Is Dr. Gundry missing a key factor in the consequences of Leaky Gut, that it can also enable uptake of dangerous chronic viruses? Is that taking place, and how might it rank in importance in terms of impairing health compared to endotoxins and other microbial substances getting absorbed?

Yours is a key insight here in taking his hypothesis further in appreciating what is truly the major liability. Not only can all of the microbial byproducts like endotoxins that normally are excreted in the feces get absorbed and spread through the body when there is a breach of the mucosal lining, this is true for uptake of viruses present within the lumen of the gut and which only need to bypass the sentry consisting of the mucosal lining of the gastrointestinal tract. So this portal of entry is one of the key points of vulnerability exploited by viral pathogens that are ingested orally, such as the viruses doped in milk at the large-scale processing facilities. The interlopers know this will be distributed to many, many, humans of all ages. You are also recognizing that it is no coincidence lectins are a factor in overcoming barriers to uptake of viruses by the gut, that one of the culprits is gluten present widely in human diets because it is a constituent of wheat, and wheat, you have learned, is of extraterrestrial origin. It was brought to the Earth by the Extraterrestrial Alliance to be a meager source of nutrition and also a kind of Trojan horse of its own because of its unhealthy nature, despite the fact it contains calories and is usable as food.
