Not water but fruits and roots can mitigate hungover

Alcohol hungover is one of the most serious conditions at least subjectively. Therefore, there are several methods developed to prevent or mitigate the symptoms of hungover.

Many people believe dehydration is a cause of hungover. But a latest study denied this hypothesis.

Independent: Ultimate hangover cure can be made from ‘fruits, roots and leaves’, scientists claim

According to the researchers who wrote the article published in British Medical Journal, levels of water content in the body were not associated with the amount of alcohol consumption.

Instead, they prove that participants who took acerola, prickly pear, ginkgo biloba, willow and ginger root, as well as some minerals experienced mitigated symptoms of hungover such as headache. Thus, some fruit, roots, and leaves may be beneficial to counter hungover.

This conclusion is rational, or rather consistent with our daily experience. Therefore, I was not impressed to this result. Further studies are needed to develop a remedy for complete prevention of hungover.

Home cooking due to pandemic

It is often heard that the opportunity of home cooking has been increased since the novel corona virus pandemic made us stay home. Actually, I myself take almost every meal at home now, while approximately half of them were taken outside previously.

Home cooking can be healthier than dinner in a restaurant, some researchers say.

The Conversation: Home cooking means healthier eating – there’s an opportunity to change food habits for good

In my opinion, the main advantage of home cooking is the fact that you can take much vegetable at home. Most restaurants as well as fast-food franchises offer meals with too little vegetable. Also, the meal they provide contains much fat, red meat, and dairy products. They are suspected to harm our body in a longitudinal way.

It is useful to choose some products believed as good for your health in this opportunity. Nuts, red vegetables, some fruits, olive oil are likely to be beneficial.

On the other hand, cooking at home is a serious work for non-skilled people. Relying on preserved food too much for daily meal is no more healthy. Balanced diet is essential for us to maintain our health, especially in this crisis.

Mushroom is useful for many ways

Do you like mushrooms? I like very much.

Mushrooms is strange species. They are categorized as fungi. they parasites other plants to survive years. And they spread massive spores to reproduce them.

Some people dislike mushroom. It is perhaps because of its unique smell. But other than eating them, mushrooms are very useful in our daily life.

Inverse: 9 MUSHROOM USES: SURPRISING USES FOR THE FUNGUS THAT IMPROVE YOUR LIFE

I knew mushrooms are utilized as a fuel material. As well, it is commonly knew that some mushrooms are used for resource of Chinese medicine. But it is surprising that mushroom can be a building material as well as alternative leather.

By the way, I will tell you that Japan is a mushroom-rich county. In Japanese "mushroom" means so-called brown mushroom popular in Western countries. But there are many kind of names suggesting mushroom, such as shimeji, shiitake, hiratake, enoki, nameko, kikurage, and so on.

Among them, Matsutake is the most luxury mushroom in Japan because it cannot be produced in an artificial environment. It is deemed as a representative cuisine in Autumn. Japanese love matsutake's smell like French people love truffle's smell.

But, in terms of taste, shimeji is superior to matsutake, as many Japanese admit. Shimeji is very cheap, but a delicious item. In traditional saying, "Kaori matustake, aji shimeji [Matsutake smells best, but shimeji tastes best.]"

Ice wine and global warming

Do you have drunk ice wine? I have.

I had one in Germany several years ago. It was extremely delicious. Ice wine contained the sweetness of grape. Some people would not like it. But for me, as a sweet lover, it had heavenly taste, though I can drink only few amount of alcohol.

Ice wine is made from frozen grapes. Therefore, global warming is very hostile for ice wine makers. Indeed, the production of ice wine is decreasing in recent years.

On the other hand, in some regions farmers began to produce precious ice wine. The warmer the winter becomes, the more expensive the product is. Also they are engaging in keeping, further improving, the taste and flavor of the ice wine.

Global warming is an big issue. But it means the change of the environment. We have to adapt the changing game, besides of maintaining the current situation.

Low-carb diet prevent dementia?

The standard of nutrition frequently changes. Until recently, it was not recommended to eat multiple eggs in a day. But latest studies suggest that taking eggs would not contribute to increasing blood cholesterol.

