthy choice, skipping the soaking process may limit the body’s ability to fully reap the benefits of the healthy fats, proteins, antioxidants, and minerals found in them. For those with sensitive digestive systems, soaking can make a noticeable difference in comfort and nutritional uptake.
Can I soak walnuts and other nuts together?
Yes, you can soak walnuts with other nuts and seeds together, and this is a common practice for convenience and efficiency. However, different nuts have varying recommended soaking times; for example, almonds often require longer soaking (up to 12 hours) than walnuts. So, if soaking a mix, it’s best to use a standard soaking time of around 8 hours to accommodate most varieties without over-soaking any particular type. Make sure all nuts are fully submerged and that the water is sufficient to allow them to expand.
Another consideration when soaking multiple nuts together is salt. Adding salt to the soaking water helps with the breakdown of phytic acid across different nut types. Just be sure to rinse them thoroughly afterward to remove any tannins or debris from the skins. If possible, separate the nuts after soaking and drying for more tailored handling, especially if you’re drying them in an oven or dehydrator where you may want different drying times for different nuts.
How do I store soaked walnuts safely?
Proper storage is crucial to maintaining the freshness and quality of soaked walnuts. After soaking and rinsing, if you plan to use the walnuts within a few days, store them in an airtight container in the refrigerator. It’s also helpful to spread them out in a single layer on a clean towel or paper towel to dry slightly before refrigerating if you notice excess moisture, as this helps prevent mold and spoilage.
If you want to store soaked walnuts for a longer period, consider drying them thoroughly as described and then storing them in a sealed container or freezer bag in the freezer. Dried soaked walnuts can last up to a few months in the fridge and even longer in the freezer without losing their flavor or quality. Always check for rancidity or off smells before consuming, especially with long-stored nuts, due to the high oil content that makes walnuts prone to oxidation over time.
