Firstly Ben it helps if you use the quote button so we can all see which bits are your comments and which are other peoples without having to check.
I agree not all studies that prove a link are false, there are many which are correct. It is of course correct that 1 chocolate bar does not cause acne. Therefore they can technically say that chocolate doesn't cause acne. The problem is an excessive amount of toxins from junk/processed foods over time can cause issues. Doesn't matter how young or old you are, it is based on genetics, some have stronger mechanisms for dealing with toxins and/or excess hormones than others. That is why some get acne and others do not. There are of course other causes of acne but the majority are linked to an overloaded liver including certain allergies.
The concept is simple science, the big picture is complicated but it all boils down to a simple principle. Anyone with even an ounce of common sense would understand what you eat has a dramatic effect on the way your body functions including the health of your skin.
I read one of your posts where you say about drinking more water as been a good thing for acne. So if drinking water which runs through some of the same system as food has an effect on acne in your mind why can't food?
I do of course completely agree with your comments about Doctors, no one can ever always be right.
I am not sure if you actually read what you had written above. I believe you to be relatively intelligent from the posts I have read but that is pretty much the most stupid thing you have said. You would find few people who would ever say preservatives were worse than eating bad food. Preservatives are very valid in modern society. I honestly prefer a world which has preservatives, without them it would make food choices, storage and preparation so much more difficult but I also understand the negative effects they can have with my health. One of the biggest used preservatives (Hydrogenated Oil) is quite bad for us but the food companies continue to use it because it is very cheap to produce and gives a lot of the products we eat a long shelf life.
Your comments about heart disease may be true, I am not really interested in checking. Most likely the new medication and testing methods we have for certain medical conditions is giving these so called percentage those extra 10 years. One thing I will say is it is obvious people are suffering health problems due to bad diet. I don't need to spend time searching on google or reading books, all I have to do is walk down the street and see how many people are clinically obese.
