- The pH level in the mouth declines considerably five minutes after the consumption of any of these sugars >> IELTS TUTOR hướng dẫn CÁCH DÙNG "CONSUMPTION" TIẾNG ANH
- Body 1: Viết về acid level 5.5
- When the pH level in the mouth is kept above 5.5, acidity is such that teeth are unlikely to be in danger of decay >> IELTS TUTOR gợi ý Phân biệt "unlike, unlikely, alike, likely & like" tiếng anh
- Sweet foods cause pH in the mouth to drop for a time, and the longer pH levels remain below 5.5, the greater the opportunity for decay to occur >> IELTS TUTOR hướng dẫn Cách dùng động từ "Occur" tiếng anh
- Body 2: So sánh fruit sugar, cane sugar & honey
- Cane sugar:
- Approximately five minutes after consuming cane sugar, pH levels drop to as little as pH 3.5.
- They then begin to rise slowly but do not rise above pH 5.5 until at least 30 minutes have elapsed.
- Fruit sugar:
- Fruit sugar, which causes the mouth's acidity to fall to just above pH 4, poses a danger for a shorter period (tooth decay is unlikely 20 minutes after consumption)
- Honey:
- Cane sugar:
