Sand in Parle Glucose biscuits. Review on Parle G Biscuits

I am feeling really disheartening in writing this review as Parle G is one of my favorite biscuit since childhood. I have taken 3 packets of Parle glucose biscuit from a local store 2 days back in my area as I want to have it with milk because I was suffering from fever. I eat one piece of biscuit and find the taste really different. I thought this might be because of my fever then I ask my brother to have one piece and he also find the taste very different. Then after having 3 to 4 piece of biscuit we find out that the biscuit is mixed with high level of sand which is really injurious to health. Serious problem like kidney stone can be occur through this to normal people. Actually nowadays many companies are decreasing cost and not taking quality parameter into consideration. This matter is really critical for the people health especially children.