As well, there is broad controversy regarding proper strategy for healthy diet. Some people recommend to reduce total amount of calories. Others emphasize the balance of carb and fat. Most researchers agree with the importance of exercise. But the magnitude of its effect is still under argument.

In recent, low-carb diet is popular for years. Many practitioners share the opinion that taking excessive carbohydrate, especially in a short time, is harmful. But why?

A recent study suggests the possibility that low-card diet reverses the aging of the brain, surprisingly.

The Guardian: Low-carb diet may reverse age-related brain deterioration, study finds

This article is written based on an academic paper published in PNAS. In this paper, the researchers claim brain deconstruction begins in late 40s. And changing diet to low-carb style will prevent the deterioration and even reverse the brain damage.

PNAS: Diet modulates brain network stability, a biomarker for brain aging, in young adults

The researchers hypothesize that brain degeneration while aging is accelerated by metabolic stress. They believe that the balance between glucose and ketone has a crucial role in brain damage.

However, they have not proven the concrete effect of low-carb diet on aging. As they mention, our dietary activity is so complex that it is difficult to make an experimental evidence.

At present, I believe the hypothesis that highly carb-dependent diet will harmful for your brain. But it is not sure how reducing carbohydrate is beneficial for cognitive function.

Manners in dinner

In recent years, I have more opportunities to take a dinner in a gorgeous restaurant, fortunately. I am fond of delicious meals. And I am curious to take specific cuisine in each region.

However, some first-class restaurants make regulations such as a dress-code. To be honest, I am often annoyed to obey such requirement.

Of course, rich meal matches rich clothes. It is not cool to enter a gorgeous restaurant with tiered clothes.

On the other hand, waiters often recommend me to take wines with each dish. Tasting wines with appropriate meal is splendid with no doubt. The issue is, however, I cannot drink alcohol.

Nowadays, some restaurants offer non-alcoholic drinks. I am very thankful to these treatment. In my sense, waiters in a European restaurant tend to feel surprised when I reject a wine. It is perhaps that few European people cannot drink. I myself, would like to concentrate the dish without alcohol.

Fiber prevents dementia?

A fiber-rich diet is believed to be beneficial for your health. It is mainly because of the fiber's effect on the improved movement of your intestine. Chronic constipation can be a cause of colon cancer. As well, fiber-rich diet makes you satisfied without taking an excessive amount of calory.


Recently, researchers focus on the anti-inflammatory effect of fiber. They hypothesize fiber-rich diet will prevent you from dementia.

Dementia, especially Alzheimer's disease, and some related illnesses are identified as a chronic degenerative disease of the brain. And, they can be connected with inflammation and oxidation. Thus, managing oxidative stress will reduce the risk for dementia.

Forbes: Eating A High-Fiber Diet Linked To Improved Brain Health In New Animal Study

Researchers found that a high-fiber diet reduced the level of inflammation in immune cells in the brain with experiments using mice. This result is suggestive because there are no reports so far to show the direct effect of fiber on the brain.

There are several differences between mice and humans in diet and metabolism, of course. Humans can eat a large variety of foods unlikely to any other species. Therefore, I am doubtful to adopt this outcome to humans directly. Nonetheless, it is well high-fiber diet can protect not only your body but also the brain.

Korea bans coffee from school

Korean government decided to ban any coffee from school.

The Guardian: Caffeine hit: South Korea bans coffee from every school

In South Korea, any stores and vending machines and in the primary schools and junior high schools will refrain from selling coffee and caffeine-rich products by this September.


In Korea, many students are indulged in taking massive caffeine, according to the media. One of the reasons is to prepare for the examination. Also, some children like to play online games at midnight. The government seems to worry about the health risk due to excessive caffeine.

Indeed, caffeine's dependency and adverse effect on the sleep-wake cycle is often discussed just recently. Compared to the conventional theories, more researchers claim the harm of caffeine. Also in Japan, the first case of fatality because of taking massive caffeine was reported the last year.

However, I am doubtful that the Korean policy will successfully protect the health of students. After the regulation, coffee providers will deliver products with caffeine to students with other than the direct selling in school. And more importantly, students can get coffee as much as they want out of the school. Therefore, banning coffee in school will not be effective, I am afraid.

