Why You Should Never Eat Almonds Without Soaking Them First, According to a Gastroenterologist

18 December 2025

Before you reach for that handful of fresh, whole almonds and crunch away, stop right there! There’s a mighty reason you should grant your almonds a relaxing bath first. Yes, we’re talking about soaking them in water—a surprisingly simple habit with big implications for your well-being, according to gastroenterologist William Berrebi. Let’s unravel why this step makes all the difference for your digestion and how you can easily make it a part of your daily routine.

Why Almonds Need a Good Soak

When we’re busy in the kitchen, rinsing fruits and vegetables under the tap is second nature. But dry foods like almonds? Admittedly, they rarely get the same spa treatment. Yet, it turns out skipping this step is a mistake if you want to truly profit from everything a humble almond has to offer. As gastroenterologist William Berrebi reveals, soaking almonds in water before eating them is not just a suggestion—it’s a must for both digestion and absorption of nutrients.

Without soaking, almonds are hard to digest.
You also miss out on their full nutritional benefits.

Berrebi highlights a hidden culprit: almonds contain an enzyme inhibitor called phytic acid. This compound is, in his words, “a kind of anti-nutrient”: it impedes proper digestion and blocks the body from absorbing some essential nutrients. So, chewing your way through those dry, natural almonds can make it harder for your stomach and your body to truly reap what the almond sows.

The Magic Behind Soaking: Nutritional Upgrade

Okay, so you’re convinced your almonds need a soak. But what actually happens in that bowl overnight?

According to William Berrebi, soaking almonds triggers the first stage of germination. This is not just plant magic—but nutrition science in action. Once this process begins, the almonds’ nutritional profile starts to change for the better:

Vitamin content increases: Soaked almonds pack a bigger punch of vitamins for your system.
Protein levels multiply: Yes, you get more out of each nut!
Minerals become more absorbable: Your body can now access those minerals much more easily.

As a result, the almonds’ health benefits get a solid boost. It’s like switching from economy to first class—but only if you remember to toss them in water overnight.

How to Soak Almonds: The Simple Steps

Ready to put this gastroenterologist insight into practice? Fear not, the process couldn’t be simpler. William Berrebi lays out exactly how to ensure your almonds emerge digestion-friendly and more nutritious:

Start with a handful of almonds in a bowl.
Rinse thoroughly, then add drinkable water until the almonds are fully submerged.
Leave the bowl to rest overnight. (If only all healthy habits required so little effort.)
In the morning, drain and rinse the almonds well.
Time to enjoy—the almonds are now ready for you to munch away immediately after rinsing!

That’s really all there is to it. An extra few minutes of prep time in exchange for easier digestion and maximum nut power—that’s a trade most of us can live with.

Does This Apply to Other Seeds and Nuts?

If you’re now eyeing your pantry and wondering about the other residents—walnuts, sunflower seeds, pumpkin seeds—the answer is a cautious yes. Berrebi recommends soaking these as well, since they too contain phytic acid. The same process applies, so your morning routine might just see a few more bowls soaking on the counter!

Final Thoughts
So, next time you buy those tempting, shiny almonds, remember their secret: a soak is what unlocks their real potential. If you want better digestion and the full suite of nutrients, trust this advice from a gastroenterologist. Set a bowl tonight, give those almonds—and maybe their nutty friends—a swim, and experience the difference at snack time. Your stomach (and your taste buds) will thank you!
