What Are Walnuts Good For?

A quarter cup of walnuts offers you more than the recommended daily amounts of omega-3 fatty acids, which boost heart health and fight inflammation. The antioxidants in the nuts can aid cancer treatment as well. And the fiber in the nuts improves digestive health and aids weight loss. Well, these are just some of the benefits. There’s more.

What Are The Benefits Of Walnuts?

1. Aid Weight Loss

The omega-3 fatty acids in walnuts have been linked to a reduced risk of obesity. They also are rich in manganese and copper and another nutrient called ellagic acid – all of which boost metabolism. This can aid weight loss as well.

The fiber and protein in walnuts can make you less hungry and less likely to binge. Other studies also show how women who ate a handful of walnuts every day for six months lost about eight percent of their initial weight (1). Another report published in the Harvard Medical School states that walnuts activate a particular brain region that controls appetite and impulses (2).

2. Walnuts Boost Brain Health

Consuming walnuts as part of a diet can boost memory and brain function. The antioxidants in the nuts help prevent age-related cognitive decline and even reduce the risk of Alzheimer’s. And then, we have omega-3s in walnuts that also boost brain health and memory. Other nutrients in walnuts like vitamin E, folate, and melatonin are also known to enhance brain functioning.

Low omega-3 intake has also been linked to depression and anxiety, and these issues can be prevented by munching on a handful of walnuts every day.

3. Protect The Heart

Walnuts can lower bad cholesterol, and this protects the heart in the long run (3). And the omega-3 fatty acids in walnuts can prevent dangerous heart rhythms that might otherwise lead to heart attacks. Walnuts also have vitamin E, which can prevent plaque formation – eventually warding off coronary heart disease. The l-arginine in walnuts improves the health of the artery walls and makes them less prone to blood clots.

As per data analyzed by 210,000 health professionals over 32 years, people who ate nuts five or more times a week had 14% lower risk of cardiovascular disease (4).

4. Help In Diabetes Treatment

Benefits Of Walnuts - Help In Diabetes Treatment Pinit


Research concludes that patients who take 30 grams of walnuts every day for a year can reduce their fasting insulin levels as compared to those who don’t. The omega-3 fatty acids (alpha-linolenic acid) in walnuts can also improve diabetic neuropathy, a diabetes complication that damages nerves.

Other studies have also stated that women who take walnuts have a lower risk of type 2 diabetes (5). Some research has also found that walnuts can be the most effective amongst other nuts to lower blood glucose levels.

5. Fight Inflammatory Arthritis

Unlike other nuts, walnuts are specifically rich in omega-3 fatty acids. These fight inflammation and work wonderfully well in treating arthritis and joint pains. Adding walnuts to the diet can also reduce the levels of C-reactive protein, which is an inflammatory marker linked to arthritis (6).

Walnuts also promote bone health. They contain magnesium, which works along with calcium to build bones.

6. Improve Prostate Health

Numerous studies have spoken about the anti-prostate cancer effects of walnuts. Walnut intake can decrease IGF-1 (or insulin-like growth factor-1), which is a growth hormone linked to prostate cancer. And as walnuts also reduce cholesterol, the cancer cells are deprived of it and cannot grow as quickly. This makes the treatment easier.

Walnut intake also increases adiponectin and PSP94 – both of which are tumor suppressors. This also helps prevent prostate cancer.

7. Can Enhance Fertility And Sperm Health

Being a natural source of omega-3 fatty acids, walnuts can help the sperm mature and work properly (7).

8. Improves Digestion

Consumption of walnuts can increase the number of gut bacteria – they work as a prebiotic. Being packed with significant amounts of protein and fiber makes walnuts good digestive aids.

9. Regulate Sleep

Benefits Of Walnuts - Regulate Sleep Pinit


Walnuts contain melatonin, which promotes sleep. It is an important chemical in the body that regulates our internal clock (8). When it gets dark, melatonin levels increase in the body to make you fall asleep.

The fatty acid makeup of walnuts might also play a role in proper sleep.

10. Are Beneficial During Pregnancy

The omega-3 fatty acids and protein in walnuts help in the development of the newborn. And as they contain fiber, they help in weight management during pregnancy. Walnuts also contain copper that is known to promote fetus development.

As per a report by the Michigan State University, storing walnuts properly is important. The oil in the nuts might turn rancid if exposed to warm temperatures for long periods. Store the nuts safely in an airtight container in a cool and dry place (9).

11. Moisturize Skin And Boost Skin Health

The nutrients and healthy fats in walnuts attract moisture from the air and soothe dry skin. And the omega-3s can reduce skin inflammation as well.

And the protein in the nuts accelerates wound healing and prevents scar formation. The antioxidants protect the skin from the damaging free radicals and can even fight the signs of aging.

12. Boost Hair Growth

The omega-3 fatty acids in the walnuts get the credit again. They strengthen the hair follicles and prevent hair follicles. And the protein they contain also strengthens hair and boosts hair growth. Some sources say that walnut oil can help treat dandruff.

These are the benefits of walnuts – but we also need to know all the nutrients in these nuts that make them so great.