On the other hand, the effect of enlightenment for students with providing information that caffeine is not safe at all will be expected a little. This idea sounds odd, perhaps. But Japanese tend to consider that regulation makes people regulated through its spirit, not the rule itself. Korean resembles Japanese to some extent in their pattern of thought, I think.

Chicken Noodle is 60 y.o.

This year is 60th anniversary of Nissin Chicken Ramen.

The Japan News: World’s 1st instant noodles to commemorate the 60th anniversary

Nissin Food Products Co. was founded by Momofuku Ando. Its most significant product is the instant noodle. Nissin developed a way to deeply fry the noodle to preserve it for a long time. Nowadays, the instant noodle is sold in many countries especially in Asia.


To be honest, Chicken Ramen is for children, I think. It tastes a little too oily. Instead, Nissin provides a large number of noodles. You must find a favorite flavor.

How to build your muscle

Many men, as well as some ladies, want to gain a body with rich muscle. They are eager to shape the optimal body by resisting the temptation of sweets and a lazy lifestyle.


Nowadays, the proper way to grow your muscle has been established to some extent, though there is no silver bullet. Exercise and diet are essential, as you know. Muscle grows after it was damaged. It is the reason why you need heavy resistance exercise to gain musculus body. Longitudinal but non-resistant movement such as walking is not beneficial to grow muscle, while it can make your fat burned.

Also, a protein-rich diet is helpful to convert your intake into the muscle. In Japan, "Salad-chicken," usually smoked chicken fillet, is popular in recent years. It contains a large amount of protein with low fat. I sometimes eat it. It tastes good, but continuous taking is boring.

Independent: THIS IS HOW MUCH MUSCLE YOU CAN GAIN IN A MONTH, ACCORDING TO EXPERTS

A benefit of gaining muscle is improving your metabolism. Musculus body consumes high energy. Thus, you are unlikely to gain excessive fat. Also, muscles prevent you from aging. Elder people with poor muscles are likely to cause fractures.

You need not be powerful physically thanks to the modern technology. Nonetheless, muscle is important for your better life.

Dog eating day in 2018

The annual Yulin dog meat celebration was performed this year.


In some Eastern nations, dogs have been bred for meat. But, this habit is criticized by mainly Western people. Recently, South Korea officially illegalized the slaughtering dogs for meat.

Vanguard: China dog meat fest opens as S. Korea goes the other way

As I wrote in the past, I will never eat dogs. But, to be honest, I believe slaughtering dogs for meat is not a cruel act. Muslims are prohibited to eat porks because they pigs are spiritually dirty. Hindu never eat beef because cows are sacred according to their doctrine. Every religion and culture have their own ideology, any of which should be respected. There are clusters of people who like to eat dogs.

My past entry: Discussion about eating dog meat in China

Some people might think that dogs should not be eaten because they are prettier, or cleverer than cows and pigs. But, I think this idea is improper. Any species have their own lives and spirits. We, humans, deliberately distinguish the value of their lives for convenient reasons. We breed cows for the deliciousness of beef. We plant corns because they are easy to be harvested. We should be aware of the arrogance of ours on the selection of life.

Artificial sweetener may not raise your blood sugar

Nowadays, there are several types of artificial sweetener. They do not include calories or are hard to be absorbed in the human intestines. Therefore, they seemed not to be harmful despite they taste sweet.


However, artificial sweeteners are often criticized recently. Some researchers claim they can raise blood sugar level in spite of they lack energy. Also, insulin is secreted when the brain feels sweet even if there is no sugar to be absorbed from the blood into the tissue, according to another researcher.

Are sweeteners risky for us as well as white sugar? Fortunately, or unfortunately, there is no evidence to support it.

A recent meta-analysis study revealed that combination of recent studies suggested the stability of blood sugar level in taking artificial sweeteners.

Nature: Glycemic impact of non-nutritive sweeteners: a systematic review and meta-analysis of randomized controlled trials

The collected articles in this study were randomized-controlled trials (RCT). Therefore, the result of meta-analysis is relatively trustworthy. As far as I read the article, there are no critical flaws in this article.

It does not mean, however, sweeteners are not harmful at all. There are several possibilities of harm caused by artificial substances. We need not be afraid of them too much. But I recommend you not to depend on artificial sweeteners in your diet.

