Walnuts Protect The Brain From Oxidative Stress

Why does walnut is good for brain, pregnancy, and insomnia? -health benefits of walnut

Walnuts are good for brain health, due to their high antioxidant content. Firstly, omega-3s have powerful antioxidant properties. Studies have shown that omega-3s can fight effectively oxidative stress and inflammation. Both are common causes of cognitive decline!

Furthermore, walnuts are particularly high in polyphenolic compounds. Potent antioxidants, as well. Actually, walnuts contain more polyphenolic compounds than any other nut. Therefore, eating walnuts regularly is important for good brain function.

On the other hand, bad diet, smoking, environmental pollution, and land lack of exercise are common causes that increase the risk of cognitive decline. Certainly, prevention is the key. A healthy diet could help. For instance, a whole food plant-based diet is rich in antioxidant and anti-inflammatory phytochemicals. These compounds are important for good brain health, as they:

  • reduce the oxidant and inflammatory load on brain cells,
  • improve interneuronal signaling,
  • increase neurogenesis.

Eating foods high in antioxidants is vital for the brain, as the brain is particularly vulnerable to oxidative stress! The brain consumes about 20% of the total body intake of oxygen. It has extreme energy requirements. On the other hand, the brain has limited antioxidant capacity. Therefore, eating walnuts and other foods rich in antioxidants is necessary for good brain health.

Why Eating Walnuts Is Good For Brain Health

Research suggests that eating walnuts may be one of the best things you can do to ensure long term brain health. Oddly enough, there have even been studies conducted that show diet plays a huge role in preventing various neurodegenerative diseases such as antioxidants, and anti-inflammatory phytochemicals. English walnuts are one of the richest foods in terms of phytochemicals and they also contain high contents of polyunsaturated fatty acids which could help maintain a healthy brain as you age.

The great thing about walnuts is that not only will they help your brain, but they are reasonably priced a food item that most people can afford. Listed below are various brain benefits associated with eating walnuts.

A Few Walnuts A Day May Help Boost Memory Study Finds

Go ahead, reach for those walnuts. A new study suggests that eating a handful of walnuts per day — or even less — may help boost memory, concentration and the speed at which your brain processes information.

In a cross-sectional study that drew from a sampling of thousands of people in the United States aged 20 and older, those who ate more walnuts performed better on a series of six cognitive tests, according to new research from the David Geffen School of Medicine at The University of California, Los Angeles, led by Dr. Lenore Arab. And cognitive function was consistently better no matter the person’s age, gender or ethnicity. The findings add to a growing body of research surrounding walnuts’ benefits on brain health.

In a press release, Arab said it was exciting to see the strength of evidence from an analysis across the U.S. population and involving a realistic amount of walnuts — less than a handful per day.

“It isn’t every day that research results in such simple advice — eating a handful of walnuts daily as a snack, or as part of a meal, can help improve your cognitive health,” she said.

Mechanistic Animal Studies Supporting Walnut Effects On Cognitive Function

In an effort to determine the bioavailability of FAs in the diet, at the site of action, rats fed diets containing 15% LA and 3% ALA were examined for whole-body distribution of deuterated LA and ALA after a single-dose oral administration . The brain concentration of LA peaked at 8 h post-administration. Although ALA was not detected in brain tissue, ALA metabolites including EPA, DPA, and DHA remained elevated up to 25 d post-administration . Studies have also shown a decline in FA enzyme activity in the liver of aged animals , potentially allowing the presence of ALA and LA in the blood, where it could be taken up in the brain. Additionally, Davis et al. found that mice fed a whole-walnut diet comprising 155 g of whole walnuts/kg diet, which is the equivalent of 80 g of walnuts/d in humans, to provide 20% of energy from fat, had changes in plasma markers, which were echoed in the liver metabolomics results. It was concluded that the walnut diet’s beneficial effects probably represent the effects of whole walnuts’ multiple constituents and not a specific FA or tocopherol .

Side Effects And Precautions When Eating Walnuts

Walnuts The Brain Food

Walnuts are tasty nuts or seeds that are very beneficial for your health. Walnut fruit contains protein, vitamins, minerals, and is high in healthy fatty acids.

