Do you like Japanese food? (This is correct-正しいです。)

This entry is going to deal with Japanese food.(This is correct-正しいです。)

Maybe it's a topic you've been waiting for.(This is correct-正しいです。)

I think that traditional Japanese food really represents the way of life that Japanese people once strictly adhered to in the past. For example, harmony with nature.

You might believe that sukiyaki and tempura are a typical Japanese cuisine.

In fact, with the introduction of recipes using meat and oil from abroad, meat and oil in the Japanese diet appear comparatively late in Japanese history.

The typical ingredients used for traditional Japanese foods are cereal, seafood, and vegetables, which include rice and soybean, fish and shellfish, and various vegetables respectively.

Traditional Japanese food tend to use less processed ingredients which preserves the natural flavors of the food.

In comparison with the traditional Japanese gardens, Japanese food is designed with natural aesthetic value. (However the natural flow of the dialog doesn't really provide for this comparison.)

Sushi, especially nigirizushi, is a culinary work of art that is renowned throughout the world. ( This is correct. 正です。)

It is a tiny elliptic rice ball seasoned with vinegar and topped with a thin-sliced ingredient, such as raw fish or sweet fried egg.

Fresh seafood as a topping on a sushi is usually spiced with wasabi. Wasabi is a very hot Japanese mustard.

You can reduce its pungency by drinking green tea served together with sushi. (This is correct) or You can reduce its intensity by drinking green tea served with sushi.

Vinegar, wasabi and green tea are proved to have bactericidal activity. Thus, they are a natural complement to sushi.

Sushi is know to be expensive, so Japanese people only eat it on special occasions.

However, miso soup is a popular soup that has been in the Japanese diet since the olden days.

The main ingredient of miso soup is soybean in its paste form. However, other ingredients include dashi, and vegetables.

All these ingredients are nutritious and rich with proteins, vitamins, and minerals.

Nowadays Japanese people eat highly westernized food. As a result, traditional Japanese food has a lower percentage of consumption, in Japan, than in the past.

Recently, traditional Japanese food has been re-evaluated as a tasteful and very healthy meal.

I too try to have miso soup for breakfast everyday. (correct)

If you are a woman who wants to keep in shape or a man who is worried about metabolic syndrome, then I recommend eating healthy traditional Japanese food.

This entry is going to be about Japanese food. [["deal with" is correct, but it can have a negative connotation. The phrase "deal with" typically implies that something is a problem that must be addressed.]]

I do think traditional Japanese food really represents the way of life that Japanese people used to take good care of - that is to say, harmony with nature. [[The word "do" might not be needed. "I think" is used to express an opinion. "I do think" is used to confirm or emphasize an unexpected or contradictory opinion. I think "take good care of" might not be the right phrase, but I am not sure what phrase is right. Maybe "strive for" or "aspire to".]]

You probably believe that sukiyaki and tempura are typical Japanese food. [[I think "probably" expresses a lot more certainty than かもしれません. I would consider saying "might" instead. I think you are using "belong to" to mean "part of a group", but in this sentence, it could also mean "owned by".]]

But in fact, they appear comparatively late in Japan's long history with the introduction of recipes using meat and cooking oil from abroad. [[It sounds unnatural for "long" to modify "Japanese history" because it might be trying to specify which "Japanese history" you are referring to. Since Japan has only 1 history, "long" should modify "history" instead of "Japanese history". You can say "Japan's long history" or "the long history of Japan"]]

If you are a woman who wants to keep in shape, or if you are a man who is worried about gaining weight, then I really recommend you try some healthy Japanese food. [[I have never heard it referred to as "metabolic syndrome" outside of Japan. I think "gaining weight" or "getting fat" are more common phrases in English.]]

Perhaps you have been told or heard that sukiyaki and tempura are typical Japanese dishes. (Alternative sentence)

Vinegar, wasabi, and green tea are proven to have bactericidal properties, so we must admit that sushi is quite rational food that combines these accompaniments with raw seafood.

Do you like Japanese food? (日本食はお好き？) ( fine or 'Are you fond of Japanese food ?' )

This entry is going to deal with Japanese food. ( fine, but it comes across a little abruptly. Perhaps it would be better to write : 'In this article I'm going to discuss ( or 'have a look at' ) Japanese food.' )

Maybe it's a topic you've been waiting for. ( fine, but again just a little abrupt. 'Food' is a 'chatty' kind of topic, so you should try to keep your tone a little lively. You could write : 'Perhaps it's just the (very) topic you've been waiting for!' )

I think traditional Japanese food really reflects a way of life, centred on harmony with nature, which Japanese people once used to practice (quite) faithfully.

Now, you'd be forgiven for believing that sukiyaki and tempura belong to are ( or 'count as' ) 'traditional' Japanese food. [ They certainly are 'typical', nowadays at any rate, but I think your point is that they are not 'traditional' in the sense subsequently indicated. ]

But in fact, they first appeared in Japan only comparatively recently with the introduction of recipes from abroad using ( or 'requiring' is probably better ) meat and cooking oil.

Typical ingredients used in traditional Japanese dishes include cereals, especially rice and soybeans, seafood, including fish, shellfish and seaweed, and, of course, a wide variety of vegetables which always feature prominently.