Eel price rises

Eel is an important food for Japanese. Many Japanese are fond of eat Una-ju, or Una-don (grilled eel on the rice) in summer. Eel is believed to protect your body from diseases during summer. Indeed, eel contains rich protein and fat.


However, the price of eel is continuously increasing in recent years. I guess the cost has been more than doubled in a decade.

One of the reasons is a shortage of catching juvenile eel school. Most eel is framed in a pond. But artificial hatching of an eel is not feasible so far. Therefore, young eels caught in the sea are necessary for harvesting ell.

The Japan News: Eel prices expected to surge again this year

The reduced amount of catching eel has been focused for a couple of decades. Then, the hike is not surprising. The other days, the eel was a luxury food in Japan.

I hear that total farming is under experiment in several facilities. The government expects hatching eel will be industrialized within a few years.

In the modern era, we have few opportunities of eating natural food. It is sorry, but not a disgrace, I think. It is of the importance that nobody will starve.

The egg is healthy, the final answer

One of the victims mostly disgraced in the last century may be the egg. We had been told not to eat too many eggs for protecting our health. It was for an egg contains rich cholesterol.


However, recent studies suggest the safety of eating many eggs. A couple of years ago, authorities amended the statement about the risk of eggs. It was the most surprising change in the modern nutrition.

And also, there is an interventional study about the effect of eggs. In this study, participants with diabetes or the risk of it were encouraged to eat many eggs or fewer eggs according to the group assigned. As a result, members of both groups accomplished the reduced body weight with maintaining the metabolic status. No significance was observed between groups.

Hindustan Times: Eggs are good for you. Yes, even the yolk, says this study

This result itself is not surprising. But, it is splendid that an interventional study for a year was conducted to prove a hypothesis.

Strawberry picking

Today, I went to Toke for strawberry picking.


Strawberry is one of the most popular fruits in Japan. Most Japanese like strawberry because of its sweetness. Strawberry is used in cakes and other desserts. But eating raw strawberry is the best way to enjoy its taste.

In early spring, some farms conduct strawberry picking tour. Customers can pick and eat strawberries as many as you wish for a particular cost.

Today, I visited Nakamura farm in Toke located in Chiba prefecture. I ate approximately 50 strawberries in the 30 minutes.

There are several brands of strawberry in Japan. Tochiotome, Benihoppe, Yotsuboshi, Ohkimi, and some other type of strawberries are available on this farm. Each type varies in their taste. I enjoy them.

Is fruit sugar not harmful than sugar?

The nutrition is an immature science. Every year, a new hypothesis emerges. For example, eating multiple eggs in a day was deemed to be harmful, the other day. But, recent studies suggested an opposite result. Following the evidence, the WHO permitted eating eggs.


The sugar has been a villain, however, for several decades. Excessive sugar taking is highly likely to be harmful to your health.

On the other hand, fruits are said to be healthy. But, fruits contain several types of sugar. How do you consider this paradox?

A possible answer is written in the article below.

The Conversation: If sugar is so bad for us, why is the sugar in fruit OK?

Thus, fruits contain rich fiber. Therefore, you cannot take an excessive amount of sugar from fruits.

It is noteworthy that the sugar in the fruit is not different from free sugar. Thus, if you take an extreme amount of fruits, it would be harmful. There are no ultimate foods.

Coffee flavor

I like drinking coffee. But I have no idea how can I make coffee taste good.

A couple of years ago, I bought a coffee maker. It can create coffee as well as some specialty beverages such as Tea Au Lait.


I am satisfied to drink coffee using this machine. It costs only 50 cents per cup.

Nestle Dolce Gusto (in Japanese)

But, some people are enthusiastic to create better coffee. The quality of coffee flavor is influenced by several elements. Furthermore, there are many variations of specialty coffee.

ABC News: What makes a specialty coffee taste good? The science behind your morning cuppa

In Japan, canned coffee is also popular. You can buy it using a vending machine. The taste is inferior to coffee made by a barista, according to coffee lovers. But, I cannot detect the difference between them.

