## What is What did you eat??

■Profile
“What did you eat?” is the application to check your diet based on a Japanese food guide (Japanese Food Guide Spinning Top). This application was created by a female’s college students who studied nutrition and dietetics at the D.W.C.L.A.

■How to use this application
You choose the menu you ate from the menu list, and check the amount to eat in reference to the photographs. After registering the menu, you can check energy, nutrients, and food balance according to the Japanese food guide (Grain dishes, vegetable dishes, fish and meat dishes etc.).

You can compare your whole diet in a day with the Japanese food guide after registering your age and weight etc. This application is to support your health. The black cat of this application’s character named ‘Nyani-chan” supports your health quietly, too. Please enjoy it!

■Function

・You can list your whole diet in a day in one glance.
・You can list the previous month’s diet in one glance.

■Attention
This application was created as a part of the development of the tool for health promotion in Japan. We use the registered diet data after we agreed to use their data to develop the application.

※ The menu list of this application is based on dietary records from a 3-day weighing of 1,071 participants in the National Institute for Longevity Sciences-Longitudinal Study of Aging. The program that could check the food balances was developed using a menu list. It is confirmed in a study that energy and nutrient intakes are easily checked when using this program (T Imai etc. The Japanese Journal of Nutrition and Dietetics, 67（6）:301- 309、2009 in Japanese).

This application was created by female college students who studied nutrition and dietetics at the Doshisha Women’s College of Liberal Art (D.W.C.L.A) based on the program. We developed the application with photographs of the menu, and advice of black cat. This application developed an evidence based finding to return the results of research to society.

About the study use of data 
We want to study the dietary habits and nutrient intakes of the users from the data that user s registered after getting informed consent to use it. We want to study the characteristics and the health problem of the users.  We will announce the findings to all of the users to help their health improvements. Moreover, the data will be used to update the menu, and the application. The data may use individuals and groups for the purpose of the study. When we use the data, we will apply it to the study ethically, for example, after getting the approval of the Ethical Review Board of the research organization. 

When we study the data, we use the data after deleting the nicknames and addresses. We cannot use personal information such as gender, age, weight, and others outside of the study purpose. We cannot identify an individual because of the data process statistically before it has been analyzed and disclosed. We would have you understand the above-mentioned points, and, for the update of the application, please cooperate with the study use of registered data.

### 2/5 — 円グラフが正確に反映されていない

*2024-04-15, version 12.0.0*

血糖値が高いので使い初めて約1ヶ月。使い方にもだいぶ慣れ1日のカロリー計算が楽になりましたが、円グラフの脂質が異常に高く出ます。レタスと入れただけで脂質90%となりました。また運動メニューの「家事などの手伝い」は表現が適切でないと思います。家事を主とする主婦にとっては不適切な表現です。ぜひ修正の検討をお願いします。

### 2/5 — 登録に時間かかる

*2023-11-01, version 12.0.0*

アップデートしてから、食べた物を登録する
のに時間かかり過ぎで、登録するのに面倒
くさくなってしまいそうです。

### 1/5 — かたまります。

*2021-09-18, version 9.0.2*

早速使いたくて画像を撮ったところで待てど暮らせど進まず固まってしまいました。残念ですがアンインストールとなりました。

### 3/5 — 登録はしやすいですが…

*2021-04-22, version 9.0.2*

骨量が少ないと検査結果が出て、カルシウムの管理が出来るアプリが他には探せなかったので、こちらを使いはじめました。登録は簡単なので、続けられそうですが、他の方の意見にもある様に、メニューが少な過ぎて、似た物を探して登録するのに時間が掛かります。メニューが一般的な物しかないので、イタリアンなどの入力にはやや困りますね。改善を期待します！

### 2/5 — メニューが少なすぎて…。

*2020-07-20, version 8.0.0*

アプリ側で用意してあるメニューからしか記録できないので、そのメニューの種類が少ないのが困る。
素麺すらなかった…。

### 1/5 — 朝昼晩分けて入力できない。

*2020-07-03, version 8.0.0*

朝食、昼食、夕食が分けて入力できない。
1日のカロリー計算はできるが、毎食何を食べたかの食事の記録にはならない。
また、献立も驚くほど少なかった。

### 2/5 — ビタミンの記録はなくなったのでしょうか？

*2020-06-14, version 8.0.0*

ダウンロード時の写真のようにビタミンの項目がありません。

### 3/5 — 記入

*2020-03-28, version 8.0.0*

食べ物をg記入できて、食べた写真記録できたらうれしいです😃

### 4/5 — 使いやすいけど、、

*2020-02-08, version 8.0.0*

摂取した栄養などすごくわかりやすくて、毎日登録するのが楽しいです！
でも、「登録中」の画面がすごく長くて、ひとつ登録するのに何十秒も時間がかかるので待つのがしんどい。急いでる時はつらいです。

### 1/5 — 不正確すぎて使えない

*2019-08-20, version 7.2.0*

選べるメニュー少なすぎ。
レタス100%の脂質が8グラムだったりするので、めんどくささを堪えて一生懸命記録しても信憑性には欠けるかな…。
個人情報的にも不安だし他のアプリに乗り換えます。
