Drinking Cold water after a meal = Cancer! Can you believe this?? For those who like to drink cold water and that's large amount of Americans, this article is applicable to you. It is nice to have a cup of cold drink after a meal. However, the cold water will solidify the oily stuff that you just consumed. It will slow down digestion. Once this sludge reacts with the acid, it will break down and be absorbed by the intestines faster than the solid food. It will line the intestine. Very soon, this will turn into fats and lead to cancer. It is best to drink hot soup or warm water after a meal. If none of the previous choices are available then it would suffice to use room temperature liquids.