Grape cures your depression? not sure

Depression is one of the diseases which do damage to your life a lot regardless of your age, gender, or occupation. In recent years, WHO has identified depression as the second worst disease in the world for health cost. It is rational considering that depressed people feel difficult to work efficiently. Of course, the most tragic outcome of depression is suicide. But even if you have no suicidal thought, your productivity would be considerably lowered by depression.

Also in this blog, I have mentioned many things which are potentially useful to overcome depression. Nowadays, medication, psychotherapy, and some other physical treatments have been proven to mitigate depressive symptoms. But there is still no final solution found.

Apart from special care given by doctors and psychiatrists, there are some ways expected to deal with depression effectively. Most of them are still under discussion. But, regular exercise and exposing daylight are certainly effective to cure depression, despite their power is limited.

On the other hand, there are no particular diets to be proven as effective. Eating fish including rich omega-3 fatty acid can potentially protect you from depression. But once in the depressive state, fish has little effect.

If the daily foods had strong effects on your health, they would be rather risky in other aspects. Thus, the effect of each particular food to promote your health status must be minimal.

Nonetheless, many people expect foods to help them. Researchers are seeking various possibilities. Among them, the polyphenol in grapes is focused recently.

Hindustan Times: Feeling depressed? A handful of grapes can help make you feel better

I do not believe the effect of grapes to cure depression, to be honest. Experiments using mice propose limited evidence, especially in the theme of the human mind. Of course, you can eat grapes expecting it will relieve you of the depressive mood. It may be bee beneficial more or less. In contrast, if you dislike grapes, you should not try them. Doing the things you do not like is generally no good in the depressive state.


On the other hand, the relationship between depression and inflammation described in this article above is interesting. Most psychiatrists do not believe the hypothesis that depression is a result of inflammation in brain cells. But, there were some patients I met who became seriously depressed soon after catching a common cold. Oxidative stress is also under discussion as a cause of many psychiatric illnesses. More research is needed to clarify the real figure of depression.

You should choose sushi restaurant because salmon have tapeworms

In California, a man came to a general physician to complain an abnormal phenomenon with showing its astonishing cause. He was suffering from bloody diarrhea.


And he said to have found a 5-feet tall tapeworm emerged from his anus.

International Business Times: Sushi lover finds 5ft tapeworm dangling from his rectum and yanks it out himself

The doctor brought him to an emergency room immediately. He was treated with medication to eliminate parasites in his intestine. Fortunately, he seems to have got recovered.

Tapeworm is a kind of parasites which is sometimes detected with a regular examination, or accidentally, even in citizens living in an urban area. Typically, tapeworms cause no harm to the human body. But in rare cases, they can be fatal.

The man introduced in this article above was fond of eating sushi. He ate raw salmon every day.

Actually, salmons have parasites frequently. We Japanese like salmon sashimi. Ordinary Japanese sushi restaurants in Japan serve only properly examined or processed fish. Fishmongers suggest some raw pieces which should be heated before eating.

The association between hot tea and glaucoma

Glaucoma is an eye condition potentially damaging the eyesight. People with glaucoma lose the field of vision gradually to result in the blindness finally. The cause of glaucoma is still unclear.

A recent study suggests that hot tea drinking might prevent you from glaucoma. According to this article below, regular consumption of hot tea was associated with lowered risk of glaucoma by 74%.

The Guardian: Could drinking tea really be linked to a lower risk of glaucoma?

As some researchers mentioned in the article above, however, this result is quite doubtful. I am afraid this hypothesis is not trustworthy regardless of the content of the original research report.


First of all, the definition of hot tea is vague. Different from coffee, many types of beverage are called "tea," such as green tea, jasmine tea, and even avocado seed tea. Each ingredient of tea is far different from each other. Some tea shares caffeine. But this study has failed to detect the association between caffeine consumption and the prevalence of glaucoma.

Second, the false positive association is possible. There are many other variables among participants potentially influencing the onset of glaucoma than tea consumption. It is possible that the researchers erroneously detected the association. I believe the authors made a statistical analysis of proper method. Nonetheless, type 1 error cannot avoid entirely.

In recent years, the effect of caffeine on the human health is in the process of clarification. But there is still no fixed conclusion. The outcome of consuming a massive amount of tea is in the mist. I recommend you taking balanced diet regularly.
