re: When people say "inflammation" what are they talking about?

Well that's part of the problem, people push their agendas and beliefs using a vague term like inflammation, but without specificity on what's inflamed it's mostly just nonsense.

For example, my quadricep tendon is inflamed because of my squat form so I have tendonitis, which is inflammation of a tendon. If someone has poor digestive health, they may have inflammation in their intestines. This is usually accompanied with bloating, gas, either constipation or diarrhea, or even pain. The fringes of the health community have begun to peddle this as explaining any kind of inflammation. They may be right, they may be wrong. There's not a ton of data out on it.
