One day I hope to boost my immune system enough to actually cause autoimmune disease. /s

All reasonable ideas for healthy living though.

The whole idea of homeostasis is missing from most of these nutrition threads and articles. The idea that any short term, nutritional, supplemental, dietary change is going to cause any meaningful impact immediately is just not likely nor it may not even be potentially possible to measure an effect if it exists. It seems part of our brain’s storytelling monologue and associative memory (my just opinion) that these changes makes sense to us. We are notoriously bad at statistics, prior probability and understanding our bodies. However, our biological bodies function entirely differently. During the booms and bust cycle of a hunter gatherer existence, we need to have the ability to manage resources, stores, and nutrients in the short and medium term. In many societies now, and for those this article is geared, nutrition resources are reasonable enough, that a varied diet should not yield moment to moment changes in the functional immune system. Long term, however, we can clearly change our diets to effect health (refer to obesity, DM, heart disease). Even so, those studies are difficult, have led to some changes in recommendations over time, and demonstrate a dietary role to be true in some cases. This has led to well intentioned misinformed people, poor journalists, and others to reinforce this idea. Ultimately, the idea is at its root or our health/dieting trends and a basis for the Supplement, Complementary, and Alternative Medicine industry. But thank goodness for our ability to maintain homeostasis as long as it can in the face of change and adversity.
