I think you're rather missing my point. We aren't talking about healthy people, we're talking about sick people.
The whole point of this thread is whether or not supplementing your diet, which absolutely should be healthy and balanced first, can be beneficial to the unhealthy individual if other steps have failed to make a difference.
My statement regarding prescription of food, and supplements, was in argument against your statement that GPS don't prescribe it. My point was that they must prioritise proven medicines over supplementation because their time is finite, and medication has far more (big pharma funded) research behind it leaving the NHS with no choice. There is an epidemic of poor eating in this country and I genuinely can't get my head around the fact that you seem to think the NHS is doing even close to enough to prevent it.
The modern western diet lacks the nutrients it did even 50 years ago due to over farmed land, and quickly grown mass produced animal products, fed grain rather than grass and farmed rather than found free. When this is compounded by chronic inflammatory illness, there is evidence that exists that supplementation may work for some people. Which is what I've said many times. Evidence has already been linked to support this is the cas for turmeric.
As I have stated before, I have severe, systemic auto-immune disease that the NHS has struggled to manage for years, with surgery offered as the last resort to one of these conditions, and shrugged shoulders and crossed fingers for the others.
I was a personal trainer for years before I became ill, my diet was excellent and I lived a clean, active lifestyle; it wasn't enough.
Since becoming ill I have cycled so many oral and IV steroids that I can barely tolerate most of them, with beclametasone being one of the few whose side effects I can still bear. I've been trapped in this cycle for years, with the steroids weakening my bones to the point of Osteopenia, and no medical respite offered bar removing my entire colon and hoping my other inflammation can be managed without steroids (I am on immunomodulators and anti-intergrins also, anti-tnf didn't work).
By slowly trialling and integrating many supplements into my diet, proported for their anti-inflammatory and immuno modulating effects, coupled with specific dietary choices, specifically the consumption of turmeric, I have reached a point where my dose of steroids is almost negligible. I am close to complete IBD remission, my liver markers and cRP have diminished significantly and I haven't had an attack of pancreatitis in months.
I have never said supplementation is necessary, or works for everyone, or that it is easy, or that one pill will fix everything. But I can tell you with absolute certainty that for some people with chronic illness, the right combination of supplements can be utterly life changing, and even achieve what aggressive, damaging drugs cannot.
