Health Benefits of Eating Walnuts
Eating plant-based foods has long been associated with a shortened risk of many lifestyle-related health conditions.
The possible health benefits of walnuts may involve boosting the cardiovascular system & bone health, reducing the risk of gallbladder disease & treating epilepsy.
Heart Health
The monounsaturated & polyunsaturated fatty acids found in walnuts decrease LDL (harmful) cholesterol & triglyceride levels. This, in turn, reduces the risk of cardiovascular disease, stroke & heart attack.
Lower Blood Pressure
Â
Eating walnuts may contribute to lowering blood pressure, both in individuals with high blood pressure & in those under stress who have high blood pressure.

Walnuts contain nutrients that help protect your brain from damaging inflammation & support good brain function as you age.
Improves Blood Fats
You may reduce your heart disease risk by consuming 1.5 ounces (43 grams) of walnuts daily.

How many Walnuts should you eat?
Eat 7-10 walnuts a day.
Walnuts in the Diet
Nuts have a high-fat content & so they are prone to becoming rancid. Rancid nuts are not unsafe but have a sharp flavor that people may find unpleasant.
Keeping Walnuts in their shells in a dark, cool & dry place can improve their shelf life.
When you keep walnuts in a refrigerator below 40 degrees Fahrenheit or a freezer below 0 degrees Fahrenheit, they can be stored for over a year.
You can freeze them at 0 degrees Fahrenheit or less for 48 hours if you want to store them at room temperature.
The following are some easy & delicious ways to eat more walnuts:
- Make a pesto sauce using walnuts & use it with pasta or flatbread
- Top yogurt with chopped walnuts & fruit
- Top salads with chopped walnuts
- Make homemade granola with a mixture of nuts, seeds & dried fruit, using walnuts.
The Dietary Approaches to Stop Hypertension diet–known as the DASH diet–is an eating program developed through research sponsored by the U.S. National Institute of Health (NIH) aimed at reducing blood pressure and cholesterol.
It includes eating fruits and vegetables, low-fat or non-fat dairy, nuts (including walnuts), and whole grains. It contains high fiber and low to moderate fat and is rich in potassium, calcium, and magnesium.
Recent DASH studies have shown the benefits of lowering sodium intake on blood pressure. Not only have studies shown that eating walnuts are associated with improved blood pressure and cholesterol levels, but walnuts also are naturally sodium-free and thus are perfect food for those following the DASH diet guidelines.
You can sprinkle them on a salad, eat them with your favorite fruits, blend them into a smoothie, or eat them plain.
As nutritious as walnuts are, you don’t need lots of them to reap the benefits.
Too much consumption has been associated with gastrointestinal discomfort, allergic reactions, and high-calorie intake, causing weight gain.
You can gain weight, soften your stools & experience bloating when you eat the nut.
When It’s Best
Walnuts generally don’t have a season, although walnut tree harvesting usually occurs between September and early November.
But since walnuts travel well & have a long shelf life, you can find them year-round in most markets.
When you choose walnuts, make sure you select an unsalted version. Too much sodium can increase blood pressure & cause bloating. Walnuts should smell mildly nutty & taste sweet.
Warning: If they smell like paint thinner, they have gone rancid & should be discarded.
Storage and Food Safety of Walnuts
For maximum shelf life, store walnuts in an airtight container in the freezer, depending on when you plan on using them.
Keeping walnuts cold can prevent them from going rancid. Walnuts that you store in the freezer should be kept away from foods with strong odors, such as onions, fish, or garlic, as walnuts can absorb the flavors of other foods.
If you plan on grinding your walnuts to use as a walnut meal, wait until you are ready to use them in your recipe to maintain the best flavor.
Varieties of Walnuts
The most common walnuts are English Walnuts, Persian walnuts & black walnuts, which may be available in some areas.
English walnuts are grown in the United States, Iran, China & turkey. California walnut growers produce 99% of the English walnuts consumed in the U.S & according to some reports, there are over 37 varieties of English walnuts available from growers in that area.
However, each has the same distinctive brown oval shell & light brown kernel. Lastly, you will find both roasted & raw walnuts at your local grocer.
Side effects & Allergies of Walnuts
Â
As is the case with most nuts, walnuts are known allergens. Therefore, people susceptible to allergies or who have nut allergies should get advice from the doctor before adding these nuts to their daily diet.
These allergies can range from mild to severe, with rashes, eczema, itchiness & even breathing difficulties as symptoms.
The Final Words
Eat them sparingly and make them a habit.
