How to Store Walnuts?

When storing walnuts, there are a few key things to remember. First, keep the nuts in an airtight container. Secondly, store them away from strong odors. You also don’t want to leave them on the ground for long periods of time. After all, you don’t want them to become moldy or go bad.

When buying walnuts, make sure that you shell them first. Doing so will improve the taste. This way, the nuts will be less likely to lose their freshness over time. Unshelled walnuts can be stored for up to six months in the refrigerator, and up to a year in the freezer. Walnuts are rich in vitamins B-5, B-6, and riboflavin, as well as minerals. They are also considered fruits, meaning they do not have much fat in them.


How Do Walnuts Work?

The walnut tree produces walnuts, which are round, single-seeded stone fruits. They include a lot of fiber, protein, and heart-healthy lipids. Among other things, they could help with weight loss and heart and bone health. However, they are also commonly planted in China, Iran, California, and Arizona in the United States. Walnut trees are native to eastern North America. Behind the husk of the walnut, fruit is a wrinkly, globe-shaped nut. The walnut is split into two flat halves before being advertised for sale. Walnuts can be bought salted or unsalted, raw or roasted. The nutritional content of walnuts and any potential health advantages are examined in this article.

How to Store Walnuts

Walnuts should be carefully stored in an airtight container in a cold, dry area, whether they are shelled or not. Walnuts can be stored in the refrigerator for up to three months without losing any of their freshness. Walnuts can also be frozen for up to a year.

As walnuts absorb smells, it is better to keep them away from foods like onions and other strong-smelling dishes. The best protection to keep food fresh is in airtight containers. It is preferable to put the walnuts you buy in bulk into airtight containers when you arrive home.

Walnuts can be found year-round at food shops, although they are most visible from August through November when they are in season. Although California claims to produce 99 percent of the walnuts consumed in the United States, black walnuts grown locally are also available in Michigan.

Walnuts are a great addition to your family’s grocery list because proper storage is simple, helps to preserve their delicious, crisp taste, and has health advantages.

What Are Walnuts’ Health Advantages?

To say that walnuts are a nutrient-dense food is an understatement. Walnuts are rich in fiber, vitamins, minerals, healthy fats, and fiber, but that is just the beginning of how they can benefit your overall health. In fact, there is so much interest in this particular nut that for the past 50 years, researchers and business leaders have convened at the University of California, Davis, for a conference on walnut health to discuss the most recent studies. The most well-known and researched walnut variety is the English walnut.

Here are some scientifically validated health advantages of walnuts.

Antioxidants Abundant

More antioxidants than any other common nut may be found in walnuts. This effect is brought on by polyphenols, which are particularly plentiful in the papery skin of walnuts and include vitamin E, melatonin, and plant compounds.

According to a tiny preliminary study on healthy people, eating a dinner high in refined fats did not lower the oxidative damage of “bad” LDL cholesterol after eating, while eating a meal high in walnuts did. This is important since oxidized LDL can cause atherosclerosis by forming plaque in your arteries.

Omega-3 Super Plant Source

With 2.5 grams per 1-ounce (28-gram) serving, walnuts have the highest omega-3 fat content of any nut.

An omega-3 lipid called alpha-linolenic acid is present in plants, particularly walnuts (ALA). Since it is a necessary fat, you must consume food to get it.

A single serving of walnuts satisfies the Institute of Medicine’s recommendation that men and women consume 1.6 and 1.1 grams of ALA each day, respectively. Observational studies have shown that every gram of ALA ingested daily lowers your risk of dying from heart disease by 10%.

Might Reduce Inflammation

Inflammation is a major factor in the development of many diseases, including heart disease, type 2 diabetes, Alzheimer’s disease, and cancer. Oxidative stress has the ability to generate inflammation. Walnut polyphenols may help in the fight against inflammation and oxidative damage.

A subtype of polyphenols called ellagitannins may be the main culprit. Ellagitannins are transformed into anti-inflammatory urolithins by helpful microorganisms in your gut. Magnesium, the amino acid arginine, and the ALA omega-3 oil found in walnuts may also assist to lessen inflammation.

Encourages Gut Health

Your chances of having a healthy gut and general health are increased, according to studies, if your gut microbiota is populated with bacteria and other microorganisms that promote health. An unbalanced microbiota composition can lead to disease and inflammation in your gut and other regions of your body, increasing your chances of being obese, developing heart disease, and developing cancer.

Your microbiota’s makeup is significantly influenced by what you eat. Eating walnuts is one way to improve the health of your microbiota and gut. Over the course of eight weeks, 194 healthy individuals consumed 1.5 ounces (43 grams) of walnuts daily, and this led to an increase in the number of good bacteria in their guts compared to the control group.

