Walnuts are vascular scavengers? Walnuts Make Blood Vessels Healthier, Study Finds

Zhang, 55, was diagnosed with high blood pressure last year. Since then, he has been following the doctor's advice and taking medicine on time every day. His blood pressure has been under stable control.

One day, he and some old friends out for tea.

"I have to go to the market to buy a bag of walnuts before I go home. I heard that they are good for cardiovascular health. I will buy them to try." Everyone was chatting when Lao Liu suddenly made a remark.

"Walnuts have cardiovascular benefits? Really? That's the first time I've heard that." Lao Zhang was dubious.

"You CASUALLY SEARCH THE NET SEARCH, THE EXPERT ALL SAY SO OF, WALNUT STILL BE CALLED 'BLOOD VESSEL SCAVENGER'!" Lao Liu said with certainty, so they went to buy walnuts after the show.

After Zhang bought a bag and went home, he would eat two or three every day, but once he didn't pay attention and ate a moldy walnut!

After gargling, Zhang did an Internet search and was shocked to see someone saying, "Eating a moldy walnut will detoxify your liver for 40 days." Eat so long walnut also did not see the body has what good change, the result accidentally ate a moldy actually still hurt liver!

One, eat a moldy walnut, liver need detoxification 40 days?

It IS NOT JUST WALNUT ACTUALLY, THE NUT SUCH AS COMMON PEANUT, ALMOND, CASheW IS KIND OF FOOD TO APPEAR EASILY MILDEW SITUATION, THAT ATE CARELESSLY, SHOULD LIVER deTOXIFY REALLY more THAN A MONTH?

Eating moldy walnuts may indeed do harm to your body. Because when walnut mold, will be affected by Aspergillus flavus, parasitic aspergillus and other Aspergillus fungi contamination. The secondary toxic metabolites of these fungi, aflatoxins, are recognized as one of the most carcinogenic and teratogenic harmful substances.

Half lethal dose (LD50) is commonly used in medicine to describe the toxicity of a toxic substance, which means that half of the animals will die if they eat this dose.

The LD50 of aflatoxin is 0.249 mg per kg of body weight, and an adult weighing 60 kg, for example, has a risk of death as long as the intake of aflatoxin reaches 15 mg.

Because aflatoxins are mainly metabolized in the liver, they are highly hepatotoxic. If you eat moldy walnuts or other nuts, it can cause acute and chronic liver disease and increase the risk of liver cancer.

If you eat a moldy walnut, how long does it take your liver to metabolize all the aflatoxin in it? The answer is different.

The amount of aflatoxin in walnuts may vary depending on how moldy they are, and the ability of the liver to metabolize it varies from person to person.

Therefore, usually must not eat moldy walnuts, peanuts and other nuts, if eat into the mouth nuts bitter, should be spit out as soon as possible and rinse with water. However, nuts such as walnuts contain a variety of nutrients and are good for human health when consumed in moderation.

Two, walnuts can not only prolong life, but also make blood vessels healthier

Many people believe that eating walnuts is good for your brain, but the benefits of walnuts may be more than you think.

Walnut has high nutritional value and is known as one of the world's "big four" dried fruits. Walnuts contain 14.9 grams of protein and 58.8 grams of fat per 100 grams, with polyunsaturated fatty acids accounting for 76.2%.

In addition, walnuts also contain a variety of nutrients needed by the human body, including dietary fiber, vitamin E, carotene, and calcium, iron and so on.

If you insist on eating a moderate amount of walnuts every day, you may reap the following benefits:

1. Reduce the risk of cardiovascular disease

In January 2020, a study published in the Journal of Nutrition suggested that regular consumption of walnuts may help reduce the risk of cardiovascular disease.

Simply put, the unsaturated fat in walnuts helps reduce bad cholesterol in the body, which in turn reduces the risk of cardiovascular disease.

2. Improve intestinal health

In addition to finding that walnuts protect against cardiovascular disease, the study also found that walnuts promote gut health.

The researchers noted that the unsaturated fatty acids, omega-3 and fiber in walnuts contribute to a favorable gut microbiome, which not only improves the gut environment, but also helps lower blood pressure, which in turn reduces the risk of heart disease.

3. Help prolong life expectancy

A study published in the journal Nutrients found that people who ate 140 grams or more of walnuts per week had an increase in life expectancy of 1.3 years, a 14 percent reduction in all-cause mortality and a 25 percent reduction in cardiovascular mortality compared to people who never ate walnuts.

Even eating a few handfuls of walnuts a week may help prolong life, especially for people who already have a poor diet, the researchers note.

4, reduce the risk of diabetes

In June 2018, an epidemiological study published in the journal Diabetes/Metabolic Research & Reviews found that those who reported eating walnuts had a lower risk of developing type 2 diabetes compared with those who did not consume any nuts.

Three, how to maximize the nutrition of walnuts?

Walnuts have so many benefits, so how do we eat walnuts in order to get the most out of them? Here is to teach you the healthy way to eat walnuts.

1, do not tear the walnut skin

Walnut skin is the key to high antioxidant properties of walnuts, which are astringent to eat because they contain polyphenols with strong antioxidant capacity. In general, the more astringent it is, the stronger the antioxidant.

2, choose the original taste, open and eat

When eating walnuts, it is recommended to choose the original flavor, without adding salt or sugar.

Other than that, walnuts are best served fresh. Because when the walnut is opened, the broken walnut meat has more chances to contact with oxygen, which is easy to oxidize and deteriorate, which contains vitamin E and omega-3 fatty acids will be destroyed, and polyphenols and other antioxidant substances will be lost.

3, 2-3 a day is enough

Although walnuts are high in nutritional value, they are also high in calories. It is recommended that walnuts be used as a snack to provide certain nutrition and energy supplement in addition to three meals a day.

According to the dietary guidelines for Chinese residents, the recommended intake of nuts is 50-70g/week, averaging about 7-10g/day, which is equivalent to eating 2-3 g walnuts with skin every day.

4. Some people suggest eating less

Walnuts are good, but not for everyone.

Obese people: walnut fat content and energy are higher, should not be eaten;

Patients with liver disease: the fat intake is emulsified by bile secreted by the liver in the duodenum, and then digested and absorbed. Patients with liver disease are prone to aggravate the disease if they eat too much.

Patients with gallstones: walnut should not be eaten, otherwise it will stimulate the gallbladder, causing severe contraction of the gallbladder;

Walnuts are rich in unsaturated fatty acids and antioxidants, which have been linked to cardiovascular health, gut health and longer life. But the fat content of walnut is higher, eat too much easy to cause fat, so eat 2-3 every day can.

When choosing walnuts, try to choose the appearance of complete, smell no fuel consumption flavor, but also pay attention to the warranty period and other information. It is recommended to put the walnut in the refrigerator after opening, so as not to spoil.
