Recommended daily serving of nuts

The recommended daily serving of nuts can vary based on individual dietary needs and goals, as well as the type of nut. Nuts are energy-dense foods, meaning they provide a significant number of calories per serving due to their healthy fat content. While nuts offer numerous health benefits, portion control is important to avoid excessive calorie intake.

As a general guideline, a portion of nuts is typically around 1 ounce, which is roughly equivalent to:

About 23 almonds

About 14 walnut halves

About 18 cashews

About 49 pistachios in the shell, or 28 pistachios without shells

About 9 Brazil nuts

About 19 pecan halves

About 10-12 macadamia nuts

Nut Warnings: Understanding Allergies and Precautions

Nuts and Allergens: Nuts such as peanuts, tree nuts (like almonds, walnuts, cashews, and pistachios), and even seeds like sesame can contain proteins that trigger allergic reactions in certain individuals.

Symptoms of Nut Allergies: Nut allergies can lead to symptoms such as hives, itching, swelling, wheezing, difficulty breathing, and anaphylaxis—an acute, life-threatening allergic reaction.

Reading Labels: Always read food labels carefully to identify potential nut or nut-derived ingredients. Manufacturers are required to list common allergens on their labels.

Communicating Allergies: Inform restaurants, food servers, and anyone preparing your food about your nut allergy. Being proactive can help prevent accidental exposure.

Epinephrine Auto-Injector: Individuals with severe nut allergies are often prescribed an epinephrine auto-injector (EpiPen) that can be used in case of anaphylactic reactions. Knowing how to use it is crucial.

Baked Goods and Restaurants: Be cautious with baked goods, candies, sauces, and ethnic dishes, as these can often contain nuts or nut derivatives.

How should nuts and seeds be stored?

Storing nuts and seeds properly is essential to maintain their freshness and prevent them from becoming rancid. Here are some tips for storing nuts and seeds:

1. Cool and Dry Location: Store nuts and seeds in a cool, dry place away from direct sunlight and heat sources. Excessive heat and light can cause the natural oils in nuts and seeds to go rancid and affect their taste and nutritional quality.

2. Airtight Containers: Transfer nuts and seeds to airtight containers to protect them from exposure to air, which can lead to oxidation and spoilage. Mason jars, resealable bags, or food storage containers with tight-fitting lids are good options.

3. Refrigeration: For longer storage, you can refrigerate nuts and seeds, especially if you live in a warm and humid climate. Place them in an airtight container to prevent moisture from getting in and causing them to become soggy.

4. Freezing: Freezing nuts and seeds can significantly extend their shelf life. Place them in an airtight container or resealable bag and remove as much air as possible before freezing. When you’re ready to use them, you can thaw them at room temperature or use them directly from the freezer in recipes.

5. Vacuum Sealing: Vacuum sealing nuts and seeds can remove excess air and help preserve their freshness. Vacuum-sealed bags can be stored in the pantry, fridge, or freezer.

6. Labeling: If you buy nuts and seeds in bulk and transfer them to different containers, it’s a good idea to label them with the purchase date. This helps you keep track of their freshness and usage.

7. Rotate Stock: Nuts and seeds have a limited shelf life due to their natural oils. To ensure you’re consuming them at their best quality, try to rotate your stock and use older items before newer ones.

8. Avoid Moisture: Moisture can lead to mold growth and spoilage. Make sure your storage containers are completely dry before adding nuts and seeds, and avoid storing them in humid environments.

9. Shell-on vs. Shelled: If you have nuts with shells, such as walnuts or pistachios, it’s best to keep them in their shells until you’re ready to consume them. This helps protect the nuts inside from exposure to air and moisture.

10. Buy in Smaller Quantities: If you don’t use nuts and seeds frequently, consider buying them in smaller quantities to ensure you’re using them while they’re still fresh.

Can nuts and seeds be consumed by children?

Yes, nuts and seeds can be consumed by children, but there are a few important considerations to keep in mind to ensure their safety and suitability for different age groups:

1. Choking Hazard: Whole nuts and seeds can pose a choking hazard, especially for young children. It’s recommended to avoid giving whole nuts or seeds to children under the age of 4, as their airways are smaller and more susceptible to blockage. Instead, offer nuts and seeds in a safe form, such as ground or finely chopped.

2. Allergies: Nuts and seeds are common allergens, and allergies can develop at any age. It’s important to introduce nuts and seeds cautiously, especially if you have a family history of allergies. Introduce one type of nut or seed at a time and watch for any signs of allergic reactions like hives, swelling, difficulty breathing, or digestive discomfort. Consult with a pediatrician if you’re unsure about when and how to introduce nuts and seeds.

3. Nut Butter: Nut butters (such as peanut butter, almond butter, and cashew butter) can be a good option for children. However, spread nut butter thinly on toast, crackers, or fruit to reduce the risk of choking. Always choose natural nut butters without added sugars or hydrogenated oils.

4. Seeds: Small seeds like chia seeds and flaxseeds can be included in a child’s diet, but they should be used in moderation and preferably soaked or ground before consumption. This helps enhance digestibility and nutrient absorption.


Nuts and seeds stand as nutritional powerhouses that contribute to heart health, brain function, weight management, bone health, and more. Their diverse nutrient profiles and versatility make them valuable additions to a balanced diet. However, as with any dietary component, moderation is key. Including a variety of nuts and seeds in your diet can offer a wide spectrum of health benefits, but be mindful of portion sizes to avoid excessive calorie intake. Whether enjoyed as a snack, added to meals, or used in cooking and baking, nuts and seeds are indeed nature’s treasures that can play a vital role in promoting your overall well-being.
