If you’ve ever stood in the grocery store snack aisle staring at the nut bin, wondering if that small, crunchy bite is worth adding to your daily rotation, you’re not alone. I hear this question all the time—from regular customers grabbing a bag for their commute, from dietitians putting together client meal plans, from friends asking for the “healthiest” pick for their kid’s lunch. One of the most common questions I get, though, is this: Are nuts a good source of zinc? As someone who’s spent the last 12 years working in the nut industry, sourcing, processing, and selling high-quality nuts to people and businesses across the country, I’ve dug into this question more times than I can count, and I’ve got answers that go way beyond the vague “yes” or “no” you’ll find on a random food blog. Nut
First, let’s cut through the jargon about zinc—because I know a lot of this stuff can feel overwhelming. Zinc is a mineral your body needs for way more than just a strong immune system (though that’s the one everyone remembers). It supports wound healing, helps your body make DNA, plays a role in how your senses of taste and smell work, and even supports healthy growth and development for kids and teens. The National Institutes of Health (NIH) recommends adults get about 11 milligrams of zinc a day for men, 8 milligrams for women, and a little more for pregnant or breastfeeding folks. The problem is, a lot of people don’t hit that mark. A 2021 study from the Centers for Disease Control and Prevention (CDC) found that around 12% of the U.S. population isn’t getting enough zinc from their diet, and that number jumps to almost 20% for certain groups, like older adults and vegans or vegetarians.
So where do people usually get zinc? The most common answer is red meat, poultry, and seafood—oysters are even famous for being high in zinc. But if you’re cutting back on animal products, or you’re just looking for plant-based options that are easy to add to your day, nuts are a standout. But wait—before you go dumping a whole bag of almonds into your salad, there’s a key detail I want to share: not all nuts are created equal when it comes to zinc. I make it a point to test every batch of nuts we source for zinc content (it’s part of our third-party quality checks) because knowing which nuts deliver the most zinc per serving is half the battle.
Let’s break down the numbers, straight from the USDA FoodData Central, which is the gold standard for nutrition information: a 1-ounce (28-gram) serving of cashews has about 1.65 milligrams of zinc. That’s almost 21% of the daily recommended amount for women, and 15% for men. Next on the list are pine nuts, with around 1.38 milligrams per ounce, followed by peanuts (yes, peanuts are legumes, but most people group them with nuts for snacking purposes) at 0.9 milligrams, and almonds at 0.6 milligrams per ounce. Pistachios clock in at about 1.47 milligrams per ounce, too—fun fact, we actually get a lot of requests for bulk pistachios from schools and cafeterias because they’re affordable, kid-friendly, and pack a solid zinc punch.
Wait a second—those numbers might seem low compared to a 3-ounce serving of beef, which has about 7 milligrams of zinc. But here’s the thing I always tell my customers: you don’t get your entire daily zinc requirement from one food. It adds up over the course of the day, and nuts have other benefits that make their zinc contribution way more valuable than it might seem at first glance. Let’s talk about those other nutrients, because that’s the big picture most people miss when they’re only focused on zinc. Nuts aren’t just a zinc source—they’re packed with protein, fiber, healthy fats, vitamin E, magnesium, and antioxidants. A 2019 study published in the Journal of Nutrition found that people who ate at least one ounce of nuts a day had higher overall nutrient intake, including zinc, than those who rarely ate nuts, because nut eaters tend to have more balanced diets overall.
But there’s a catch here that I learned early on in my career, working with our quality control team: phytic acid. Phytic acid is a compound found in many plant foods, including nuts, that binds to minerals like zinc and iron, making them harder for your body to absorb. That’s not to say nuts are a bad zinc source—far from it—but if you’re relying solely on nuts to hit your zinc goals, there are small steps you can take to boost that absorption. For example, soaking nuts in water overnight before eating them can reduce phytic acid levels by up to 50%, which makes the zinc more bioavailable. We actually recommend this to our bulk nut clients who sell to health food stores and bakeries; soaked nuts are a popular ingredient in granola bars and trail mixes because they’re easier on digestion and their nutrients are more accessible. Roasting nuts at moderate temperatures (around 300°F) also breaks down some phytic acid, which is why our roasted cashews, for example, have a slightly higher zinc absorption rate than raw cashews, according to internal data from testing we did with a local university’s nutrition department a few years back.