Traditional Japanese cooking ( or 'cuisine' ) tends to use less relatively few processed ingredients and thereby helping to preserve the natural flavour(s) of the food. [ Note (1) I think it is the 'cooking' rather than the 'food' that 'uses' the ingredients. (2) I presume you mean that 'fewer' ( ie a lesser number of ) processed ingredients are used, rather than that 'less-processed' ( ie not processed to the same extent as highly-processed ) ingredients are used. However, were you to write 'fewer' in your sentence, it would beg the question 'fewer than what exactly?', so you'd have to write something like 'fewer processed ingredients than are used in non-traditional-Japanese dishes' ( I'm exaggerating here to make the point of course). By writing 'relatively few', it is understood that a comparison with whatever is otherwise the norm is implied. (3) 'flavour' reads better than 'flavours', and there is no loss in meaning, because a variety of foods are being considered, so one expects a variety of flavours, and anyhow 'flavour' can refer both to the overall taste, as well as to individually discernible elements. ]

There are parallels here with the design of traditional Japanese gardens, which are also founded on principles of not only preserving and but also of giving prominence to natural qualities.[ This is quite an interesting comparison! I think the idea you're suggesting is that while the cooked dishes and the gardens are artifices required by people, nevertheless respect is shown for the creativity of nature and for her capacity to produce things which are beautiful both in themselves and as people perceive them. So the preservation of the 'gifts' of the natural world within the contrivances of the human world are both a recognition of and a mark of respect for the generosity of nature in enhancing the quality of human life. I've changed your sentence quite a lot - I hope you don't mind - but I think your point ( as I imagine it - and I may be totally wrong of course ) is really very interesting but just needs to be somewhat better integrated and more clearly developed.]

It is a tiny ( or 'small' ) ellliptic ( or 'oval' or 'oval-shaped') rice ball (which is) seasoned with vinegar and topped with a thinly-sliced ingredient, such as raw fish or sweet fried egg. [Note : (1) The use of 'which is' is fine grammatically. However in describing dishes and such like, it is usually omitted, mainly as it is an obstacle to the linguistic 'flourish' which is desired when describing zesty culinary creations. (2) Also 'elliptic' is a rather technical word, which seems out of place when describing food, particularly when you have previously described the dish in question as a work-of-art. (3) Where I come from any dish that is 'tiny' is not going to be appreciated as a work-of-anything. 'Small' might just be acceptable if the food in question is really delicious - which of course it is!]

Fresh seafood when used as a topping on a sushi is usually spiced with wasabi, which is a very hot ( or 'spicey' ) Japanese mustard.

You can reduce its pungency intensity by drinking (the) green tea which is (generally) served together with sushi.['Pungency' relates to smell, not to taste as such.]

Vinegar, wasabi and green tea have all been shown to have bactericidal activity an ( or 'a marked' or 'a significant' ) antibacterial effect, and so it certainly makes sense that these should be accompaniments for sushi, which, after all, contains raw seafood.

Sushi is a little expensive, (of course,) so we taste them usually get to eat it only on special occasions.

Miso soup, on the other hand, is very popular ( or 'commonplace' ) that and has been on everyday menu of a staple of the Japanese diet since (the) olden days ( or 'since olden times' ( no 'the' here) ).

Miso soup consists of miso paste, whose main component is soybean ( or 'which is mainly just soybean'), a soup stock called "dashi" , as well as various kinds of (more) solid ingredients ( or 'constituents' ) such as vegetables and ( or 'or' is probably better ) seafood.

All of these ingredients are very nutritious and are rich with in protein, vitamins, minerals, etc and other nutrients.[ Try to avoid finishing sentences with 'etc...', but rather try to find some general term that sums up your list. eg 'Attendances have been falling at baseball games, football matches, golf tournaments etc..' would be much better rendered as 'Attendances have been falling at baseball games, at football matches, at golf tournaments and at sporting events in general.']

Nowadays Japanese people eat highly westernized a lot of western-style food, and as a result ( or 'consequently'), traditional Japanese food has forms a (much) lower percentage ( or 'portion' is more apt in this case ) of their diet than it did in the past.[ I'm unsure as to whether you mean that the food is of the type eaten in the west ( ie western-style) or that it is Japanese food which has been subjected to western influence and additions ( ie westernized ). ]

But more recently, traditional Japanese food has become acknowlegded as being both tasteful (hmm - I think you mean 'tasty' as in 'delicious') as well as ( being) very (or 'particularly') healthy.

If you are either a woman who wants to keep in shape, or if you are a man who is (in any way) worried ( or 'concerned' - men never like to admit that they are 'worried') about metabolic syndrome your metabolism, then I'd ( ie 'I would' ) really recommend that you try eating some ( of our ) healthy Japanese food.

So, do you like Japanese food? [ More conversational, and the 'so' sort of jolts the reader and prepares them for the direct question.]

What do you like best in about Japanese food? ( or perhaps you mean 'What is your favourite Japanese food ? ' )

I think that traditional food truly represents the way of life that Japanese people once abided by—that is to say, harmony with nature. Note: 1) the first edit incorrectly split your sentence into two, of which the latter one is a sentence fragment. Rather than the "dash" mark, the correct punctuation to use is the longer "em dash" mark; 2) in the second edit, "once used to~" is redundant.

Traditional Japanese cooking tend to use less processed ingredients and preserve the natural flavouring of foodstuffs. Note: 1) nothing wrong with the use of "less," as ingredients are understood here to be a collective noun, and the context indicates a comparison being made with contemporary Japanese food; 2) Neither is wrong, but I like how the second edit changed the American spelling of "flavor" to the British spelling "flavour."

This could be compared with the style of traditional Japanese gardens, which are designed to accentuate natural scenic beauty.

Fresh seafood as a sushi topping is usually spiced with wasabi, a very hot Japanese mustard.

Vinegar, wasabi and green tea are proven to have bactericidal properties, so it makes sense that they are served together with sushi, which contains raw seafood. Note: succinct diction/syntax expresses the same idea in fewer words
