When you cook with walnuts, you typically won’t use the whole bag. You can either eat the rest for their health benefits or store them until the next recipe calls for them. While walnuts do have a decent shelf life, is there a way to extend it?
Can you freeze walnuts to increase their shelf life?
Walnuts can be frozen in and out of their shell. Walnuts absorb other odors and will in turn taste like the odor they absorb as well. Store your walnuts in an airtight container to protect them from any potential odors.
Walnuts will be good for up to a year in the freezer. Unshelled and shelled walnuts should be stored the same way, in an airtight container. Your walnuts will retain their flavor when frozen whole, not ground or chopped.
The best way to defrost walnuts when you are ready for them is by placing them in the fridge. When walnuts are exposed to warm temperatures for an extended period, they will begin to go bad.

Can Eating Too Many Walnuts Be Harmful?
Everyone knows that if you eat too much candy, you will end up with a stomach ache. What about something healthy like nuts? Is there a problem with eating too many walnuts?
Since they are full of healthy benefits, is it harmful to eat too many walnuts?
Eating too much of anything is never good for your body. While walnuts may aid in weight loss, eating too many can lead to weight gain.

Are Walnuts Healthy?
Walnuts are a very nutritious food. Are there any health benefits from eating walnuts? If there are benefits from eating walnuts, is there a certain amount of walnuts you need to eat to experience these health benefits?
Walnuts are healthy when eaten in moderation. To receive the full benefits of walnuts, it is best to eat two to three ounces of walnuts a day.
Here are a few of the health benefits you might experience by eating the recommended amount of walnuts.
Walnuts Are Rich In Antioxidants
Antioxidants help your body fight against free radical cells. These free radical cells are the cause of heart disease, cancer, and other diseases.
You are typically exposed to free radicals when breaking down food in the digestion stage or when you are exposed to tobacco smoke. Walnuts provide the antioxidants needed to fight off these free radicals.
Walnuts Are A Great Source Of Omega-3’s.
Our bodies need Omega-3 fatty acids to support our hearts. This vitamin lowers inflammation in the blood vessels of your heart. It can make abnormal heart rhythms happen less often.
Omega-3’s can also slow the build-up of plaque that can happen in your heart. A serving of walnuts is a great way to add Omega-3’s to your diet.
Walnuts Can Potentially Decrease Inflammation
Inflammation is more than something that happens in your joints. Inflammation is the root of many diseases including heart disease, Alzheimer’s, type 2 diabetes, and many others.
This inflammation can be caused by oxidative stress. Walnuts fight oxidative stress and inflammation.
Walnuts Can Promote A Healthy Gut
A healthy gut is the key to good overall health. Eating walnuts help support the microbiota in your gut. An unhealthy gut can lead to obesity, heart disease, IBS, and other issues.
When you add walnuts to your diet, you promote the growth of healthy bacteria in your gut.
Walnuts Support Brain Function
Studies have shown that eating walnuts can help your brain function better with faster processing speed. It can also help promote better memory as well. The polyunsaturated fat and vitamin E found in walnuts are the key to promoting excellent brain health.
Walnuts Can Aid In Weight Management Or Weight Loss
While walnuts may be a bit higher in calories than other nuts, they do still aid in weight management and weight loss. Walnuts will not only help you feel full faster but also promote the brain function to resist tempting foods as well.
Do Packaged Walnuts Expire?
Nuts are one of those foods that seem to last forever and rarely go bad. With most foods, you can tell by looking at it or smelling it whether or not it has gone bad. However, with nuts, the signs are much more subtle.
It is often too late to know if the nuts have gone bad until you have taken a bite. Do walnuts have an expiration date? If they do, how do you know that they have gone bad?
Walnuts will go bad because of the oil that is inside them. After a while, the oil will go bad giving the walnuts a bitter taste.
Walnuts still inside their shell will last quite a while longer than unshelled walnuts. Shelled walnuts can last for a year or more. Unshelled walnuts will last for close to three months.
You can make unshelled walnuts last closer to a year when you place them in the freezer.
If your walnuts are still in their shell, the best way to tell if they have gone is just by looking at them. The shell will be shrunk and shriveled. There may also be dark spots on the shell and the nut itself, this is a sign of mold growth.
Since the oil in the walnut has started to go bad, the walnut might give off a different odor, like paint thinner. Another way to tell if a walnut is bad is by taste.
A bad walnut will taste very bitter. If you do happen to bite down on a bad walnut, be sure to spit it out right away and rinse out your mouth to remove the bitter taste.
Whether you plan on using walnuts for baking or consuming, the best way to ensure long shelf life is by keeping them stored in a cool place.
You can enjoy the many health benefits of walnuts by eating two to three ounces of walnuts a day. That averages out to about seven whole walnuts.
Be sure not to overeat walnuts as that could potentially cause weight gain and digestive issues.
