Autoimmune Disease and diet/supplements

Is there any good research surrounding diets/supplements for autoimmune diseases such as sjorgrens, RA, lupus? Curcumin for inflammation? Omega 3s (ocular) or acidic foods (oral) on sicca symptoms? Vitamin D? Etc

Alcohol and glucose

When we talk about lifestyle factors in diabetes managing we don’t often include alcohol. Can drinking alcohol lead to compromised blood glucose management in the long term? Does alcohol affect beta cell function and/or insulin sensitivity?

Nutrition/Supplements for Joint Health

Are there are any nutrients or supplements with good/ strong evidence for improving joint health? Most I find seem to have only a neutral or small positive impact (despite some places making very big claims, which seem unfounded; like collagen for example, where the evidence on it doing anything seems weak?).

Emulsifiers and health

Emulsifiers seem to be a common ingredient in processed foods. I've heard in-vitro studies claim that they may damage the layers of the GIT. What is the latest evidence on their effects on health, if any?

"Causal" Risk Factor

In SNP16 Alan uses the term "causal risk factor" a couple of times. Knowing how precise you guys are with language, inclusion of "causal" has got to be deliberate here. Can you please enlighten a newbie as to what specifically a "causal" risk factor is, and how that differs from other nutritional risk factors, if at all? Thanks.
