Inflammatory, autoimmune, chronic diseases: bad diet and physical inactivity are causes or effects?
It is now well established that most chronic diseases, especially those identified as inflammatory, are statistically correlated with some typical dietary excesses and physical inactivity. But do really these habits cause the diseases, or they result from them? Current opinion favours the first option, but fails to explain why the satisfaction of eating, naturally evolved in our brains to produce health, apparently induces countless millions of people to eat unrestrictedly until becoming mortally sick, whereas trying to keep a theoretically healthy diet is most often a real torture. The inverse explanation makes much more sense: since inflammation produces much heat, calorie-rich diets are required. An inflamed digestive tract lacks digestive power and is easily irritated or damaged by solid objects, therefore requiring a refined, concentrated, low-fibre diet. And inflamed or merely sick organisms are easily exhausted by physical effort, hence physical inactivity. This study confirms that, most probably, the primary causes of inflammatory diseases are always external inflammatory agents, like infectious micro-organisms or toxic substances, of which a particularly ubiquitous example is nicotine. High-calorie/low-fibre diets and physical inactivity are direct consequences of generalised inflammation. Inversely, in most cases, physical exercise and moderation in eating, by themselves, cannot substantially suppress inflammations, but they can prevent them from being further reinforced by the neural reward system. Moreover, diets and exercise causing important suffering will usually do more harm than good, especially to children and young people, not to mention pregnant or nursing women. Only the identification and elimination of the inflammatory agents can efficiently prevent and cure inflammatory diseases, and currently nicotine, absorbed intentionally or passively, from tobacco or other sources, must be considered the chief suspect because of its inflammatory power, ubiquity and addictive properties.
