Sometimes gluten is even added to chips, which is really annoying.
When I was a model at 15, I was eating one red pepper a day, and if I had a big day of castings, I would survive off a bag of Haribo, which gave me the 500 calories a day that would keep me alive. I was congratulated daily on my appearance - the more vertebrae upon my back you could count, the better my auditions went.
I get particularly depressed by the way teenagers are portrayed in the media. They are massively underestimated. They are bright, intelligent people who are given less and less opportunity. They are an ignored generation.
One of the brilliant things I realised after I'd left school is that there are so many ways you can learn. I do this best on the job.
I am a Radio 1 DJ and campaigner for women feeling confident at every size.
Initially I struggled to find gluten-free products, but things have gradually improved, and now retailers like Holland & Barrett - with their new Free From range - are starting to cater for celiacs.
I became allergic to virtually all fruits and vegetables, and my weight tumbled. I am 5ft. 10in. but dropped to just 8 st. 7lbs.
For a while, I became a model scout and agent, thinking naively I could change the industry from the inside, and even kicked off the famous 'size zero debate' with an article I wrote to the 'Evening Standard' about my concerns from behind the curtain of the business, back in 2005.
Women's bodies have always been used as a spectacle and objectified.
I'm not saying all men are likely to cheat.
I had to learn to accept myself despite the fact that I was seriously underweight. I had to try and feel sexy.
Having an education is extremely valuable, but we need to help people connect their choice of studies to a potential career at an earlier age so that they are better prepared to get the job they want when the time comes.
Restaurants don't cater properly for celiac sufferers, and neither do supermarkets.
People don't tend to be unhappy in jobs doing something that they love, so I think it's important that those entering the world of work for the first time are given as much information as possible on how to get into the career that they want.
Hopefully, no one will feel self-conscious in anything that I've designed.
I've had versions of disability my whole life, first with my hearing and then when I couldn't walk for over a year.
I've always been passionate about the concept of helping the underdog. It just doesn't make sense to me as to what kind of person would take a huge platform and not use it to do something, to change something, to help people.
I think compassion is the only way to approach any subject, especially if it's to do with physical appearance. I don't think it's really about tearing something apart.
If someone had told me age 14 to start making serious decisions about my career, I'd have laughed!
Many weight issues stem from illness, be it physical or, indeed, emotional. And a large portion of people who sometimes struggle to maintain a 'healthy' weight deal daily with their own self-esteem crises.