May Lower the Risk of Some Cancers

Walnuts may lower the risk of several cancers, including breast, prostate, and colorectal cancers, according to test-tube, animal, and human observational studies. Walnuts contain a lot of polyphenol ellagitannins, which can be changed into urolithins by particular gut bacteria, as was already mentioned.

Which is Healthier for You, Walnuts or Cashews?

If you’re looking for a nutrient-dense, heart-healthy snack, should you eat cashews or walnuts? Both of these nuts taste great because many people like to research the nutritional content of foods before choosing which ones to eat. Walnuts and cashews both provide a lot of health benefits when you examine their nutritional profiles.

There is no one-size-fits-all method for choosing the healthiest nut, despite the importance of considering the macros and nutrients you are getting from your meal. The best way to receive different vitamins and minerals, according to many nutritionists, is to consume a variety of nuts, seeds, fruits, and vegetables.

Food that is convenient and scrumptious is what Nature’s Garden is committed to providing for your family.

Benefits of Walnuts vs. Cashews

When contrasting the nutritional value of cashews with walnuts, you should be aware of the following:

Macronutrients: Many people enjoy keeping track of their calorie, protein, fat, and carb intake. Compared to walnuts, cashews have fewer calories, but they also have more protein and less fat.

Micronutrients: In addition to looking at macronutrients like protein, fat, and carbohydrates, it’s also important to consider micronutrients like the vitamins and minerals you get from these nuts. Walnuts are higher in magnesium, zinc, iron, copper, and phosphorus as well as several micronutrients like vitamin E, omega-3 fatty acids, manganese, and cashews.

Allergies to tree nuts: You also need to think about whether you’re allergic to cashews or walnuts. If you are aware that you are allergic to tree nuts, you should avoid these nuts since they are classified as “tree nuts.” To boost your health, you can choose from a variety of different seeds and high-protein snacks.

What Negative Effects Can Walnuts Have?

Having walnuts can also have the following negative effects:

One of the top eight allergenic foods is walnuts. Walnut allergies frequently result in serious symptoms, such as allergic shock (anaphylaxis), which can be fatal if untreated. You must stay away from walnuts if you are allergic to them.

Like other seeds, walnuts have a lot of phytic acids. A component of plants called phytate, also known as phytic acid, prevents the body from absorbing nutrients from the digestive system like iron and zinc. This only applies to meals, which may include phytate-rich foods.

Individuals who consume an unbalanced diet high in phytic acid are more prone to experience mineral deficiencies, but the majority of people shouldn’t be alarmed.

Despite their nutritional value, some people must avoid walnuts due to allergies. Phytic acid may hinder the absorption of minerals, however, this normally isn’t a problem for those who eat a healthy, balanced diet.

How to Tell Walnuts are Bad?

Walnuts can turn out poorly. By looking at a few simple signs, we may tell whether walnuts are great or awful quickly:

The walnut shell shouldn’t dry out or shrink, and it should be intact. If the shell appears unhealthy, throw it away. You can check to see whether the nut has failed or if you see a rusty ring.

Check to see whether the nut has a bad smell or is discolored. Throw it away if it smells bad or shows signs of rust.

If a walnut’s shell is dark brown, you can test the kernel’s quality by soaking it in water.

If you notice a fungus or mold on the surface, it is probably stale. This indicates that the walnut is subpar.

The oil will become harsh and unusable after it has gone rancid.

Numerous tests can let some walnuts get through undetected. This is bad since, if not thrown out, these things can ruin a dinner.

If you’re doubtful, give them a sniff. You should always throw away the stale walnuts because they will smell harsh and not be palatable.

A high-quality walnut won’t taste rotten and will have a mild, nutty flavor. A bitter-smelling walnut, though, is probably not a wise decision.

Walnuts occasionally go bad. Dark marks on them indicate that they have made mistakes. These walnuts will not be fresh and have a bitter flavor. When is the ideal moment to discard them?

The shell is one indication of badness, and if they are oily, they are probably too old to eat, which is a positive sign that they are safe to eat.

You should examine walnuts to determine whether they are incorrect. You should look for wormholes, shrinkage, and mold. Additionally, you should smell them to see whether they have gone bad.


When storing walnuts, be sure to keep them in a dark, low-humid area. The unshelled ones last for up to four months in the pantry, but they won’t last as long. Similarly, shelled walnuts can last for up to two months in the refrigerator. The best way to store your nuts is to keep them in the refrigerator instead of the pantry. They’ll keep longer in the refrigerator if stored in an airtight container.

One of the most important tips for storing walnuts is to use airtight containers. This will help them remain fresh and free from outside odors. Walnuts absorb odors and flavors from nearby food items, so storing them in an airtight container will prevent the spread of these smells.
