People need to get back to proper eating, I buy rice, pasta, fruit, veg etc and make meals out of them, fast food is a rare treat eaten maybe a couple of times a month (but then I think I'm seriously rebelling against the amount of crap BF shovs in his face I fully expect him to die before he hits 50 living off biscuits, crisps, pizza, fried chicken, chips etc he never eats rice, pasta or fruit and veg he's fucked up in the head).
Theres no such thing as bad food it's all in moderation, the problem is people are endlessly eating a stream of snacks that are high in fat and sugar without noticing instead of just having a sandwich.
For example in the first program I was surprised to hear that the baps used in the US for burgers contained corn syrup and that the chips contained sugar.
Then people are eating foods which are not filling for dinner but full of hidden extras, chicken in batter is never going to fill you up like chicken soup for example, people need to open their eyes and get back in the kitchen.
Ultimately it is up to the people to decide they want change, the food industry has jumped on every opportunity they can get to shovel more into our mouths but it is us the people who must be responsible for ourselves and excess self control, knowledge is power and the facts are out there for those willing to look.
