“I met Jan Martijn about 1.5 years ago and I told him that I have ankylosing spondylitis and that I use Enbrel for it. Because of this medication, I had a chronic cold all winter long, with pneumonia almost every year as an outlier. Jan Martijn told me what a different diet could do for me. He also told me that there was a study going on where they were investigating this (healthy food versus medication). I was very inspired by this and started to investigate what this could mean for me. I started drinking less alcohol and eating less meat and fish and more vegetables. Jan Martijn also told me that I shouldn't be too strict with myself. Even if I were to eat 80% healthier, I would already be a long way there. This helped me enormously. In the end, after 1.5 years, I am eating vegan and I no longer need my medication. I feel better than ever and have also lost 8 kilos. I am very grateful to Jan Martijn for this eye opener”.
