Hi Dr Li i have been listening to you for a number of years now and have learnt so much from you in regards to keeping my cancer away . I have had my kidney removed with a 40mm cancerous tumour . There is one thing that has confused me for a while now regarding the amino acid methionine . I am told it is an essential requirement for cancer to grow . So to lower it in my diet i try and go animal protien free but end up being so low in b vitamins i end up on intravenous supplementation even when i am daily supplementing on b12 .When i go back on animal protien my blood tests are fine and i feel great . I would love to here a video on your thoughts about methionine as i have heard you classify animal protiens like salmond as a big cancer fighter . Thank you again for sharing your wealth of knowledge cheers
