The wisdom regarding the small intestine found in Donguibogam aligns remarkably well with modern science. The small intestine's role in separating clarity and turbidity is directly connected to our digestive and absorptive functions. Recent studies show that the function of the small intestine extends beyond simple digestion and absorption, serving as a key factor in overall metabolic regulation and energy balance.
Processed foods, particularly those containing excessive refined carbohydrates and sugars, are absorbed too rapidly in the small intestine, causing blood glucose to spike sharply. This sudden rise in blood glucose triggers an overproduction of insulin, leading to a steep drop in blood glucose. Our brain perceives this rapid hypoglycemia as an energy deficiency, which provokes further food cravings. This is the main reason we experience false hunger, feeling empty and hungry again even when full. Frequent blood sugar spikes and insulin resistance are primary culprits behind obesity, chronic fatigue, and lethargy.
Furthermore, these processed foods negatively impact the gut microbiota, or microbiome. As beneficial bacteria decrease and harmful bacteria proliferate, intestinal mucosal permeability increases, potentially leading to leaky gut syndrome. This triggers inflammatory responses and hinders nutrient absorption, leaving the body deprived of proper nourishment no matter how much you eat. Ultimately, this leads to mitochondrial hypofunction, impairing our cellular energy factories and worsening chronic fatigue.
A diet deficient in fiber poses another problem. Fiber helps nutrients absorb slowly in the small intestine and serves as fuel for beneficial gut bacteria, making it essential for cultivating a healthy intestinal environment. When fiber is lacking, satiety decreases and intestinal function declines, placing a heavier burden on the small intestine. Consequently, when the small intestine loses its proper function, the body continually senses hunger, fails to generate energy efficiently, and suffers from chronic fatigue. Caring for the health of our small intestine is not simply a matter of digestion, but an essential step toward restoring vitality.
