飲食誤區吃蔬菜的九大健康誤區(2)

 誤區七:隔頓隔夜吃


  比較節省的人可能一頓吃不完的菜就會放置到下一頓吃,這時候菜的營養幾乎就已經沒有了。經測定,炒好的青菜放15分鐘,維生素C減少20%,放30分鐘損失30%,放一小時降低50%。而且隔頓隔天的菜還易變質,吃了易發生食物中毒。所以好現燒現吃,既衛生又有營養。藥神網壯陽藥韓國奇力片雙效犀利士英國威馬泰國馬力丸美國黑金犀利士clalis



 誤區八:加油太多

  不少人認為,炒菜放油少了就不好吃了,所以就放很多油。但是植物油和動物油一樣,每克油都產生9千卡熱量,攝入太多都可誘發肥胖或因熱量攝入過多而致高血脂、心腦血管疾病,所以炒菜加油要適當,每人每天吃油25克,不超過30克為宜。

  誤區九:菜湯必須倒掉

  燒菜時大約有30%-70%維生素C及部分水溶性營養素會溶於湯裡。如果炒菜之前已經用水焯過一次,去掉了草酸、亞硝酸鹽和農藥,並且炒的時候油和鹽放得也比較少,那麼菜湯喝掉是無害的。

  有人為節省時間,喜歡提前把菜炒好,然後在鍋裡溫著等人齊了一起吃或下頓熱著吃。其實,蔬菜中的維生素B1在炒好後溫熱的過程中會損失25%。炒好的白菜若保溫30分鐘會損失10%,若長到1小時,就會損失20%。吃菜,這聽起來是再尋常不過的事情了,但是如果吃得不科學,也會對健康產生不利影響。那麼,蔬菜怎麼吃才是科學、健康的呢?

  1、多吃新鮮蔬菜

  新鮮的青菜,買來存在家裡不吃,便會慢慢損失一些維生素,如菠菜在20℃時,存放24小時維生素C損失則達84%。因此要盡量多吃新鮮蔬菜。

  2、不應捨棄的營養部分

  例如豆芽菜,有人在吃時只吃上面的芽兒而將豆子丟掉。事實上,豆中含維生素C比芽兒的部分多2-3倍。再就是做餃子時把菜汁擠掉,維生素會損失70%以上。正確的方法是,切好菜後用油拌好,再加鹽和調料,這樣油包菜就不會出湯了。

  3、炒菜用旺火

  據測定,大火快炒的菜,維生素C損失僅17%,若炒後再燜,菜裡的維生素C損失則為59%。因此炒菜要用旺火,這樣炒出來的菜,不僅色美味好,而且營養損失少。炒菜時加少許醋,也有利於維生素的保存。德國必邦威而鋼印度必利勁一炮到天亮Goodman增大丸GHBFM2安眠藥迷姦藥





  4、炒好的菜趁熱吃

  有人為節省時間,喜歡提前把菜炒好,然後在鍋裡溫著等人齊了一起吃或下頓熱著吃。其實,蔬菜中的維生素B1在炒好後溫熱的過程中會損失25%。炒好的白菜若保溫30分鐘會損失10%,若長到1小時,就會損失20%。
