E-cigs Shut Down Lots of Immune System Genes—Regular Cigs Don’t

It’s widely assumed that swapping cigarette puffing for vapor huffing is better for health—after all, electronic cigarettes that heat up and atomize a liquid concoction can skip all the hazards of combustion and smoke. But researchers are still scrambling to understand the health effects of e-cig use (aka vaping) and to track down the variable and undisclosed components of those vaporized mixtures. The most recent data hints at unexpected health effects unique to e-cig use.

It seems the flavoring and other additives are the biggest issue. Most non-tobacco vape substances I’ve seen have been pure extracts without any additives. Now its possible things left over from the extraction process might be an issue but there’s not much research on that yet probably due to the legalities of it.  Cinnamaldehyde has very strong irritant properties (it directly activates one of the main sensors of nasty chemicals)…

If it suppresses the immune system, I wonder if vaping would actually be beneficial for those with autoimmune diseases? We automatically think of a weak immune system as “bad”, but some people’s immune system is so strong that it’s hurting/killing them.

Typical American Diet Can Damage Immune System

…Many reports have observed that heavier patients appear more likely to come down with infections during a hospital stay, acquire weaker protection from vaccinations and, as with River, suffer more complications from the flu.

Weight alone may not be the entire explanation. A tantalizing line of evidence suggests that unhealthful foods — fatty, salty, sugary, processed foods — may disrupt the body’s defenses in a way that promotes inflammation, infection, autoimmune diseases and even illnesses like cancer.

I think it was QI (highly recommended) where I heard about the study into hereditary genetics, how what grandparents ate was believed to affect grandchildren.

What Happens When You Get The Wrong Blood Type?

Being transfused with the wrong type of blood is incredibly rare, but it has occasionally happened. What does it feel like to have the wrong type of blood coursing through your veins?

Scared?  How about after reading this article suggesting that blood transfusions are overused.  The medical system being prudent about blood transfusions saves money, conserves blood for when necessary, and minimizes the possibility of getting the wrong blood type.

My understanding is that people on blood thinners are not permitting to donate blood, but if you are able to, please do.  Similarly, encourage those who can.