The only side effect that doctors warn from consuming walnuts in reasonable amounts is an allergic reaction. If you suffer from tree nut allergies, you should make sure you are not allergic to walnuts before consuming them.

Walnuts And The Mediterranean Diet

You may have heard about the Mediterranean Diet, as it has gained popularity in recent years with no signs of stopping. Its popular for good reason, as its one of the best diets out there for promoting long-term health benefits.

The diet was discovered in the 1960s when research showed that men from the Mediterranean regions had lower rates of heart attacks. This sparked an investigation on whether or not their traditional Mediterranean diet played a part in their overall health.

The Mediterranean diet consists of eating meals with an abundance of vegetables and fruits, whole grains, oils, and fish, and less red and processed meats, and dairy.

Can you guess what food is a staple in this diet? Oh yes, its walnuts!

Walnoten: Goed Tegen Grijze Haren En Haaruitval

Niet alleen zijn walnoten goed voor je interne processen ook je buitenkant heeft er baat bij! Zo gaan deze noten grijze haren tegen, doordat ze veel koper bevatten. Dit mineraal speelt een belangrijke rol in de aanmaak van melanine, het pigment dat verantwoordelijk is voor de kleur van je haar. Een gebrek aan koper wordt vaak geassocieerd met vroeger grijs worden.

Maar walnoten doen nog meer voor je haar. Zo bevatten ze de voedingsstof biotine , die het haar versterkt, haaruitval tegengaat en haargroei bevordert. Het dagelijks eten van een handje walnoten doet daarom misschien wel meer voor je haar dan het kopen van peperdure haarproducten. Iets om over na te denken

Clearing Toxic Protein Aggregates

Protein aggregates are often toxic and can lead to the development of various neurodegenerative disorders such as Alzheimers, Parkinsons, and prion disease. Protein aggregation can be the result of mutations and/or disruption in various protein pathways. As cells in the brain lose their ability to clear misfolded proteins, they accumulate over time and lead to harmful imbalances within the brain. When insoluble toxic protein aggregation occurs, walnuts are thought to help reduce and/or stop it to a certain extent.

Walnuts Have Cancer Fighting Properties

Various trials have shown that consuming walnuts may help in preventing the development of certain cancers.

Scientists suggest that a combination of many of the beneficial antioxidants in walnuts helps kill off cancer cells. Lab trials on mice have found that tocopherols and other biochemicals can help slow the growth of colon, prostate, and renal cancer. Also, walnut compounds have shown to be effective in reducing the size of breast tumors.

Ellagitannins in walnuts turn into a compound called urolithin in your gut. Some studies have shown that urolithins can help to kill off prostate cancer cells and help prevent prostate cancer.

Unfortunately, there are very few clinical trials on using walnuts to treat cancers in humans. However, many doctors agree that a diet rich in antioxidants and omega-3 fatty acids has many health benefits, including helping to reduce the risk of cancer.

Antioxidants And The Brain

Antioxidants are key for preventing oxidative stress in the body.

Oxidative stress is caused by an imbalance of free radicals and antioxidant defence. An increased level of free radicals is toxic and can damage cells, thus affecting cell and membrane properties. Antioxidants neutralise these free radicals.

The brain is most vulnerable to oxidative stress as it consumes 20% of our bodys oxygen. For example, one type of dementia is caused by a lack of oxygen to the brain, leading dead nerve cells.

Therefore its paramount for our brain health to consume a diet which is high in antioxidant-rich foods, like walnuts.

Not only are walnuts rich in antioxidants, their antioxidant content is superior to most other foods. A study of antioxidant contents in 1,113 different food items ranked walnuts as second!

While this new research is intriguing, it also raises the question of whether walnuts are unique in some way. In fact, it may be the types of oils in walnuts that make them special when it comes to cardiovascular health. Walnuts contain a lot of polyunsaturated fatty acids, which are healthier than saturated fats. In addition, walnuts have alpha-linolenic and linoleic acids, which may have anti-inflammatory effects that keep blood vessels healthy, in addition to having favorable effects on blood lipids.

All nuts are not created equal. Many nuts are rich in monounsaturated fats, along with polyunsaturated fats. These are healthier types of fats than saturated and trans fats, but the specific combination of fats and polyunsaturated fatty acids contained in walnuts may be particularly good for cardiovascular health.