I also want to address a common misconception I hear all the time from people following plant-based diets: that plant-based zinc is “inferior” to animal-based zinc. While it’s true that animal-based zinc has a higher absorption rate (around 30-40%, compared to 10-20% for plant-based), that doesn’t mean plant-based zinc isn’t worth including. Adding a source of vitamin C to a meal that includes nuts—like a handful of cashews with an orange, or almond butter on toast with a side of strawberries—can drastically boost zinc absorption. I make it a point to post these little pairings on our social media pages, because so many people don’t know that simple trick. For example, a serving of cashews with a small orange gives you 1.65 milligrams of zinc and 70 milligrams of vitamin C, which increases zinc absorption by about 50%. That turns a moderate zinc source into a highly absorbable one, no animal products required.
Let’s talk about who can really benefit from adding nuts to their diet for zinc. Older adults, for one: as people age, their appetite often decreases, making it harder to get enough zinc from large meals, and zinc deficiency in older adults is linked to weaker immune function and slower wound healing. Nuts are small, portable, and easy to add to oatmeal, yogurt, or salads, so they’re a perfect snack for someone who might struggle to eat large portions. Vegans and vegetarians, too—since animal products are the primary zinc source for many people, plant-based eaters need to be intentional about including zinc-rich foods, and nuts are one of the most convenient options I’ve found. I work with a lot of local plant-based cafes that source our bulk cashews and almonds specifically for this reason; they add them to their grain bowls and smoothies to make sure their customers are getting enough zinc. Even kids—who often have small appetites and might not eat enough nutrient-dense foods—love nuts as a crunchy, tasty snack, and a ½-ounce serving of pistachios (about 15 kernels) has almost 0.75 milligrams of zinc, which is a great addition to their school lunch.
Now, I want to be honest and transparent about something: zinc content can vary depending on how nuts are grown, processed, and stored. That’s why we’re so careful about our supply chain. We source our nuts from family farms across the U.S. and parts of Central and South America, working directly with farmers who use sustainable growing practices that support soil health—because healthy soil means nutrient-rich nuts. We test every incoming batch for zinc and other nutrients, and we avoid adding any unnecessary fillers or preservatives that could affect nutrient levels. I’ve seen what happens when nuts are stored improperly, too: if they’re kept in warm, humid conditions for too long, they can go rancid, and that process breaks down many of the vitamins and minerals, including zinc. That’s why we store our nuts in climate-controlled facilities, and we recommend our customers keep their nuts in airtight containers in a cool, dark place to preserve their nutritional value.
I also get asked all the time: How much nuts should I eat to get enough zinc? The answer depends on your overall diet, but as a general rule, adding 1 to 2 ounces of zinc-rich nuts a day is a great start. For example, if you eat 1 ounce of cashews (1.65 mg zinc) and ½ ounce of peanuts (0.45 mg zinc), that’s over 2 mg of zinc from nuts alone, which is a solid chunk of your daily requirement, especially when paired with other zinc-rich foods like legumes, whole grains, or dairy. That’s also about the amount of nuts recommended by the USDA’s MyPlate guidelines for a balanced diet—so it fits right in with general healthy eating advice, not just zinc goals.
At the end of the day, when someone asks me if nuts are a good source of zinc, my answer is a resounding yes—but with context. They’re not the highest zinc source you can eat, but they’re convenient, versatile, packed with other nutrients, and easy to fit into almost any diet. For people looking for plant-based zinc, or for anyone who wants a portable, tasty way to boost their zinc intake throughout the day, nuts are an excellent option.
