We all know that dairy products contain calcium for our bone (growth), muscle contraction, etc....
Another source of calcium that is Sardine .. because the processed sardine in the tin contained bone that can become our source of calcium.
It was a surprise for me when the books/articles recommend Tofu as a source of calcium...
This really intrigued me for a long time ...because I couldn't understand the logic behind it - how can the soya product become a main source of calcium?.... until a few days ago, when I read the book - "You're What You Eat..." by Chia Joo Suan ...
She explained that in the process of making tofu, or the "cheese of Asia", the shi gao (that is gypsum/CALCIUM SULPHATE) was added to coagulate the soya drink....
So, the source of Calcium from tofu comes from the addition of calcium sulphate....
mystery solved ...
