I heard non-organic milk has lots of pesticide etc. I drink non-organic, is it really that risky?

The jury is still out on that one. There may be pesticides in non-organic milk but I'm not sure how high the levels are. What really concerns me about non-organic milk is the hormones that they give cows on big dairy farms. They also regularly give them antibiotics which may be creating antibiotic resistant bacteria. For that reason, I only by organic milk. I have two small daughters and I just don't want to take the chance.

No, such contents r controlled by law.

Eat only when hungry and not more than thrice a day. Nothing other than water in between. Include plenty of uncooked vegetables and fruits in each meal, preferably 50%. Chew each morsel at least 32 times to activate ur body to generate signals of hunger/fullness. Obey these signals.

Take light exercises and brisk walks regularly preferably twice a day.

U will achieve what u have not even dreamt and that too in a reasonable time. Do not be in a hurry.

Well, besides pesticides, the milk also has bacteria, blood and puss in it. The blood and puss are from the sores on the cow's udders that are created b/c the machines milk them too much and too hard.
For me, all animal by-products are risky and I actually no longer drink cow's milk because of that. Don't believe everything you hear...really do your research. Just b/c milk is labeled "organic" that might mean that the cows were never fed antibiotics or steroids....that doesn't mean that there's not blood and puss in that stuff too.
Good luck! :-D
