The comparison in two groups with about 25 patients each is just that an intervention will help in the rather short time span of 20 weeks - as opposed to no intervention.
This stuff demonstrates that it is worth looking into it, especially which of these interventions are actually working well. It is very likely that vegan diet is contributing much, it is likely that a healthy balanced diet would be sufficient while being much more simple to adhere to.
@EllieK
This is a simpliciativ world view. First.of all, I am actually vegan.
Second, anecdotal evidence is no evidence. That is where studies help, Thai study does not say mich as explained before.
If you prefer conspiracy, go for it. But neither food industry nor "Pharma" would be much phased by this study, even if there was more evidence to it.
And if that is your level,.are you sure.it is not rigged by the B12 supplement Industry? This is bonkers.
@EllieK
The study for sure is neither needed to tell everyone to eat healthy and to change.to a mainly plant based diet, that is already known to be better.
That random supplements are a scam is also proven over and over again. No worth there.
This study just proves that a multi level intervention can benefit Alzheimer's patients - short term. If it how much the vegan diet contributed is not even checked.
@CStamp
This diet includes fish and poultry, that is why there is no B12 needed.
But also I can't find a study that would support your claim, can you point out any good quality evidence? All studies I looked at were basically not able to make such statements based on the design.
